About

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) profile of different doses of TG-2349 (Furaprevir capsule) in healthy Chinese volunteers.

Full description

This study is to evaluate the safety, tolerability, and pharmacokinetics (PK) profile in healthy Chinese volunteers with single or multiple ascending oral doses of TG-2349 (Furaprevir capsule). The study is separated into two parts, part A and part B.

Part A：To evaluate the safety, tolerability, and PK profile of single ascending oral dose (100 mg, 200 mg, 400 mg, and 600 mg) of TG-2349 in healthy Chinese volunteers.

Part B：To evaluate the safety, tolerability, and PK profile of multiple ascending oral doses (200 mg, 400 mg, and 600 mg) of TG-2349 for five days in healthy Chinese volunteers.

Enrollment: 64 patients

Sex: All

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers
