First Quarter 2021 Financial Results

• PMV Pharma ended the fourth quarter with $348.4 million in cash, cash equivalents, and marketable securities, compared to $361.4 million as of December 31, 2020. Net cash used in operations was $12.9 million for the three months ended March 31, 2021 compared to $8.1 million for the three months ended March 31, 2020.
• Net loss for the quarter ended March 31, 2021 was $11.6 million compared to $7.3 million for the quarter ended March 31, 2020.
• Research and development (R&D) expenses were $7.5 million for the three months ended March 31, 2021 compared to $6.0 million for the three months ended March 31, 2020. The increase in R&D expenses was primarily related to increased headcount and clinical expenses for advancing development of PC14586, the Company’s lead drug candidate.
• General and administrative (G&A) expenses were $4.2 million for the three months ended March 31, 2021, compared to $1.7 million for the three months ended March 31, 2020. The increase in G&A expenses was primarily due to expanding the infrastructure necessary for operating as a public company.

About p53

p53 plays a pivotal role in preventing abnormal cells from becoming a tumor by inducing programmed cell death. Mutant p53 takes on oncogenic properties that endow cancer cells with a growth advantage and resistance to anti-cancer therapy. The p53 Y220C mutation is associated with many cancers, including but not limited to breast, non-small cell lung cancer, colorectal, pancreatic, and ovarian cancers.

About PC14586

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 the p53 Y220C mutation and has been granted Fast Track designation by the U.S. FDA.
