Repare will regain control of its potential best-in-class oral small molecule ATR inhibitor
CAMBRIDGE, Mass. & MONTREAL--(BUSINESS WIRE)--Feb. 12, 2024--
Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a leading clinical-stage precision oncology company, announced today that it will regain global development and commercialization rights to camonsertib (RP-3500), a potential best-in-class oral small molecule inhibitor of ATR (Ataxia-Telangiectasia and Rad3-related protein kinase), following termination of its collaboration agreement with Roche.
Roche notified Repare that, effective May 7, 2024, it is terminating its worldwide license and collaboration agreement for the development and commercialization of camonsertib following a review of Roche’s pipeline and evolving external factors. Repare regains full control of all rights for camonsertib, a potential best-in-class inhibitor of ATR.
“Camonsertib is a valuable, high-potential precision oncology medicine that has achieved clinical proof-of-concept in multiple tumor types and genotypes both as monotherapy and in combination, as previously reported. We have been continuously running clinical trials for camonsertib since July 2020 and are excited to steward the progress of this promising therapy,” said Lloyd M. Segal, President and Chief Executive Officer of Repare. “While we are disappointed to end this collaboration, we appreciate the contributions Roche has made to the program. With the return of camonsertib, Repare’s deep clinical pipeline consists of four wholly-owned synthetic lethal therapies.”
Camonsertib is also part of Repare’s ongoing Phase 1 MYTHIC trial evaluating the combination of camonsertib and lunresertib, a first-in-class, oral small molecule inhibitor of PKMYT1, in patients with molecularly selected, advanced solid tumors. In October 2023, Repare presented data on the camonsertib and lunresertib combination, demonstrating clear evidence of clinical benefit across multiple tumor types and all selected genotypes, with an overall response of 33.3% across all tumor types and 50% RECIST objective response in patients with heavily pre-treated gynecologic tumors at the preliminary recommended Phase 2 dose of the combination. Repare expects to report additional camonsertib and lunresertib combination therapy data from the expansion cohorts of this trial in the second half of 2024.
Repare has met all obligations under the Roche agreement to date, and recently earned a $40 million milestone payment from Roche. Repare continues to expect that its existing cash, cash equivalents, and marketable securities will provide sufficient capital to fund planned operations into mid-2026.
About Repare Therapeutics’ SNIPRx® Platform
Repare’s SNIPRx® platform is a genome-wide CRISPR-based screening approach that utilizes proprietary isogenic cell lines to identify novel and known synthetic lethal gene pairs and the corresponding patients who are most likely to benefit from the Company’s therapies based on the genetic profile of their tumors. Repare’s platform enables the development of precision therapeutics in patients whose tumors contain one or more genomic alterations identified by SNIPRx® screening, in order to selectively target those tumors in patients most likely to achieve clinical benefit from resulting product candidates.
