Brief summary
The purpose of this study is to find out the efficacy and safety of oral FXS5626 in participants with active, non-anterior (intermediate, posterior, or pan) non-infectious uveitis (NIU).
Detailed description
This study is a multicenter, randomized, double-blind, placebo-controlled study conducted in china, aimed at evaluating the efficacy, safety and tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of FXS5626 administered twice daily for 24 weeks in participants with active, non-anterior (intermediate, posterior, or pan) non-infectious uveitis(NIU). This study plans to enroll 40 patients with active non-anterior NIU. Patients who sign the informed consent form will be screened according to the enrollment criteria, and randomly allocated into 3 groups in a 2:1:1 ratio. Participants in groups 1 and 2 will receive different doses of FXS5626. Participants in group 3 will receive placebo.
