Brief Summary

The purpose of the Columbus-AD study is to evaluate the efficacy and safety of 12 months of encorafenib in combination with binimetinib in adjuvant setting of BRAF V600E/K mutant stage IIB/C melanoma versus the current standard of care (surveillance).

Detailed Description:
This is a randomized triple-blind placebo-controlled international multicenter phase III superiority clinical trial.

Participants with completely resected cutaneous melanoma and documented BRAF V600E/K status by central assay will be randomized 1 to 1 to receive either treatment with encorafenib and binimetinib or their two placebos for 12 months. Patients will be stratified according to the stage of the disease according to AJCC version 8 between:

  • stage IIB (i.e., pT3b or pT4a)
  • stage IIC (i.e., pT4b).

The long-term evaluation of all endpoints (including information about the occurrence of new treatment-related adverse events, if any) will take place 10 years from the randomization of the last patient.
