          -  Body mass not less than 50 kg.

          -  Medical history, vital signs, physical examination, standard 12-lead electrocardiogram
             (ECG) and laboratory investigations must be clinically acceptable or within laboratory
             reference ranges for the relevant laboratory tests, unless the investigator considers
             the deviation to be irrelevant for the purpose of the study.

          -  Non-smokers.

          -  Females, if:

          -  Not of childbearing potential, e.g., has been surgically sterilized, undergone a
             hysterectomy, amenorrhea for ≥ 12 months and considered post-menopausal, Note: In
             post-menopausal women, the value of the serum pregnancy test may be slightly
             increased. This test will be repeated to confirm the results. If there is no increase
             indicative of pregnancy, the female will be included in the study.

          -  Of childbearing potential, the following conditions are to be met:

          -  Negative pregnancy test If this test is positive, the subject will be excluded from
             the study. In the rare circumstance that a pregnancy is discovered after the subject
             received IMP, every attempt must be made to follow her to term.

          -  Abstaining from sexual activity (if this is the usual lifestyle of the subject) or
             must agree to use an accepted method of contraception, and agree to continue with the
             same method throughout the study An example of a reliable method of contraception is a
             non-hormonal intrauterine device. In this study the concomitant use of hormonal
             contraceptives is NOT allowed. Other methods, if considered by the investigator as
             reliable, will be accepted.

          -  Written consent given for participation in the study.

          -  Written consent given for participation in the genetic component of the study (if
             performed based on Food and Drug Administration (FDA) feedback). If the subject
             declines participation in the genetic component, the subject will not be allowed to
             participate in the study.

        Exclusion Criteria:

          -  Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional
             or intellectual problems likely to limit the validity of consent to participate in the
             study or limit the ability to comply with protocol requirements.
