- Enrollment on track in Phase 2 portion of PYNNACLE clinical trial evaluating rezatapopt as monotherapy in patients with TP53 Y220C and KRAS wild-type advanced solid tumors; more than 60% of sites activated across the U.S., Europe, and Asia-Pacific; interim analysis from Phase 2 monotherapy expected by mid-2025
- Eligibility criteria in ongoing Phase 1b rezatapopt and pembrolizumab combination arm of PYNNACLE trial adjusted to align with Phase 2 TP53 Y220C and KRAS wild-type patient population
- Cash, cash equivalents, and marketable securities of $212.9 million as of June 30, 2024, providing expected cash runway to end of 2026
PRINCETON, N.J., Aug. 08, 2024 (GLOBE NEWSWIRE) -- PMV Pharmaceuticals, Inc. (Nasdaq: PMVP), a precision oncology company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53, today reported financial results for the second quarter ended June 30, 2024, and provided an update on the Phase 2 monotherapy and Phase 1b combination portions of the PYNNACLE clinical trial.
“We are encouraged by the pace of site activation and patient enrollment in the Phase 2 PYNNACLE trial,” said David Mack, Ph.D., President and Chief Executive Officer of PMV Pharma. “I would like to thank our team for their continued execution, and we look forward to providing an update on the PYNNACLE clinical trial next year.”
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 will assess 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 of the trial 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 60% of sites activated across the U.S., Europe, and Asia-Pacific. PMV plans to provide data from the interim analysis of the Phase 2 monotherapy portion of the PYNNACLE trial by mid-2025 and anticipates a New Drug Application (NDA) filing by the end of 2026.
PYNNACLE Phase 1b Rezatapopt/Pembrolizumab Combination Update
Enrollment continues in the Phase 1b combination arm of the PYNNACLE trial evaluating rezatapopt in combination with pembrolizumab (200 mg every three weeks) in patients with advanced solid tumors harboring a TP53 Y220C mutation.
- Eight patients were initially enrolled at a dose of 1000 mg once-daily of rezatapopt and pembrolizumab. Three patients experienced a dose-limiting toxicity (DLT). Subsequently, per protocol, eight patients were enrolled at 500 mg once-daily rezatapopt and pembrolizumab. As no DLTs were observed at this dose level, the Safety Review Committee escalated the rezatapopt dose to 1000 mg once-daily. Enrollment is currently ongoing at this dose level for rezatapopt. The pembrolizumab dose has remained at 200 mg every three weeks throughout the course of the Phase 1b combination clinical trial. Further characterization to identify the optimal combination dose is in progress.
- The safety profile of the rezatapopt and pembrolizumab combination has been consistent with either agent as monotherapy.
- Based on a preliminary review of the Phase 1b combination data, KRAS wild-type patients experienced more of a clinical benefit compared to patients with a KRAS single-nucleotide variant (SNV). As a result, PMV has decided to exclude patients with a KRAS SNV from the Phase 1b combination arm in order to maximize the opportunity for patients to benefit from rezatapopt in combination with pembrolizumab. This exclusion criterion is aligned with the Phase 2 monotherapy portion of the PYNNACLE clinical trial.
Second Quarter 2024 Financial Results
PMV Pharma ended the second quarter with $212.9 million in cash, cash equivalents, and marketable securities, compared to $213.1 million as of March 31, 2024. Net cash used in operations was $17.8 million for the six months ended June 30, 2024, compared to $27.9 million for the six months ended June 30, 2023.
- Net loss for the quarter ended June 30, 2024, was $1.2 million compared to $17.4 million for the quarter ended June 30, 2023. The net loss reduction was a result of the company’s sale of its New Jersey accumulated net operating losses, with a corresponding $16.2 million income tax benefit.
- Research and development (R&D) expenses were $14.6 million for the quarter ended June 30, 2024, compared to $13.8 million for the quarter ended June 30, 2023. The increase in R&D expenses was primarily related to increased contractual research organization costs.
- General and administrative (G&A) expenses were $5.5 million for the quarter ended June 30, 2024, compared to $6.3 million for the quarter ended June 30, 2023. The decrease in G&A expenses was primarily due to reduced 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 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, 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.
In addition, rezatapopt in combination with pembrolizumab is being evaluated in the Phase 1b portion of the Phase 1/2 PYNNACLE trial. The primary objective of the Phase 1b portion of the trial is to determine the maximum tolerated dose and RP2D of rezatapopt when administered with pembrolizumab.
