Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion criteria:

All the following inclusion criteria had to be met for a participant to be eligible to be included in this study:

1. Provide a signed and dated ICF.
2. Healthy participant. Note: defined as an absence of clinically significant abnormalities and any active medical conditions, as identified by a detailed medical history, complete physical examination, vital signs, clinical laboratory tests, cardiac and ophthalmologic evaluation as assessed by the Investigator.
3. Male and female between ≥ 18 and ≤ 65 years of age (at the day of signature of consent).
4. Female participants had to be postmenopausal or sterilized. Note: due to preclinical data of teratogenicity and lack of data on human pregnancies with binimetinib, women of childbearing potential were excluded from this study.

   Women were considered postmenopausal and not of childbearing potential if they had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum follicle stimulating hormone (FSH) levels \> 40 mIU/mL and estradiol \< 20 pg/mL (except if treated with hormone replacement therapy \[HRT\]) or had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks prior to dosing. In case of doubt on the menopausal status, the participant was not included. In the case of oophorectomy alone, the reproductive status of the woman was to be confirmed by a follow-up hormone level assessment to consider her of non-childbearing potential.
5. Men with a female partner of childbearing potential were required to use an effective method of birth control or practice abstinence for the entire study duration and for up to 30 days following the last dose of the study treatment.

   Note: the following birth control was recommended: condom for the male participant and an intrauterine device with spermicide or oral or implanted hormonal contraception for the female partner.
6. Body mass index (BMI) of ≥ 18.5 to \< 30 kg/m2 with body weight ≥ 50 kg and \< 100 kg.
7. Vital signs within the following ranges or if out of normal ranges, considered as not clinically significant by the Investigator except for high diastolic blood pressure (BP): (After at least 5 minutes rest in the supine position)

   1. Supine systolic BP ≥ 90 mmHg and ≤ 140 mmHg
   2. Supine diastolic BP ≥ 50 mmHg and ≤ 90 mmHg
   3. Supine pulse rate (PR) ≥ 45 to ≤ 100 beats per minute (bpm)
   4. Body temperature between ≥ 35.0°C and ≤ 37.5°C
   5. Orthostatic hypotension had to be ruled out based on the following criteria after standing for 5 minutes:

   i. More than a 20 mmHg decrease in systolic BP or 10 mmHg decrease in diastolic BP ii. Clinical signs/symptoms of postural hypotension (dizziness, syncope, etc.), regardless of vital signs.
8. Participants had to have safety laboratory values within the normal ranges or if out of normal ranges considered as not clinically significant by the Investigator except for the following parameters:

   1. Total bilirubin ≤ upper limit of normal (ULN).
   2. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyltransferase (GGT) ≤ ULN and alkaline phosphatase (ALP) ≤ 1.1 X ULN.
   3. Serum creatinine within normal range, except on P1D-1 and P2D-1 (≤ 1.1 X ULN).
   4. Serum amylase and lipase ≤ ULN.
   5. Fasting glucose, coagulation panel (prothrombin ratio) within normal range and activated partial thromboplastin time (aPTT) ≤ 1.1 X ULN.

   NB: It was to be noted that for the parameters acceptable at ≤ 1.1 X ULN, if more than one parameter exceeded ULN, the participant was excluded.
9. Able to communicate well with the Investigator and comply with the requirements of the study.
10. Participants had to be willing to comply with dietary and fluid restrictions (from D-7 to 72 hours after the last study treatment administration, see Section 9.4.7.3).
