Fusion Licenses Actinium-Based PSMA Targeted Radiotherapy From Heidelberg University and Euratom

Fusion Pharmaceuticals Inc. announced that it has entered into an exclusive worldwide license agreement with Heidelberg University and Euratom represented by the European Commission, Joint Research Centre (together, the "Licensors"). The license agreement grants Fusion exclusive worldwide rights to utilize, develop, manufacture and commercialize compounds covered by the patent, which includes 225Ac-PSMA I&T ("FPI-2265") for the treatment of prostate specific membrane antigen (PSMA)-expressing cancers. In addition, Fusion and the Licensors have signed an agreement to settle the parties' dispute related to an inter partes review ("IPR") of a US patent owned by the Licensors which was instituted in August 2023 by the United States Patent and Trademark Board.

Fusion President and Chief Business Officer Mohit Rawat said, "We are pleased to enter into this exclusive license agreement with Heidelberg University and Euratom for their existing patent as we progress FPI-2265, the most advanced actinium-based PSMA targeted radiotherapy currently in development. With Fusion's expertise in the development and manufacturing of alpha-emitting radiopharmaceuticals, an operational radiopharmaceutical manufacturing facility, and our advantageous actinium supply, we are well positioned to execute this program. We look forward to providing updates as we reach anticipated upcoming milestones in 2024, including data from the TATCIST study in April and the initiation of our Phase 2/3 registrational study in the second quarter."

As announced in January 2024, Fusion and the US Food and Drug Administration reached alignment on Fusion's Phase 2/3 protocol for FPI-2265 in patients with mCRPC who have progressed following treatment with lutetium-based radiopharmaceuticals. The updated development plan includes a Phase 2 dose optimization lead-in, expected to complete enrollment by the end of 2024, and a Phase 3 registrational trial expected to begin in 2025.

Under the terms of the license agreement, Fusion will pay the Licensors an aggregate upfront fee of €1.0 million, in addition to certain regulatory milestones upon potential approval and low single-digit royalties on future net sales of applicable products.
