CAMBRIDGE, Mass. & MONTREAL - Repare Therapeutics Inc. (NASDAQ:RPTX), a precision oncology company, has announced positive initial data from its MINOTAUR Phase 1 clinical trial of lunresertib in combination with FOLFIRI for the treatment of advanced solid tumors. These findings were presented at the ESMO Gastrointestinal Cancers Congress 2024 in Munich, Germany, on June 26-29.
The trial, which involves patients with gastrointestinal tumors including those with colorectal cancer (CRC), has shown an overall response rate of 18.2% across all participants, with a clinical benefit rate of 51.5%. Particularly noteworthy is the response in CRC patients, where 40% of those who had not previously been treated with irinotecan experienced prolonged treatment durations exceeding nine months.
Lunresertib, a PKMYT1 inhibitor, targets specific genetic alterations such as CCNE1 amplification and FBXW7 mutations. The early data indicates that the drug, when combined with FOLFIRI, is well tolerated and could offer a new treatment option for patients with few approved alternatives.
The safety profile of the lunresertib and FOLFIRI combination was consistent with the known effects of FOLFIRI alone, with no treatment discontinuations due to safety concerns at the preliminary recommended Phase 2 dose (RP2D) of 60mg BID lunresertib. The most common Grade 3/4 treatment-related adverse events were neutropenia and leukopenia, which were reversible with treatment interruption.
Maria Koehler, MD, PhD, Chief Medical Officer of Repare, underscored the encouraging tolerability and early efficacy data, suggesting that further development in a randomized Phase 2 study is warranted. The company aims to address the unmet medical needs of patients with gastrointestinal tumors associated with poor prognosis.
Repare Therapeutics is engaged in the discovery and development of novel therapeutics based on its proprietary synthetic lethality approach. The company's pipeline includes multiple clinical and preclinical programs targeting genomic instability and DNA damage repair.

The expansion comes after encouraging results from ongoing trials with camonsertib, a therapy candidate that demonstrated extended progression-free survival in patients with ATM-mutated NSCLC. The trial aims to enroll up to 20 patients to evaluate the efficacy of camonsertib at the recommended Phase 2 dose, with data anticipated in 2025.
The U.S. Food and Drug Administration (FDA) has also granted Fast Track designation to Repare Therapeutics' ovarian cancer drug combination, lunresertib and camonsertib. This designation is intended to expedite the development and review of treatments for serious conditions, specifically for adult patients with certain genetic alterations in platinum-resistant ovarian cancer. The company is conducting a Phase 1 dose expansion trial of this drug combination, with results expected by the end of 2024.

Stein will join the board following the annual meeting of shareholders in June 2024, replacing Todd Foley, who will be stepping down.
