Evaluating strategic alternatives to maximize shareholder value

Initial data for LIONS and POLAR trials expected to be reported in Q4 2025

$109.5 million in cash and cash equivalents and marketable securities

CAMBRIDGE, Mass. & MONTREAL--(BUSINESS WIRE)--Aug. 8, 2025-- Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a clinical-stage precision oncology company, today reported financial results for the second quarter ended June 30, 2025.

“We remain focused on exploring strategic alternatives and partnerships across our portfolio to enhance long-term shareholder value, as exemplified by our recent worldwide licensing agreement with Debiopharm for lunresertib and out-licensing of early-stage discovery platforms to DCx,” said Steve Forte, President, Chief Executive Officer and Chief Financial Officer of Repare. “In parallel to evaluating these strategic opportunities for our remaining programs, we expect to deliver initial data from the LIONS and POLAR trials in the fourth quarter.”

Second Quarter 2025 and Recent Portfolio Highlights:

• Entered into a worldwide licensing agreement with Debiopharm for lunresertib
  • In July 2025, Repare entered into an exclusive worldwide licensing agreement with Debiopharm International S.A. (“Debiopharm”) for lunresertib, a first-in-class precision oncology PKMYT1 inhibitor. Under the terms of the agreement, Repare will receive a $10 million upfront payment, and is eligible to receive up to $257 million in potential clinical, regulatory, commercial and sales milestones, including up to $5 million in potential near-term payments, and single-digit royalties on global net sales. This agreement builds on the success of Repare and Debiopharm's clinical study and collaboration agreement 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.

• Announced out-licensing of its discovery platforms to DCx Biotherapeutics
  • In May 2025, Repare out-licensed its early-stage discovery platforms, including certain platform and program intellectual property, to DCx Biotherapeutics Corporation (“DCx”), a newly-launched Canadian biotechnology company developing next generation precision drug conjugates supported by Amplitude Ventures. In connection with this agreement, Repare received a $1 million upfront payment and is expected to receive $3 million in near-term payments. In addition, Repare received a 9.99% equity position in DCx, including certain dilution protection rights, and is eligible to receive potential future out-licensing, clinical and commercial milestone payments, as well as low single-digit sales royalties for the development of certain products by DCx. In connection with this transaction, Repare recognized a $5.7 million gain during the quarter.

• RP-3467: Potential best-in-class, oral Polθ ATPase/helicase inhibitor
  • Repare is conducting a Phase 1 clinical trial of RP-3467 (POLAR), dosing patients alone and in combination with the poly-ADP ribose polymerase (PARP) inhibitor, olaparib. POLAR is a multicenter, open-label, dose-escalation Phase 1 clinical trial designed to investigate the safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of RP-3647 alone or in combination with olaparib in adults with locally advanced or metastatic epithelial ovarian cancer, metastatic breast cancer, metastatic castration-resistant prostate cancer, or pancreatic adenocarcinoma.
  • Upcoming expected milestone:
    • Q4 2025: Topline safety, tolerability and early efficacy data from the POLAR trial in monotherapy and in combination with olaparib.

• RP-1664: First-in-class, oral selective PLK4 Inhibitor
  • Repare completed enrolment of 29 patients in its Phase 1 LIONS clinical trial, evaluating RP-1664 as a monotherapy in adult and adolescent patients with TRIM37-high solid tumors. LIONS is a first-in-human, multicenter, open-label Phase 1 clinical trial designed to investigate safety, pharmacokinetics, pharmacodynamics and the preliminary efficacy of RP-1664.
  • Upcoming expected milestone:
    • Q4 2025: Initial topline safety, tolerability and early efficacy data from the LIONS trial.

• Amended our collaboration and license agreement with Bristol-Myers Squibb Company to include an additional druggable target in the collaboration
  • Repare recognized $0.3 million during the quarter as revenue related to druggable targets, reflecting this option fee payment.
• Exploring strategic alternatives to maximize shareholder value
  • Repare continues to actively explore strategic alternatives, partnerships and sale opportunities across its portfolio to maximize shareholder value.
