A Phase II, Randomised, Open Label Study of Neoadjuvant Dabrafenib, Trametinib and / or Pembrolizumab in BRAF V600 Mutant Resectable Stage IIIB/C Melanoma

This study aims to determine which of 3 drug combinations best reduces the size of tumour prior to surgery for advanced melanoma and prevents the recurrence of melanoma after surgery.

NCT02858921 Melanoma
MeSH: Melanoma
HPO: Cutaneous melanoma Melanoma

3 Interventions

Name: Dabrafenib

Description: Dabrafenib, a 4-(3-aminosulfonylphenyl)-5-(pyrimidine-3-yl) thiazole, is a potent and selective inhibitor of B-RAF kinase activity with a mode of action consistent with adenosine triphosphate (ATP)-competitive inhibition, and is approved as monotherapy in BRAF V600E-mutant advanced/metastatic melanoma.

Type: Drug

Concurrent D + T AND Pembrolizumab Sequential D + T, THEN Pembrolizumab

Name: Trametinib

Description: Trametinib, a pyrido - pyrimidine derivative, is a potent and highly selective allosteric non-competitive inhibitor of MEK1/MEK2 activation and kinase activity has been approved as monotherapy in BRAF (V600E)-mutant and BRAF (V600K)-mutant melanoma.

Type: Drug

Concurrent D + T AND Pembrolizumab Sequential D + T, THEN Pembrolizumab

Name: Pembrolizumab

Description: Pembrolizumab is a potent and highly selective humanized monoclonal antibody (mAb) of the IgG4/kappa isotype designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2.

Type: Drug

Concurrent D + T AND Pembrolizumab Pembrolizumab ONLY Sequential D + T, THEN Pembrolizumab


Primary Outcomes

Measure: Incidence of post operative infection

Time: 6 weeks
