PMV Pharmaceuticals Initial PC14586 Phase 1 Data Presented at ASCO Demonstrated Anti-Tumor Activity Across Multiple Solid Tumor Types With a p53 Y220C Mutation
- Overall response rate (ORR) of 32% (8/25) achieved in higher dose cohorts per RECIST v1.1
- Partial responses observed across six distinct tumor types
- Data featured as an oral presentation at ASCO; Company to host investor event via webcast today at
6:30 pm CDTto review data presented
The data were featured in an oral presentation at the 2022
- The most common treatment-emergent adverse events (>15%) included nausea, vomiting, AST increase, ALT increase, anemia, blood creatinine increase, and fatigue.
- The maximum tolerated dose (MTD) was reached at 1500 mg twice daily.
- Enrollment at doses below the MTD is ongoing to support the determination of a recommended Phase 2 dose.
- ORR assessed by investigators according to RECIST v1.1 was 32% (8/25) in patients receiving an initial total daily dose of 1150 mg and above. Of the 8 responding patients, 6 have confirmed partial responses and 2 have unconfirmed partial responses, pending confirmation.
- ORR was 24% (8/33) across all dose cohorts.
- Responses were observed across six distinct tumor types including breast, endometrial, prostate, pancreatic, ovarian, and small cell lung cancer.
- Best Response of stable disease or partial response was observed in 19/25 patients at doses ≥1150 mg (76%).
“These encouraging Phase 1 safety and preliminary efficacy data provide proof of concept for PC14586 as monotherapy to selectively reactivate p53 across multiple tumor types,” said

PYNNACLE is an open-label, multicenter Phase 1/2 clinical study assessing safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of PC14586 in patients with advanced solid tumors harboring a p53 Y220C mutation. A total of 41 patients were enrolled as of
PC14586 is a first-in-class, small molecule p53 reactivator designed to selectively bind to the crevice present in the p53 Y220C mutant protein, hence, restoring the wild-type, or normal, p53 protein structure and tumor-suppressing function. PC14586 is being developed for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation. Fast Track designation has been granted by the
