PMV Pharma plans to provide interim analysis data from the Phase 2 PYNNACLE trial in the middle of 2025. This interim analysis will include data for approximately 50 patients, of which approximately 40% are in the ovarian cancer cohort, who have been followed for at least 18 weeks.
"Our registrational PYNNACLE trial continues to progress well and enrollment remains on track," said David Mack, Ph.D., President and Chief Executive Officer of PMV Pharma. "I am very appreciative of the efforts of our team and their continued execution. We look forward to providing data from the interim analysis in the middle of this year."

First Quarter 2025 Financial Results
PMV Pharma ended the first quarter with $165.8 million in cash, cash equivalents, and marketable securities, compared to $183.3 million as of December 31, 2024.

•
Research and development (R&D) expenses were $17.4 million for the quarter ended March 31, 2025, compared to $13.2 million for the quarter ended March 31, 2024. The increase in R&D expenses was primarily due to external expenses related to the advancement of product candidates, offset by decreased personnel related costs and stock-based compensation.
•
General and administrative (G&A) expenses were $4.1 million for the quarter ended March 31, 2025, compared to $5.0 million for the quarter ended March 31, 2024. The decrease in G&A expenses was primarily due to reduced headcount and spend for facility and operational expenses.
About Rezatapopt
Rezatapopt (PC14586) is a first-in-class, small molecule, p53 reactivator designed to selectively bind to the pocket in the p53 Y220C mutant protein, restoring the wild-type tumor-suppressor function. The U.S. Food and Drug Administration (FDA) granted Fast Track designation to rezatapopt for the treatment of patients with locally advanced or metastatic solid tumors with a p53 Y220C mutation.
About the PYNNACLE Clinical Trial
The ongoing Phase 1/2 PYNNACLE clinical trial is evaluating rezatapopt in patients with advanced solid tumors harboring a TP53 Y220C mutation. The primary objective of the Phase 1 portion of the trial was to determine the maximum tolerated dose and recommended Phase 2 dose (RP2D) of rezatapopt when administered orally to patients. Safety, tolerability, pharmacokinetics and effects on biomarkers were also assessed. The Phase 2 portion is a registrational, single arm, expansion basket clinical trial comprising five cohorts (ovarian, lung, breast, and endometrial cancers, and other solid tumors) with the primary objective of evaluating the efficacy of rezatapopt at the RP2D in patients with TP53 Y220C and KRAS wild-type advanced solid tumors.
