Subject to the terms and conditions of this Agreement, Atea hereby grants to Roche under the Atea Patent Rights and Atea Know-How and Atea’s interest in the Joint Patent Rights and Joint Know-How:

The exclusivity of the above license is subject to the right of Atea and its respective Affiliates to conduct any activities expressly contemplated by this Agreement.

Subject to the terms and conditions of this Agreement, Roche hereby grants to Atea under the Roche Patent Rights and Roche Know-How and Roche’s interest in the Joint Patent Rights and Joint Know-How:

Notwithstanding anything to the contrary in this Article 2 or elsewhere in this Agreement, no licenses or rights are granted to Atea under any information, data, proprietary materials or other intellectual property rights whether or not patentable that are owned or controlled by [***].

For clarity, Atea retains the exclusive ownership and right to use any compound that was generated by or on behalf of Atea, or that is otherwise Covered by intellectual property rights Controlled by Atea, at the Effective Date or during the Agreement Term in the Excluded Field.

Notwithstanding anything to the contrary in this Agreement, Atea retains the sole right to develop, manufacture and commercialize Compounds and Products in the Atea Territory for the treatment of Dengue Fever, Japanese Encephalitis, West Nile Virus, Yellow Fever and/or Zika (the “Retained Indications”) in the Atea Territory, and to develop and manufacture Compounds and Products in the Roche Territory for the Retained Indications. Atea will notify Roche in writing promptly [***] for the Retained Indication in the Atea Territory. For [***] months after Roche’s receipt of such notice from Atea, the Parties will negotiate in good faith an amendment to this Agreement specifying the terms pursuant to which Roche will commercialize the Product in the Roche Territory for the Retained Indications, except if Roche decides to offer such commercialization right to Atea. Unless and until the Parties enter into such amendment, neither Party will have the right to commercialize the Product in the Roche Territory for the Retained Indications.

Each Party shall have the right to grant sublicenses to its Affiliates (through multiple tiers), and, as to Roche, [***] under its rights granted under Section 2.1 without prior approval of the other Party.

Each Party and its Affiliates shall have the right to grant written sublicenses to non-Affiliate entities (through multiple tiers) under its rights granted under Section 2.1 without prior approval of the other Party. Roche shall inform Atea promptly after the signature of any sublicense agreement it enters into under this Section 2.2.2.

Each sublicense shall be consistent in all material respects with the terms and conditions of the Agreement, provided that the sublicensing Party shall be responsible for the payment of all amounts due hereunder, and for all other obligations of its sublicensees under the Agreement as if such obligations were those of such Party.

Atea shall have a one-time option right to request that Roche co-promote each Product (other than for the Retained Indications), on a Product-by-Product basis, in the US on a royalty basis (each, a “Co-Promotion Option”), subject to the provisions of this Section 2.3, and conditioned on Roche and Atea or their respective Affiliates entering into a co-promotion agreement consistent with this Section 2.3. For purposes of this Agreement, “co-promote” and “co-promotion” shall refer to marketing, promotion, detailing and advertisement of a Product by the Parties under the relevant Regulatory Approvals and the same trademark(s). “Co-promote” and “co-promotion” shall not mean the sale, contracting or distribution of a Product. Additional supportive customer and field activities may be included in the agreement even if they are not related to promotion (i.e. medical or patient support services). Atea may exercise its Co-Promotion Option with respect to each Product by giving written notice thereof to Roche at any time at least [***] prior to expected

Regulatory Approval of such Product in the US. Upon Atea’s exercise of its Co-Promotion Option with respect to a Product the Parties shall negotiate in good faith and enter into a written co-promotion agreement (the “Co-Promotion Agreement”). In addition to any other terms agreed to by the Parties, the Co-Promotion Agreement shall contain the terms set forth in Appendix 2.3 hereto and other terms typically contained in agreements or the co-promotion of similar products in the US. Upon Atea exercising the Co-Promotion Option in accordance with this Section 2.3, the Parties shall coordinate all sales efforts and field activities in the US under the direction of the JSC, and such efforts and activities shall be more fully described in the Co-Promotion Agreement. Atea shall have the right to co-promote any Product with any Third Party, or to commercialize such Product itself, in the Atea Territory, unless and until Atea exercises its Co-Promotion Option and the Parties enter into the Co-Promotion Agreement. If Atea exercises its right to co-promote or commercialize with a Third Party, then its Co-Promotion Option expires on the date any such Third Party agreement takes effect.

Atea shall have the right to subcontract the performance of any of its activities under the Agreement (including the activities described under the Global Development Plan and, if applicable, in the Co-Promotion Agreement), provided that (a) Atea shall be and remain responsible and liable for the performance of any such activities by any such subcontractor and (b) such subcontractor must be bound by written obligations (i) of nondisclosure and non-use that are as protective of Roche’s Confidential Information as this Agreement and (ii) to assign or license and transfer to Atea all right, title and interest to any Invention that is developed or, conceived and reduced to practice by such subcontractor that is related to the Compound or Product.

Atea may not subcontract out its activities under the Global Development Plan to any Third Party other than those Third Parties listed on Appendix 3, which Appendix lists Third Party subcontractors of Atea existing as of the Effective Date, or pursuant to the following procedure: (i) Atea shall notify [***] (which notice may be provided via e-mail) of any such proposed Third Party subcontractor and the scope of work proposed to be subcontracted (such notice, a “Subcontractor Notice”); (ii) Roche may notify Atea of any reasonable concerns with respect to such proposed subcontractor, if any, as expeditiously as practical but in no event later than [***] days of receipt of such Subcontractor Notice; (iii) Atea shall consider any such concerns in good faith; and (iv) if thereafter Atea continues to desire to use such Third Party subcontractor the matter shall be referred to the JOC for discussion and resolution. Notwithstanding the foregoing, Atea shall have the right, without needing to so notify [***] and seek Roche’s prior approval, to subcontract non-crucial activities under the Global Development Plan to Third Parties that would reasonably be acceptable to Roche if the total fees under the subcontract agreement do not exceed [***] and the activities being subcontracted are [***].

Roche shall have the right to subcontract the work performed under this Agreement without prior approval of Atea, provided that (A) Roche shall be and remain responsible and liable for the performance of any such activities by any such subcontractor and (B) such subcontractor must be bound by written obligations (i) of nondisclosure and non-use that are as protective of Atea’s Confidential Information as this Agreement and (ii) to assign or license and transfer to Roche all right, title and interest to any Invention that is developed or, conceived and reduced to practice by such subcontractor that is related to the Compound or Product.

Until [***] and subject to Section 2.1.4, Atea shall work exclusively with Roche with regard to Compounds and Products and will not, either on its own or in collaboration with a Third Party, research, develop or commercialize Compounds or Products in the Field other than pursuant to this Agreement, provided that the foregoing shall not limit Atea’s ability to engage subcontractors as provided in Section 3 or, in case Atea does not exercise its Co-Promotion Option as provided in Section 2.3, to engage co-promotion partners or other Third Parties to conduct commercialization activities in the Atea Territory.

Promptly after the Effective Date of this Agreement, the Parties shall establish a JSC to oversee the development, marketing and commercialization activities under this Agreement.

The JSC shall be composed of up to [***] persons (“Members”). Roche and Atea each shall be entitled to appoint up to [***] Members with appropriate seniority and functional expertise. Each Party may replace any of its Members and appoint a person to fill the vacancy arising from each such replacement. A Party that replaces a Member shall notify the other Party at least [***] days prior to the next scheduled meeting of the JSC. Both Parties shall use reasonable efforts to keep an appropriate level of continuity in representation. Both Parties may invite a reasonable number of additional experts or advisors to attend part or the whole JSC meeting with prior notification to the JSC provided that such experts or advisors are bound by written obligations (i) of nondisclosure and non-use that are as protective of each Party’s Confidential Information as this Agreement and (ii) to assign or license and transfer to the relevant Party all right, title and interest to any Invention that is developed or, conceived and reduced to practice by such experts or advisors that is related to the Compound or Product. Members may be represented at any meeting by another person designated by the absent Member. The JSC shall be co-chaired by a Member from Atea and a Member from Roche. The Atea and Roche co-chairs will alternate each JSC meeting the lead co-chair responsibilities associated with that meeting (each, a “Lead Co-Chairperson”).

The JSC shall have no responsibility and authority other than that expressly set forth in this Section.

The Lead Co-Chairperson or his/her delegate will be responsible for sending invitations and agendas for all JSC meetings to all Members at least [***] days before the next scheduled meeting of the JSC. The venue for the meetings shall be agreed by the JSC. The JSC shall hold meetings at least once every [***], either in person or by tele-/video-conference, and in any case as frequently as the Members of the JSC may agree shall be necessary. The Alliance Director of each Party may attend the JSC meetings as a permanent participant but shall not be a Member unless appointed as such.

Subject to the terms and conditions of this Agreement, and except as otherwise provided in Article 6, the Parties shall jointly develop the Products in the Territory in accordance with the Global

Development Plan and under the governance of the JSC. The responsibility of Roche and Atea to operationalize the global clinical development will be described in the Global Development Plan. The Global Development Plan shall be regularly amended and updated. Roche and Atea shall each use Commercially Reasonable Efforts to perform their respective tasks and obligations in conducting all activities ascribed to them in the then-current Global Development Plan, in accordance with the time parameters set forth therein. The Parties will share the costs associated with activities conducted under the Global Development Plan. FTE Costs and Out of Pocket Expenses incurred by or on behalf of either Party or any of its Affiliates in connection with its activities under the Global Development Plan[***] shall be shared equally (50/50) by the Parties, [***]. Neither Party shall pursue Third Party funding for any Clinical Study under the Global Development Plan that is not an Atea Ongoing Study without the approval of the JSC.

The Parties shall disclose and make available to each other all data and information necessary to conduct the development activities under the Global Development Plan. The Parties shall answer any questions reasonably posed by the other Party and provide any information reasonably requested by the other Party.

Prior to initiating a new Clinical Study (including, for the purposes of this Section, any marketing studies, Post-Approval Commitment Studies, and Phase IV Studies for the Product) that is not an Ongoing Atea Study and is not an ongoing Unilateral Study (as defined below) or included in the then-current Global Development Plan, the Party that desires to conduct such Clinical Study (the “Proposing Party”) shall propose such Clinical Study to the JOC, which proposal shall include a synopsis of the protocol for such Clinical Study and an estimated budget for such Clinical Study. If the JOC agrees that the Parties should conduct such Clinical Study, then the Parties shall amend the Global Development Plan to include such Clinical Study. If the JSC does not agree that the Parties should conduct such Clinical Study, then the Proposing Party shall have the right, but not the obligation, to conduct such Clinical Study at its sole expense (each such Clinical Study, a “Unilateral Study”), provided that (i) [***], and (ii) [***]. For clarity, neither Party shall have the obligation to conduct or, except as may be required by Applicable Law or ethical requirements, complete any Unilateral Study.

Notwithstanding anything to the contrary in the foregoing, the Party which is not the Proposing Party, after good faith discussion in the JSC, shall have the right to require the Proposing Party to not conduct a proposed Unilateral Study, if [***] such Unilateral Study [***].

With respect to each Unilateral Study, if the Party not performing such Unilateral Study uses any data or results from such Unilateral Study to obtain, maintain or expand any Regulatory Approval or any pricing or reimbursement for, otherwise includes such data or results in the label for, or uses such data and results to commercialize, a Product in its Respective Territory, then such non-performing Party shall reimburse the Party that performed such Unilateral Study for [***] incurred by or on behalf of such performing Party or any of its Affiliates in connection with such Unilateral Study to the extent such costs are not funded by a Third Party. Notwithstanding the foregoing, the submission of data and results from a Unilateral Study to a Regulatory Authority only for safety reporting purposes in connection with periodic safety reporting or as a courtesy copy shall not result in a reimbursement obligation under this paragraph. The Party not performing the applicable Unilateral Study shall promptly notify the performing Party of any use of the data or results of such Unilateral Study that would result in a reimbursement obligation under this paragraph.

To the extent the JSC determines that an intravenously-administered formulation of the Lead Compound (an “IV Lead Compound Formulation”) is required for Clinical Studies for Hospitalized Patients, Roche may develop an IV Lead Compound Formulation. [***]. To the extent the JSC does not endorse the development of an IV Lead Compound Formulation, then Roche may, at its own cost and expense, develop such IV Lead Compound Formulation. In each case, for [***], Atea will supply Roche with GMP API for use in the development of the formulation of the IV Lead Compound Formulation and for clinical supply of IV Lead Compound Formulation as provided in Section 8.1.

Each Party shall maintain records of its activities under the Global Development Plan and for Clinical Studies, Post-Approval Commitment Studies and Phase IV Studies of Product conducted pursuant to this Agreement outside the Global Development Plan (or cause such records to be maintained) in sufficient detail and in good scientific manner as will properly reflect all work done and results achieved by or on behalf of such Party in the performance of the development.

The JSC will evaluate from time to time whether any non-clinical or clinical studies should be conducted for Back-Up Compounds. If the JSC determines to pursue development of Back-Up Compounds for potential development if the Lead Compound demonstrates material safety or efficacy concerns, the Parties shall agree on an adjustment to the Global Development Plan and the Global Development Plan Budget to reflect such additional activities.

Atea shall have the right and the responsibility for all regulatory affairs related to Products in the Atea Territory, including the preparation and filing of applications for Regulatory Approval (other than for manufacturing by Roche or its CMO or other Third Party manufacturer) in the Atea Territory (for clarity, for Unilateral Studies conducted by Roche in the Atea Territory, Atea shall transfer responsibility for the conduct of such studies to Roche). Roche shall have the right to participate in all regulatory interactions, as well as in the preparations therefor, as an observer, other than for Products for the Retained Indications, where permitted by such Regulatory Authority. All regulatory filings for all Products in all countries of the Atea Territory (other than regulatory filings for manufacturing by Roche or its CMO or other Third Party manufacturer) and all data related thereto shall be owned by Atea, its Affiliates or licensees.

Atea shall also be solely responsible for all regulatory affairs related to the conduct of the Atea Ongoing Studies until hand-over of responsibility therefor to Roche as determined by the JSC, any Unilateral Studies conducted by Atea in the Roche Territory, and all Clinical Studies of Products in the Roche Territory for the Retained Indications. Atea shall provide reasonable advance notice of any meeting with any Regulatory Authority in the Roche Territory related to the Atea Ongoing Studies or Unilateral Studies conducted by Atea, and Roche shall have the right, at its own discretion, to participate in any such meeting with Regulatory Authorities in the Roche Territory.

Roche shall have the right and the responsibility for all regulatory affairs related to Products in the Roche Territory, including the preparation and filing of applications for Regulatory Approval in the Roche Territory (other than for Unilateral Studies, Clinical Studies for the Retained Indications

and, until hand-over of responsibility to Roche as determined by the JSC, Atea Ongoing Studies, in each case conducted by Atea in the Roche Territory). Atea shall have the right to participate in all regulatory interactions, as well as in the preparations therefor, as an observer, where permitted by such Regulatory Authority. All regulatory filings for all Products in all countries of the Roche Territory (other than regulatory filings for the Atea Ongoing Studies conducted by Atea in the Roche Territory prior to hand-over, and all Clinical Studies for the Retained Indications) and all data related thereto shall be owned by Roche, its Affiliates or licensees.

Roche shall also be solely responsible for all regulatory affairs related to the conduct of any Unilateral Studies conducted by Roche in the Atea Territory. Roche shall provide reasonable advance notice of any meeting with any Regulatory Authority in the Atea Territory related to the Unilateral Studies conducted by Roche, and Atea shall have the right, at its own discretion, to participate in any such meeting with Regulatory Authorities in the Atea Territory.

At a date to be defined by the JSC, Atea shall transfer to Roche all (i) regulatory filings in its possession and control relating to the Product in the Field in the Roche Territory (other than for Unilateral Studies conducted by Atea in the Roche Territory, and Clinical Studies of Product in the Retained Indications in the Roche Territory), (ii) copies of all relevant historical clinical data for the Product in the Field in the Roche Territory, (iii) copies of all material correspondence with the Regulatory Authorities for the Product in the Field in the Roche Territory, (iv) copies of regulatory dossiers containing information necessary or useful to Roche in connection with its regulatory filings for all Products in the Field in the Roche Territory, including, but not limited to clinical trial dossiers, regulatory correspondence, Regulatory Authority meeting minutes and study reports from completed non-clinical and clinical studies, and (v) comprehensive electronic Clinical Study, Post-Approval Commitment Study and Phase IV Study data relevant to the Product in the Field in an appropriate format.

Roche shall assist Atea in conducting any required GMP audit related to the above-mentioned documentation. Atea shall have the right to use all data and documents provided to Atea under this paragraph in its own filings and interactions with Regulatory Authorities for the Product in the Field in the Atea Territory, and for Unilateral Studies, Clinical Studies for the Retained Indications, and Atea Ongoing Studies until

hand-over of responsibility to Roche, in each case conducted by Atea in the Roche Territory, also in the Roche Territory.

In the event a Party cannot conduct regulatory activities independent of the other Party which would be needed to pursue Regulatory Approval of Products in the Roche Territory (for Roche) or the Atea Territory (for Atea), the other Party shall use Commercially Reasonable Efforts to assist the first Party and/or conduct any such regulatory activities on the first Party’s behalf at the first Party’s cost and expense.

Atea shall have, and Roche hereby grants to Atea, a right of reference and access to the regulatory filings for Product made by Roche in the Roche Territory, for the purpose of making regulatory filings in the Atea Territory for Product. Roche shall have, and Atea hereby grants to Roche, a right of reference and access to the regulatory filings for Product made by Atea in the Atea Territory, for the purpose of making regulatory filings in the Roche Territory for Product.

Notwithstanding the foregoing, Atea shall have the right and the responsibility for all regulatory affairs related to Products in the Territory for the Retained Indications, including the preparation and filing of applications for Regulatory Approval in the Retained Indications in the Territory.

The Parties shall execute a separate pharmacovigilance agreement as deemed applicable as soon as practicable after the Effective Date, but no later than the Initiation of the first Phase III Study in the Roche Territory or the first Regulatory Approval in the Roche Territory after the Effective Date (whichever comes first). Such pharmacovigilance agreement shall set forth the responsibilities and obligations of the Parties with respect to the procedures and timeframes for compliance with the applicable laws and regulations pertaining to safety reporting of the Product(s) and their related activities.

Atea shall have the responsibility for supplying API for technical development, as well as for clinical supply of the Products for the Field in the Territory for [***], and [***] of such supply by Atea, other than for the Atea Ongoing Studies and any Unilateral Study conducted by Atea, shall be [***]. Notwithstanding the foregoing, Roche will have the right to take over any part of the manufacture and supply of the Product for the Field in the Roche Territory at any time during [***]. The Parties will meet during [***] to discuss and decide on a hand-over plan of supply responsibilities in order to ensure a seamless continuation of manufacturing and supply beyond [***].

[***], after [***], Atea will remain responsible, at its own expense, for the manufacture and supply of clinical supplies of the Products for any Unilateral Study conducted by Atea and any Atea Ongoing Studies, and Roche shall be responsible at its own expense for the manufacture and supply of clinical supplies of the Products for sites included in the Clinical Studies conducted pursuant to the Global Development Plan other than any Atea Ongoing Studies, and for all sites for any Unilateral Study conducted by Roche. Notwithstanding the foregoing, the Parties will use

Commercially Reasonable Efforts to ensure that the clinical supply of Products for use in the Field is obtained in a manner that is cost efficient and practical, which may include utilizing the other Party or the other Party’s CMO or other Third Manufacturer, as applicable.

Atea shall initiate within [***] days of the Effective Date a technology transfer to Roche in accordance with the plan set forth in Appendix 8.1.3 (as may be revised by mutual consent of the Parties) to enable Roche (or Roche’s designee(s)) to manufacture Compounds and Products using the First Generation Process.

In addition, within [***] days after completion of the Early Second Generation Process Development for the Second Generation Process, Atea shall initiate substantially the same technology transfer to Roche with respect to the Second Generation Process to enable Roche (or Roche’s designee(s)) to conduct the Later Process Development for the Second Generation Process in accordance with a mutually agreed technology transfer plan. Atea shall inform Roche regularly at the JMC about its development efforts regarding the Second Generation Process, including about Atea's interactions with Third Parties that are involved in such development efforts. In addition, and upon Roche’s request, Atea shall provide Roche with all information and documents regarding such development efforts. In case the JSC decides to use the Second Generation Process for commercial supply, Atea shall complete within [***] days substantially the same technology transfer to Roche as for the First Generation Process with respect to the Second Generation Process to enable Roche (or Roche’s designee(s)) to conduct the Later Process Development for the Second Generation Process in accordance with a mutually agreed technology transfer plan.

Roche shall be responsible for the manufacture of commercial supplies of the Product for use in the Field in the Territory. Atea shall order all commercial supplies of the Product for use in the Field for the Atea Territory from Roche. Unless otherwise agreed by the Parties, within [***] days after the Effective Date, the Parties will negotiate in good faith and enter into a written supply agreement for the commercial supply of Products for use in the Field by Roche to Atea, with a related quality agreement providing for commercial supply of Product for use in the Field by Roche to Atea as the primary supplier and on the terms set forth in Appendix 8.2 hereto and other reasonable and customary terms (the “Supply Agreement”).

Promptly after the Effective Date, each Party will prepare an initial good faith [***] rolling forecast of its demand, split into [***] buckets, in the Atea Territory or the Roche Territory (as applicable) for the Product for commercialization purposes in the Field (each a “Demand Forecast Plan”). The Parties shall discuss and align the Demand Forecast Plans for consolidation to be presented and approved at the JSC.

In the event of a Roche Inability to Supply, following discussion between the Parties, solely during the pendency of such Roche Inability to Supply (unless otherwise agreed by the Parties, such agreement not to be unreasonably withheld), Atea may engage its own CMO(s) for commercial supply of the Product for use in the Field for the Atea Territory to the extent in accordance with

the Demand Forecast Plan and according to Roche’s Safety, Security, Health and Environmental Protection (SHE) and GMP standards.

Atea shall have the responsibility at its own expense for the development of the Second Generation Process until the manufacture of a batch of at least [***] of Drug Substance is achieved, consisting of [***], using the Second Generation Process and meeting the applicable Specifications (the “Early Second Generation Process Development”). Roche will cooperate with and provide reasonable consultative and in-kind support of such Early Second Generation Process Development at its own expense.

Subject to Atea’s technology transfer obligations pursuant to Section 8.1.3, Roche shall have the responsibility [***] for (a) any further development and scale-up of the First Generation Process (“First Generation Process Development”), (b) the development and scale-up of the Second Generation Process after the Early Second Generation Process Development (the “Later Second Generation Process Development”), and (c) scale-up of global commercial manufacturing of Drug Product (“Commercial Scale-Up”). Atea will cooperate with and provide reasonable consultative and in-kind support of such First Generation Process Development, Later Second Generation Process Development and Commercial Scale-Up [***].

The Parties will mutually agree in good faith on the manufacturing and release specifications, including without limitation testing methods and acceptance criteria, for Drug Substance and Drug Product, for each of the First Generation Process and the Second Generation Process (for the Second Generation Process as further specified in Appendix 8.3.3), in each case as updated by the JSC from time to time (the “Specifications”). Each Party shall be solely responsible for establishing the specifications for packaging and labeling of finished Drug Product in its Respective Territory.

The Parties will collaborate and strive for consensus decision making on matters relating to First Generation Process Development, Early Second Generation Process Development, Later Second Generation Process Development, Commercial Scale-Up, Specifications and the choice of whether to use the First Generation Process or Second Generation Process for commercial manufacturing of Drug Substance, through the JMC. If the Parties are unable to agree on any such matters, the matter will be escalated to the JSC.

Notwithstanding anything to the contrary in this Article 8, Atea shall have the sole right and responsibility for the supply of Compound and Product in the Territory for the Retained Indications at its own cost, unless the Parties otherwise agree in writing.

Roche, at its own expense, shall have the sole responsibility and decision-making authority for the marketing, promotion, sale and distribution of Products in the Field in the Roche Territory.

Atea, at its own expense, shall have the sole responsibility and decision-making authority for the marketing, promotion, sale and distribution of Products in the Atea Territory (subject to Section 2.3 and any Co-Promotion Agreement).

The JOC will review the Parties’ commercialization plans for their Respective Territories for Product for use in the Field, to monitor brand messaging and to make recommendations for consistency and optimization of such messaging. Atea shall in good faith consider reasonable comments from Roche relating to commercialization plans for the Product in the Field in the Atea Territory, made through the JOC or JSC.

The Parties will consider in good faith any global guidelines and strategy for pricing agreed to by the JSC (which shall be non-binding) in establishing pricing of Products. Notwithstanding any provision to the contrary set forth in this Agreement, all decisions for each Product related to any pricing matter, including list price, targeted net pricing, sales-weighted average discounts and rebates, pricing strategy (including the approach to pricing with different types of accounts and plans, including types of discounts and rebates), any non-U.S. equivalents of all of the foregoing, and modifications to any of the foregoing, will be solely made by (a) Roche for the Roche Territory and (b) Atea for the Atea Territory.

Roche shall use Commercially Reasonable Efforts to pursue further development and commercialization of Products in the Field in the Roche Territory (other than for the Retained Indications, unless and until the Parties enter into an amendment pursuant to Section 2.1.4). Atea shall use Commercially Reasonable Efforts to pursue further development (and commercialization, in case Atea exercises its Co-Promotion Option) of Products in the Field in the Atea Territory (other than for the Retained Indications). Roche shall be deemed to use Commercially Reasonable Efforts if Roche develops and commercializes at least one Product in at least one Indication. Roche (and its Affiliates) shall not be obliged to seek to market such Product in every country or seek to obtain Regulatory Approval in every country of the Roche Territory. As a result, the exercise of diligence by Roche is to be determined by judging Roche’s Commercially Reasonable Efforts in the Roche Territory, taken as a whole.

Within [***] days after the Effective Date and receipt of an invoice from Atea, Roche shall pay to Atea three hundred and fifty million US Dollars (US$ 350,000,000).

Roche shall pay up to a total of three hundred and thirty million US Dollars (US$ 330,000,000) in relation to the achievement of development and regulatory events with respect to Products. The

development and regulatory event payments under this Section 10.2 shall be paid by Roche according to the following schedule of development and regulatory events:

Each development and regulatory event payment shall be paid only once, the first time that any Product reaches the applicable triggering event and receipt of an invoice, regardless of the number of times such events are reached and by how many Products, subject to Section 10.5.

Upon reaching development and regulatory events (or in the case of manufacture by Atea of a Qualifying Second Generation Batch, receipt of notice by Roche from Atea that Atea has reached such development and regulatory event and confirmation by Roche of the same), Roche shall notify Atea within [***] days of the achievement of each milestone event described in this Section 10.2 and shall be paid by Roche to Atea within [***] days after receipt of an invoice from Atea.

Roche shall pay to Atea up to a total of three hundred and twenty million US Dollars (US$ 320,000,000) based on Calendar Year Net Sales of a Product in the Roche Royalty Territory:

Each of the sales-based event payments shall be paid no more than once [***] days after the end of the Calendar Quarter in which the event first occurs for the Product in the Roche Royalty Territory first reaching the respective Calendar Year Net Sales threshold and receipt of an invoice from Atea, and shall be non-refundable

On a Product-by-Product and country-by-country basis, Roche shall pay to Atea royalties on Net Sales of Products in such country in the Roche Royalty Territory during the relevant Royalty Term. Thereafter, the licenses granted to Roche for a given Product in such country shall be fully paid up, irrevocable and royalty-free.

The following royalty rates shall apply to the respective tiers of aggregate Calendar Year Net Sales of a Product in the Roche Royalty Territory, on an incremental basis, as follows:

For example, if Net Sales of a Product in the Roche Royalty Territory for a given Calendar Year are US$ [***] million, and such Product is a Patent Product, then royalties owed to Atea on such Net Sales of such Product for that Calendar Year shall equal US$ [***] calculated as follows:

For the purpose of calculating royalties for a Product, Calendar Year Net Sales and the royalty rates shall be subject to the following adjustments, as applicable:

If Roche or its Affiliates intend to sell a Combination Product, then the Parties shall meet approximately [***] prior to the anticipated First Commercial Sale of such Combination Product in the Territory to negotiate in good faith and agree to an appropriate adjustment to Net Sales to reflect the relative commercial value contributed by the components of the Combination Product (the “Relative Commercial Value”). If, after such good faith negotiations not to exceed [***] days, the Parties cannot agree to an appropriate adjustment, the dispute shall be initially referred to the executive officers of the Parties in accordance with Section 21.2.

If the Parties are unable to agree on the Relative Commercial Value within [***] days of such referral, then the Relative Commercial Value shall be determined by the following procedure. Roche will select [***], Atea will select [***], and those [***] individuals shall select [***] and who shall be chairman of a committee of the [***] Experts (the “Expert Committee”), each with a single deciding vote. The Expert Committee will promptly hold a meeting to review the issue under review, at which it will consider memoranda submitted by each Party at least [***] days before the meeting, as well as reasonable presentations that each Party may present at the meeting. The determination of the Expert Committee as to the issue under review will be binding on both Parties. The Parties will share equally in the costs of the Expert Committee. Unless otherwise agreed to by the Parties, the Expert Committee may not decide on issues outside the scope mandated under terms of this Agreement.

then the royalty payments due to Atea for such Product in such country shall be reduced by [***]. If both a) and b) have occurred, then the Royalty Term for such Product in such country shall end (unless the Royalty Term had expired prior to such time for a given Product in a given country),

royalties shall no more be due by Roche in such country for such Product, and the license in that country for such Product shall be fully paid-up and irrevocable.

Compulsory Sublicense Compensation received by the Roche Group from a Compulsory Sublicensee during the Royalty Term for a Product in a country shall be shared with Atea on an equivalent profit share percentage (the “Compulsory Profit Share Percentage”) calculated for the respective Calendar Year as follows:

At the end of the Calendar Year, Roche shall pay to Atea the [***]. For clarity, any sales or payments by Compulsory Sublicensees under a Compulsory Sublicense shall not be considered as Net Sales and shall not give rise to any royalty payment under Section 10.4.2 of this Agreement.

In case the JSC decides to pursue development or commercialization of a Product that contains a [***], then at the time such decision is made, the Parties shall discuss in good faith any reasonable adjustments that may be appropriate to make to the payments from Roche to Atea based on Sections 10.2, 10.3, and 10.4, prior to commencement of any such activities, subject to the following sentence. [***].

[***] shall be responsible for and pay or have paid the entire consideration owed to any Third Party in relation to [***]. To the extent [***] fails to make any [***] when due, [***] may make such payment to the applicable Third Party [***]. In such event, or if [***] as provided in [***] or enters into a [***] as provided in [***] and makes [***] thereunder, [***] may request [***] as provided in [***] or [***] of such [***] under this Agreement.

The responsibility for payment of consideration owed to any Third Party in relation to [***] shall be [***]. The Party making [***] shall be [***] (or, in the case of [***]).

In the event that both [***] and [***] are made under the same agreement with the same Third Party and cannot be clearly distinguished from each other, then the Parties will discuss in good faith and agree on which part of such payments is attributable to [***] or [***]. If, after such good faith negotiations not to exceed [***] days, the Parties cannot agree to an appropriate allocation, the dispute shall be initially referred to the executive officers of the Parties in accordance with Section 21.2. If the Parties are unable to agree on the allocation within [***] days of such referral, then such allocation shall be determined by the procedure described in the second paragraph of Section 10.4.3.

Each Party acknowledges that the other Party may be obligated to disclose this financial arrangement, including all fees, payments and transfers of value, as may be advisable or required under Applicable Law, including the US Sunshine Act.

Roche shall calculate royalties on Net Sales quarterly as of March 31, June 30, September 30 and December 31 (each being the last day of an “Accounting Period”) and shall share with Atea within [***] days after the end of each Accounting Period in which Net Sales occur a good faith estimate of the royalties payable to Atea for such Accounting Period. Within [***] days after the end of each Accounting Period, Roche shall pay the royalties on Net Sales to Atea in line with the finally reported Net Sales for each Calendar Quarter as set forth in Section 11.6, which finally reported Net Sales (i) Roche shall report to Atea during such time period, (ii) may deviate from the good faith estimate provided earlier, and (iii) shall be relevant for the purposes of calculating the royalty owed under Section 10.4.

Any payment under this Agreement that is not paid on or before the date such payment is due shall bear interest, to the extent permitted by Applicable Law, at [***] percentage points above the [***], as reported by Reuters from time to time, calculated on the number of days such payment is overdue.

Royalties on Net Sales shall be paid by Roche in US Dollars (the “Payment Currency”) to account(s) designated by Atea. All other amounts payable by a Party to the other Party hereunder shall be paid in the Payment Currency to account(s) designated by the other Party.

When calculating the Sales of any Product that occur in currencies other than the Payment Currency, Roche shall convert the amount of such sales into Swiss Francs and then into the Payment Currency using Roche’s then-current internal foreign currency translation method actually used on a consistent basis in preparing its audited financial statements (at the Effective Date, YTD average rate as reported by Reuters).

In a given country, if by reason of Applicable Law (for example governmental restrictions on foreign exchange trade) the local currency is blocked and cannot be removed from such country, Roche will notify Atea in writing and

With each royalty payment Roche shall provide Atea in writing for the relevant Calendar Quarter on a Product-by-Product basis the following information:

For reimbursement of Out of Pocket Expenses and FTE Costs incurred by or on behalf of either Party or any of its Affiliates in connection with its activities under [***], as soon as practicable after the end of each Calendar Quarter, but in any event no later than [***] days after the end of each such Calendar Quarter, each Party shall share with the other Party a good faith estimate of such reimbursable costs incurred by such Party. In no event later than [***] days after the end of such Calendar Quarter each Party shall update the good faith estimate to reflect changes in the Out of Pocket Expenses and FTE Costs (each, a “Reconciliation Interim Report”), together with reasonable supporting documentation for such costs. Each Party shall have [***] days after the delivery of the other Party’s Reconciliation Interim Report to review and ask questions.

Within [***] days following the end of such Calendar Quarter, each Party shall update its Reconciliation Interim Report to reflect the final amounts and the Parties shall coordinate to aggregate the reports to calculate the total amount to be reimbursed under this Agreement (“Reconciliation Final Report”). The Party that owes payment to the other Party pursuant to the Reconciliation Final Report shall pay such amount (to the extent not subject to a good faith dispute) within [***] days after receipt of an invoice from the Party that is due payment.

For all amounts for which a Party (the “Owing Party”) is obligated to reimburse or pay the other Party (the “Owed Party”) pursuant to this Agreement for which no specific provision is provided hereunder regarding how such payment shall be made, the Owed Party shall send to the Owing Party an invoice for such amount within [***] days after the Owed Party’s determination that such amount is payable by the Owing Party, which invoice shall include a reference to the section of this Agreement under which the Owed Party is requesting reimbursement or payment and be accompanied by reasonable documentation of the incurrence or accrual of the costs to be reimbursed. Payment with respect to each such invoice shall be due within [***] days after receipt by the Owing Party thereof.

All payments provided for in this Agreement are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any such payments, the paying Party shall pay such Indirect Taxes at the applicable rate in respect of any such payments following the receipt, where applicable, of an Indirect Taxes invoice issued by the payee Party in respect of those payments. The Parties shall cooperate in good faith to minimize Indirect Taxes addressed in this Section 12.1 in accordance with Applicable Law.

Each Party shall be entitled to deduct and withhold from any amounts payable under this Agreement such taxes as are required to be deducted or withheld therefrom under any provision of Applicable Law; provided, however, that [***]. The Party that is required by Applicable Law to make such deduction or withholding shall deduct such amounts from such payment, promptly pay such amount on behalf of the other Party to the proper governmental authority, and promptly furnish the other Party with proof of payment on a timely basis following such payment. [***].

Each Party agrees to reasonably assist the other Party in claiming refunds or exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted.

Each Party receiving payments under this Agreement shall provide to the other Party, at the time or times reasonably requested by such other Party or as required by Applicable Law, such properly completed and duly executed documentation (for example, IRS Form W-9 or applicable Form W-8) as will permit payments made under this Agreement to be made without, or at a reduced rate of, withholding for taxes.

Roche shall keep, and shall require its Affiliates and Sublicensees to keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all royalties payable under this Agreement. Such books of accounts shall be kept at their principal place of business. Atea shall, at its own expense, have the right to engage an internationally recognized independent public accountant reasonably acceptable to Roche to perform, on behalf of Atea, an audit of such books and records of Roche and its Affiliates that are deemed necessary by the independent public accountant to report on Net Sales of Product for the period or periods requested by Atea and the correctness of any financial report or payments made under this Agreement.

The auditors shall only state factual findings in the audit reports and shall not interpret the agreement. The auditors shall share all draft audit findings with Roche before sharing such findings with Atea and before the final audit report is issued. The final audit report shall be shared with Roche at the same time it is shared with Atea.

If the audit reveals an overpayment, Atea shall reimburse Roche for the amount of the overpayment within [***] days. If the audit reveals an underpayment, Roche shall make up such underpayment with the next royalty payment or, if no further royalty payments are owed by Roche, Roche shall reimburse Atea for the amount of the underpayment within [***] days. Roche shall pay for the audit costs if the underpayment of Roche exceeds [***] of the aggregate amount of royalty payments owed with regard to the royalty statements subject to the audit. Section 11.2 shall apply to this Section 13.3.

Atea shall own all Atea Inventions, Roche shall own all Roche Inventions, and Atea and Roche shall jointly own all Joint Inventions. Atea and Roche each shall require all of its employees to assign all inventions related to Products made by them to Roche and Atea, as the case may be.

The determination of inventorship for Inventions shall be in accordance with US inventorship laws as if such Inventions were made in the US.

Subject to the licenses granted under this Agreement, Atea and Roche will each have an equal undivided share in the Joint Patent Rights, without obligation to account to the other for exploitation thereof, or to seek consent of the other Party for the grant of any license thereunder. Each Party hereby waives any right it may have under the laws of any jurisdiction to require such approval, consent or accounting with respect to jointly owned Inventions and Joint Patent Rights. Each Party hereby grants to the other party a nonexclusive, royalty-free (except as provided in this Agreement), worldwide license, with the right to grant sublicenses through multiple tiers (except as otherwise expressly provided in this Agreement) under their undivided interest in jointly owned Inventions and Joint Patent Rights to exploit jointly owned Inventions.

Except as specifically set forth herein, this Agreement shall not be construed as (i) giving any of the Parties any license, right, title, interest in or ownership to the Confidential Information; (ii) granting any license or right under any intellectual property rights; or (iii) representing any commitment by either Party to enter into any additional agreement, by implication or otherwise.

With respect to Know-How (other than Inventions) generated pursuant to the Global Development Plan, Atea shall own such Know-How made by employees of Atea solely or jointly with a Third Party, Roche shall own such Know-How made by employees of the Roche Group solely or jointly with a Third Party, and the Parties shall jointly own such Joint Know-How.

In accordance with the German Statute on Employees Inventions, each Party agrees to claim the unlimited use of any Invention conceived, reduced to practice, developed, made or created in the performance of, or as a result of, any activities conducted under the Agreement by employees of any German Affiliates. For the avoidance of doubt, each Party is responsible for fulfilling the obligations towards their employees under the German Statute of Employee’s Inventions.

Where the Parties need to consult with each other on the Handling of Patent Rights, the Parties shall establish a patent coordination team and shall adopt procedures for interacting on patent matters.

It is the intention of the Parties that this Agreement is a “joint research agreement” as that phrase is defined in 35 USC § 102(c) (AIA). In the event that either Party to this Agreement intends to overcome a rejection of a claimed invention covered by Joint Patent Rights or the Atea Patent Rights pursuant to the provisions of 35 USC §§ 102(a)-(d), such Party shall first obtain the prior written consent of the other Party. Following receipt of such written consent, such Party shall limit any amendment to the specification or statement to the patent office with respect to this Agreement to that which is strictly required by the applicable subsection of 35 USC § 102 and the rules and regulations promulgated thereunder and which is consistent with the terms and conditions of this Agreement (including the scope of the Global Development Plan). To the extent that the Parties agree that, in order to overcome a rejection of a claimed invention covered by Joint Patent Rights or the Atea Patent Rights pursuant to the provisions of the applicable subsection of 35 USC § 102, if the filing of a terminal disclaimer is required or advisable, the Parties shall first agree on terms and conditions under which the patent application subject to such terminal disclaimer and the patent or application over which such application is disclaimed shall be jointly enforced, to the extent that the Parties have not previously agreed to such terms and conditions. In the event that Roche enters into an agreement with a Third Party with respect to the further research, development or commercialization of a Product, Atea shall, upon Roche’s request, similarly enter into such agreement with such Third Party for the purposes of furthering the Parties’ objectives under this Agreement, provided that such agreement does not place any material obligation on Atea.

Each Party shall promptly provide written notice to the other Party during the Agreement Term of any (a) known infringement or suspected infringement by a Third Party of any Atea Patent Rights, Roche Patent Rights or Joint Patent Rights (an “Infringement”), or (b) known or suspected unauthorized use or misappropriation by a Third Party of any Atea Know-How, Roche Know-How or Joint Know-How (a “Misappropriation”), and shall provide the other Party with all evidence in its possession supporting such Infringement or Misappropriation.

Within [***] days after the Dominant Party provides or receives such written notice (“Decision Period”), the Dominant Party, in its sole discretion, shall decide whether or not to initiate a suit or action in the Territory regarding such infringement or unauthorized use or misappropriation and shall notify other Party of its decision in writing (“Suit Notice”). The “Dominant Party” shall be (i) Roche in the case of (A) a Misappropriation of Roche Know-How in the Atea Territory (a “US

Roche Know-How Misappropriation” or (B) an Infringement or Misappropriation in the Roche Territory, and (ii) Atea in the case of an Infringement or Misappropriation of in the Atea Territory other than a US Roche Know-How Misappropriation.

If the Dominant Party decides to bring a suit or take action, once the Dominant Party provides Suit Notice, the Dominant Party may immediately commence such suit or take such action. In the event that the Dominant Party (i) does not in writing advise the other Party within the Decision Period that the Dominant Party will commence suit or take action, or (ii) fails to commence suit or take action within a reasonable time after providing Suit Notice, the other Party shall thereafter have the right to commence suit or take action and shall provide written notice to the Dominant Party of any such suit commenced or action taken by it.

Upon written request, the Party bringing suit or taking action (“Initiating Party”) shall keep the other Party informed of the status of any such suit or action and shall provide the other Party with copies, to the extent the Initiating Party is lawfully permitted to do so, of all substantive documents or communications filed in such suit or action. The Initiating Party shall have the sole and exclusive right to select counsel for any such suit or action; provided that the other Party may engage counsel to monitor such suit or action at such other Party’s expense.

The Initiating Party shall, except as provided below, pay all expenses of the suit or action, including the Initiating Party’s attorneys’ fees and court costs. Unless otherwise agreed by the Parties, and subject to the Parties’ respective obligations under Article 16, all monies recovered upon the final judgment or settlement of any action described in this Section 14.13 shall be used as follows:

If the Initiating Party believes it is reasonably necessary or desirable to obtain an effective remedy, upon written request the other Party agrees to be joined as a party to the suit or action but shall be under no obligation to participate except to the extent that such participation is required as the result of its being a named party to the suit or action. At the Initiating Party’s written request, the other Party shall offer reasonable assistance to the Initiating Party in connection therewith at no charge to the Initiating Party except for reimbursement of reasonable out-of-pocket expenses incurred by the other Party in rendering such assistance. The other Party shall have the right to participate and be represented in any such suit or action by its own counsel at its own expense.

The Initiating Party may settle, consent judgment or otherwise voluntarily dispose of the suit or action (“Settlement”) without the written consent of the other Party but only if such Settlement can be achieved without adversely affecting the other Party or its Affiliates (including their interest in and to the Product or to any of their Patent Rights). If a Settlement could adversely affect the other Party, then the written consent of the other Party would be required, which consent shall not be unreasonably withheld.

For any patent that is not an Atea Patent Right or a Joint Patent Right, Roche, in its sole discretion, shall decide whether or not to initiate such suit or action in the Territory. Roche shall have full discretion as to how it wishes to handle such suit and may reach Settlement and retain all

damages, settlement fees or other consideration under any terms and conditions it desires and retain whatever proceeds are realized in such suit or action. Only if a Settlement could adversely affect Atea or its Affiliates (including their interest in and to the Product or to any of their Patent Rights) shall the written consent of Atea be required, which consent shall not be unreasonably withheld.

If a Third Party asserts that a Patent Right controlled by it is, or will be, infringed by the exploitation of the Product in the Territory in accordance with this Agreement, then the Party first obtaining knowledge of such claim will promptly provide the other with prompt written notice thereof and the related facts in reasonable detail.

During the Agreement Term, if a Third Party asserts that a Patent Right controlled by such Third Party is infringed, or will be infringed, by the exploitation of the Product, then the JSC will promptly discuss the matter and the appropriate course of action. If the JSC cannot agree on a course of action within [***] days following the date on which the JSC receives notice of such Third Party claim, then: (a) Atea will have the first right, but not the obligation, to defend such claim in the Atea Territory using counsel of its own choosing, and (b) Roche will have the first right, but not the obligation, to defend such claim in the Roche Territory using external counsel agreed by the Parties. If the Party having the first right does not take affirmative steps to defend such claim in the Respective Territory within [***] days (or such shorter period of time as is legally required to answer to such claim), then the other Party may defend such claim in such territory.

The Party defending such claim will (i) keep the other Party reasonably informed regarding any such assertion, including by providing the other Party with copies of all pleadings and other documents filed in any proceeding relating to such claim, (ii) consider reasonable input from the other Party during the course of the claim, and (iii) provide the other Party with the opportunity to attend any substantive meetings, hearings, or other proceedings related to such claim (together with its own counsel, at its own expense) and to review and comment on all substantive documents related to such claim prior to filing or submission of such documents. The Parties will reasonably assist each other and cooperate and share information with respect to any such claim. Each Party will bear its own costs and expenses with respect to any such claim.

Each Party is free to pursue or enter into any settlement or license agreement with any Third Party with respect to the Patent Rights that are the subject of a claim brought by a Third Party that a Patent Right controlled by such Third Party is infringed by the exploitation of the Product in the Relevant Territory without the other Party’s prior written consent provided such settlement or license agreement does not affect the other Party or its Affiliates (including their interest in and to the Product or to any of their Patent Rights). The Parties acknowledge and agree that [***].

If in either Party’s opinion a license to Third Party Patent Rights or other intellectual property rights is necessary or reasonably useful to develop, make, use or sell Products, then such Party may notify the other Party in writing of the Third Party and the applicable intellectual property rights, and the Parties will cooperate to negotiate and enter into a license or other agreement with the Third Party to obtain a license to such Third Party intellectual property rights (a “Third Party IP

License”). [***] shall have the first right to negotiate and enter into a Third Party IP License with a Third Party to obtain [***] Third Party Rights, and [***] shall have the first right to negotiate and enter into a Third Party IP License to obtain [***] Third Party Rights (the Party having the first right to negotiate and enter into any such license or other agreement being the “Primary Negotiating Party”). The Primary Negotiating Party will have the right for a reasonable period following such notice to negotiate the Third Party IP License or otherwise resolve the matter by, for example, challenging the relevant Third Party Patent Rights or conducting any oppositions, inter partes reviews or similar proceedings. If the Primary Negotiating Party is unable or unwilling to obtain such license within such reasonable period, then the other Party shall have the right to obtain such license from the Third Party or otherwise resolve the matter by, for example, challenging the relevant Third Party Patent Rights or conducting any oppositions, inter partes reviews or similar proceedings. Notwithstanding which Party negotiates and enters into a Third Party IP License pursuant to this Section 14.15, the Parties will mutually agree on the terms and conditions of any such Third Party IP License. If the Parties are unable to agree on the terms and conditions of any Third Party IP License, the matter will be escalated to the JSC.

With regard to any information or opinions disclosed pursuant to this Agreement by one Party to each other regarding intellectual property or technology owned by Third Parties, the Parties agree that they have a common legal interest in determining whether, and to what extent, Third Party intellectual property rights may affect the conduct of the development or manufacturing activities under this Agreement or Compounds or Products, and have a further common legal interest in defending against any actual or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the conduct of the development or manufacturing activities under this Agreement or Compounds or Products. Accordingly, the Parties agree that all such information and materials obtained by Atea and Roche from each other will be used solely for purposes of the Parties’ common legal interests with respect to the conduct of the Agreement. All information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable. By sharing any such information and materials, neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials. Neither Party shall have the authority to waive any privilege or immunity on behalf of the other Party without such other Party’s prior written consent, nor shall the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party. Notwithstanding the foregoing, neither Party’s attorney represents the other Party.

Notwithstanding anything herein to the contrary, should a Party receive a certification for a Product pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984 (Public Law 98-417, known as the Hatch-Waxman Act), as amended, or its equivalent in a country other than the US, then such Party shall immediately provide the other Party with a copy of such certification.

Atea shall have the sole right to bring suit, at its expense, within a [***] day period from the date of any such certification in the Atea Territory.

Roche shall have the sole right to bring suit, at its expense, within the applicable, country-specific maximum period of time from the date of any such certification in the Roche Territory.

Atea shall use Commercially Reasonable Efforts to obtain all available patent term extensions, adjustments or restorations, or supplementary protection certificates (“SPCs”, and together with patent term extensions, adjustments and restorations, “Patent Term Extensions”) for Atea Patent Rights or Joint Patent Rights with respect to the Product that Atea Handles pursuant to Section 14.8. All filings for such Patent Term Extensions shall be made by Atea (unless the Parties otherwise agree in writing); provided, that in the event that Atea elects not to file for a Patent Term Extension, Atea shall (a) promptly inform Roche of its intention not to file and (b) grant Roche the right to file for such Patent Term Extension.

Roche shall use Commercially Reasonable Efforts to obtain all available SPCs and Patent Term Extensions for Roche Patent Rights or Joint Patent Rights with respect to the Product that Roche Handles pursuant to Section 14.8. All filings for such Patent Term Extensions shall be made by Roche (unless the Parties otherwise agree in writing); provided, that in the event that Roche elects not to file for a Patent Term Extension, Roche shall (a) promptly inform Atea of its intention not to file and (b) grant Atea the right to file for such Patent Term Extension.

Each Party shall execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain such Patent Term Extensions. The Parties shall cooperate with each other in gaining patent term restorations, extensions or SPCs wherever applicable to such Atea Patent Rights, Roche Patent Rights or Joint Patent Rights.

Atea has disclosed to Roche and will immediately continue to disclose to Roche (i) the material results of all preclinical testing and human clinical testing of Products in its possession or control and (ii) all material information in its possession or control concerning side effects, injury, toxicity or sensitivity reaction and incidents or severity thereof with respect to Products, if any.

Atea has no knowledge of the existence of any patent or patent application owned by or licensed to any Third Party, in which the researching, having researched, developing, having developed, registering, having registered, using, having used, making, having made, importing, having imported, exporting, having exported, marketing, having marketed, distributing, having distributed, selling or having sold Compounds, Products and Companion Diagnostics in the Field and in the Roche Territory would infringe a valid and enforceable claim of such patent or patent application (determined as if such application were to issue with substantially the same scope of claim existing as of the Effective Date).

Atea is the sole and exclusive owner of the Atea Patent Rights. To Atea’s knowledge, no Third Parties have any right, title or interest in or to the Atea Patent Rights. Except for rights granted under this Agreement, the Atea Patent Rights are free and clear of all liens, claims, security interests and other encumbrances of any kind or nature. Atea has not granted any licenses to the

Atea Patent Rights to any Third Party for the development and commercialization of Compounds or Products in the Field in the Roche Territory (excluding rights granted to Third Parties performing activities on behalf of Atea), nor has Atea effectuated any prior transfer, sale or assignment of any part of the Atea Patent Rights.

Atea warrants that the inventors of the inventions claimed in Atea Patent Rights have transferred to Atea full ownership of the Patent Rights and Know-How licensed to Roche under this Agreement. All of Atea’s employees, officers and consultants performing activities with respect to Compounds and Products have executed agreements requiring assignment to Atea of all inventions made by such individuals during the course of and as a result of their association with Atea.

To Atea’s knowledge, Atea has the lawful right to grant Roche and its Affiliates the rights and licenses described in this Agreement.

Atea has no knowledge of information that could reasonably be deemed to render invalid or unenforceable any claims that are in any of the issued Atea Patent Rights. Atea has no knowledge of any inventorship disputes concerning any Atea Patent Rights.

Atea’s Know-How is legitimately in the possession of Atea and to Atea’s knowledge has not been misappropriated from any Third Party. Atea has taken reasonable measures to protect the confidentiality of its Know-How.

There are no claims or investigations, pending or, to Atea’s knowledge, threatened against Atea or any of its Affiliates, at law or in equity, or before or by any governmental authority (excluding ordinary course prosecution before a patent authority) relating to the matters contemplated under this Agreement or that would materially adversely affect Atea’s ability to perform its obligations hereunder.

The execution, delivery and performance of this Agreement by either Party and all instruments and documents to be delivered by either Party, hereunder: (i) are within the corporate power of such Party; (ii) have been duly authorized by all necessary or proper corporate action; (iii) are not in contravention of any provision of the certificate of formation or limited liability company agreement of such Party; (iv) to the knowledge of such Party, will not violate any law or regulation or any order or decree of any court of governmental instrumentality; (v) will not violate the terms of any indenture, mortgage, deed of trust, lease, agreement, or other instrument to which such Party is a party or by which such Party or any of its property is bound, which violation would have an adverse effect on the financial condition of such Party or on the ability of such Party to perform its obligations hereunder; and (vi) do not require any filing or registration with, or the consent or approval of, any governmental body, agency, authority or any other person, which has not been

made or obtained previously (other than Regulatory Approvals required for the sale of Products and filings with Regulatory Authorities required in connection with Products).

Neither Party nor any of its Affiliates is or will be under any obligation to any person, contractual or otherwise, that is conflicting with the terms of this Agreement or that would impede the fulfillment of such Party’s obligations hereunder.

During the Agreement Term and for a minimum period of [***] years thereafter and for an otherwise longer period as may be required by Applicable Law, each Party will procure and maintain insurance consistent with industry practice or required by Applicable Law, which may be through self-insurance. Such insurance shall insure against liability arising from this Agreement on the part of either party or any of its respective Affiliates, due to injury, disability or death of any person or persons, or property damage arising from activities performed by such Party or its Affiliates in connection with this Agreement. Any insurance proceeds received by a Party in connection with any indemnified claim shall be retained by such Party and shall not reduce any obligation of the other Party under Article 16 with respect to such claim.

Each Party represents and warrants that as of the Effective Date it and its Affiliates and its and their respective employees, in each case involved in the development of the Compounds or the Products under this Agreement, are not debarred under 21 U.S.C. §335a, disqualified under 21 C.F.R. §312.70 or §812.119, sanctioned by a Federal Health Care Program (as defined in 42 U.S.C §1320 a-7b(f)), including the federal Medicare or a state Medicaid program, or debarred, suspended, excluded or otherwise declared ineligible from any other similar federal or state agency or program in the United States or any other country. In the event a Party, any of its Affiliates or an employee of such Party or its Affiliates, in each case involved in development of the Compounds or the Products under this Agreement, receives notice of debarment, suspension, sanction, exclusion, ineligibility or disqualification under the above-referenced statutes or any other similar federal or state agency or program in the United States or any other country, such Party shall immediately notify the other Party in writing.

Each Party represents and warrants to the other Party that it, with respect to the development, manufacture and commercialization of the Compounds or the Products under this Agreement, has complied and will comply with all Applicable Laws governing bribery, money laundering, and other corrupt practices and behavior.

EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT, THE FOREGOING REPRESENTATIONS AND WARRANTIES ARE IN LIEU OF ALL OTHER REPRESENTATIONS AND WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF PRODUCTS AND FREEDOM FROM INFRINGEMENT OF THIRD PARTY RIGHTS.

Roche shall indemnify, hold harmless and defend Atea, Atea’s Affiliates and their directors, officers, employees and agents (“Atea Indemnitees”) from and against any and all losses, damages, expenses, costs of defense (including without limitation reasonable attorneys’ fees, witness fees, damages, judgments, fines and amounts paid in settlement) and any other amounts (collectively, “Losses”) resulting from Third Party claims or suits (“Third Party Claims”) arising out of or relating to (a) the breach of the Agreement by Roche, (b) the development, manufacture, commercialization, storage, transportation, handling, formulation or other exploitation of Compounds or Products by or on behalf of Roche in the Roche Territory or pursuant to a Unilateral Study conducted by Roche in the Territory (e.g. product liability claims), or (c) the negligence or willful misconduct of Roche Indemnitees, except, in each case (a), (b) and (c), to the extent such Losses are subject to indemnification by Atea pursuant to Section 16.2.

Atea shall indemnify, hold harmless and defend Roche, Roche’s Affiliates and their directors, officers, employees and agents (“Roche Indemnitees”) from and against any and all Losses resulting from Third Party Claims arising out of or relating to (a) the breach of the Agreement by Atea, (b) the development, manufacture, commercialization, storage, transportation, handling, formulation or other exploitation of Compounds or Products by or on behalf of Atea in the Atea Territory or pursuant to a Unilateral Study conducted by Atea in the Territory (e.g. product liability claims), or (c) the negligence or willful misconduct of Atea Indemnitees, except, in each case (a), (b) and (c), to the extent such Losses are subject to indemnification by Roche pursuant to Section 16.1.

In the event of a Third Party Claim against a Party entitled to indemnification under this Agreement (“Indemnified Party”), the Indemnified Party shall promptly notify the other Party (“Indemnifying Party”) in writing of the claim and the Indemnifying Party shall undertake and solely manage and control, at its sole expense, the defense of the claim and its settlement. The Indemnified Party shall cooperate with the Indemnifying Party and may, at its option and expense, be represented in any such action or proceeding by counsel of its choice. The Indemnifying Party shall not be liable for any litigation costs or expenses incurred by the Indemnified Party without the Indemnifying Party’s written consent. The Indemnifying Party shall not settle any such claim unless such settlement fully and unconditionally releases the Indemnified Party from all liability relating thereto, unless the Indemnified Party otherwise agrees in writing.

EXCEPT IN THE CASE OF A BREACH OF ARTICLE 18, AND WITHOUT LIMITING THE PARTIES' OBLIGATIONS UNDER ARTICLE 16, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION DAMAGES RESULTING FROM LOSS OF USE, LOSS OF PROFITS, INTERRUPTION OR LOSS OF BUSINESS, OR OTHER ECONOMIC LOSS) ARISING OUT OF THIS AGREEMENT OR WITH RESPECT TO A PARTY'S PERFORMANCE OR NON-PERFORMANCE HEREUNDER.

During the Agreement Term and for [***] years thereafter, a Receiving Party shall (i) treat Confidential Information provided by Disclosing Party as it would treat its own information of a similar nature, (ii) take all reasonable precautions not to disclose such Confidential Information to Third Parties, without the Disclosing Party’s prior written consent, and (iii) not use such Confidential Information other than for fulfilling its obligations under this Agreement.

Notwithstanding the obligation of non-use and non-disclosure set forth in Section 18.1, the Parties recognize the need for certain exceptions to this obligation, specifically set forth below, with respect to press releases, patent rights, publications, certain commercial considerations and for the purposes of complying with Applicable Law.

The Parties may issue a press release announcing the existence and selected key terms of this Agreement, in a form substantially similar to the template attached as Appendix 18.3.

Subject to the first sentence of this Section 18.3, during the Agreement Term, each Party may only issue press releases making reference to the other Party in connection with this Agreement, this Agreement and/or any activities or information related to this Agreement, that in each case either (i) have been approved by the other Party or (ii) are required to be issued as a matter of Applicable Law (including, for clarity, the rules of any securities exchange). Prior to issuing such press release, the issuing Party shall provide the other Party with a copy of a substantially final draft press release at least [***] (or such shorter amount of time to comply with Applicable Law, including the U.S. Securities Act of 1933 and the U.S. Securities Exchange Act of 1934, and the rules of any securities regulator, where it was not possible to provide the other Party such draft [***] in advance) prior to its intended publication for the other Party’s review. The non-issuing Party may provide the issuing Party with suggested modification to the draft press release. The issuing Party shall consider the other Party’s suggestions in good faith in issuing its press release.

To ensure communication alignment, responses (if any) to inquiries by media or other Third Parties after issuance of a permitted press release by a Party (solely or jointly with the other Party) shall consist solely of the press release language or shall follow the response guidelines that may be mutually developed by the Parties.

During the Agreement Term, the following restrictions shall apply with respect to disclosure by any Party of Confidential Information relating to the Product in any publication or presentation:

Nothing in this Agreement shall prevent either Party or its Affiliates from disclosing Confidential Information of the other Party to (i) governmental agencies [***] to secure government approval for the development, manufacture or sale of Product in the Territory, including with respect to Roche as permitted in Section 2.1, (ii) Third Parties acting on behalf of such Party, [***] for the development, manufacture or sale of Product in the Territory, as permitted under this Agreement, (iii) [***] or (iv) Third Parties to the extent reasonably necessary to market the Product in the Territory, as set forth in this Agreement. Each Party may further disclose Confidential Information of the other Party, including the terms of this Agreement, to its actual or potential sublicensees; provided that such sublicensees are subject to obligations of confidentiality and non-use with respect to such Confidential Information that are no less restrictive than the obligations of confidentiality and non-use of any Receiving Party pursuant to this Article 18.

The Receiving Party may disclose Confidential Information of the Disclosing Party to the extent that such Confidential Information is required to be disclosed by the Receiving Party to comply with Applicable Law, including the U.S. Securities Act of 1933 and the U.S. Securities Exchange Act of 1934, to comply with the rules of any securities regulator, to defend or prosecute litigation or to comply with governmental regulations or any judicial process, provided that the Receiving Party provides prior written notice of such disclosure to the Disclosing Party to the extent permitted under Applicable Law and, to the extent practicable, takes reasonable and lawful actions to minimize the degree of such disclosure.

This Agreement shall commence upon the Effective Date and continue for the Agreement Term.

A Party (“Non-Breaching Party”) shall have the right to terminate this Agreement in its entirety or on a country-by-country basis in the event the other Party (“Breaching Party”) is in breach of any of its material obligations under this Agreement. The non-Breaching Party shall provide written notice to the Breaching Party, which notice shall identify the breach and the countries in which the Non-Breaching Party intends to have this Agreement terminate. The Breaching Party shall have a period of ninety (90) days after such written notice is provided (“Peremptory Notice Period”) to cure such breach. If the Breaching Party has a dispute as to whether such breach occurred or has been cured, it will so notify the Non-Breaching Party, and the expiration of the Peremptory Notice Period shall be tolled until such dispute is resolved pursuant to Section 21.2. Upon a determination of breach or failure to cure, the Breaching Party may have the remainder of the Peremptory Notice Period to cure such breach. If such breach is not cured within the Peremptory Notice Period, then absent withdrawal of the Non-Breaching Party’s request for termination, this Agreement shall terminate in its entirety or such identified countries effective as of the expiration of the Peremptory Notice Period.

A Party shall have the right to terminate this Agreement, if the other Party experiences an Insolvency Event; provided, however, in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the Party that incurs the Insolvency Event consents to the involuntary bankruptcy or such proceeding is not dismissed within ninety (90) days after the filing thereof.

Roche shall have the right to terminate this Agreement at any time as a whole or on a Product-by-Product or country-by-country basis upon either (i) three (3) months prior written notice if such notice is provided before First Commercial Sale of the first Product under this Agreement, provided that at the time when Roche sends the termination notice under this Section 19.2.3(i) the Post-Exposure Prophylaxis study as described in the Global Development Plan in Appendix 1.47 is not ongoing, but if Roche sends its termination notice under this Section 19.2.3(i) during the time when the Post-Exposure Prophylaxis study as described in the Global Development Plan in Appendix 1.47 is ongoing (“ongoing” shall mean, for the purposes of this Section, that the first patient has been dosed and the last patient has not yet been dosed in such study), then the earlier of the end of such study (but not earlier than three (3) months after the time Roche sends the termination notice), or six (6) months after such termination notice is sent; or (ii) nine (9) months prior written notice if such notice is provided on or after the First Commercial Sale of the first Product under this Agreement. The effective date of termination under this Section 19.2.3 shall be the date three (3) months (as adjusted in accordance with subsection (i) above), or nine (9) months, as the case may be, after Roche provides such written notice to Atea.

Upon any termination by Atea for breach by Roche or by Roche without a cause, the rights and licenses granted by Atea to Roche under this Agreement shall terminate in their entirety or on a country-by-country and Product-by-Product basis, as applicable, on the effective date of termination.

If Atea desires to continue development or commercialization of Product(s), Atea shall give a Continuation Election Notice to Roche within [***] days of Atea’s notice of termination for breach by Roche or Atea’s receipt of Roche’s notice of termination without cause. If Roche receives such a timely Continuation Election Notice, and to the extent reasonably requested by Atea:

Upon any termination by Roche for breach by Atea or Atea’s Insolvency Event, the rights and licenses granted by one Party to the other Party under this Agreement shall terminate in their entirety or on a country-by-country and a Product-by-Product basis, as applicable, on the effective date of termination.

If Atea does not provide a timely Continuation Election Notice, then Roche (a) shall have the right to cancel all ongoing obligations and (b) shall complete all non-cancellable obligations at its own expense, except in each case to the extent inconsistent with protecting patient safety.

If Atea provides such timely Continuation Election Notice, then from the date of notice of termination until the effective date of termination, Roche shall continue activities, including preparatory activities, ongoing as of the date of notice of termination unless otherwise agreed by the Parties, with expenses thereof incurred prior to the effective date of termination to be shared equally (50/50) by the Parties consistent with Section 6.2. Such obligation to continue activities may include without limitation continuing to perform under any then-effective contracts applicable to the development, manufacture or commercialization of Compound or Product until completion all of such relevant activities, unless Atea otherwise agrees in writing or requests in writing, subject to Atea’s obligations to bear any portion thereof or to pay for any supply of Product as set forth in this Agreement. However, Roche shall not be obliged to initiate any new activities not ongoing at the date of notice of termination.

Except in case Roche terminates for Atea’s uncured material breach (Section 19.2.1) or for Atea’s insolvency (Section 19.2.2), Roche shall also be solely responsible for any reasonable cancellation or early termination fees that become due under vendor contracts by reason of such termination, if such contracts are not transferred to Atea as provided in Section 19.3.1(b).

After the effective date of termination, Roche shall have no obligation to perform or complete any activities or to make any payments for performing or completing any activities under this Agreement, except as expressly stated herein.

In the case of termination by Atea according to Section 19.2.1 or 19.2.2 or by Roche under Section 19.2.3, upon the request of Atea, Roche shall transfer all of its existing and available clinical supplies and commercial supplies of Products to Atea at [***]. If a Product is marketed in any country of the Territory on the date of the notice of termination of this Agreement, upon the request of Atea, Roche shall manufacture and supply reasonable amounts of such Product to Atea under a manufacturing transfer and transition plan for a period that shall not exceed [***] months from the effective date of the termination of this Agreement at a price to be agreed by the Parties in good faith, but in no event exceeding (i) [***], or (ii) [***]. Atea shall use Commercially Reasonable Efforts to take over the manufacturing as soon as possible after the effective date of termination.

Unless otherwise agreed by the Parties, the termination of this Agreement shall cause the automatic termination of all ancillary agreements related hereto, including but not limited to the Co-Promotion Agreement(s) or, subject to Section 19.3.4.2, Supply Agreement(s), if any, except to the extent such ancillary agreements are related to or necessary for the Parties’ activities under this Section 19.3, in which case the relevant agreement(s) shall terminate upon completion of the relevant activity(ies).

For purposes of clarity, irrespective of anything to the contrary in this Agreement:

Termination of this Agreement by a Party, for any reason, shall not release either Party from any obligation to pay royalties or make any payments to the other Party that are payable prior to the effective date of termination. Termination of this Agreement by a Party, for any reason, will release each Party from any obligation to pay royalties or make any payments to the other Party that would otherwise become payable on or after the effective date of termination.

Atea Pharmaceuticals Announces Strategic Collaboration with Roche to Develop and Distribute AT-527 for Patients with COVID-19

Roche Obtains Exclusive Right to Develop and Distribute AT-527 Outside the United States

BOSTON, Mass., October 22, 2020 – Atea Pharmaceuticals, Inc., a clinical stage biopharmaceutical company focused on discovering, developing and commercializing antiviral therapeutics to improve the lives of patients suffering from life-threatening viral infections, today announces that the company has entered into an agreement with Roche (SIX: RO, ROG; OTCQX: RHHBY) for the exclusive rights to research, develop and distribute AT-527 as an oral antiviral treatment for COVID-19 in territories outside of the United States. Under the terms of the agreement, Atea will receive an upfront payment of $350 million in cash from Roche with the potential for future milestone payments and royalties.

“Roche shares our passion for delivering innovative new medicines to address great unmet medical needs. The COVID-19 pandemic has highlighted the urgent need for a novel, oral antiviral to treat this highly infectious and often deadly virus,” said Jean-Pierre Sommadossi, Ph.D., Chief Executive Officer and Founder of Atea Pharmaceuticals. “This collaboration with Roche enhances Atea’s efforts and underscores the potential for AT-527 to effectively address the COVID-19 crisis on a global scale. AT-527 is expected to be ideally suited to combat COVID-19 as it inhibits viral replication by interfering with viral RNA polymerase, a key component in the replication machinery of RNA viruses. Importantly, the manufacturing process for our small molecule direct-acting antiviral allows us to produce AT-527 quickly and at scale.”

"The ongoing complexities of COVID-19 require multiple lines of defence. By joining forces with Atea, we hope to offer an additional treatment option for hospitalised and non-hospitalised COVID-19 patients, and provide important relief for hospital infrastructures during a global pandemic." said Bill Anderson, Chief Executive Officer of Roche Pharmaceuticals. "In jointly developing and manufacturing AT-527 at scale, we seek to make this treatment option available to as many people around the world as we possibly can."

AT-527 is an orally administered, direct-acting antiviral agent derived from Atea’s purine nucleotide prodrug platform. At-527 is currently under evaluation as a treatment for patients with COVID-19. AT-527 is designed to inhibit viral replication by interfering with viral RNA

polymerase, a key component in the replication machinery of RNA viruses, such as positive single-stranded human flaviviruses and human coronaviruses. AT-527 is currently in a global Phase 2 clinical study for hospitalized patients with moderate COVID-19 and has plans to initiate a global, registrational Phase 3 clinical trial in outpatients in the first half of 2021. Additionally, Atea is planning to study in a Phase 3 clinical trial the use of AT-527 in the post-exposure prophylaxis setting.

Evercore served as exclusive financial advisor to Atea in connection with this transaction.

Roche announces collaboration with Atea Pharmaceuticals to develop a potential oral treatment for COVID-19 patients

Basel, xx October 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) and Atea Pharmaceuticals, Inc. announced today that they are joining forces in the fight against COVID-19 to develop, manufacture and distribute AT-527, Atea’s investigational oral direct-acting antiviral, to people around the globe. AT-527 acts by blocking the viral RNA polymerase enzyme needed for viral replication, and is currently being studied in a Phase 2 clinical trial for hospitalised patients with moderate COVID-19. A Phase 3 clinical trial, expected to start in Q1 2021, will explore the potential use in patients outside of the hospital setting. In addition, AT-527 may be developed for post-exposure prophylactic settings.

AT-527, while being a potential oral treatment option for hospitalised patients, also holds the potential to be the first oral treatment option for COVID-19 patients that are not hospitalised. Additionally, the manufacturing process of small-molecule DAAs allows the ability to produce large quantities of a much needed treatment. If successful, AT-527 could help treat patients early, reduce the progression of the infection, and contribute to decreasing the overall burden on health systems.

The collaboration aims to accelerate the clinical development and manufacturing of AT-527, to investigate its safety and efficacy, and to provide this potential treatment option to patients around the world as quickly as possible. If AT-527 proves safe and effective in clinical trials and regulatory approvals are granted, Atea will be responsible for distributing this treatment option in the U.S, with the option to request Genentech’s support, and Roche will be responsible for distribution outside the United States.

"The ongoing complexities of COVID-19 require multiple lines of defence. By joining forces with Atea, we hope to offer an additional treatment option for hospitalised and non-hospitalised COVID-19 patients, and to ease the burden on hospitals during a global pandemic." said Bill Anderson, Chief Executive Officer of Roche Pharmaceuticals. "In jointly developing and manufacturing AT-527 at scale, we seek to make this treatment option available to as many people around the world as we possibly can."

“Roche shares our passion for delivering innovative new medicines to address great unmet medical needs. The COVID-19 pandemic has highlighted the urgent need for a novel, oral antiviral to treat this highly infectious and often deadly virus,” said Jean-Pierre Sommadossi, Ph.D., Chief Executive Officer and Founder of Atea Pharmaceuticals. “AT-527 is expected to be ideally suited to combat COVID-19 as it inhibits viral replication by interfering with viral RNA polymerase, a key component in the replication machinery of RNA viruses. Importantly, the manufacturing process for our small molecule direct-acting antiviral allows us to produce AT-527 quickly and at scale.”

AT-527 is an investigational, oral, purine nucleotide prodrug, which has demonstrated in vitro and in vivo antiviral activity against several enveloped single-stranded RNA viruses, including human flaviviruses and coronaviruses. This highly selective purine nucleotide prodrug was designed to uniquely inhibit viral RNA dependent RNA polymerase, an enzyme that is essential for the replication of RNA viruses. Antiviral activity and safety of AT-527 has been demonstrated in Phase 2 clinical studies of hepatitis C patients, and in preclinical in-vitro assays with SARS-CoV2 virus. AT-527 is not yet licensed or approved for any indication in the United States or any other country.

As a leading healthcare company we are doing all we can to support countries in minimising the impact of COVID-19. We have developed a growing number of diagnostic solutions that help to detect and diagnose the infection in patients, as well as providing digital support to healthcare systems, and we continue to identify, develop and support potential therapies which can play a role in treating the disease.

We understand the impact of COVID-19 goes beyond those who contract it, which is why we are working with healthcare providers, laboratories, authorities and organisations to help make sure that patients continue to receive the tests, treatment and care they need during these challenging times. As we learn from the pandemic, we are partnering with governments and others to make healthcare stronger and more sustainable in the future.

Reliable, high-quality testing is essential to help healthcare systems overcome this pandemic. Our portfolio includes:

Roche is committed to improving the treatment of COVID-19. We are actively involved in understanding the potential of our existing portfolio and are exploring the potential of our investigational molecules.

In August, we announced a partnership with Regeneron to develop, manufacture, and increase global supply of their investigational antibody combination for COVID-19 if it proves safe and effective in clinical trials and regulatory approvals are granted.

At the beginning of the pandemic, on 19 March, we announced the initiation of COVACTA - a global Phase III randomised, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of intravenous Actemra©/RoActemra© (tocilizumab) plus standard of care in hospitalised adult patients with severe COVID-19 pneumonia compared to placebo plus standard of care. On 29 July we announced that COVACTA did not meet its primary endpoint of improved clinical status in patients with COVID-19 associated pneumonia or the key secondary endpoint of reduced mortality.

Separately, we have studied Actemra©/RoActemra© in the EMPACTA study in COVID-19 associated hospitalised pneumonia in patients that are often underrepresented in clinical trials. On 18 September we announced that the phase III EMPACTA study showed Actemra/RoActemra plus standard of care reduced the likelihood of progression to mechanical ventilation or death in hospitalised patients with COVID-19 associated pneumonia compared to placebo plus standard of care. However, there was no statistical difference in mortality between patients who received Actemra/RoActemra or placebo

Actemra©/RoActemra© is also being studied in combination with the investigational antiviral remdesivir in hospitalised patients with severe COVID-19 pneumonia in the REMDACTA trial in partnership with Gilead, announced 28 May. Actemra©/RoActemra© is not approved by any health authority for use in COVID-19 pneumonia. Roche has further initiated an internal early research programme focused on the development of medicines for COVID-19 and is engaged in multiple research collaborations.

In these exceptional times, Roche stands together with governments, healthcare providers and all those working to overcome the pandemic.
