CAMBRIDGE, Mass. & MONTREAL--(BUSINESS WIRE)--Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a leading clinical-stage precision oncology company, today reported financial results for the third quarter ended September 30, 2024.
“We look forward to reporting data from our MYTHIC dose expansion clinical trial evaluating lunresertib in combination with camonsertib at the recommended Phase 2 dose at a company event in December, with the plan to begin a registrational trial in 2025. This combination therapy has the potential to be a new treatment paradigm in genomically-defined platinum-resistant ovarian cancer and second-line endometrial cancer,” said Lloyd M. Segal, President and CEO of Repare. “In the third quarter, we continued to make progress across our pipeline, including the dosing of the first patient in the POLAR clinical trial evaluating RP-3467, alone and in combination with the PARP inhibitor, olaparib. Additionally, we presented first-in-human data highlighting the clinical benefits of camonsertib in combination with radiotherapy at the ASTRO annual meeting in collaboration with investigators at Memorial-Sloan Kettering Cancer Center.”
Third Quarter 2024 and Recent Portfolio Highlights:
- Lunresertib (RP-6306): First-in-class, oral PKMYT1 inhibitor
- Currently evaluating lunresertib in combination with camonsertib in Repare’s MYTHIC dose expansion clinical trial at the RP2D in patients with platinum-resistant ovarian and endometrial cancers harboring CCNE1 amplification or FBXW7 or PPP2R1A mutations, which are predictive of poor prognosis. Repare is on track to report data from approximately 20-30 patients in each cohort in December 2024, with the plan to begin a registrational trial in 2025.
- Presented positive updated safety and tolerability data from the Phase 1 MYTHIC trial at the RP2D highlighting the benefits of its individualized schedule for the management of anemia at the 36th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in October 2024. In this analysis, Repare followed patients for approximately nine months at the RP2D to assess the effectiveness of an individualized schedule. The analysis demonstrated a successful approach to mitigating mechanism-based anemia while maintaining clinical benefit. No thrombocytopenia of any grade nor serious neutropenia in these patients was observed. Dose optimization meaningfully reduced Grade 3 anemia to 22.6% from 51.4% in all patients.
- Presented data at the American Association of Cancer Research’s (AACR) 15th Annual Ovarian Cancer Research Symposium in September 2024 highlighting the impact of alterations in FBXW7, PPP2R1A and CCNE1 in patients with metastatic ovarian and endometrial cancers based on an analysis in approximately 2,000 patients from Cancer Genome Atlas Research Network and Memorial Sloan Kettering’s Metastatic Events and Tropisms. The data underscores inherent chemotherapy resistance and the lack of treatment options for metastatic gynecologic cancer patients with these biomarkers.
- Evaluating lunresertib in combination with Debio 0123, a highly selective, brain-penetrant, clinical WEE1 inhibitor, in Module 4 of the ongoing MYTHIC clinical trial in patients with advanced solid tumors harboring CCNE1 amplification or FBXW7 or PPP2R1A deleterious alterations. Repare expects to report initial data from Module 4 of the MYTHIC trial in 2025.
- Camonsertib (RP-3500): Potential best-in-class oral ATR inhibitor
- Evaluating camonsertib as a monotherapy in the ongoing non-small cell lung cancer (NSCLC) expansion of the Phase 2 TRESR clinical trial. Camonsertib has demonstrated a promising signal of prolonged progression free survival in patients with ATM-mutated NSCLC in the TRESR clinical trial. Repare expects to report initial data from the TRESR clinical trial in 2025.
- Presented Phase 1 data from a clinical trial conducted in collaboration with investigators at Memorial-Sloan Kettering Cancer Center highlighting camonsertib in combination with palliative radiation for the treatment of metastatic tumors harboring an ataxia-telangiectasia-mutated (ATM) mutation at the American Society for Radiation Oncology (ASTRO) annual meeting in September 2024. The first-in-human data showed that the combination demonstrated higher clinical benefit in patients with tumors harboring pathogenic ATM mutations versus those with variants of unknown significance.
- RP-1664: First-in-class, oral, selective PLK4 inhibitor
- Evaluating RP-1664 as a monotherapy in the Phase 1 LIONS clinical trial in adult and adolescent patients with TRIM37-high solid tumors, including the recent dosing of the first adolescent patient with neuroblastoma. After evaluating safety in the LIONS clinical trial, the Company expects to rapidly advance RP-1664 into a Phase 1/2 trial in pediatric patients with high risk, recurrent neuroblastoma, where the patients have a high prevalence of TRIM37-altered tumors.
- RP-3467: Potential best-in-class, oral Polθ ATPase inhibitor
- Dosed the first patient in the POLAR clinical trial evaluating RP-3467, a Polθ ATPase inhibitor, alone and in combination with the poly-ADP ribose polymerase (PARP) inhibitor, olaparib. The POLAR clinical trial is a multicenter, open-label, dose-escalation Phase 1 clinical trial to investigate the safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of RP-3647 alone or in combination with olaparib in adults with molecularly selected advanced solid tumors. The trial is expected to enroll patients with locally advanced or metastatic epithelial ovarian cancer, metastatic breast cancer, metastatic castration-resistant prostate cancer, or pancreatic adenocarcinoma.
- Other Company Updates
- In August 2024, Repare announced a strategic reprioritization of its research and development activities to focus its efforts on the advancement of its portfolio of clinical-stage oncology programs. As part of this strategic refocus, Repare reduced its overall workforce by approximately 25%, with a majority of the headcount reductions from its preclinical group.
Third Quarter 2024 Financial Results:
- Cash, cash equivalents and marketable securities: Cash, cash equivalents and marketable securities as of September 30, 2024 were $179.4 million.
