This study will assess the safety and tolerability of multiple dose levels of PC14586 in participants with advanced solid tumors containing a p53 Y220C mutation.

Official Title

A Phase 1/2 Open-label, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of PC14586 in Patients With Advanced Solid Tumors Harboring a p53 Y220C Mutation


PC14586 is a first-in-class, oral, small molecule p53 reactivator that is selective for the p53 Y220C mutation. The trial will be conducted in 2 parts: dose escalation (Phase 1) and dose expansion (Phase 2). The primary objective of Phase 1 is to establish the maximum tolerated dose / recommended dose of PC14586 to treat participants with advanced solid tumors harboring a p53 Y220C mutation. Secondary objectives of Phase 1 are to characterize the pharmacokinetic properties of the investigational drug, its safety and tolerability, and to assess the overall response rate (ORR). The primary objective of Phase 2 is to assess the ORR in participants with advanced solid tumors harboring a p53 Y220C mutation as determined by blinded independent central review. Secondary objectives of Phase 2 include the safety, pharmacokinetic properties, and efficacy of PC14586 at the recommended dose.
