Update from SABCS 2024: Rezatapopt in TP53 Y220C mutated mBC: PYNNACLE phase 1/2 update

In this conference update, Prof. Frédérique Penault-Llorca and Dr Ecaterina Dumbrava provide expert insights into the findings of the PYNNACLE phase 1/2 study presented at SABCS 2024. This study investigates rezatapopt as a monotherapy for patients with locally advanced or metastatic solid tumours harbouring a TP53 Y220C mutation, including those with metastatic breast cancer (mBC). In the video, the experts discuss: • The role of TP53 mutations in breast cancer and the significance of the TP53 Y220C variant • Efficacy and safety results of rezatapopt in patients with mBC harbouring the TP53 Y220C mutation • The importance of genomic testing for identifying the TP53 Y220C mutation • Potential implications for clinical practice and future perspectives Clinical Takeaways: • Reactivating wild-type p53 is a promising therapeutic strategy for breast cancers with TP53 mutations, particularly in TNBC, where effective targeted therapies and biomarkers are limited. • Rezatapopt (PC14586) is a first-in-class investigational p53 reactivator that selectively binds to the mutated p53 Y220C protein, stabilising its structure to restore wild-type tumour suppressor activity. • In a subgroup analysis of the Phase 1 portion of the PYNNACLE trial, rezatapopt demonstrated encouraging preliminary efficacy safety as a single agent in heavily pre-treated patients with advanced breast cancer harbouring the TP53 Y220C mutation. • Genomic testing is crucial to identify patients with TP53 Y220C mutations who may benefit from this novel treatment approach with rezatapopt.
