Trial to Evaluate the Efficacy and Safety of TP-03, LIBRA Study
- Registration Number
- NCT05629390
- Lead Sponsor
- LianBio LLC
- Brief Summary
The Phase III main study is a randomized, controlled, multicenter, double blind, trial to evaluate the efficacy and safety of TP-03 (lotilaner ophthalmic solution, 0.25%), for the treatment of Demodex blepharitis in Chinese patients. The PK sub-study is a single-arm, open-label trial to evaluate systemic TP-03 in whole blood following topical ocular administration
- Detailed Description
The main study is designed to demonstrate the superiority of TP-03 compared to vehicle for the treatment of Demodex blepharitis in Chinese patients. The vehicle of TP-03 was selected as the control since there are no approved pharmaceutical treatments for Demodex blepharitis. The vehicle as the control will provide evidence that the active ingredient is responsible for the response, not the vehicle alone.
A pharmacokinetics (PK) sub-study is included in the overall study design to evaluate systemic PK parameters of TP-03 in Chinese participants with Demodex blepharitis. The PK sub-study sites are separate from those of the Phase III study as described above.
