Repare Therapeutics Provides Business and Clinical Update and Reports First Quarter 2024 Financial Results

Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a leading clinical-stage precision oncology company, today reported financial results for the first quarter ended March 31, 2024.

“This was a quarter of clinical progress as we await key, near-term data on a rich set of distinctive clinical approaches for our four wholly-owned compounds in 2024,” said Lloyd M. Segal, President and Chief Executive Officer of Repare. “We have agreement with the FDA regarding our recommended Phase 2 dose (RP2D) for our lunresertib plus camonsertib combination, with significantly improved tolerability at the RP2D with our updated dosing schedule. We are seeing continuing trends of patient response and benefit, and we are on track to report the updated dataset in the fourth quarter of 2024. Our objective is to determine the best opportunity for a registrational trial, to start in 2025. Additionally, we are initiating a small clinical trial to rapidly confirm a camonsertib monotherapy signal in non-small cell lung cancer (NSCLC) and expect that readout to be available in 2025. Our clinical portfolio also includes the LIONS trial of our RP-1664 PLK4 inhibitor, the PKMYT1 and WEE1 inhibitor combination in MYTHIC, and the upcoming clinical start of our Polθ inhibitor program, RP-3467, in the second half of 2024.”

First Quarter 2024 and Recent Portfolio Highlights:

• Lunresertib (RP-6306)
  • On track for a potential registrational trial decision in gynecologic expansion cohorts in the fourth quarter of 2024 based on the Phase 1 expansion in MYTHIC trial evaluating lunresertib in combination with camonsertib in patients harboring CCNE1 amplification or FBXW7 or PPP2R1A deleterious alterations. Grade 3 anemia has been significantly reduced to 25% as of the March 2024 cut-off date in patients treated at the RP2D and updated dosing schedule, from 45% as previously presented at the September 2023 data cut-off date. The U.S. Food and Drug Administration (FDA) has agreed with the RP2D of lunresertib 80mg BID and camonsertib 80mg QD. Efficacy and tolerability assessment at RP2D is ongoing, and the Company expects to present data from the dose expansion cohorts in patients with ovarian and endometrial cancer in the fourth quarter of 2024.
  • First patient was dosed in April 2024 in the Phase 1 MYTHIC clinical trial evaluating lunresertib in combination with Debio 0123, a highly selective, brain-penetrant, clinical WEE1 inhibitor, in advanced solid tumors harboring CCNE1 amplification or FBXW7 or PPP2R1a deleterious alterations. The primary endpoints are safety, tolerability and RP2D, as well as preliminary efficacy of the combination. Repare is expected to report initial data from this trial in 2025.
  • Initial data from the Phase 1 MINOTAUR trial evaluating lunresertib in combination with FOLFIRI for the treatment of advanced solid tumors demonstrated no significant incremental toxicities in the combination of lunresertib and FOLFIRI over FOLFIRI alone. In addition, Repare has observed favorable tolerability in colorectal and other gastrointestinal tumors, unlike some other agents combined with irinotecan. This data will be presented at the European Society of Medical Oncology (ESMO) Gastrointestinal (GI) Cancers Congress 2024, taking place in Munich, Germany on June 26-29.
• Camonsertib (RP-3500)
  • Regained global development and commercialization rights for camonsertib from Roche, effective May 7, 2024. Since inception of the Roche camonsertib collaboration, Repare has earned a cumulative total of $182.6 million from Roche, including the upfront and milestone payments, in addition to certain additional reimbursements from Roche.
  • Initiating Phase 2 TRESR expansion in approximately 20 patients with ATM-mutated (ATMm) NSCLC, supported by early, promising camonsertib monotherapy signal in patients with ATMm NSCLC from the ongoing Phase 1/2 TRESR trial. Repare is expected to report initial data in 2025.
• RP-1664
  • First patient dosed in the multicenter, open-label Phase 1 dose escalation trial (LIONS) of its polo-like kinase 4 (PLK4) inhibitor, RP-1664, in adult and adolescent patients with TRIM37-high and other biomarkers in February 2024.
• RP-3467
  • Initiation of a Phase 1 dose finding trial of RP-3467, a potential best-in-class Polθ ATPase inhibitor, is expected in the second half of 2024.
• Other Highlights
  • In March 2024, Bristol-Myers Squibb exercised its one remaining option to in-license an undruggable target for a combined total of five druggable targets and one undruggable target over the course of the collaboration.
  • In April 2024, Repare announced the appointment of Steven H. Stein, M.D., Chief Medical Officer of Incyte Corporation, to Repare’s Board of Directors, effective as of June 17, 2024, the date of the Company's upcoming annual meeting of shareholders (the “Annual Meeting”). The Company also announced that Todd Foley has decided not to stand for re-election as a director of the Company following the end of his current term as a Class I director on the date of the Annual Meeting, after serving more than seven years on the Board.

Summary of Expected Milestones:

• H1 2024
  • Initial Phase 1 MINOTAUR (lunresertib + FOLFIRI combination) data to be reported at ESMO GI in June 2024
• H2 2024
  • Camonsertib monotherapy expansion to NSCLC in TRESR
  • Initiation of Phase 1 clinical trial of RP-3467
  • Additional data from dose expansion cohorts for the MYTHIC lunresertib + camonsertib combination in ovarian and endometrial cancers by end of Q4 2024
• 2025
  • Lunresertib + Debio 0123 combination data
  • Camonsertib monotherapy data in NSCLC
  • Initiate first pivotal trial in an indication for lunresertib + camonsertib

First Quarter 2024 Financial Results:

• Cash, cash equivalents and marketable securities: Cash, cash equivalents and marketable securities as of March 31, 2024 were $237.0 million, as compared to $223.6 million as of December 31, 2023. The Company believes that its cash, cash equivalents, and marketable securities are sufficient to fund its current operational plans at least into mid-2026.
• Revenue from collaboration agreements: Revenue from collaboration agreements was $52.4 million and $5.7 million for the three months ended March 31, 2024 and 2023, respectively. The increase in revenue for the three-month period was primarily due to the $40.0 million Roche milestone achievement in the first quarter of 2024.
• Research and development expenses, net of tax credits (Net R&D): Net R&D expenses were $33.0 million and $31.8 million for the three months ended March 31, 2024 and 2023, respectively. The increase in Net R&D for the three-month period was primarily due to higher direct external costs related to the progress of Repare’s lunresertib clinical program, offset by lower direct external costs of its camonsertib clinical program.
• General and administrative (G&A) expenses: G&A expenses were $8.6 million and $8.5 million for the three months ended March 31, 2024 and 2023, respectively.
• Net income (loss): Net income was $13.2 million, or $0.30 per diluted share, for the three months ended March 31, 2024, and net loss was $34.9 million, or $0.83 per diluted share, for the three months ended March 31, 2023.
