Repare Therapeutics reports ‘encouraging’ Phase 1 camonsertib combo data

Repare Therapeutics reported data highlighting the clinical benefits of camonsertib, a potential best-in-class oral small molecule ATR inhibitor, combined with palliative radiation for the treatment of metastatic tumors harboring an ataxia-telangiectasia-mutated mutation. These data from a clinical trial conducted in collaboration with investigators at Memorial-Sloan Kettering Cancer Center were presented at the American Society for Radiation Oncology annual meeting in Washington, DC by Nancy Lee, MD, FASTRO, Radiation Oncologist & Early Drug Development Specialist, Memorial Sloan Kettering Cancer Center and titled, “Genotypically-Selected Pan Cancer Trial of Camonsertib with Palliative Radiation in the Treatment of Metastatic Tumors Harboring an Ataxia-Telangiectasia Mutated Mutation.” “These encouraging early Phase 1 data build further support for the broad clinical potential of camonsertib,” said Maria Koehler, MD, PhD, Executive Vice President and Chief Medical Officer of Repare. “This first-in-human study combining camonsertib, an ATR inhibitor, with palliative radiation provides early clinical data showing that the combination has the potential to radiosensitize for higher clinical benefit in patients with tumors harboring pathogenic ATM mutations versus those with variants of unknown significance. We are highly encouraged by this early look at the response rate and safety profile of this combination in the Phase 1 setting.”
