A Single Ascending and Repeated Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of TS-142 in Healthy Participants

Phase 1
Completed
Conditions
Healthy Volunteers
Interventions
Drug: TS-142 Placebo
Registration Number
NCT04464239
Lead Sponsor
Taisho Pharmaceutical R&D Inc.
Brief Summary

This is a study to evaluate the safety, tolerability, and pharmacokinetics of single oral doses of TS-142 compared to placebo and of a single repeated dose compared to placebo in healthy volunteers. This Phase I study is composed of two parts; Part A (Single Ascending Dose) and Part B (Repeated Dose). The study employs a randomized, double-blind, placebo-controlled, parallel group design to evaluate the single and repeat-dose safety and pharmacokinetics of TS-142 in healthy participants.
