First-in-Human Study With Single and Multiple Doses of TS-161 in Healthy Participants

Phase 1
Completed
Conditions
Healthy Volunteers
Interventions
Drug: TS-161 Placebo
Registration Number
NCT03919409
Lead Sponsor
Taisho Pharmaceutical R&D Inc.
Brief Summary

This is a Phase 1, first-in-human study involving single and multiple oral doses of TS-161 in healthy male and female participants. The safety, tolerability, pharmacokinetics and pharmacodynamics of TS-161 will be evaluated.

The study includes 3 parts; Part A (single ascending dose: Cohorts 1 to 5) , Part B (single dose, cerebrospinal fluid \[CSF\] collection: Cohort 6), and Part C (multiple ascending dose: Cohorts 7 to 9). Participants will be assigned to one of the 9 Cohorts.
