Collaborative and Other Relationships | Collaborative and Other Relationships Government Collaborations National Institute of Allergy and Infectious Diseases (“NIAID/HHS”) In September 2013, NIAID/HHS contracted with the Company for the development of galidesivir as a treatment for Marburg virus disease and subsequently, Yellow Fever and Ebola virus disease. On September 15, 2021, the Company entered into an amendment to pay for certain additional costs, including additional manufacturing development costs and overhead, and to change the total value of the contract, as amended, to $47,315 from $45,931. All options under the contract have been awarded. In August 2020, NIAID/HHS awarded the Company a new contract, with potential aggregate funding of up to $43,908 if all contract options were exercised, to manufacture and evaluate the safety, efficacy and tolerability of galidesivir. NIAID/HHS made an initial award of $6,326 to the Company under this contract. Revenue related to this contract was recognized during the years ended December 31, 2022 and 2021. Biomedical Advanced Research and Development Authority (“BARDA/HHS”) In March 2015, BARDA/HHS awarded the Company a contract for the continued development of galidesivir as a potential treatment for diseases caused by RNA pathogens, including filoviruses. This BARDA/HHS contract included a base contract of $16,265 to support galidesivir drug manufacturing, as well as $22,855 in additional development options that could be exercised by the government, bringing the potential value of the contract to $39,120. As of December 31, 2022, a total of $20,574 was awarded under exercised options within this contract. The most recent development option was completed as of December 31, 2022. The contracts with NIAID/HHS and BARDA/HHS were cost-plus-fixed-fee contracts. That is, the Company was entitled to receive reimbursement for all costs incurred in accordance with the contract provisions that were related to the development of galidesivir plus a fixed fee, or profit. BARDA/HHS and NIAID/HHS made periodic assessments of progress, and the continuation of the contracts was based on the Company’s performance, the timeliness and quality of deliverables, and other factors. The government had rights under certain contract clauses to terminate these contracts. These contracts were terminable by the government at any time for breach or without cause. As of December 31, 2022, all of the Company’s government funding for galidesivir had expired. U.S. Department of Health and Human Services (“HHS”) In September 2018, HHS awarded the Company a $34,660 contract for the procurement of up to 50,000 doses of RAPIVAB (peramivir injection) over a five-year period. The Company initially delivered 20,000 doses of RAPIVAB under this contract in 2019 for a total price of approximately $13,864. The Company further delivered 20,000 and 9,980 doses of RAPIVAB in 2022 and 2021, respectively, and recorded revenue of $13,864 and $6,918 for the years ending December 31, 2022 and 2021, respectively. As of December 31, 2022, the Company had delivered a total of 49,980 RAPIVAB doses of the 50,000 RAPIVAB doses available under the contract, effectively completing the contract with HHS. ORLADEYO Torii Pharmaceutical Co., Ltd. (“Torii”) On November 5, 2019, the Company entered into a Commercialization and License Agreement with Torii (the “Original Torii Agreement”), granting Torii the exclusive right to commercialize ORLADEYO for the prevention of hereditary angioedema (“HAE”) attacks in Japan. Under the Original Torii Agreement, the Company received an upfront, non-refundable payment of $22,000. The Company received an additional milestone payment of $15,000 in the second quarter of 2021 upon receipt from the Japanese NHI of a reimbursement price approval for ORLADEYO. In addition, the Company was entitled to receive tiered royalty payments, ranging from 20% to 40% of annual net sales of ORLADEYO in Japan during each calendar year. Torii’s royalty payment obligations were subject to customary reductions in certain circumstances, but could not be reduced by more than 50% of the amount that otherwise would have been payable to the Company in the applicable calendar quarter. The Company identified performance obligations under the Original Torii Agreement related to (i) the license to develop and commercialize ORLADEYO, (ii) regulatory approval support, and (iii) reimbursement pricing approval support. These were each determined to be distinct from the other performance obligations. The Company allocated the $22,000 upfront consideration to the identified performance obligations using estimation approaches to determine the standalone selling prices under ASC Topic 606. Specifically, in determining the value related to the license, a valuation approach utilizing risk adjusted discounted cash flow projections was used, and an expected cost plus margin approach was utilized for the other performance obligations. On November 30, 2023, the Company entered into an Amended and Restated Commercialization and License Agreement with Torii (as amended, the “Torii Agreement”). Under the Torii Agreement, the Company is entitled to receive tiered royalty payments, ranging from 20% to 80% of annual net sales of ORLADEYO in Japan during each calendar year. The Company is now responsible for all commercial promotion activities to support ORLADEYO sales in Japan, and Torii is responsible for HAE disease awareness activities in Japan. The Company will receive a 20% royalty on annual Japanese sales below a prespecified threshold and an 80% royalty on annual Japanese sales above the prespecified threshold. Torii’s updated royalty payment obligations commenced upon November 30, 2023 and expire upon the later of (i) the tenth anniversary of the date of first commercial sale of ORLADEYO in Japan, (ii) the expiration of the Company’s patents covering ORLADEYO, and (iii) the expiration of regulatory exclusivity for ORLADEYO in Japan. The Company determined that the Torii Agreement represented a contract modification to be accounted for as if it were part of the Original Torii Agreement under ASC Topic 606. As the performance obligations under the Original Torii agreement had been fully satisfied, the Company was not required to adjust revenue previously recognized. Peramivir Injection (RAPIVAB, RAPIACTA, PERAMIFLU) Shionogi & Co., Ltd. (“Shionogi”) In February 2007, the Company entered into an exclusive license agreement with Shionogi to develop and commercialize peramivir in Japan for the treatment of seasonal and potentially life-threatening human influenza. Under the terms of the agreement, Shionogi obtained rights to injectable formulations of peramivir in Japan. In October 2008, the Company and Shionogi amended the license agreement to expand the territory covered by the agreement to include Taiwan. Shionogi has commercially launched peramivir under the commercial name RAPIACTA in Japan and Taiwan. The Company developed peramivir under a license from UAB and will owe sublicense payments to UAB on any future milestone payments and/or royalties received by the Company from Shionogi. Green Cross Corporation (“Green Cross”) In June 2006, the Company entered into an agreement with Green Cross to develop and commercialize peramivir in Korea. Under the terms of the agreement, Green Cross is responsible for all development, regulatory, and commercialization costs in Korea and the Company is entitled to share in profits resulting from the sale of peramivir in Korea, including the sale of peramivir to the Korean government for stockpiling purposes. Furthermore, Green Cross will pay the Company a premium over its cost to supply peramivir for development and any future marketing of peramivir products in Korea. Other Collaborations Clearside Biomedical, Inc. (“Clearside”) On November 3, 2023, the Company announced that it entered into a license agreement (the “Clearside Agreement”) with Clearside, enabling the Company to develop its investigational plasma kallikrein inhibitor, avoralstat, with Clearside’s SCS Microinjector® to deliver avoralstat to the back of the eye through the suprachoroidal space to treat patients with diabetic macular edema. Under the Clearside Agreement, Clearside received a $5,000 upfront license fee from the Company, which has been recognized in research and development expenses during the year ended December 31, 2023. Clearside is eligible to receive up to an additional $30,000 in clinical and regulatory milestone payments, and up to a total of $47,500 in three post-approval sales-based milestone payments as annual global net sales progress to $2,000,000. The Company will pay Clearside tiered mid-single digit royalties on annual global net product sales, at three tiers, including a top tier of >$1,500,000.
