Number of Responders at Day 15 Primary · Baseline (Day 1), Day 15

Response was defined as a two-step decrease or more from baseline in Anterior Chamber (AC) Cell Grade as per Standardization of Uveitis Nomenclature (SUN). Baseline was defined as the measurement taken before drug administration on Day 1. Subjects receiving rescue treatment on or before Day 15 were considered non-responders. Only one eye contributed to the analysis.

Mean Best Corrected Visual Acuity (BCVA) at Each Visit Primary · Baseline (Day 1), Day 4, Day 8, Day 15, Day 22, Day 29

Visual Acuity (VA) with the subject's best spectacles or other visual corrective devices was measured using an Early Treatment of Diabetic Retinopathy Study (ETDRS) or Snellen visual acuity chart and reported in letters read correctly. An increase (gain) in letters read indicates improvement. Only one eye contributed to the analysis.

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry or Tonopen and reported in millimeters mercury (mmHg). A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Only one eye contributed to the analysis.

Number of Subjects With Increase From Baseline in Slit Lamp Parameters at Any Post-Treatment Visit Primary · Baseline (Day 1), Day 4, Day 8, Day 15, Day 22, Day 29

Slit-lamp biomicroscopy (examination) was performed to evaluate the anterior segment of the eye, including lids/lashes, conjunctiva, cornea, anterior chamber (cells and flare), iris, and lens. Ocular signs were categorized as Aqueous Flare, Aqueous Inflammatory Cell Grade, Keratic Precipitates, Lens, Limbal Injection, Status of Lens, Peripheral Anterior Synechia, and Posterior Synechia. An increase indicates worsening. Only one eye contributed to the analysis.

Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. Only one eye contributed to the analysis.
