Foundation Medicine and PMV Pharma Partner to Develop Genomic Profiling for TP53 Mutation Therapy, Targets TP53 Mutation in Advanced Cancers with Investigational Therapy Rezatapopt

PMVP, &quot, PMV Pharma&quot, ))))) today announced a partnership to develop Foundation Medicine's tissue-based comprehensive genomic profiling test, FoundationOne®CDx, as a companion diagnostic for PMV Pharma's rezatapopt, a first-in-class, investigational therapy for patients with locally advanced or metastatic solid tumors that have a TP53 Y220C mutation.

Across all human cancers, TP53 is the most frequently altered gene, with mutations occurring in approximately 50% of cancer cases.1 Historically, TP53 mutations have been considered undruggable despite its prevalence across cancers.2 TP53 Y220C mutation is one of the most frequently observed TP53 mutations, occurring in approximately 1% of all solid tumors.3 PMV Pharma is developing rezatapopt, a small molecule, to reactivate the p53 function in an advanced cancer patient population harboring a TP53 Y220C mutation.
