A Phase 2 Master Protocol to assess the efficacy and safety of FORE8394, an inhibitor of BRAF Class 1 and Class 2 alterations, in participants with cancer harboring BRAF alterations
EU CTIS ID: 2024-513578-23-00
What this study is testing
The objective of this study is to evaluate the efficacy of plixorafenib in participants with locally advanced or metastatic solid tumors, or recurrent or progressive primary central nervous system (CNS) tumors harboring BRAF fusions, or in participants with rare and/or selected solid tumors, or recurrent primary CNS tumors harboring BRAF V600E mutation. This will be conducted as four open-label subprotocols (F8394-201A; F8394-201B; F8394-201C; F8394-201D) under one Master Protocol.

Note: Participants with pediatric-type LGGs (molecular classification byWHO2021; diagnosed at ≤25 years of age) who had received prior treatment(s)with RAF/BRAF inhibitors are eligible for enrollment, provided there was no evidence of tumor progression on that therapy or within 4 weeks of discontinuation, based upon radiographic assessment.
- Subprotocol D: 2. Participant has CNS metastases.
- Subprotocol B: 2. Known or suspected neurofibromatosis-1 (NF-1) and/or Ras related gene alterations.
- Subprotocol A: 4. Tyrosine kinase inhibitor(s) and/or targeted therapies are allowed (other than BRAF/MAPK pathway inhibitors per Exclusion Criteria 3 and 4) and will be restricted to no more than the number of lines of therapy that are consistent with standard treatment guidelines. NOTE: There is no restriction on the number of lines of chemotherapy or immunotherapy.
