Key achievement for Repare Therapeutics after receipt of $40 million Roche payment
It earned the milestone payment from Roche for developing and commercializing camonsertib (RP-3500 or RG6526), an oral small molecule drug in Roche’s TAPISTRY trial under its worldwide license collaboration.
Tapistry is a phase 2, global, multicenter, open-label, multi-cohort clinical trial designed to evaluate the safety and efficacy of targeted therapies or immunotherapy in participants with unresectable, locally advanced or metastatic solid tumors determined to harbor specific oncogenic genomic alterations.
In October, Roche also enrolled the first patient in a camonsertib-based arm in its phase 1b/2 clinical Lung Morpheus trial of multiple immunotherapy-based treatment combinations in participants with metastatic non-small cell lung cancer. The trials are actively enrolling patients. In collaboration with Roche, Repare is continuing to conduct tumor specific expansions in the ATTACC trial to support future clinical development for camonsertib + PARP inhibitor combinations.
“This milestone is a key achievement for us, demonstrating Roche’s commitment to the global clinical development of camonsertib and highlighting their exploration of development opportunities for camonsertib across multiple tumor types and genetic alterations to maximize patient impact,” said Lloyd Segal, president and chief executive officer of Repare.
Synthetic lethality approach
Under the terms of its collaboration with Roche, Repare received a $125 million upfront payment in July 2022, as well as $13.6 million in additional payments, and is eligible to receive up to $1.2 billion in potential clinical, regulatory, commercial and sales milestone payments, and royalties on global net sales ranging from high-single-digits to high-teens.
The collaboration also provides Repare with the ability to opt-in to a 50/50 US co-development and profit share arrangement, including participation in US co-promotion if US regulatory approval is received. If Repare chooses to exercise its co-development and profit share option, it will continue to be eligible to receive certain clinical, regulatory, commercial and sales milestone payments, in addition to full ex-US royalties.
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, to selectively target those tumors in patients most likely to achieve clinical benefit from resulting product candidates.
Repare Therapeutics is a leading clinical-stage precision oncology company enabled by its proprietary synthetic lethality approach to the discovery and development of novel therapeutics. The company uses its genome-wide, CRISPR-enabled platform to systematically discover and develop highly targeted cancer therapies focused on genomic instability, including DNA damage repair.
