Exploring strategic alternatives to advance clinical stage pipeline and maximize shareholder value

$124.2 million in cash and cash equivalents and marketable securities provides runway as of March 31, 2025

CAMBRIDGE, Mass. & MONTREAL--(BUSINESS WIRE)--May 13, 2025-- Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a clinical-stage precision oncology company, today reported financial results for the first quarter ended March 31, 2025.

“During the first quarter of 2025 we continued our efforts to create long-term value for our shareholders via partnering and by advancing our novel pipeline programs,” said Steve Forte, President, Chief Executive Officer and Chief Financial Officer of Repare. “We announced a strategic partnership with DCx Biotherapeutics to out-license our discovery platforms, and we are exploring a full range of strategic alternatives and partnerships across our portfolio. We are well-positioned from an operational and financial standpoint to drive our clinical pipeline to key inflection points and remain on track to report initial data for both the LIONS and POLAR trials in the second half of this year.”

First Quarter 2025 and Recent Portfolio Highlights:

• Announced out-licensing of its discovery platforms to DCx Biotherapeutics
  • Repare announced it out-licensed its early-stage discovery platforms, including certain platform and program intellectual property, to DCx Biotherapeutics Corporation (“DCx”). In connection with this agreement, Repare will receive upfront and near-term payments totaling $4 million, as well as 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. Additionally, DCx will retain approximately 20 of Repare’s preclinical research employees.

• 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:
    • Q3 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

• Lunresertib (RP-6306)
  • Repare is currently evaluating lunresertib in combination with Debio 0123, a highly selective, brain-penetrant, clinical WEE1 inhibitor, in patients with advanced solid tumors harboring CCNE1 amplification or FBXW7 or PPP2R1A deleterious alterations as part of an ongoing 50/50 cost sharing collaboration with Debiopharm. Repare does not intend to continue to develop lunresertib in any other trials, absent securing a partnership with a development partner.

First Quarter 2025 Financial Results

• Cash, cash equivalents and marketable securities: Cash, cash equivalents and marketable securities as of March 31, 2025 were $124.2 million, as compared to $152.8 million as of December 31, 2024. The Company believes that its cash, cash equivalents, and marketable securities are sufficient to fund its current operational plans through 2027.
• Revenue from collaboration agreements: Revenue from collaboration agreements was nil and $52.4 million for the three months ended March 31, 2025 and 2024, respectively.
• Research and development expense, net of tax credits (Net R&D): Net R&D expenses were $20.3 million and $33.0 million for the three months ended March 31, 2025 and 2024, respectively.
• General and administrative (G&D) expenses: G&A expenses were $7.7 million and $8.6 million for the three months ended March 31, 2025 and 2024, respectively.
• Net income (loss): Net loss was $30.1 million, or $0.71 per diluted share, and $13.2 million, or $0.30 per diluted share, for the three months ended March 31, 2025 and 2024, respectively.
