For the three and six months ended June 30, 2021 and 2020, the Company recognized revenue for its collaborations with Genentech Inc. (“Genentech”), AstraZeneca AB (“AstraZeneca”), and the Dementia Discovery Fund (“DDF”). The following table summarizes the revenue recognized in the Company’s condensed consolidated statements of operations and comprehensive loss from these arrangements (in thousands):

On February 21, 2020, the Company entered into a Discovery Collaboration and License Agreement (the “Genentech Collaboration Agreement”) with Genentech. The collaboration is focused on the discovery and development of Bicycle peptides directed to biological targets selected by Genentech and aimed at developing up to four potential development candidates against multiple immuno-oncology targets suitable for Genentech to advance into further development and commercialization.

Under the terms of the Genentech Collaboration Agreement, Bicycle received a $30.0 million upfront, non-refundable payment. The initial discovery and optimization activities will focus on utilizing Bicycle’s phage screening technology to identify product candidates aimed at two immuno-oncology targets (“Genentech Collaboration Programs”), which may also include additional discovery and optimization of Bicycles as targeting elements for each Genentech Collaboration Program (each a “Targeting Arm”). Genentech has the option to nominate up to two additional immuno-oncology targets (each, an “Expansion Option”), which may also include an additional Targeting Arm for each Expansion Option, as additional Genentech Collaboration Programs during a specified period following completion of certain activities under an agreed research plan. If Genentech exercises one or more Expansion Options, Genentech will pay to the Company an expansion fee of $10.0 million per Expansion Option. Genentech also has rights, under certain limited circumstances, to select an alternative target to be the subject of a Genentech Collaboration Program, in some cases subject to payment of an additional target selection fee.

If Genentech elects for Bicycle to perform discovery and optimization services for certain Targeting Arms, the Company will be entitled to receive an additional advance payment for the additional research services. Genentech

exercised its right to select a Targeting Arm for one of the initial Genentech Collaboration Programs at the inception of the arrangement, which entitled the Company to an additional $1.0 million payment. If a Targeting Arm achieves specified criteria in accordance with the research plan, Genentech will be required to pay a further specified amount in the low single digit millions for each such Targeting Arm as consideration for the additional services to be provided.

Bicycle granted to Genentech a non-exclusive research license under Bicycle’s intellectual property solely to enable Genentech to perform any activities under the agreement. The activities under the Genentech Collaboration Agreement are governed by a joint research committee (“JRC”) with representatives from each of the Company and Genentech. The JRC will oversee, review and recommend direction of each Genentech Collaboration Program, achievement of development criteria, and variations of or modifications to the research plans.

After the Company performs the initial discovery and optimization activities in accordance with an agreed research plan and achieves specified criteria, Genentech will have the option to have the Company perform initial pre-clinical development and optimization activities in exchange for an additional specified milestone payment in the mid-single digit millions for each Genentech Collaboration Program (the “LSR Go Option”). Upon completion of such initial pre-clinical development and optimization activities for each Genentech Collaboration Program, Genentech will have the option to obtain an exclusive license to exploit any compound developed under such Genentech Collaboration Program in exchange for an additional specified payment in the mid to high single digit millions for each of the initial two Genentech Collaboration Programs and each of the two Expansion Option Genentech Collaboration Programs (the “Dev Go Option”).

On a Genentech Collaboration Program by Genentech Collaboration Program basis, if Genentech elects to obtain exclusive development and commercialization rights and pays the applicable LSR Go Option and Dev Go Option fees, Genentech will be required to make milestone payments to the Company upon the achievement of specified development, regulatory, and initial commercialization milestones for products arising from each collaboration program, totaling up to $200.0 million. Specifically, the Company is eligible for additional development milestones totaling up to $65.0 million, as well as regulatory milestones of up to $135.0 million for each collaboration program. In addition, the Company is also eligible to receive up to $200.0 million in sales milestone payments on a Genentech Collaboration Program-by-Genentech Collaboration Program basis. In addition, to the extent any of the product candidates covered by the licenses conveyed to Genentech are commercialized, the Company would be entitled to receive tiered royalty payments on net sales at percentages ranging from the mid-single to low double-digits, subject to certain standard reductions and offsets. Royalties will be payable, on a product by product and country by country basis, until the later of the expiration of specified licensed patents covering such product in such country, or ten years from first commercial sale of such product in such country.

Upon the execution of the Genentech Collaboration Agreement, the Company has identified the following performance obligations:

The Company concluded that certain substitution rights that require the payment of additional consideration, which approximate the standalone selling price of the underlying services to be provided, do not provide the customer with a material right and therefore, are not considered as performance obligations and are accounted for as separate contracts upon exercise, if ever. The Company’s participation in the joint steering committee was assessed as immaterial in the context of the contract.

The Company has concluded that the research license is not distinct from the research and development services as Genentech cannot obtain the benefit of the research license without the Company performing the research and development services. The services incorporate proprietary technology and unique skills and specialized expertise, particularly as it relates to constrained peptide technology that is not available in the marketplace. As a result, for each research program, the research license has been combined with the research and development services into a single performance obligation. In addition, the Company concluded that the Dev Go Option is not distinct or separately exercisable from the LSR Go Option, as the customer cannot benefit from the Dev Go Option unless and until the LSR Go Option is exercised.

In assessing whether the various options under the Genentech Collaboration Agreement represent material rights, the Company considered the additional consideration the Company would be entitled to upon the option exercise, the standalone selling price of the underlying goods, services, and additional options. For the material rights identified above the Company concluded that each of the options provided Genentech with a discount that it otherwise would not have received.

The total transaction price was initially determined to be $31.0 million, consisting of the $30.0 million upfront fee and the additional $1.0 million for Genentech’s selection of a new Targeting Arm at inception. The Company utilizes the most likely amount method to determine the amount of research and development funding to be received. Additional consideration to be paid to the Company upon the exercise of options by Genentech and subsequent milestones are excluded from the transaction price as they relate to option fees and milestones that can only be achieved subsequent to the exercise of an option. In addition, other variable consideration for development milestones not subject to option exercises was fully constrained, as a result of the uncertainty regarding whether any of the milestones will be achieved.

In March 2021, the Company achieved specified criteria in accordance with the research plan under the Genentech Collaboration agreement and therefore updated its estimate of the variable consideration to include an additional $2.0 million, that is no longer constrained. The arrangement consideration was increased to $33.0 million.

exercise the option and any underlying options. Based on the relative standalone selling price, the allocation of the transaction price as of June 30, 2021 to the separate performance obligations is as follows (in thousands):


	Allocation of
Performance Obligations	Transaction Price
Genentech Collaboration Program #1 Performance Obligation	$	4,019
Genentech Collaboration Program #2 Performance Obligation		8,037
Specified Targeting Arm Material Right Arm for Genentech Collaboration Program #1		352
Two material rights associated with the LSR Go Option for Collaboration Programs #1 and #2		12,400
Material rights associated with limited substitution rights		1,187
Two material rights for Expansion Options		7,005
	$	33,000

The Company is recognizing revenue related to amounts allocated to the Genentech Collaboration Program #1 and #2 Performance Obligations as the underlying services are performed using a proportional performance model over the period of service using input-based measurements of total full-time equivalent efforts and external costs incurred to date as a percentage of total full-time equivalent time and external expected, which best reflects the progress towards satisfaction of the performance obligation. The amount allocated to the material rights is recorded as deferred revenue and the Company commences revenue recognition upon exercise of or upon expiry of the respective option. The Company anticipates that the Genentech Collaboration Performance Program #1 and #2 obligations will be performed over a period of approximately two years, and the material rights will be exercised or expire within approximately four years from contract execution.

During the three and six months ended June 30, 2021, the Company recognized revenue of $1.6 million and $3.1 million, respectively, and during the three and six months ended June 30, 2020, the Company recognized revenue of $1.2 million and $1.9 million, respectively. As of June 30, 2021 and December 31, 2020, the Company recorded $26.9 million and $27.6 million, respectively, of deferred revenue in connection with the Genentech Collaboration Agreement.

Dementia Discovery Fund Agreement

In May 2019, the Company entered into a collaboration with the DDF to use Bicycle technology for the discovery and development of novel therapeutics for dementia (the “DDF Collaboration Agreement”). In October 2019, the collaboration with DDF was expanded to include Oxford University’s Oxford Drug Discovery Institute (“ODDI”). Under the terms of the DDF Collaboration Agreement, the Company and DDF will collaborate to identify Bicycles that bind to clinically validated dementia targets (the “DDF Research Plan”). The Company is obligated to use commercially reasonable efforts to perform research activities under the DDF Research Plan. DDF shall not be directly engaged in the conduct of any research activities under the arrangement. ODDI will then profile these Bicycles in a range of target-specific and disease-focused assays to determine their therapeutic potential. The activities under the DDF Collaboration Agreement will be governed by a project advisory panel, composed of two representatives from the Company and DDF. The Research Advisory Panel will oversee, review and recommend direction for the Research Plans and variations of or modifications of research plans.

The Company received an upfront payment of $1.1 million in May 2019. The DDF arrangement provided the Company could receive up to an additional $0.7 million, of which $0.5 million has been received as of June 30, 2021, upon achievement of certain milestones such as the identification of lead Bicycle candidates with a certain affinity, which would be used to fund additional research and development services including lead optimization.

Intellectual property created by the collaboration shall be owned by the Company, and background intellectual property improvements shall be owned by the party from whose background intellectual property they exclusively relate. If promising lead compounds are identified, the Company, ODDI and DDF have the option (the “DDF Option”) to establish a jointly owned new company (“NewCo”) to advance the compounds through further development towards commercialization. NewCo will receive a royalty and milestone-bearing assignment and license of intellectual property from the Company for this purpose. The DDF Option is exercisable at any time until 90 days following the completion

of the Research Plan and delivery of a final report. If DDF does not elect to exercise the DDF Option during the Option period, then DDF shall have no right in the collaboration intellectual property. NewCo will initially be owned 66% by the Company and 34% by DDF; however, the Company shall not be entitled to exercise more than 50% of the total voting rights related to its ownership interests. After completion of the DDF Option exercise, for a period of two years following the option exercise, NewCo shall have the right to initiate a new research program to develop up to three additional dementia targets, on a target by target basis, and the Company will be entitled to charge NewCo an agreed upon FTE rate for peptide screening and optimization for the active targets.

Either party may terminate the DDF Collaboration Agreement upon providing not less than 60 days written notice. A party may terminate the DDF Collaboration Agreement with immediate effect without notice if at any time the other party files for protection under bankruptcy or insolvency laws, makes an arrangement for the benefit of creditors, appoints a receiver, administrator, manager or trustee over its property, proposes a written agreement of composition or extension of its debts, is a party to any dissolution, winding-up or liquidation, or is in material breach that has not been remedied.

Accounting Analysis

The Company identified a single performance obligation associated with the performance of research and development services under the DDF Research Plan.

The Company concluded that the DDF Option is an immaterial obligation at the inception of the arrangement, as it represents a right to acquire shares of NewCo that have de minimis value. The DDF Option also does not contain a material right that otherwise would not have been received. The Company’s participation in the Research Advisory Panel was assessed as immaterial in the context of the contract. In addition, the Company concluded that the option for NewCo to obtain additional peptide screening and optimization services is not an obligation at the inception of the arrangement, as they are optional services and the amount that will be paid for the services do not reflect a discount that the customer would otherwise receive and do not provide the customer with material rights.

The total transaction price was initially determined to be $1.1 million, consisting of the upfront payment for research and development funding. The Company may receive additional milestone payments during the DDF Research Plan, as well as for research and development services for additional targets following the exercise of DDF Option. These variable amounts are excluded from the transaction price as they relate to fees that can only be achieved subsequent to the exercise of an option, and therefore are treated as separate contracts.

The transaction price was allocated to the single performance obligation of research and development services. The Company is recognizing revenue as the underlying services are performed using a proportional performance model, over the period of service using input-based measurements of total costs, including total full-time equivalent effort incurred to date as a percentage of total costs expected, which best reflects the progress towards satisfaction of the performance obligation. In December 2020, the Company received a payment of $0.5 million upon the achievement of specified scientific criteria. The Company concluded that the payment represents consideration for a single performance obligation to perform lead optimization activities, and will recognize revenue as the underlying services are performed using a proportional performance model, over the period of service using input based measurements of total costs, including total full time equivalent effort incurred to date as a percentage of total costs expected, which best reflects the progress towards satisfaction of the performance obligation.

For each of the three and six months ended June 30, 2021, the Company recognized $0.2 million of revenue, and for each of the three and six months ended June 30, 2020, the Company recognized $0.1 million of revenue, related to its collaboration with DDF. As of June 30, 2021 and December 31, 2020, the Company recorded deferred revenue of $0.6 million and $0.8 million, respectively, related to its collaboration with DDF.

AstraZeneca Collaboration Agreement

In November 2016, the Company entered into a Research Collaboration Agreement (the “AstraZeneca Collaboration Agreement” with AstraZeneca. The collaboration activities initially focused on two targets within

respiratory, cardiovascular and metabolic disease, for which collaboration activities were terminated by AstraZeneca in October 2020 and March 2021, respectively.

In May 2018, AstraZeneca made an irrevocable election to exercise an option to nominate up to four additional targets (“Additional Four Target Option”). As a result, AstraZeneca was entitled to obtain research and development services from the Company with respect to Bicycle peptides that bind to up to four additional targets, along with license rights to those selected targets, in exchange for an option fee of $5.0 million. After discovery and initial optimization of such Bicycle peptides, AstraZeneca is responsible for all research and development, including lead optimization and drug candidate selection. AstraZeneca has option rights, at drug candidate selection, which allow it to obtain development and exploitation license rights with regard to such drug candidate. Each research program is to continue for an initial period of three years, referred to as the research term, including one year for the Bicycle Research Term and two years for the AZ Research Term. AstraZeneca may extend the research term for each research program by twelve months (or fifteen months, if needed to complete certain toxicology studies) or may shorten the research term for a research program if it is ceased due to a screening failure, a futility determination, or abandonment by AstraZeneca. AstraZeneca had certain target substitution rights should a screening failure or futility determination be reached, but was obligated to fund these additional efforts related to substitution. AstraZeneca was obligated to fund two FTEs during the Bicycle Research Term, for each research program, based on an agreed upon FTE reimbursement rate. AstraZeneca has the option to obtain worldwide development and commercialization licenses associated with each designated drug candidate in return for a fee of $8.0 million per drug candidate, upon the selection of such drug candidate. AstraZeneca is required to make certain milestone payments to the Company upon the achievement of specified development, regulatory and commercial milestones. More specifically, for each research program, the Company is eligible to receive up to $29.0 million in development milestone payments and up to $23.0 million in regulatory milestone payments. The Company is also eligible for up to $110.0 million in commercial milestone payments, on a research program by research program basis. In addition, to the extent any of the drug candidates covered by the licenses conveyed to AstraZeneca are commercialized, the Company would be entitled to receive tiered royalty payments of mid-single digits based on a percentage of net sales, subject to certain reductions, including in certain countries where the licensed product faces generic competition. AstraZeneca may terminate the AstraZeneca Collaboration Agreement, entirely or on a licensed product by licensed product or country by country basis, for convenience.

Accounting Analysis

Upon the execution of the Additional Four Target Option, the Company identified the following five performance obligations associated with the May 2018 AstraZeneca Agreement:

(i)

Research license and the related research and development services during the Bicycle Research Term for the third target (the “Target Three Research License and Related Services”),

(ii)

Material right associated with the development and exploitation license option for the third target (“Target Three Material Right”),

(iii)

Material right associated with the research services option, including the underlying development and exploitation license option for the fourth target (“Target Four Material Right”),

(iv)

Material right associated with the research services option, including the underlying development and exploitation license option for the fifth target (“Target Five Material Right”), and

(v)

Material right associated with the research services option, including the underlying development and exploitation license option for the sixth target (“Target Six Material Right”).

The Company concluded that the fourth, fifth and sixth targets available for selection are options. Upon exercise, AstraZeneca will obtain a research license and the related research and development services and an option to a development and exploitation license. The Company has concluded that the research services option, including the underlying development and exploitation license options related to each respective target results in a material right as the

option exercise fee related to the development and exploitation license contains a discount that AstraZeneca would not have otherwise received.

The research license and the related research and development services related to the fourth, fifth and sixth targets were not performance obligations at the inception of the arrangement, as they are optional services that will be performed if AstraZeneca selects additional targets and they reflect their standalone selling prices and do not provide the customer with material rights. The Company’s participation in the joint steering committee was assessed as immaterial in the context of the contract.

The total transaction price was initially determined to be $5.7 million, consisting of the $5.0 million option exercise fee and research and development funding of an estimated $0.7 million. The research and development funding is being provided based on the costs that are incurred to conduct the research and development services. The Company utilizes the most likely amount method to determine the amount of research and development funding to be received. Additional consideration to be paid to the Company upon the exercise of the license options by AstraZeneca or upon reaching certain milestones are excluded from the transaction price as they relate to option fees and milestones that can only be achieved subsequent to the license option exercise or are outside of the initial contact term.

The transaction price was allocated to the performance obligations based on the relative estimated standalone selling prices of each performance obligation. The estimated standalone selling prices for each Research License and Related Services obligation was primarily based on the nature of the services to be performed and estimates of the associated effort and costs of the services, adjusted for a reasonable profit margin what would be expected to be realized under similar contracts. The estimated standalone selling price for the material rights was determined based on the fees AstraZeneca would pay to exercise the license options, the estimated value of the License Option using comparable transactions, and the probability that (i) AstraZeneca would opt into the target development, and (ii) the license options would be exercised by AstraZeneca. Based on the relative standalone selling price, the allocation of the transaction price to the separate performance obligations was as follows (in thousands):


	Allocation of
Performance Obligations	Transaction Price
Target Three Research License and Related Services	$	650
Target 3 Material Right		1,504
Target 4 Material Right		1,204
Target 5 Material Right		1,165
Target 6 Material Right		1,127
	$	5,650

The Company recognized revenue related to amounts allocated to the Target Three Research License and Related Services as the underlying services are performed using a proportional performance model over the period of service using input-based measurements of total full-time equivalent effort incurred to date as a percentage of total full-time equivalent time expected, which best reflected the progress towards satisfaction of the performance obligation. The amount allocated to the material rights is recorded as deferred revenue and the Company commences revenue recognition upon exercise of or upon expiry of the option. The optional future research license and the related research and development services related to the fourth, fifth and sixth targets reflect their standalone selling prices and do not provide the customer with a material right and, therefore, are not considered performance obligations and are accounted for as separate contracts. In June 2019, AstraZeneca selected a replacement target for the third target, and as such a new Research Term was started related to the Target Three Research License and Related Services. The total transaction price under the arrangement increased to $6.3 million for the additional research and development funding to be received. In October 2020, AstraZeneca terminated the collaboration activities related to the third target. As a result, deferred revenue related to the amount allocated to the Target 3 Material Right of $1.5 million was recognized during the year ended December 31, 2020. As of June 30, 2021, three research programs were in the AZ Research Term, and the research and development services associated with the Bicycle Research Term the fourth, fifth and sixth targets have been completed.

For the three and six months ended June 30, 2021, the Company recognized zero and $0.3 million, respectively, of revenue related to the research and development services for the sixth target related to the exercise of the Additional Four Target Option, and for the three and six months ended June 30, 2020 the Company recognized $0.3 million and $0.7 million, respectively, of revenue for the Target Three Research License and Related Service, and research and development services for the fourth and fifth targets. As of June 30, 2021 and December 31, 2020, the Company recorded $3.6 million and $3.8 million, respectively, of deferred revenue in connection with the Additional Four Target Option and related contracts.

Evaluation and Option Agreement

On December 31, 2020 (the “Effective Date”), the Company entered into an Evaluation and Option Agreement (the “Evaluation and Option Agreement”) with Ionis Pharmaceuticals, Inc. (“Ionis”). Under the terms of the Evaluation and Option Agreement, the Company agreed to transfer Bicycles (the “Option Materials”) to Ionis in order to evaluate a particular application of the Company’s technology platform for a period of up to four months (the “Evaluation Period”). Ionis agreed to pay a non-refundable $3.0 million option fee within five business days after the Effective Date.

At any point during the term of the agreement and continuing through 30 days after the expiration of the Evaluation Period, Ionis had the option (the “Ionis Option”) to obtain an exclusive license to the Company’s intellectual property for the purpose of continued research, development, manufacture and commercialization of products within a particular application of the Company’s platform technology. The upfront payment of $3.0 million was fully creditable against the upfront payment paid upon the execution of a license agreement.

For both the three and six months ended June 30, 2021, the Company recognized zero revenue and $3.0 million of deferred revenue related to the Evaluation and Option Agreement. The Company concluded that the transaction price is $3.0 million, and all other amounts are excluded from the transaction price as they relate to fees that can only be achieved subsequent to the exercise of an option. The transaction price was allocated to the single performance obligation, an option to enter into a future license agreement which is a material right, as the Evaluation and Option Agreement payment is creditable against the upfront payments to be paid for a license agreement. The Company concluded that all other performance obligations were immaterial in the context of the contract. The Company will begin to recognize revenue when the Ionis Option is exercised or when the Ionis Option expires.

Summary of Contract Assets and Liabilities

Up-front payments and fees are recorded as deferred revenue upon receipt or when due until such time as the Company satisfies its performance obligations under these arrangements. A contract asset is a conditional right to consideration in exchange for goods or services that the Company has transferred to a customer. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.

Cancer Research UK

BT1718

On December 13, 2016, the Company entered into a Clinical Trial and License Agreement with Cancer Research Technology Limited (“CRTL”), a wholly owned subsidiary of Cancer Research UK that Cancer Research UK’s commercial activities operate through, and Cancer Research UK (the “Cancer Research UK Agreement”). Pursuant to the Cancer Research UK Agreement, as amended in March 2017 and June 2018, Cancer Research UK’s Centre for Drug Development will sponsor and fund a Phase I/IIa clinical trial for BT1718, a Bicycle Toxin Conjugate, in patients with advanced solid tumors.

Cancer Research UK is responsible for designing, preparing, carrying out and sponsoring the clinical trial at its cost. The Company is responsible for supplying agreed quantities of GMP materials for the trial, the supply of which has been completed. In the event that additional quantities are needed, the Company will provide Cancer Research UK with all reasonable assistance to complete the arrangements necessary for the generation and supply of such additional GMP materials, but Cancer Research UK will be responsible for supplying and paying for such additional quantities of GMP materials.

The Company granted Cancer Research UK a license to its intellectual property in order to design, prepare for, sponsor, and carry out the clinical trial. The Company retains the right to continue the development of BT1718 during the clinical trial. Upon the completion of the Phase I/IIa clinical trial, the Company has the right to obtain a license to the results of the clinical trial upon the payment of a milestone, in cash and ordinary shares, with a combined value in the mid six digit dollar amount. If such license is not acquired, or if it is acquired and the license is terminated and the Company decides to abandon development of all products that deliver cytotoxic payloads to the MT1 target antigen, the Company will assign or grant to CRTL an exclusive license to develop and commercialize the product on a revenue sharing basis (in which case the Company will receive tiered royalties of 70% to 90% of the net revenue depending on the stage of development when the license is granted). The Cancer Research UK Agreement contains additional future milestone payments upon the achievement of development and regulatory milestones, payable in cash and shares, with an aggregate total value of $50.9 million, as well as royalty payments based on a single digit percentage on net sales of products developed.

The Cancer Research UK Agreement can be terminated by either party upon an insolvency event, material breach of the terms of the contract, or upon a change in control (and the new controlling entity develops, sells or manufactures tobacco products or generates the majority of its profits from tobacco products or is an affiliate of such party). Cancer Research UK may also terminate the arrangement for safety reasons or if it determines that the objectives of the clinical trial will not be met. The Company was obligated to reimburse Cancer Research UK for certain costs if the Cancer Research UK agreement was terminated by Cancer Research UK prior to the completion of the dose escalation (Phase I) part of the clinical trial for an insolvency event of, or material breach by, the Company or upon termination for safety reasons or if Cancer Research UK determined that the objectives of the clinical trial would not be met, however, these reimbursement obligations expired unexercised upon the completion of the Phase I portion of the clinical trial in 2020. If the Company is subject to a change in control and the new controlling entity develops, sells or manufactures tobacco products or generates the majority of its profits from tobacco products or is an affiliate of such party prior to the last cycle of treatment under the Phase IIa clinical trial, the Company will reimburse Cancer Research UK in full for all costs paid or committed in connection with the clinical trial and no further license payments, where applicable, shall be due. In such case, Cancer Research UK will not be obliged to grant a license to the Company in respect of the results of the clinical trial and the Company will assign or grant to CRTL an exclusive license to develop and commercialize the product without CRTL being required to make any payment to the Company.

The Company concluded that the costs incurred by Cancer Research UK is a liability in accordance with ASC 730, Research and Development, as certain payments are not based solely on the results of the research and development having future economic benefit. As such, the Company recorded a liability of $3.0 million and $2.6 million at June 30, 2021 and at December 31, 2020, respectively, which is recorded in other long-term liabilities in the condensed consolidated balance sheets. The liability is recorded as incremental research and development expense in the condensed consolidated statements of operations and comprehensive loss.

BT7401

In December 2019, the Company entered into a clinical trial and license agreement with Cancer Research Technology Limited and Cancer Research UK. Pursuant to the agreement, Cancer Research UK’s Centre for Drug Development will fund and sponsor development of BT7401, a multivalent Bicycle CD137 agonist, from current preclinical studies through the completion of a Phase IIa trial in patients with advanced solid tumors.

The Company granted to Cancer Research UK a license to the Company’s intellectual property in order to design, prepare for, sponsor, and carry out the clinical trial and all necessary preclinical activities to support the trial. The Company retains the right to continue the development of BT7401 during the clinical trial. Upon the completion of the Phase I/IIa clinical trial, the Company has the right to obtain a license to the results of the clinical trial upon the payment of a milestone, in cash and ordinary shares, with a combined value in the mid six digit dollar amount. If such license is not acquired, or if it is acquired and the license is terminated and the Company decides to abandon development of all products that contain BT7401 or all the pharmaceutically active parts of BT7401, CRTL may elect to receive an exclusive license to develop and commercialize the product on a revenue sharing basis (in which case the Company will receive tiered royalties of 55% to 80% of the net revenue depending on the stage of development when the license is granted) less certain costs, as defined by the agreement. The BT7401 Cancer Research UK agreement contains additional future milestone payments upon the achievement of development, regulatory and commercial milestones, payable in cash, with an aggregate total value of up to $60.3 million for each licensed product, as well as royalty payments based on a single digit percentage on net sales of products developed, and sublicense royalties to the Cancer Research UK in the low double digit percentage of sublicense income depending on the stage of development when the license is granted.

The BT7401 Cancer Research UK agreement can be terminated by either party upon an insolvency event, material breach of the terms of the contract, or upon a change in control (and the new controlling entity develops, sells or manufactures tobacco products or generates the majority of its profits from tobacco products or is an affiliate of such party), or upon written notice by Cancer Research UK prior to the last cycle of treatment has been completed under the clinical trial. If the trial is terminated by the Company prior to the filing of a clinical trial authorization, or by Cancer Research UK for an insolvency event or a material breach by the Company prior to the start of a clinical trial, the Company will reimburse Cancer Research UK for certain costs paid or committed prior to the start of the clinical trial. In such case where the Company is subject to a change in control and the new controlling entity develops, sells or manufactures tobacco products or generates the majority of its profits from tobacco products or is an affiliate of such party, Cancer Research UK will not be obliged to grant a license to the Company in respect of the results of the clinical trial and CRTL may elect to receive an exclusive license to develop and commercialize the product without CRTL being required to make any payment to the Company. The Company concluded that the BT7401 Cancer Research UK arrangement does not represent a liability in accordance with ASC 730, Research and Development, as the payments are based solely on the results of the research and development having future economic benefit and risk of repayment is substantive and genuine, and as such there was no accounting impact as of June 30, 2021.
