This was a Phase 2, multicenter, open-label, 2-cohort, 2-stage study that assessed the ORR of lenvatinib in previously treated participants with AJCC unresectable Stage III or Stage IV melanoma and disease progression. Cohort 1 enrolled participants not harboring the V600E BRAF mutation with disease progression following up to 2 prior systemic anticancer regimens (excluding anti-VEGF) for unresectable Stage III or Stage IV melanoma, and is referred to as Cohort 1 or V600E BRAF negative. Other less common BRAF activating mutations were allowed as long as the participant did not receive a BRAF-targeted therapy. Cohort 2 enrolled participants harboring the activating BRAF mutations (mainly the V600E mutation) with disease progression following BRAF V600E-targeted therapy, and is referred to as Cohort 2 or V600E BRAF positive. Eligible participants had measurable disease according to RECIST 1.1.
The purpose of this study is to assess the objective response rate of lenvatinib in previously treated participants with American Joint Committee on Cancer (AJCC) unresectable Stage III or Stage IV melanoma and disease progression.
