A Study to Investigate the Safety, Efficacy and PK of Multiple Doses of QL-007 in Chronic Hepatitis B Patients in CHINA

An Open-Label Phase 1b Study to Evaluate the Dose-Related Safety, Efficacy, and Pharmacokinetic Profile of Different Doses of QL-007 in Chronic Hepatitis B Patients

This is a randomized, open-label, positive-control, dose-escalation Phase 1b trial in 60 patients with chronic HBV infection to determine the safety, preliminary efficacy, and pharmacokinetics (PK) of QL-007 after administration over 28 days of multiple oral doses in a fasted state at the following planned dose levels: 200, 400, and then 600 mg.
