Phase 2 Study of FORE8394 Plixorafenib to Treat Cancers with BRAF Alterations Including Solid and Central Nervous System Tumors

What this Trial Is About

This research aims to evaluate the effectiveness and safety of plixorafenib in participants with cancers that have specific BRAF gene alterations. These include locally advanced or metastatic solid tumors, primary central nervous system tumors, and rare BRAF V600E-mutated solid tumors such as anaplastic thyroid, ovarian, and cholangiocarcinoma cancers. The study focuses on participants with BRAF V600E mutations or BRAF fusions and seeks to understand treatment effects across various cancer types. Participants receive plixorafenib orally in continuous 3-week cycles. Dosing may be increased as tolerated and continues until disease progression, unacceptable side effects, or withdrawal for other reasons. The study includes different subprotocols tailored to tumor type and BRAF alteration, such as unresectable solid tumors with BRAF fusions, recurrent primary CNS tumors with BRAF V600E mutations, rare non-CNS solid tumors with BRAF V600E mutations, and other advanced solid tumors with BRAF V600E mutations. Participants will undergo scans before starting treatment to assess tumor changes, and regular monitoring will continue during treatment. Researchers will evaluate tumor response, progression-free survival, overall survival, treatment safety, and drug levels in the blood over up to approximately four years. The study tracks side effects and collects detailed pharmacokinetic data to understand how the drug is processed. Participants remain in the study until disease progression or other withdrawal criteria are met, with ongoing safety and efficacy assessments.
