(i) In the event that a Party (the “Paying Party”) does not withhold taxes from a payment due to the other Party (the “Recipient Party”) under this Agreement, and a governmental authority proposes to impose a liability in respect to withholding taxes in connection with such payment against the Paying Party (together with any penalties and interest imposed in connection therewith, a “Later Imposed Withholding”) the Paying Party shall promptly notify the Recipient Party of such proposal, forward any information received and shall cooperate with the Recipient Party in evaluating any such claim. If the Recipient Party chooses to contest any such claim, it shall control any such contest at its own expense. The Paying Party shall reasonably cooperate with any such contest, including facilitating the Recipient Party’s control thereof (e.g., by executing powers of attorney) and the Recipient Party shall reimburse the Paying Party for any reasonable out-of-pocket costs incurred in connection with such cooperation.

(ii) Upon either (i) a governmental authority successfully assessing a deficiency for any Later Imposed Withholding under a final determination in respect of such tax which, under applicable law, is not subject to further review, appeal or modification due to through proceedings or otherwise (including as a result of the expiration of a statute of limitations or period for the filing of claims for refunds, amended Tax Returns or appeals from adverse determinations), including a “determination” as defined in Section 1313(a) of the Code or analogous provisions of state, local or non-U.S. law, or (ii) the Recipient Party electing to not contest (or continue to contest) a proposed liability, the Recipient Party will indemnify the Paying Party for such Later Imposed Withholding.

(iii) At the Paying Party’s election, (i) the Paying Party may offset the amount of such Later Imposed Withholding indemnifiable pursuant to Section 9.4(b)(ii) from future payments due to the Recipient Party under this Agreement, or (ii) the Recipient Party shall pay the amount of such Later Imposed Withholding indemnifiable pursuant to Section 9.4(b)(ii) to the Paying Party promptly upon request. Promptly following the Paying Party withholding any Later Imposed Withholding or the Recipient Party remitting any Later Imposed Withholding to the Paying Party, the Paying Party will (A) pay to the relevant governmental authority the amount of such Later Imposed Withholding; and (B) provide evidence of such payment to the Recipient Party on a reasonable and timely basis. In the event that any Later Imposed Withholding is subsequently reduced, the Parties shall ensure that the benefit of such reduction is paid over to the Recipient Party.

(c) VAT. All payments or other consideration payable under this Agreement are exclusive of VAT. If and to the extent VAT (i) is properly chargeable in accordance with applicable laws in respect of, or as a result of, any supplies of goods or services, or sales rendered under this Agreement and (ii) is to be paid to the competent tax authorities by the Party making such supply of goods or services, or sales, the receiving Party shall pay, in addition to the payment (or the provision of other consideration for such supply or sales), an amount equal to such VAT at the applicable rate to the providing Party upon receipt of a valid VAT invoice (or, if later, on the due date for payment (or the provision of such other consideration) for such supply or sale). The Parties shall issue invoices for all amounts payable or other consideration provided under this Agreement consistent with applicable VAT laws and regulations and irrespective of whether the sums or other consideration may be netted for settlement purposes. Each Party shall provide such information as is reasonably requested by the other Party to enable the recovery, as permitted by applicable laws, of any VAT charged in respect of any supplies of goods or services, or sales, rendered under this Agreement, such recovery being for the benefit of the Party bearing the economic cost of such VAT under this Section 9.4(c). Notwithstanding the foregoing, if as a result of any assignment or sublicense by the Party providing the supply or service, any change in such providing Party’s tax residency, any change in the entity that provides the supply or service, or any failure on the part of such providing Party to comply with applicable law (other than any failure

resulting from reliance on any certification or other information provided by the Party receiving the supply or service with respect to the amount of applicable VAT) with respect to VAT (including filing or record retention requirements), VAT is imposed that would not otherwise have been imposed (“Incremental VAT”), then, if and to the extent such Incremental VAT cannot be offset or recovered by means of an input VAT deduction by the Party receiving the supply or service, the Party providing the supply or service shall be solely responsible for the amount of such Incremental VAT and shall indemnify the Party receiving the supply or service so that such receiving Party is left in the same after-Tax position it would have been in had there been no such imposition of Incremental VAT.

(d) Where under the terms of this Agreement, one Party is liable to indemnify or reimburse another person in respect of any costs, charges or expenses, the payment shall only include an amount equal to any VAT thereon not recoverable by the other Party (or the principal or representative member of any VAT group of which it forms part), subject to that Party (or representative member) taking all reasonable steps to recover such amount of VAT as may be practicable.

(e) Foreign Derived Intangible Income. Affimed shall use Commercially Reasonable Efforts to provide, and to cause its Affiliates, subcontractors, sublicenses, customers, and applicable Third Parties to provide, any information and documentation reasonably requested by Artiva and reasonably available to Affimed to obtain the benefits of Section 250 of the Internal Revenue Code of 1986, as amended and the applicable Treasury Regulations, with Artiva reimbursing Affimed for all out-of-pocket costs.

9.5 Interest. If any payment due to either Party under this Agreement is not paid when due, then such paying Party shall pay interest thereon. All interest shall accrue and be calculated on a daily basis (both before and after any judgment) at a rate per annum equal to [***] above the then current “prime rate” in effect published in The Wall Street Journal (U.S., Eastern Edition), but in no event in excess of the maximum rate permissible under applicable law, for the period from the due date for payment until the date of actual payment.

9.6 Currency; Exchange Rate. All payments under this Agreement shall be payable in US Dollars. When conversion of payments from any foreign currency is required in connection with the payment of any payment obligations under this Agreement, such conversion shall be made by each Party according to the conversion mechanism it generally applies under its Accounting Standards.

9.7 Financial Records; Audit.

(a) Record-Keeping Obligations. Each Party shall, and shall cause its Affiliates and (using reasonable efforts) its licensees to, keep and maintain complete and accurate books and records pertaining to: (i) all costs incurred by such Party in connection with the performance of Confirmatory Combination Therapy Trial Activities in sufficient detail to permit the other Party to confirm the basis and accuracy of the costs incurred by such Party under this Agreement; (ii) inputs necessary to calculate the Agreement Payment in accordance with Section 9.2(c); (iii) with respect to Artiva only, all In-Scope Artiva Adjusted Revenue, and (iv) with respect to Affimed only, all In-Scope Affimed Adjusted Revenue. Such books and records shall be retained by such Party (and its Affiliates and licensees) until the later of: (A) [***] after the end of the period to which such books and records pertain; or (B) the expiration of the applicable tax statute of limitations (including any extensions thereof), or for such longer period as may be required by Applicable Law.

(b) Audit. At the request of the other Party, each Party shall, and shall cause its Affiliates and (using reasonable efforts) its (sub-)licensees to, permit an independent public accounting firm of internationally recognized standing designated by the other Party and reasonably acceptable to the audited Party, at reasonable times during normal business hours and upon reasonable notice, to audit the books and records maintained pursuant to Section 9.7(a) to ensure the accuracy of all reports, invoices and payments made hereunder. [***]. The accounting firm shall disclose to the auditing Party only whether the audited information is correct or incorrect and the specific details concerning any discrepancies. Except as provided below, the cost of any audit conducted pursuant to this Section 9.7(b) shall be borne by the auditing Party, unless the audit reveals a variance of more than [***] from the reported or invoiced amounts, in which case, the audited Party shall bear the full cost of the audit. If such audit concludes that (A) additional amounts were owed by the audited Party, the audited Party shall pay the additional amounts, plus interest calculated in accordance with Section 9.5 or (B) excess payments were made by the audited Party, the auditing Party shall reimburse the audited Party for any such excess payments, in each case of clause (A) or (B), within [***] of the accounting firm’s audit report.

Each Party hereby assigns to the other Party such interest in such Joint Collaboration Inventions and Joint Collaboration Patents as necessary to vest joint ownership in the Parties. Except as expressly provided under this Agreement, unless otherwise agreed by the Parties on a commercially reasonable royalty or other compensation for the practice of such Joint Collaboration Inventions or any Joint Collaboration Patents, neither Party shall have any rights to license, assign or exploit its interests in any Joint Collaboration Invention or Joint Collaboration Patent anywhere in the world. [***].

(c) Non-Program Inventions. The Parties acknowledge and agree that each of the Parties Controls and may gain Control over certain Know-How and other intellectual property rights with respect to NK Cell technology and/or Innate Cell Engager Technology through activities outside the scope of the collaboration hereunder and independent of the Parties’ performance hereunder or the Combination Therapy Trials or activities under the Development Plan, which are in each case not provided by the Controlling Party nor used for the conduct of the Combination Therapy Trial or activities under the Development Plan (the “Non-Program Inventions”). The Party that Controls such Non-Program Inventions shall retain all rights, title, and interests in and to such Non-Program Inventions, and such Non-Program Inventions shall not be subject to Section 10.1(b).

10.2 Prosecution and Maintenance.

(a) Product Patents. Artiva shall have the sole right, at its sole expense, to Prosecute and Maintain, defend and enforce any and all Patents that Cover an Artiva Product Invention (and not an Affimed Invention or Joint Collaboration Invention) (“Artiva Product Patents”).

(b) Coordination; Recovery. The Parties will promptly meet, discuss and agree, in light of the circumstances of such Infringement, which Party should take the lead or whether the Parties should jointly lead in initiating legal action to enforce any Joint Patents against infringement, and to protect any Know-How within Joint Technology from misappropriation, or to defend any declaratory judgment action relating thereto. If the Parties mutually agree to initiate such legal proceeding, each Party shall be responsible for [***] of the reasonable, verifiable, and out-of-pocket costs incurred in connection with such action. [***].

(c) Allocation of Recoveries. Any damages recovered from a Third Party in an Infringement action shall be first allocated to reimburse the Parties for their costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses), [***].

10.4 Infringement of Third Party Rights.

(a) Notice. If the Development or Promotion of the Combination Therapy or the conduct of any Combination Therapy Trial becomes the subject of a claim of infringement of a Patent, copyright, or other proprietary right by a Third Party, the Party first having notice of the claim shall promptly notify the other Party and, without regard to which Party is charged with said infringement and the venue of such claim, the Parties shall promptly confer to discuss the claim and the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such potential dispute.

(b) Coordination; Recovery. If an infringement claim described in Section 10.4(a) is brought against one or both Parties, except as provided in the last sentence of this Section 10.4(b), the Parties shall defend such claim jointly, unless they agree otherwise in writing. [***]. If the charged Party does not commence actions to defend such claim within thirty (30) days after being so charged, then the other Party shall have the right, but not the obligation, to defend such claim. The non-defending Party shall reasonably cooperate with the Party conducting the defense of the claim and shall have the right to participate with separate counsel at its own expense, and the defending Party shall consider in good faith the non-defending Party’s comments and suggestions on strategy for defending such action. The Party defending the claim shall bear the costs of the defense of any such claim and shall have sole rights to any recovery. No Party shall enter into any settlement concerning activities under this Agreement or any Combination Therapy that affects the other Party’s rights under this Agreement or imposes any obligations on the other Party, including any admissions of wrongdoing on behalf of the other Party, without such other Party’s prior written consent, such consent not to be unreasonably withheld or delayed. Notwithstanding the foregoing, if a claim of infringement described in Section 10.4(a) is attributable solely to one Party’s Development, Manufacture or Commercialization of its Product, such Party shall have the sole right and obligation, to defend and settle the disposition of such claim, at its sole expense, in a manner not to materially adversely impact the other Party’s rights under this Agreement.

Affimed shall defend, indemnify and hold harmless Artiva, its Affiliates, and its and their employees, directors, subcontractors and agents (collectively, the “Artiva Indemnitees”) from and against any liabilities, damages, settlements, penalties, fines, reasonable costs and expenses (including, reasonable attorneys’ fees and other expenses of litigation) (collectively, “Losses”) resulting from Third Party suits, claims, actions, allegations and demands (each, a “Third Party Claim”) against an Artiva Indemnitee to the extent that they arise or result from: (a) the negligence or willful misconduct by any Affimed Indemnitee in connection with this Agreement, (b) a breach by Affimed of any of its representations, warranties, covenants or other obligations of Affimed under this Agreement, (c) any Later Imposed Withholding (subject to Section 9.4(b)), (d) any injury to a subject in the Combination Therapy Trial to the extent attributable to the Affimed Product, (e) any injury to a customer or end-user of Combination Therapy to the extent attributable to the Affimed Product or (f) the use by Affimed, its Affiliates, contractors or licensees of Combination Therapy Clinical Data, Affimed Inventions, or Joint Technology (including Joint Patents); but excluding, in each case (of (a) through (f)), any such Losses to the extent arising or resulting from a cause or event for which Artiva is obligated to indemnify the Affimed Indemnitees pursuant to Section 14.2.

14.2 Indemnification by Artiva. Artiva shall defend, indemnify and hold harmless Affimed, its Affiliates, and its and their employees, directors, subcontractors and agents (collectively, the “Affimed Indemnitees”) from and against any Losses resulting from Third Party Claims against an Affimed Indemnitee to the extent that they arise or result from: (a) the negligence or willful misconduct by any Artiva Indemnitee in connection with this Agreement, (b) a breach by Artiva of any of its representations, warranties, covenants or other obligations of Artiva under this Agreement, (c) any Later Imposed Withholding (subject to Section 9.4(b)) (d) any injury to a subject in the Combination Therapy Trial to the extent attributable to the Artiva Product, (e) any injury to a customer or end-user of Combination Therapy to the extent attributable to the Artiva Product or (f) the use by Artiva, its Affiliates, contractors or licensees of Combination Therapy Clinical Data, Artiva Product Inventions, or Joint Technology (including Joint Patents); but excluding, in each case (of (a) through (f)), any such Losses to the extent arising or resulting from a cause or event for which Affimed is obligated to indemnify the Artiva Indemnitees pursuant to Section 14.1.

14.3 Procedure. Each Party’s indemnification obligations under Section 14.1 and Section 14.2 are conditioned upon the Party seeking indemnification (the “Indemnitee”) delivering a written notice to the other Party (the “Indemnitor”) of any applicable Third Party Claim subject to indemnification hereunder promptly after the Indemnitee becomes aware of such Third Party Claim. The Indemnitor will have no indemnification obligations hereunder to the extent materially prejudiced by any delay by the Indemnitee in providing such notice. The Indemnitor will have the sole right to defend or settle (subject to the remainder of this Section 14.3) any Third Party Claim (using counsel reasonably satisfactory to the Indemnitee). The Indemnitee will cooperate fully with Indemnitor in connection therewith, at the Indemnitor’s expense. The Indemnitee may participate in (but not control) the defense thereof at its sole cost and expense. The Indemnitor shall keep the Indemnitee advised of the status of the Third Party Claim and the defense thereof and shall reasonably consider recommendations made by the Indemnitee with respect thereto. The Indemnitee shall not agree to any settlement of any Third Party Claim without the prior written consent of the Indemnitee, which shall not be unreasonably withheld, delayed or conditioned. The Indemnitor shall not agree to any settlement of any Third Party Claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnitee from all liability with respect thereto or that imposes any liability or obligation on the Indemnitee without the prior written consent of the Indemnitee, which shall not be unreasonably withheld, delayed or conditioned.

14.4 Limitation of Liability. EXCEPT WITH RESPECT TO (a) CLAIMS INDEMNIFIABLE UNDER SECTION 14.1 AND SECTION 14.2, (b) BREACH OF ARTICLE 11 OR (c) INSTANCES OF FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, CONSEQUENTIAL, INDIRECT, OR INCIDENTAL DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT, INCLUDING LOSS OF PROFITS OR ANTICIPATED SALES, HOWEVER CAUSED, ON ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

14.5 Insurance. As long as any Combination Therapy is being clinically tested in human subjects, each Party shall place and maintain public and general liability insurance with a limit of [***]. There will be separate insurance coverage for Clinical Trials on a so-called non-fault basis. Such policy will be placed for the entire duration of any Combination Therapy Trial until its termination. Thereafter there will be an extended reporting period of at least five (5) years, which will allow the study subject to make a claim directly with the respective insurer. The study subject only has to proof a causal relationship between the study and the bodily suffering rather than any kind of negligence of any of the involved parties. Upon start of Commercialization, the Parties agree to extend the liability coverage and place products liability insurance with an appropriate limit or what is legally required. Such insurance does not create a limit of either Party’s liability with respect to its indemnification obligations under this Article 14. Each Party shall provide the other Party with a certificate of insurance evidencing such Party’s compliance with this Section 14.5 upon request. Each Party’s liability policy shall include the other Party as an additional insured. Each Party shall provide the other with a prior written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance which materially adversely affects the rights of the other Party hereunder. All required insurance policies of each Party must have a minimum “A-” AM Bests rating.

15. TERM AND TERMINATION.

15.1 Term. The term of this Agreement shall commence on the Effective Date and shall continue in full force and effect until the expiration of the last Agreement Payment Term in the Territory, unless terminated earlier by either Party pursuant to this Article 15 or by written agreement of the Parties (“Term”).

15.2 Termination for Material Breach. Either Party may terminate this Agreement if the other Party commits a breach of its material obligation under this Agreement, and such material breach is not cured by the breaching Party within [***] after the breaching Party’s receipt of written notice thereof from the non-breaching Party.

15.3 Termination for Insolvency. If, at any time during the Term, (a) a case is commenced by or against either Party under Title 11, United States Code, as amended, or analogous provisions of Applicable Law outside the United States (the “Bankruptcy Code”) and, in the event of an involuntary case under the Bankruptcy Code, such case is not dismissed within [***] after the commencement thereof, (b) either Party files for or is subject to the institution of bankruptcy, liquidation or receivership proceedings (other than a case under the Bankruptcy Code), (c) either Party assigns all or a substantial portion of its assets for the benefit of creditors, (d) a receiver or custodian is appointed for either Party’s business, or (e) a substantial portion of either Party’s business is subject to attachment or similar process (each of ((a) through (e)), a “Bankruptcy Event”); then, in any case of a Bankruptcy Event, the other Party may terminate this Agreement immediately upon written notice to the extent permitted under Applicable Law. All rights and licenses granted under or pursuant to this Agreement by each Party to the other Party, as applicable, are and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Article 101(35A) of the Bankruptcy Code. The Parties agree that each Party, as a licensee of such intellectual property rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a Party under the Bankruptcy Code or analogous provisions of Applicable Law outside the United States, the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property rights licensed to such Party under this Agreement and all embodiments of such intellectual property rights, which, if not already in such Party’s possession, will be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon such Party’s written request therefor, unless the Party in the bankruptcy proceeding elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under clause (i), following the rejection of this Agreement in the bankruptcy proceeding, upon written request therefor by the other Party.

15.4 Termination for Failure to Meet Specified Endpoints. If the Clinical Trial involving the Artiva Product [***] fails to (i) meet safety or tolerability endpoints or (ii) pass a futility assessment, [***], Affimed may terminate this Agreement upon [***] prior written notice to Artiva. [***].

15.5 Effects of Termination.

(a) Termination of Licenses. Upon any termination of this Agreement, the licenses granted by a Party to the other Party under Section 4.1 shall terminate as of the effective date of such termination.

The terminating Party shall submit to the other Party, and the Parties shall discuss and agree, a proposed wind-down, setting forth the tasks reasonably necessary or required in connection with the orderly termination of any ongoing Combination Therapy Clinical Trials and the proper plan for managing the patients enrolled in such trials, including actions reasonably necessary to safely close out such trials, or required by Applicable Laws.

(d) Survival. Any expiration or termination of this Agreement for any reason shall not release either Party of any obligation or liability which, at the time of such expiration or termination, has already accrued to such Party or which is attributable to a period prior to such expiration or termination. Without limiting the generality of the foregoing, the following provisions shall survive any termination or expiration of this Agreement: Article 10, Article 11, Article 12, Article 14, Article 17 and Article 18; and (ii) Section 3.1(b), Section 3.1(c), Section 4.2, Section 5.11, Sections 9.3 to 9.7 and Section 15.5.

The United Nations Convention on Contracts for the International Sale of Goods shall not apply to the transactions contemplated by this Agreement.

18.2 Assignment. Neither Party may assign or otherwise transfer, in whole or in part, this Agreement without the prior written consent of the other Party, such approval not to be unreasonably withheld or delayed. Notwithstanding the foregoing, either Party may assign this Agreement, in whole or in part, without the other Party’s prior written consent, to (a) an Affiliate or (b) to a successor in interest by way of merger, consolidation or sale of all or substantially all of the assets of such Party to which this Agreement relates.

18.4 Force Majeure. Neither Party shall be liable to the other Party for failure or delay in the performance of any of its obligations under this Agreement for the time and to the extent such failure or delay is caused by earthquake, riot, civil commotion, war, terrorist acts, strike, flood, or governmental acts or restriction, or other cause that is beyond the reasonable control of the affected Party, and occurring without the affected Party’s fault or negligence. The Party affected by such force majeure shall provide the other Party with full particulars thereof as soon as it becomes aware of the same (including its best estimate of the likely extent and duration of the interference with its activities), and shall use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of its obligations as soon as practicable.

Exhibit 9.2(c)

Baseball Arbitration

If the Parties cannot agree, following escalation to the Executive Officers, on the Agreement Payment pursuant to Section 9.2(c) (such dispute, an “Expert Matter”), at the request of either Party by written notice to the other Party, such Expert Matter will be resolved through binding “baseball” arbitration pursuant to this Exhibit 9.2(c) rather than pursuant to the procedures under Section 17.2. If the Expert Matter is not resolved within [***] after referral to the Parties’ Executive Officers, then either Party may send the other Party a written notice requesting to resolve the Expert Matter by using an independent investment banker who shall have no less than ten (10) years of experience in the biotechnology or pharmaceutical industry and relevant expertise and experience with respect to the Expert Matter (“Expert”) and shall be selected by mutual agreement of the Parties. If the Parties are unable to agree upon an Expert within [***] after a Party gives the written notice requesting expert resolution, then each Party will have [***] to choose a single independent expert meeting the Expert criteria, and the Parties shall instruct such experts to use best efforts to mutually select, within [***] following the selection of the second of such experts, an independent third expert who meets such criteria to be the Expert. Within [***] after appointment of the Expert, each Party shall submit to the Expert, with a copy to the other Party, one (1) proposal for resolving the applicable Expert Matter, including the proposed Agreement Payment and a reasonably detailed analysis of the model prepared by such Party taking into account the factors described in Section 9.2(c) to determine the proposed Agreement Payment. The Expert will be instructed to select one Party’s proposal no later than [***] following the receipt of both Parties’ proposals and to select the proposal that he or she determines is the most commercially reasonable under the circumstances and best gives effect to the intent of the Parties to effect the Agreed Value under this Agreement. The Expert shall select only one (1) of the proposals submitted by the Parties (without making any changes to such proposal) and shall render such proposal as the Expert’s final decision. Notwithstanding anything to the contrary in this Agreement, the Expert shall not have the authority to render any decision other than selecting one (1) proposal submitted by a Party pursuant to this Exhibit 9.2(c). The Expert’s decision shall be final and binding on the Parties. The out-of-pocket costs of the Expert in making the determination pursuant to this Exhibit 9.2(c) shall be shared equally by the Parties, regardless of the outcome of the determination. All activities undertaken by the Expert will be conducted subject to obligations of confidentiality no less restrictive than those set forth in Article 11. Further, the Parties acknowledge and agree that their respective proposals and all information exchanged in connection with the expert proceedings, and the conduct of such proceedings and any information produced thereunder shall be Confidential Information under this Agreement and subject to the provisions of Article 11.

Exhibit 12.1

Press Release

Affimed and Artiva Biotherapeutics Announce Partnership to Advance Combination Therapy of Innate Cell

Engager (ICE^®) AFM13

and Off-the-Shelf Allogeneic NK Cell Therapy AB-101

• Companies to combine their clinical programs (AFM13, AB-101) to address high unmet need of CD30-positive lymphoma patients

• Affimed’s AFM13 in combination with cord blood-derived NK cells demonstrated exceptionally high response rates in relapsed and refractory CD30-positive lymphoma patients

• AB-101 is a clinical-stage, cryopreserved, off-the shelf, non-genetically modified, allogeneic cord blood-derived NK cell manufactured at large scale via Artiva’s AlloNKTM platform as a universal ADCC-enhancing cell therapy

• In preclinical studies, the combination of AFM13 and AB-101 demonstrated potent anti-tumor activity

• An investigational new drug (IND) submission to the U.S. Food and Drug Administration (FDA) is planned for the first half of 2023

• Affimed to receive 67% of the combination therapy revenues, and Artiva to receive 33%

• Companies to host conference call/webcast later today at 10:30 am EDT

San Diego and Heidelberg, Germany, November X, 2022 - Affimed N.V. (Nasdaq: AFMD) (“Affimed”), and Artiva Biotherapeutics Inc. (“Artiva”), both immuno-oncology companies focused on developing and commercializing therapies utilizing the innate immune system, today announced a new strategic partnership to jointly develop, manufacture, and commercialize a combination therapy comprised of Affimed’s Innate Cell Engager (ICE^®) AFM13 and Artiva’s cord blood-derived, cryopreserved off-the-shelf allogeneic NK cell product candidate, AB-101.

Affimed submitted a pre-IND meeting request for the AFM13 and AB-101 combination to the FDA requesting feedback on the clinical trial design in relapsed/refractory (r/r) Hodgkin lymphoma (HL) with an exploratory arm evaluating the combination in selected subtypes of r/r CD30-positive peripheral T-cell lymphoma (PTCL) and potential path to registration. FDA responded to this request and guided to providing feedback by Q1 2023.

This clinical agreement follows the parties’ existing two-year preclinical collaboration to assess combining elements of the companies’ respective platforms in the generation of targeted, off-the-shelf allogeneic NK cell therapies.

“Based on the compelling clinical data we have generated for AFM13 in combination with NK cells, we are committed to finding the fastest path to bringing this potentially life-changing treatment to lymphoma patients,” said Dr. Adi Hoess, CEO of Affimed. “The allogeneic NK field is still at a nascent stage, and we selected Artiva because of their commercially-viable production process that can support a multicenter clinical trial and potentially enable a path to registration.”

“We are developing AB-101 as a universal ADCC enhancer when combined with monoclonal antibodies and NK cell engagers,” said Dr. Fred Aslan, CEO of Artiva. “The data Affimed has generated to date with AFM13 in combination with cord blood-derived NK cells in a patient population with great unmet need is very compelling, and we are excited to partner with Affimed on what could become one of the first approvals for an allogeneic NK cell therapy-based regimen.”

AFM13 is currently being investigated in combination with allogeneic cord blood-derived NK cells (CBNK) in an investigator-sponsored study together with The University of Texas MD Anderson Cancer Center. Data from this study published earlier today for presentation at the 64th ASH Annual Meeting and Exposition demonstrated that all 24 patients in the recommended Phase 2 dose cohort responded (overall response rate of 100%) and showed a complete response rate of 70.8%. The combination was well tolerated with few infusion-related reactions and without cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, or graft versus host disease.

The Affimed-Artiva partnership aims to expedite further development of the combination therapy in CD30-positive lymphoma patients who have exhausted other treatment options. AB-101 has already completed a monotherapy safety cohort in an initial Phase 1 trial and is currently being assessed in combination with the anti-CD20 monoclonal antibody, rituximab, in patients with relapsed or refractory non-Hodgkin lymphoma (NHL). Preclinical results investigating the combination of AFM13 and AB-101 have further demonstrated enhanced anti-tumor activity. The companies plan to file an IND for the program in relapsed/refractory CD30-positive lymphoma patients during the first half of 2023.

Under the terms of the agreement, Affimed and Artiva will pursue the development of the AFM13/AB-101 combination treatment in the United States on a co-exclusive basis. Affimed will lead regulatory activities through the Phase 2 and any confirmatory studies.

About AFM13

AFM13 is a first-in-class innate cell engager (ICE^®) that uniquely activates the innate immune system to destroy CD30-positive hematologic tumors. AFM13 induces specific and selective killing of CD30-positive tumor cells, leveraging the power of the innate immune system by engaging and activating natural killer (NK) cells and macrophages. AFM13 is Affimed’s most advanced ICE^® clinical program and is currently being evaluated as a monotherapy in a registration-directed trial in patients with relapsed/refractory peripheral T-cell lymphoma or transformed mycosis fungoides (REDIRECT). Additional details can be found at www.clinicaltrials.gov (NCT04101331).

About AB-101

AB-101 is a cord blood-derived, allogeneic, cryopreserved, ADCC-enhancing NK cell therapy candidate for use in combination with monoclonal antibodies or innate-cell engagers. Artiva selects cord blood units with the high affinity variant of the receptor CD16 and a KIR-B haplotype for enhanced product activity. Artiva can generate thousands of doses of pure, cryopreserved, infusion-ready NK cells from a single umbilical cord blood unit while retaining the high and consistent expression of CD16 without the need for engineering. Artiva is conducting a Phase 1/2 multicenter clinical trial (ClinicalTrials.gov Identifier: NCT04673617) to assess the safety and clinical activity of AB-101 alone and in combination with the anti-CD20 monoclonal antibody, rituximab, in patients with relapsed or refractory B-cell-non-Hodgkin lymphoma (NHL) who have progressed beyond two or more prior lines of therapy.
