An Open-Label, Extension (Rollover) Study of Vemurafenib in Patients With BRAF V600 Mutation-Positive Malignancies Previously Enrolled in an Antecedent Vemurafenib Protocol
This open-label, multicenter, non-randomized study will provide continued access to vemurafenib for eligible participants with BRAF V600 mutation-positive malignancy, who were previously enrolled and treated in an antecedent vemurafenib protocol and did not meet the protocol's criteria for disease progression, or are treated beyond progression and are still deriving clinical benefit (as assessed by investigator), and may therefore potentially benefit from continued treatment with vemurafenib. Participants will receive treatment with oral vemurafenib at 960 milligrams (mg) twice daily (BID), 720 mg BID, or 480 mg BID, depending on the last dose in the antecedent protocol. Treatment will continue until progression of disease or as long as the participant is deriving clinical benefit, as judged by the investigator (case-by-case decision with approval of the Medical Monitor), death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the study, whichever occurs first.

Accepting Healthy Volunteers?
- BRAF V600 mutation-positive malignancy
- Prior eligibility for and on study treatment from an antecedent vemurafenib protocol
- Ability to begin treatment in the extension (rollover) protocol within 15 days following the last day of the study in the antecedent protocol
- Female participants of childbearing potential and male participants with partners of childbearing potential must agree to use 2 adequate methods of contraception as defined by protocol during the course of this study and for at least 6 months after completion of study treatment
- Adverse event requiring discontinuation of vemurafenib in the antecedent protocol
- Progressive disease during the antecedent protocol. If approval to treat beyond progression was already given in the antecedent protocol, the participant may roll over into the current protocol without sponsor approval. Under special circumstances, enrollment into this protocol and dosing beyond progression may be considered and will require approval of the sponsor
Participants meeting any of the following exclusion criterion of the antecedent study at the time the participant is considered for the extension (rollover) study:
- Current, recent (within 28 days prior to Day 1), or planned use of any antitumor therapy outside this study
- Any other serious concomitant medical condition that, in the opinion of the investigator, would compromise the safety of the participant or compromise the participant's ability to participate in the study
- History of malabsorption or other clinically significant metabolic dysfunction
- History of clinically significant cardiac or pulmonary dysfunction as specified in antecedent study
- Malignant Melanoma
