About the PYNNACLE Clinical Trial
The ongoing Phase 1/2 PYNNACLE study is evaluating PC14586 in patients with advanced solid tumors harboring a p53 Y220C mutation. The primary objective of the Phase 1 portion of the trial is to determine the maximum tolerated dose (MTD), and recommended Phase 2 dose of PC14586 when administered orally to patients. Safety, tolerability, pharmacokinetics and effects on biomarkers will also be assessed. Phase 2 will be an expansion study with the primary objective of evaluating the efficacy of PC14586 at the Recommended Phase 2 Dose (RP2D) in patients with TP53 Y220C advanced solid tumors. For more information about the Phase 1/2 PYNNACLE clinical trial, refer to www.clinicaltrials.gov (NCT study identifier NCT04585750).

About PC14586
PC14586 is a first-in-class, small molecule, p53 reactivator designed to selectively bind to the pocket present in the p53 Y220C mutant protein, hence, restoring the wild-type, or normal, p53 protein structure and tumor-suppressing function. The U.S. Food and Drug Administration (FDA) granted Fast Track designation to PC14586 for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation.
