About FORE8394

FORE8394 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, FORE8394 does not induce paradoxical activation of the RAF/MEK/ERK pathway. As a “paradox breaker,” FORE8394 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 FORE8394 in advanced solid and CNS tumors with activating BRAF alterations, providing evidence of durable anti-tumor activity in patients with BRAF-mutated (V600+) cancers. The data were presented at the European Society of Medical Oncology Congress (ESMO) in September 2022.
