"We were very pleased to recently share updated Phase 1 data from our PYNNACLE clinical trial with the oncology community, demonstrating clinical efficacy and safety of PC14586 in heavily pretreated patients across multiple solid tumor types," said David Mack, Ph.D., President and Chief Executive Officer. "On the strength of the positive findings and guidance from the FDA, we selected the recommended Phase 2 dose and are aligned on the clinical and regulatory pathway for further development of PC14586. We look forward to initiating a registrational Phase 2 study in the first quarter of 2024."

Third Quarter 2023 and Recent Corporate Highlights:

•
Updated clinical results from the Phase 1 PYNNACLE study evaluating PC14586 were featured in a late-breaking poster at the 2023 AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) on October 12, 2023. Confirmed responses were observed in patients whose tumors were TP53 Y220C and KRAS wild-type in the efficacious dose range, in multiple tumor types including ovarian, breast, prostate, small-cell lung, and endometrial cancer. An overall response rate of 38% was achieved at the Recommended Phase 2 Dose (RP2D) of 2000 mg daily (6/16 evaluable patients) reflective of the planned Phase 2 patient population (TP53 Y220C and KRAS wild-type). The median duration of response was seven months. A copy of the poster can be found on the PMV corporate website here: View Source
•
The RP2D of 2000 mg once daily was selected based on overall safety, pharmacokinetics (PK), and efficacy in alignment with the U.S. Food and Drug Administration (FDA) at an End of Phase 1 meeting held in Q3 2023. PMV plans to initiate a registrational tumor-agnostic Phase 2 clinical trial in early 2024.
•
The PYNNACLE clinical trial results were also highlighted in a KOL webinar which included a presentation by Aparna Parikh, M.D, M.S., Director of the Global Cancer Care Program at Mass General Hospital Cancer Center. A copy of the webinar presentation can be accessed here: View Source
•
Ongoing enrollment in the combination arm of PYNNACLE evaluating PC14586 with KEYTRUDA (pembrolizumab). PMV and Merck entered into a collaboration in 2022 under the terms of which Merck is supplying KEYTRUDA for this study.

Exhibit 99.1

•
PMV Pharma ended the third quarter with $238.1 million in cash, cash equivalents, and marketable securities.
•
Net loss for the nine months ended September 30, 2023, was $53.2 million compared to $54.0 million for the nine months ended September 30, 2022.
•
Research and development (R&D) expenses were $42.5 million for the nine months ended September 30, 2023, compared to $37.0 million for the nine months ended September 30, 2022. The increase in R&D expenses was primarily related to increased headcount and clinical expenses to advance research on PC14586, the Company’s lead drug candidate.
•
General and administrative (G&A) expenses were $18.7 million for the nine months ended September 30, 2023, compared to $18.9 million for the nine months ended September 30, 2022. The decrease in G&A expenses was primarily due to facility-related costs now allocated to research as our new laboratory building in Princeton, New Jersey began operations.
