For first-line targeted therapy in patients with BRAF V600 positive metastatic melanoma 

First-line TAFINLAR + MEKINIST demonstrated durable responses, with a median duration of response of 39.6 months in patients who achieved a CR in the COMBI-v trial1

TAFINLAR® (dabrafenib) + MEKINIST® (trametinib) duration of response
  • The majority of patients (53%) who achieved a CR on first-line TAFINLAR + MEKINIST remained in CR after a median follow-up of 23 months in the COMBI-v study1

In the 2 phase 3 studies, TAFINLAR + MEKINIST demonstrated durable responses, with median durations of response ranging from 12.9 to 13.8 months1,2

Duration of response phase 3 studies TAFINLAR® (dabrafenib) + MEKINIST® (trametinib)
  • In COMBI-v, the median duration of response with TAFINLAR + MEKINIST was 13.8 months compared with 7.9 months with vemurafenib1
  • In COMBI-d, the median duration of response with TAFINLAR + MEKINIST was 12.9 months compared with 10.6 months with TAFINLAR monotherapy2
CR, complete response.

COMBI-AD was a double-blind, placebo-controlled, Phase 3 trial that compared Tafinlar + Mekinist vs placebo4


  • Resection of histologically confirmed Stage IIIA, B, or C with BRAF V600E or BRAF V600K mutation
  • ECOG performance status ≤1
  • No prior systemic anticancer treatment or radiotherapy for melanoma
2 mg QD (n=438)

Placebo (n=432)


  • Primary endpoint was RFS
  • Secondary endpoints were OS, distant metastasis-free survival, freedom from relapse, and safety
