Core Insights - The PEAK trial is the first study to show statistical significance over an active comparator in GIST patients, with the combination of bezuclastinib and sunitinib achieving a median progression-free survival (mPFS) of 16.5 months and an overall response rate (ORR) of 46% in patients previously treated with imatinib [1][2] Group 1: FDA Approval and Clinical Trial Results - The FDA has accepted Cogent Biosciences' New Drug Application (NDA) for bezuclastinib in combination with sunitinib for GIST patients who have received prior treatment with imatinib under the Real-Time Oncology Review (RTOR) program [1][4] - The bezuclastinib combination demonstrated a 50% reduction in the risk of disease progression or death compared to the current standard of care, with a hazard ratio of 0.50 (95% CI: 0.39 – 0.65) [2] - The mPFS for the bezuclastinib combination was 16.5 months compared to 9.2 months for sunitinib monotherapy, and the ORR was 46% for the bezuclastinib combination versus 26% for sunitinib [2] Group 2: Future Plans and Trials - Cogent is expected to initiate the RTOR process immediately, with the completion of the NDA submission anticipated in April 2026 [1][4] - Full results from the PEAK trial will be presented at a major medical meeting in the first half of 2026 [5] - A Phase 2 trial is expected to begin in mid-2026 to investigate the benefit of the bezuclastinib combination for first-line GIST patients with exon 9 mutations who are naive to or have recently started treatment with imatinib [5] Group 3: Company Overview - Cogent Biosciences is focused on developing precision therapies for genetically defined diseases, with bezuclastinib being a selective tyrosine kinase inhibitor targeting the KIT D816V mutation and other mutations in KIT exon 17 [6] - The company is also developing a portfolio of novel targeted therapies aimed at various mutations, including FGFR2/3, ErbB2, PI3Kα, KRAS, and JAK2 [6]
