ROAR
A Phase II, Open-label, Study in Subjects With BRAF V600E-Mutated Rare Cancers With Several Histologies to Investigate the Clinical Efficacy and Safety of the Combination Therapy of Dabrafenib and Trametinib: biliary tract cancer cohort
Phase 2N = 43NCT02034110
- Population
- Adults with BRAF V600E-mutated unresectable, metastatic, locally advanced or recurrent biliary tract cancer, ECOG performance status 0-2, who had received previous systemic treatment; 43 evaluable patients.
- Design
- Part of an ongoing phase 2, open-label, single-arm, multicentre basket trial (Rare Oncology Agnostic Research, ROAR); this record covers the biliary tract cancer cohort given dabrafenib 150 mg twice daily plus trametinib 2 mg once daily until progression or intolerance. Primary endpoint: overall response rate by RECIST 1.1 in the intention-to-treat evaluable population. Results are from an interim analysis; median follow-up 10 months (IQR 6-15). The registry record covers all ROAR cohorts (206 patients). Single-arm; no comparison group.
- Primary endpoint
- ORR
- Arms
- Dabrafenib plus trametinib (experimental, n = 43): Dabrafenib 150 mg orally twice daily plus trametinib 2 mg orally once daily
