A Study to Investigate the Effects of Acid Reducing Agents on Pharmacokinetics of PC14586 in Healthy Participants

PMV Pharmaceuticals, Inc28 enrolled

Overview

This study will assess the effect of a Proton Pump Inhibitor (PPI) (rabeprazole) on the pharmacokinetics (PK) of PC14586 and the effect of an H2-receptor antagonist (famotidine) on the PK of PC14586

PC14586 is a first-in-class, oral, small molecule p53 reactivator that is selective for the TP53 Y220C mutation. This study will investigate the effects of acid reducing agents on the pharmacokinetics of PC14586. This is a 2-part, open-label, two-period, fixed-sequence study in healthy participants with each participant used as his/her own control to assess the effect of rabeprazole (Part 1) or famotidine (Part 2) on the PK of PC14586. The results from Part 1 will be analyzed before deciding to, if applicable, progress to Part 2. Part 2 of the study will only be initiated if the findings from Part 1 show an interaction or are inconclusive. Approximately 25 participants will be enrolled in Part 1 and approximately 25 participants will be enrolled in Part 2. The Study timelines reflect both Part 1 and Part 2.
