Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Male subjects must not donate sperm during this period. 7. The subject must be willing to adhere to the study protocol, including visits, study treatment, laboratory tests, and other study-related procedures and requirements. Exclusion Criteria: 1. Known allergy to the study drug or its excipients, or a history of severe allergic reactions (including any food allergies or drug allergies). 2.
