A Study of Vemurafenib in Participants With BRAF V600 Mutation-Positive Cancers
- Registration Number
- NCT01524978
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This open-label, multi-center study will assess the efficacy and safety of vemurafenib in participants with BRAF V600 mutation-positive cancers (solid tumors and multiple myeloma, except melanoma and papillary thyroid cancer) and for whom vemurafenib is deemed the best treatment option in the opinion of the investigator. Participants will receive twice daily oral doses of 960 mg vemurafenib until disease progression, unacceptable toxicity, or withdrawal of consent. The safety and efficacy of vemurafenib in combination with cetuximab in a subset of participants with colorectal cancer will also be assessed.

Safety: Percentage of Participants With Adverse Event Up to approximately 3 years An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
