A Study to Detect V-Raf Murine Sarcoma Viral Oncogene Homolog B1 (BRAF) V600 Mutation on Cell-Free Deoxyribonucleic Acid (cfDNA) From Plasma in Participants With Advanced Melanoma
- Registration Number
- NCT02768207
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This is a single arm, multicenter, open label, and non-randomized clinical study on adult participants with unresectable or metastatic melanoma. The study will be conducted in two phases. Pre-screening phase will assess the BRAF V600 mutation in a new mutation analysis triggered by a mutant plasma cfDNA test result. Treatment phase will assess the clinical outcome for the participants treated with vemurafenib plus cobimetinib. The length of the study will be approximately 38 months.

Inclusion Criteria
Pre-screening phase:
- Participants with histologically confirmed cutaneous melanoma, either unresectable Stage IIIc or Stage IV metastatic melanoma, as defined by American Joint Committee on Cancer 7th edition
- Documentation of BRAF V600 test result mutation-positive status on melanoma tumor tissue using a validated tissue test
Treatment Phase:
- Eastern Cooperative Oncology Group performance status of 0-2
- Adequate hematologic and end organ function obtained within 14 days prior to first dose of study drug treatment
- Negative serum pregnancy test prior to commencement of dosing in women of childbearing potential

- Female participants of childbearing potential and male participants with partners of childbearing potential must agree to always use two effective forms of contraception during the course of this study and for at least 6 months after completion of study therapy
- Participants should be able to swallow tablets
- Documentation of BRAF mutation positive status in melanoma tissue
Exclusion Criteria
Treatment Phase:

Group Intervention Description Treatment Phase: Vemurafenib+Cobimetinib Cobimetinib Participants with BRAF V600 mutation will receive vemurafenib 960 milligrams (mg) tablets orally twice daily (BID) on Days 1 to 28 along with cobimetinib 60 mg tablets orally once daily (OD) for 21 consecutive days (Days 1 to 21) of each 28-day cycle until disease progression, consent withdrawal, or the development of unacceptable toxicity. Treatment Phase: Vemurafenib+Cobimetinib Vemurafenib Participants with BRAF V600 mutation will receive vemurafenib 960 milligrams (mg) tablets orally twice daily (BID) on Days 1 to 28 along with cobimetinib 60 mg tablets orally once daily (OD) for 21 consecutive days (Days 1 to 21) of each 28-day cycle until disease progression, consent withdrawal, or the development of unacceptable toxicity.
