Safety, Tolerability and Pharmacokinetics of 14-day Multiple Dose Titrations of TS-134 in Healthy Volunteers

A Randomized, Double-blind, Placebo-controlled, Multiple Ascending Dose Titration Study to Evaluate the Safety, Tolerability and Pharmacokinetics of TS-134 Administered Orally to Healthy Male and Female Subjects

This is a Phase 1 study involving multiple dose titrations of TS-134 in healthy male and female subjects. The safety, tolerability and pharmacokinetics of multiple dose titrations of TS-134 will be evaluated.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: TS-134; Healthy adult subjects will be prospectively assigned to 1 of 6 cohorts. Within each cohort, 10 subjects per cohort will be randomized in a 4:1 ratio (8 active + 2 placebo) to receive daily doses of TS-134 or placebo for 14 days in a fed state, with ascending titrated dose levels ranging from 5 mg to 80 mg, depending on the assigned cohort. The maximum daily dose shall not exceed 80 mg.	Drug: TS-134; 5 mg to 80 mg oral solution
Placebo Comparator: Placebo; Healthy adult subjects will be prospectively assigned to 1 of 6 cohorts. Within each cohort, 10 subjects per cohort will be randomized in a 4:1 ratio (8 active + 2 placebo) to receive daily doses of TS-134 or placebo for 14 days in a fed state, with ascending titrated dose levels ranging from 5 mg to 80 mg, depending on the assigned cohort. The maximum daily dose shall not exceed 80 mg.	Drug: Placebo; Matched Placebo oral solution
