Repare Therapeutics enters licensing pact with Debiopharm for Lunresertib

Repare Therapeutics (RPTX) announced it has entered into an exclusive worldwide licensing agreement with Debiopharm International S.A., a privately-owned, Swiss-based biopharmaceutical company aiming to establish tomorrow’s standards of care to cure cancer and infectious diseases, for lunresertib, a first-in-class precision oncology PKMYT1 inhibitor. “The exclusive worldwide licensing agreement with Debiopharm allows for the continued development of lunresertib, a novel PKMYT1 inhibitor, that has demonstrated encouraging results across multiple clinical trials in difficult-to-treat solid tumors. This agreement builds upon the success of Repare and Debiopharm’s existing collaboration studying the combination of lunresertib and Debio 0123,” said Steve Forte, President, Chief Executive Officer and Chief Financial Officer of Repare. “Our recent business development efforts have continued to enable Repare to focus on the advancement of our clinical priorities and sustained value creation. We remain focused on two ongoing Phase 1 clinical trials with readouts expected in the second half of 2025: the LIONS trial evaluating our RP-1664 PLK4 inhibitor and the POLAR trial evaluating our RP-3467 Pol ATPase inhibitor.” Under the terms of the agreement, Repare will receive a $10M upfront payment, and is eligible to receive up to $257M in potential clinical, regulatory, commercial and sales milestones, including up to $5M in potential near-term payments, and single-digit royalties on global net sales. Repare and Debiopharm entered into a clinical study and collaboration agreement in January 2024 to explore the synergy between lunresertib and Debio 0123, a potential best-in-class, brain penetrant and highly selective WEE1 inhibitor. Debiopharm will assume sponsorship of the MYTHIC study and take over existing and future development activities related to lunresertib.
