In January 2021, the Company entered into a Support Services Agreement (the "2021 Support Services Agreement") with COI Pharmaceuticals, Inc. (“COI”) that outlines the terms of services provided by COI to the Company, as well as the fees charged for such services. COI is a shared service company that provides certain back-office and administrative and research and development support services, including facilities support, to the portfolio companies of Avalon Ventures, an entity that beneficially owns greater than 5% of our outstanding capital stock. The 2021 Support Services Agreement was most recently renewed in January 2023 and will continue to renew for additional one-year renewal periods until terminated by the parties. Either party may terminate the 2021 Support Services Agreement with 30 days written notice.
