7. Male participants and/or their female partners of child-bearing potential must use a highly effective form of contraception during the study and for 3 months after study completion
8. Provide their written informed consent prior to participation in the study

18. Inability to consume the study medication, or, in the opinion of the Investigator, inability to comply with the protocol
19. In the opinion of the Investigator, any medical condition, uncontrolled systemic disease, serious intercurrent illness, or extenuating circumstance occurring or persisting, within 30 days prior to baseline, that would significantly decrease study compliance or jeopardize the safety of the participant or affect the validity of the trial results
