A First-in-Human Single and Multiple Ascending Dose Study of MT-501

This study is the first administration of MT-501 in healthy volunteers (HV). The purpose of the study is to evaluate the safety, tolerability, and pharmacokinetics (PK) and pharmacodynamics (PD) of single and repeat oral doses of up to 8 days of MT-501 in HV. The safety, tolerability, PK, and PD data obtained from this study will inform further development of MT-501.
