Criteria

Inclusion Criteria:

Subjects will be required to satisfy the following criteria:

1. Healthy male subject, aged between 18 and 45 years inclusive.

2. Considered as healthy after a comprehensive clinical assessment (detailed medical history and complete physical examination).

3. Body mass index (BMI) between 18 and 30 kg/m² inclusive.

4. Normal blood pressure (BP) and heart rate (HR) at the screening visit after 5 min in supine position:

• 90 mmHg ≤ Systolic Blood Pressure (SBP) ≤ 145 mmHg,

• 45 mmHg ≤ Diastolic Blood Pressure (DBP) ≤ 90 mmHg,

• 40 bpm ≤ HR ≤ 90 bpm,

• Or considered not clinically significant (NCS) by the Investigator.

5. Normal electrocardiogram (ECG) recording on a 10 min resting 12-lead ECG at the screening visit:

• 120 ≤ interval between P and R waves (PR) < 210 ms,

• Interval between Q and S waves (QRS) < 120 ms,

• Fridericia corrected interval between Q and T waves (QTcF) ≤ 450 ms,

• No sign of any trouble of sinusal automatism,

• Or considered NCS by the Investigator.

6. Laboratory parameters within the normal range of the laboratory (hematological, blood chemistry tests, urinalysis). Individual values out of the normal range can be accepted if judged clinically non relevant by the Investigator.

7. Normal dietary habits.

8. Has given written informed consent.

Exclusion Criteria:

All the subjects included in the study must not meet any of the following non-inclusion criteria.

3. Evidence of any clinically significant acute or chronic disease,

4. Surgery or blood donation (including in the frame of a clinical trial) within 2 months before administration,

5. Presence or relevant history of drug hypersensitivity, asthma or allergic disease diagnosed and treated by a physician,

6. Known hypersensitivity to any of the test materials or related compounds,

7. Inability to abstain from intensive muscular effort,

8. Inability or difficulty swallowing whole capsules

9. No possibility of contact in case of emergency,

10. Any drug intake (except paracetamol) including over the counter (OTC) medications and herbal products that could affect the outcome of the study, within 2 weeks prior to the first drug administration or less than 5 times the t1/2 of that drug, whichever is longer,

11. Who receive carbamazepine, phenytoin or phenobarbital known to affect hepatic metabolism within 1 month prior to the first dose administration,

12. Who receive any drug known to interfere with CYP enzymes within 1 month prior to the first dose administration,

13. History or presence of drug or alcohol abuse (alcohol consumption > 4 glasses per day (1 glass is approximately equivalent to: beer [354 mL], wine [118 mL], or distilled spirits [29.5 mL]) per day)),

14. Excessive consumption of beverages with xanthine bases (> 5 cups or glasses / day),

15. Current use of nicotine containing products, i.e., more than 5 cigarettes or equivalent/day or the inability to stop using nicotine containing products during confinement in the clinical center,

16. Intake of any food or any beverage containing grapefruit or grapefruit juice within one week prior to the first dosing and the inability to stop such intake during the study,

17. Positive Hepatitis B surface antigen (HBsAg) or anti Hepatitis C Virus (HCV) antibody, or positive results for Human Immunodeficiency Virus (HIV) 1 or 2 tests,

18. Positive results of screening for drugs of abuse,

19. Subject who, in the judgment of the Investigator, is likely to be non-compliant or uncooperative during the study, or unable to cooperate because of a language problem, poor mental development,

20. Exclusion period of a previous study,

21. Administrative or legal supervision.
