Clinical trials

This Phase 3, double-blind (sponsor-open), multicenter, placebo-controlled study aims to evaluate the efficacy and safety of oral LW402 tablets in patients with moderate to severe atopic dermatitis.

This is a Phase Ib/II, multicenter, randomized, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of LW231 in participants with chronic hepatitis B virus (HBV) infection. The trial will include multiple-dose regimens of LW231 and assess LW231 in combination with NUCs.

This is a multicenter, randomized, double-blind, placebo-controlled Phase II clinical trial designed to assess the efficacy, safety, and tolerability of LW402 tablets in participants with non-segmental vitiligo. Drawing on the prior/preclinical data of LW402 tablets, this clinical trial will incorporate three dose groups: 50 mg twice daily (BID), 100 mg BID, and 150 mg BID. The trial will be structured into a screening period (maximum 5 weeks), a treatment period (52 weeks, encompassing a 24-week main trial phase and a 28-week extension phase), and a safety follow-up period (4 weeks). The maximum duration of participation in this study will be 61 weeks. Following the completion of 24-week data collection for all trial participants, unblinding will be performed in accordance with the pre-specified procedure. Subsequently, based on the unblinded data results, regulatory communication will be conducted with the Center for Drug Evaluation (CDE) regarding the initiation of the Phase III confirmatory clinical trial. Participants who have undergone unblinding will continue to attend scheduled study visits to complete the trial.
