Patients with metastatic or unresectable locally advanced malignancies harboring BRAF genomic
alterations, the biological target of vemurafenib, and who are no more amenable to curative
To explore the efficacy of vemurafenib as a single agent across diverse type of tumors guided
by the presence of identified activating molecular alterations in the vemurafenib target
gene, per cohort.
This is a biology driven, trans-tumoral, multicentric phase II trial assessing the efficacy
and the safety of the targeted agent vemurafenib as a monotherapy in cohorts of patients with
identified activating molecular alterations in BRAF gene. A cohort is defined by a pathology
and a BRAF- alteration (eg ovarian cancer with BRAF V600 mutation).
To explore the efficacy of vemurafenib per pathology and per target. To assess the safety
profile of vemurafenib. To explore whether molecularly driven, high quality multi-tumor
screening phase II trials are feasible in the French multiinstitutional, multidisciplinary
To investigate the additional molecular mechanisms in patients with tumor response versus
patients without tumor response within the same cohort.
