• Rezatapopt, a first-in-class p53 Y220C reactivator, targets the once 'undruggable' p53 Y220C mutation, prevalent in about 1% of all cancers, offering a tumor-agnostic approach.
• Phase 1 data from the PYNNACLE study demonstrated an overall response rate of 34% in efficacy-evaluable patients treated with rezatapopt monotherapy across various advanced solid tumors.
• The agent exhibited a favorable safety profile, with mostly grade 1 or 2 treatment-related adverse events, and manageable gastrointestinal toxicities when administered with food.
• Phase 2 of the PYNNACLE study is underway, evaluating rezatapopt in specific cancer cohorts, with potential for accelerated approval based on promising initial results.
