Varegacestat

BOTHELL, Wash.--(BUSINESS WIRE)--Immunome, Inc. (Nasdaq: IMNM), a biotechnology company focused on developing first-in-class and best-in-class targeted cancer therapies, today announced financial results for the quarter ended March 31, 2025 and provided a business update. “Immunome continued to build momentum in the first quarter of 2025,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer. “We remain on track to share topline data for the RINGSIDE trial of varegacestat in the second half of 2025, and we are optimistic that varegacestat will demonstrate differentiated efficacy across multiple endpoints. “Varegacestat is complemented by a robust pipeline of differentiated programs with first-in-class or best-in-class potential. The dose escalation portion of the Phase 1 clinical trial of IM-1021, our ROR1 ADC, is ongoing in solid tumors and lymphoma. Following the recent clearance of the IND for IM-3050, our FAP radiotherapy, we expect to start a clinical trial for that program in the second half of this year. We are making progress on IND-enabling manufacturing for IM-1617, IM-1335 and IM-1340, each of which incorporate our differentiated TOP1 inhibitor, HC74.” Pipeline Highlights Varegacestat: Full enrollment for the Phase 3 RINGSIDE Part B study of varegacestat for the treatment of desmoid tumors was completed in February 2024, and Immunome expects to report topline data for RINGSIDE Part B in the second half of 2025. In parallel, Immunome is performing the manufacturing and pharmacology work required to support a new drug application filing for varegacestat. IM-1021: The Phase 1 clinical trial of IM-1021 is ongoing, with the first patient dosed in February 2025. The trial is an open-label, multicenter dose-escalation and expansion study that is expected to include participants with advanced B-cell lymphomas and advanced solid tumors. IM-3050: Immunome received IND clearance for IM-3050 in April 2025 and expects to initiate a Phase 1 clinical trial in the second half of 2025. Preclinical Pipeline: Immunome’s three preclinical ADCs against solid tumor targets, IM-1617, IM-1340 and IM-1335, each of which incorporates HC74, are currently undergoing IND-enabling work. Additional undisclosed ADCs are in discovery and lead optimization. First Quarter 2025 Financial Results As of March 31, 2025, cash, cash equivalents and marketable securities totaled $317.3 million. This total includes net proceeds of $161.7 million from the January 2025 financing and reflects approximately $11 million in payments during the quarter related to non-recurring IM-1021 milestones and 2024 annual performance bonuses. Immunome expects its current cash position to fund operations into 2027.
