Cash, cash equivalents, and marketable securities of $93.5 million as of March 31, 2026 providing expected cash runway to end of second quarter of 2027

 

PRINCETON, N.J., May 12, 2026 (GLOBE NEWSWIRE) -- PMV Pharmaceuticals, Inc. (“PMV Pharma” or the “Company”; Nasdaq: PMVP), a precision oncology company pioneering the discovery and development of small molecule therapies targeting p53, today reported financial results for the first quarter ended March 31, 2026, and provided a corporate update.

 

“The first quarter was one of continued execution as we advance the PYNNACLE study and remain on track to target an NDA submission for rezatapopt for platinum‑resistant/refractory ovarian cancer in the first quarter of 2027,” said David Mack, Ph.D., President and Chief Executive Officer of PMV Pharma. “We are also encouraged by the publication of the PYNNACLE Phase 1 results in the New England Journal of Medicine, which underscores the scientific innovation behind rezatapopt and highlights its potential to address a significant unmet medical need. Patients with TP53 Y220C advanced solid tumors, including platinum resistant ovarian cancer, experience poor outcomes despite available therapies.”

 

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 Phase 2 study is assessing rezatapopt as monotherapy at a dose of 2000 mg once-daily in patients with TP53 Y220C advanced solid tumors.

 

PMV Pharma anticipates submitting a New Drug Application (NDA) for rezatapopt in platinum-resistant/refractory ovarian cancer patients with a TP53 Y220C mutation in the first quarter of 2027.

 

Corporate Highlights:

Updated Phase 2 PYNNACLE clinical results evaluating rezatapopt were featured in an oral presentation at the 2026 Society of Gynecologic Oncology Annual Meeting on Women's Cancer on April 12, 2026.
o
Confirmed responses were observed in platinum-resistant/refractory ovarian cancer patients with a TP53 Y220C mutation
Overall response rate (ORR) of 44% (32/72 patients) per investigator assessment according to Response Evaluation Criteria in Solid Tumors

(RECIST) version 1.1, including one confirmed complete response, 31 confirmed partial responses.
The median time to response was 1.3 months and the median duration of response was 8.2 months.
Post the March 29, 2026 data cutoff, two additional patients achieved unconfirmed partial responses (uPRs), bringing the ORR to 46% (34/74).

 

Phase 1 results from the ongoing Phase 1/2 PYNNACLE study were published in the New England Journal of Medicine, “Phase 1 Study of Rezatapopt, a p53 Reactivator, in TP53 Y220C-Mutated Tumors.” The manuscript highlighted that rezatapopt demonstrated antitumor activity in heavily pretreated patients across multiple solid tumor types which provided proof-of-concept for p53 reactivation. Clinical activity and biomarker data were consistent with selective binding to the Y220C pocket and restoration of wild-type p53 tumor suppressor function.

 

The U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation (ODD) to rezatapopt for the treatment of TP53 Y220C positive ovarian cancer, fallopian tube cancer, and primary peritoneal cancer. The FDA provides ODD status to drugs intended for the safe and effective treatment, diagnosis, or prevention of rare diseases that affect fewer than 200,000 people in the U.S. Benefits of the designation may include exemption from certain FDA fees, financial incentives for qualified clinical development, and seven years of market exclusivity in the U.S. if the treatment is approved.

 

First Quarter 2026 Financial Results

PMV Pharma ended the first quarter with $93.5 million in cash, cash equivalents, and marketable securities, compared to $112.9 million as of December 31, 2025. Net cash used in operations was $19.7 million for the three months ended March 31, 2026, compared to $18.3 million for the three months ended March 31, 2025.

Net loss for the quarter ended March 31, 2026, was $18 million compared to $17.4 million for the quarter ended March 31, 2025. The net loss increase was primarily due to the benefit received from the sale of NOL carryforwards in Q1 2025, offset by decreased research and development (R&D) costs.
R&D expenses were $15.3 million for the quarter ended March 31, 2026, compared to $17.4 million for the quarter ended March 31, 2025. The decrease in R&D expenses was primarily due to decreased contractual research organization costs for the advancement of the rezatapopt program.
General and administrative (G&A) expenses were $3.7 million for the quarter ended March 31, 2026, compared to $4.1 million for the quarter ended March 31, 2025. The decrease in G&A expenses was primarily due to reduced personnel expenses and a decrease in finance and legal support costs.

 

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 granted Fast Track designation to rezatapopt for the treatment of patients with locally advanced or metastatic solid tumors with a p53 Y220C

mutation and Orphan Drug Designation for the treatment of TP53 Y220C positive ovarian cancer, fallopian tube cancer, and primary peritoneal cancer.

 

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 clinical 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, conducted across approximately 70 sites.
