F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 15

Exclusion Criteria

Eligible subjects must meet none of the following exclusion criteria at screening:

8.Loss or donation of blood over 500 mL within three months prior to screening or donation of plasma within 14 days of screening;
9.Any (medical) condition that would, in the opinion of the investigator, potentially compromise the safety or compliance of the patient or may preclude the patient’s successful completion of the clinical trial;
10.Chronic infection with HIV, hepatitis B (HBV) or hepatitis C (HCV). A positive HBV surface antigen (HBsAg) test at screening excludes a subject;
