PHILADELPHIA–(BUSINESS WIRE)–FORE Biotherapeutics today announced the acceptance of an abstract on new nonclinical data related to plixorafenib (FORE8394), the company’s novel, investigational, small-molecule, next-generation, orally available selective inhibitor of BRAF alterations at the 2023 AACR-NCI-EORTC International Conference, taking place October 11-14, 2023, in Boston and virtually. The data set presented in the poster shows improved drug activity for both V600 and non-V600 BRAF alternations from other pan-RAF and BRAF inhibitors.

About plixorafenib (FORE8394)
Plixorafenib is an investigational, novel, small-molecule, next-generation, orally available selective inhibitor of mutated BRAF. It was designed to target a wide range of BRAF mutations while sparing wild-type forms of RAF. Preclinical studies and clinical trials have shown that its unique mechanism of action effectively inhibits not only the constitutively active BRAFV600 monomers targeted by first-generation RAF inhibitors but also disrupts constitutively active dimeric BRAF class 2 mutants, fusions, splice variants and others. Unlike first-generation RAF inhibitors, plixorafenib does not induce paradoxical activation of the RAF/MEK/ERK pathway. As a “paradox breaker,” plixorafenib could therefore treat acquired resistance to current RAF inhibitors and, more generally, yield improved safety and more durable efficacy than first-generation RAF inhibitors. The company previously announced interim data from the ongoing Phase 1/2a clinical trial evaluating plixorafenib in patients with advanced solid tumors (including brain and spinal cord tumors) with activating BRAF alterations, providing evidence of durable anti-tumor activity in patients with BRAF-mutated cancers. The data were presented at the European Society of Medical Oncology Congress (ESMO) in September 2022 and ASCO 2023.
