Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–70 with active intermediate, posterior, or pan non-infectious uveitis who meet weight and BMI requirements and can comply with study procedures are the intended participants.
✕Probably not a fit
Patients with infectious uveitis, anterior-only uveitis, or those who cannot meet the screening stability criteria or required corticosteroid background therapy are unlikely to benefit from this protocol.

What this trial studies
This is a multicenter, randomized, double-blind, placebo-controlled Phase 2 study in China enrolling about 40 adults with active intermediate, posterior, or panuveitis. Participants are randomized 2:1:1 to one of two FXS5626 dose levels or placebo and receive treatment twice daily for 24 weeks. The protocol includes safety monitoring, measurement of uveitis activity, and collection of pharmacokinetic and pharmacodynamic data. Efficacy endpoints focus on change in ocular inflammation while tolerability and adverse events are tracked throughout the study.
Why it matters
Potential benefit: If successful, FXS5626 could reduce eye inflammation and lower the need for high-dose corticosteroids in people with active non-anterior NIU.
How similar studies have gone: Oral and systemic immunomodulatory therapies have shown benefit in NIU in prior studies, but FXS5626 is a new molecule being specifically tested for efficacy, safety, PK, and PD in this population.
