The reference (R) formulation is the currently commercially available tablet containing 15 mg of binimetinib as active substance, administered as three tablets for a total of 45 mg binimetinib. The Test (T) formulation is the tablet containing 45 mg of binimetinib as active substance in one tablet. Participants will be randomized to one of 2 treatment sequences (RT or TR) containing 2 treatment periods, with at least a 7-day washout between each dose.~The study will consist of a screening period between 21 and 2 days before the first study treatment administration on Period (P) 1 Day (D) 1, 2 treatment periods of 5 days each, and a washout of at least 7 days between P1D1 and P2D1.~Study treatments are given by the oral route in fasted condition. The end-of-study (EOS) visit will be performed 30 (± 3) days after the last study treatment administration or discontinuation.
The current commercially available MEKTOVI® (binimetinib) 15 mg tablets are provided as immediate release film-coated tablets for oral administration. For the treatment of adult patients with unresectable or metastatic melanoma with BRAF V600 mutation, the recommended dosing regimen is 45 mg twice daily (bis in die, BID). No food effect with the commercial formulation of 15 mg was demonstrated. In order to reduce the patient's burden, a new strength tablet containing 45 mg of binimetinib as active ingredient is being developed. As a result, the number of tablets to be taken by the patients will be reduced from 6 tablets (6 x 15 mg) to 2 tablets (2 x 45 mg) per day. The evaluation of the bioequivalence between one 45 mg tablet and three 15 mg tablets is therefore required.
