* With any clinically significant abnormality following review of pre-study laboratory tests (aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT) and alkaline phosphatase (ALP) must be within normal ranges), vital signs, full physical examination and Electrocardiogram (ECG),
* Who are within the exclusion period defined in the National Register for Healthy Volunteers of the French Ministry of Health,
* Who forfeit their freedom by administrative or legal award or who were under guardianship,
