(Phase 3) Comparison of Duration of Response (DOR) in Doublet Arm vs Control Arm Per Investigator

Study of Encorafenib + Cetuximab Plus or Minus Binimetinib vs. Irinotecan/Cetuximab or Infusional 5-Fluorouracil (5-FU)/Folinic Acid (FA)/Irinotecan (FOLFIRI)/Cetuximab With a Safety Lead-in of Encorafenib + Binimetinib + Cetuximab in Patients With BRAF V600E-mutant Metastatic Colorectal Cancer · Source last updated 2023-12-21

What was measured

DOR was defined as the time from first radiographic evidence of response to the earliest documented PD or death due to underlying disease. PD: at least a 20% increase (including an absolute increase of at least 5 mm) in the sum of diameters of target lesions, taking as reference the smallest sum on study and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions were evaluated.

Analysis population: The Phase 3 Response Efficacy Set consisted of the first 330 participants randomized into the Phase 3 portion of the study and any additional participants randomized on the same day as the 330th randomized participant. Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure.

Groups in this outcome

Phase 3: Doublet Arm

Encorafenib + cetuximab. Encorafenib: Orally, once daily. Cetuximab: Standard of care.

Phase 3:Control Arm

Investigator's choice of either irinotecan/cetuximab or FOLFIRI/cetuximab. Cetuximab: Standard of care. Irinotecan: Standard of care. Folinic Acid: Standard of care. 5-Fluorouracil: Standard of care. Following protocol amendment, eligible participants could crossover to receive either triplet or doublet regimen.
