PRINCETON, N.J., March 03, 2025 (GLOBE NEWSWIRE) -- PMV Pharmaceuticals, Inc. (Nasdaq: PMVP), a precision oncology clinical-stage company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53, today reported financial results for the full year ended December 31, 2024, and provided a corporate update.

“PMV demonstrated excellent execution in 2024 with the continued advancement of the pivotal, Phase 2 portion of the PYNNACLE trial, and we look forward to providing data from an interim analysis in the middle of this year,” said David Mack, Ph.D., President and Chief Executive Officer of PMV Pharma. “We continue to explore additional settings where rezatapopt may have utility and are pleased to have recently started enrolling patients in an investigator-led Phase 1b study in patients with relapsed/refractory acute myeloid leukemia or myelodysplastic syndrome harboring a TP53 Y220C mutation.”

PYNNACLE Phase 2 Monotherapy Update:

Enrollment is on track in the Phase 2 monotherapy portion of the PYNNACLE clinical trial. The multicenter, single-arm, registrational, tumor-agnostic Phase 2 trial is assessing rezatapopt as monotherapy at a dose of 2000 mg once-daily in patients with TP53 Y220C and KRAS wild-type advanced solid tumors. The primary endpoint is overall response rate per blinded independent central review. The trial is designed to enroll 114 patients across five cohorts at approximately 60 sites. Site activation is progressing well, with more than 90% of sites activated across the U.S., Europe, U.K., and Asia-Pacific. PMV Pharma plans to provide data from the interim analysis of the Phase 2 monotherapy portion of PYNNACLE in the middle of 2025 and anticipates a New Drug Application submission by the end of 2026.

Full Year 2024 and Recent Corporate Highlights:

• Announced a collaboration with MD Anderson Cancer Center and Memorial Sloan Kettering Cancer Center to support an investigator-initiated Phase 1b study in approximately 25 patients with relapsed or refractory acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) harboring a TP53 Y220C mutation. The study is designed to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of rezatapopt monotherapy and in combination with azacitidine within this high unmet medical need patient population. Enrollment in the study has commenced.

• PYNNACLE Phase 1 data of rezatapopt in advanced ovarian cancer patients featured in a late-breaking oral presentation at the 2024 Society for Gynecologic Oncology Annual Meeting on Women’s Cancer. Of the 15 patients in the efficacy evaluable population, seven patients achieved a confirmed partial response (PR) with a seven-month median duration of response and a favorable safety profile.

• PYNNACLE Phase 1 data of rezatapopt in advanced breast cancer patients featured in a poster presentation at the 2024 San Antonio Breast Cancer Symposium. Of the eight patients in the efficacy evaluable population, three patients achieved a confirmed PR with a favorable safety profile.

• Rezatapopt food-effect data were presented during a poster session at the 2024 American College of Clinical Pharmacology Annual Conference.

• Paper published in ACS Medicinal Chemistry Letters describing the discovery of rezatapopt. The paper titled, “Discovery of Rezatapopt (PC14586), a First-in-Class, Small-Molecule Reactivator of p53 Y220C Mutant in Development” can be accessed here.

• Announced a partnership with Foundation Medicine to develop FoundationOne^®CDx, a tissue-based comprehensive genomic profiling test as a companion diagnostic for rezatapopt.

• Discontinued enrollment in the combination arm of the Phase 1b PYNNACLE trial evaluating rezatapopt and Merck’s anti-PD-1 therapy KEYTRUDA^® (pembrolizumab). At the maximum tolerated dose of rezatapopt 500 mg once-daily in combination with pembrolizumab 200 mg every three weeks, patients did not experience a clinically meaningful benefit, informing the decision to discontinue enrollment in the combination arm.

Fiscal Year 2024 Financial Results

• As of December 31, 2024, PMV Pharma had $183.3 million in cash, cash equivalents, and marketable securities, compared to $228.6 million at December 31, 2023. Net cash used in operations was $51.3 million for the year ended December 31, 2024, compared to $55.7 million for the year ended December 31, 2023.

• Net loss for the year ended December 31, 2024, was $58.7 million compared to $69.0 million for the year ended December 31, 2023.

• Research and development (R&D) expenses were $58.5 million for the year ended December 31, 2024, compared to $55.9 million for the year ended December 31, 2023. The increase in R&D expenses was primarily related to clinical expenses for advancing rezatapopt, the Company’s lead drug candidate.

• General and administrative (G&A) expenses were $26.9 million for the year ended December 31, 2024, compared to $24.2 million for the year ended December 31, 2023. The increase in G&A expenses was primarily due to facility-related costs for the relocation of the Company's lab and office space, offset by reductions in headcount.

KEYTRUDA^® (pembrolizumab) is a registered trademark of Merck Sharp & Dohme LLC., a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

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 TP53 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. In Phase 1, an overall response rate of 38% (6/16 evaluable patients) was achieved at the RP2D of 2000 mg daily reflective of the Phase 2 patient population (TP53 Y220C and KRAS wild-type). The median duration of response was seven months. The Phase 2 monotherapy portion is a registrational, single-arm, expansion basket clinical trial comprising five cohorts (ovarian, lung, breast, 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.
