A Study of Vemurafenib Adjuvant Therapy in Participants With Surgically Resected Cutaneous BRAF-Mutant Melanoma

• Status: Completed
• Trial end date: 2018-07-13
• Target enrollment: 0
• Participant gender: All

Summary

This multicenter, randomized, double-blind, placebo-controlled study will evaluate the efficacy and safety of vemurafenib in participants with completely resected, cutaneous BRAF mutation-positive melanoma at high risk for recurrence. Participants will be enrolled in two separate cohorts: Cohort 1 will include participants with completely resected Stage IIC, IIIA (participants with one or more nodal metastasis greater than [>] 1 millimeter [mm] in diameter), or IIIB cutaneous melanoma, as defined by the American Joint Committee on Cancer (AJCC) Classification, Version 7; Cohort 2 will include participants with Stage IIIC cutaneous melanoma, as defined by this classification scheme. Within each cohort, participants will be randomized (1:1 ratio) to receive vemurafenib or matching placebo over a 52-week period.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Hoffmann-La Roche
• Treatments: Vemurafenib
