Mosaic In October 2017, the Company entered into a strategic research collaboration with Mosaic Biosciences (“Mosaic”) to develop intravitreal anti-complement factor 3 (C3) products for the treatment of dry Age-related Macular Degeneration (AMD) and other retinal diseases. The Company subsequently amended this agreement in December 2018, December 2019 and May 2020. Under the as amended Mosaic collaboration agreement, Mosaic is eligible to receive up to $4.0 million in potential future milestone payments related to regulatory and clinical development events for CB 2782-PEG and an additional anti-complement product candidate in lieu of the Company’s prior obligations to pay Mosaic a double-digit percentage of funds the Company receives from Biogen or any other amounts the Company receives related to sublicense fees, research and development payments, or any other research, regulatory, clinical or commercial milestones and royalties on any other development candidates. As a result of the sale of the Company’s complement portfolio, including CB 2782-PEG and other assets, to Vertex in May 2022, the Mosaic collaboration agreement was transferred to Vertex (see Note 12). ISU Abxis In December 2018, the Company entered into an amended and restated license agreement with ISU Abxis (the “A&R ISU Abxis Agreement”). Under the A&R ISU Abxis Agreement, ISU Abxis will receive commercialization rights in South Korea to the Company’s engineered Factor IX dalcinonacog alfa - DalcA and the Company will receive clinical development and commercialization rights in the rest of world (excluding South Korea) and manufacturing development and manufacturing rights worldwide (including South Korea). The A&R ISU Abxis Agreement provides for a low single-digit royalty payment to ISU Abxis, on a country-by-country basis, for net product sales of DalcA by the Company or its affiliates in each country other than South Korea. Pursuant to the A&R ISU Abxis Agreement, the Company will also pay up to an aggregate of $19.5 million in milestone payments to ISU Abxis, including $2.5 million in regulatory and development milestone payments and up to $17.0 million in commercial milestone payments, if the applicable milestones are met. As of September 30, 2022, no milestones have been met. Biogen On December 18, 2019, the Company and Biogen International GmbH (“Biogen”) entered into a License and Collaboration Agreement (the “Biogen Agreement”), under which the Company granted Biogen a worldwide, royalty-bearing, exclusive, with the right to sublicense, license (“Exclusive License”) to develop and commercialize CB 2782-PEG and other anti-C3 proteases for potential treatment of dry AMD and other disorders. Pursuant to the Biogen Agreement, the Company performed certain pre-clinical and manufacturing activities (“Research Services”), and Biogen was solely responsible for funding the pre-clinical and manufacturing activities and performing IND-enabling activities, worldwide clinical development, and commercialization. Under the terms of the Biogen Agreement, the Company received an up-front payment for the transfer of the Exclusive License (inclusive of certain know-how) of $15.0 million in January 2020. The Company was eligible to receive development milestones and sales milestones of up to $340.0 million. In addition, the Company was eligible to receive royalties in the range of single-digit to low double-digit percentage rates of annual net sales on a product-by-product and country-by-country basis. The Company also received reimbursements for costs associated with the performance of the Research Services. The Company determined that the performance obligations under the Biogen Agreement were the Exclusive License and the Research Services. For the Exclusive License, the Company used the residual approach in determining the standalone selling price, or SSP, which includes the upfront payments, milestones and royalties. For the Research Services, the Company used the historical pricing approach for determining the SSP, which includes the reimbursement of personnel and out-of-pocket costs. In March 2022, the Company received written notice from Biogen declaring intent to terminate the Biogen Agreement which was effective as of May 2022. As a result of the termination, Biogen no longer has the Exclusive License to develop, manufacture and commercialize CB 2782-PEG and other anti-C3 proteases for potential treatment of dry AMD and other disorders. In March 2022, Biogen returned full rights to CB 2782-PEG. In June 2022, Biogen and the Company reached an agreement to resolve the outstanding obligations and monetary disputes between the parties. The Company agreed to forgive approximately $0.6 million of accounts receivable due from Biogen and to pay Biogen $10,000 in cash. This resulted in the Company recognizing a $0.6 million settlement expense for the three months ended June 30, 2022, which is included in general and administrative operating expenses in the condensed consolidated statements of operations. The Company recognized $0.0 million and $0.7 million of research and development expense as cost of collaboration revenue for the three and nine months ended September 30, 2022, respectively. The Company recognized $1.9 million and $4.3 million for the three and nine months ended September 30, 2021, respectively, of research and development expense as cost of collaboration revenue related to the Biogen Agreement. Research and development expenses were reimbursed by Biogen in accordance with the agreement. For the nine months ended September 30, 2022, the Company recognized $0.2 million of revenue from the beginning of period deferred revenue balance.
