The Evaluation of PC14586 in Patients With Advanced Solid Tumors Harboring a TP53 Y220C Mutation (PYNNACLE)

Description

PC14586 (INN: rezatapopt) is a first-in-class, oral, small molecule p53 reactivator that is selective for the TP53 Y220C mutation.

The primary objective of Phase 2 Monotherapy is to evaluate the efficacy of PC14586 (INN: rezatapopt) at the Recommended Phase 2 Dose (RP2D) including the Overall Response Rate (ORR) in the Ovarian Cancer Cohort and the ORR across all cohorts as determined by blinded independent central review. Secondary objectives of Phase 2 are to characterize the safety, pharmacokinetic (PK) properties, quality of life, and other efficacy measures of PC14586 (INN: rezatapopt) at the RP2D. Enrollment is open for the Phase 2 Monotherapy portion of the study.

The primary objective of Phase 1 Monotherapy is to establish the maximum tolerated dose (MTD) and RP2D of PC14586 (INN: rezatapopt). Secondary objectives are to characterize the PK properties, safety and tolerability, and to assess preliminary efficacy including ORR. Enrollment into Phase 1 Monotherapy is complete.

The primary objective of Phase 1b Combination Therapy is to establish the MTD/RP2D of PC14586 (INN: rezatapopt) when administered in combination with pembrolizumab. Secondary objectives of Phase 1b Combination Therapy are to characterize PK, safety and tolerability, and to assess preliminary efficacy of PC14586 (INN: rezatapopt) when administered in combination with pembrolizumab, including ORR. Enrollment into Phase 1b Combination Therapy is complete.
