Positive Outcome From FORTE Basket Study of Plixorafenib Monotherapy in Recurrent or Progressive BRAF V600 Primary CNS Tumors Announced

“We are very pleased that the BRAF V600 primary CNS basket of the FORTE study has passed the protocol-specified interim analysis supporting that tumor regressions in patients treated with plixorafenib continue to be observed,” said Stacie Peacock Shepherd, M.D., Ph.D., Chief Medical Officer of Fore. “We believe this is an encouraging development for the study, and more importantly, for patients in need of novel treatment options for recurrent primary CNS tumors. The data with this novel BRAF inhibitor, known as a paradox breaker, builds on the recent momentum for the potential of plixorafenib to benefit patients across BRAF-altered solid tumors, including the recent presentation of encouraging data in patients with BRAF-altered thyroid cancers, which has generated significant enthusiasm in the field. This significant milestone builds upon the validated approach of targeting BRAF, while avoiding the limitations of the earlier generation compounds that led to rapid recurrence of disease and the need for combination with a MEK inhibitor, and brings us one step closer to our objective of accelerating access to adults and children diagnosed with recurrent BRAF-altered brain or spinal cord tumors. We look forward to completing enrollment and reporting topline results from this registrational CNS basket in the second half of 2026.”
