Brief Summary

A study to evaluate the safety and efficacy of a fluocinolone acetonide intravitreal (FAI) insert in the management of subjects with chronic non-infectious uveitis affecting the posterior segment of the eye.

Detailed Description

This was a phase 3, multicenter, randomized, masked, controlled study to evaluate the safety and efficacy of an injectable FAI insert for the management of subjects with chronic non-infectious uveitis affecting the posterior segment of the eye. Subjects were randomized to receive either a sham injection or the FAI insert and were observed for 1 year following treatment.

25. Positive test for human immunodeficiency virus (HIV) or syphilis during Screening.

26. Mycobacterial uveitis or chorioretinal changes of either eye which, in the opinion of the Investigator, result from infectious mycobacterial uveitis.

27. Systemic infection within 30 days prior to Day 1.

28. Any severe acute or chronic medical or psychiatric condition that could increase the risk associated with study participation or could interfere with the interpretation of study results and, in the judgment of the Investigator, could make the subject inappropriate for study enrollment.

29. Any other systemic or ocular condition which, in the judgment of the Investigator, could make the subject inappropriate for study enrollment.

30. Treatment with an investigational drug or device within 30 days prior to Day 1.

Arm && Interventions

Group	Intervention	Description
Sham Comparator	Sham Injector	Intravitreal sham injection

Primary Outcome Measures

Name	Time	Method
Percentage of Subjects With Recurrence of Uveitis in the Study Eye at Week 24	Week 24	Recurrence was defined as: * An increase in the vitreous haze of ≥2 steps compared to baseline or any visit time point prior to the Week 24 visit; or; * A deterioration in visual acuity of at least 15 letters BCVA compared to baseline or any visit time point prior to the Week 24 visit.

Secondary Outcome Measures

Name	Time	Method
Percentage of Subjects With Recurrence of Uveitis in the Study Eye at Week 52	Week 52	Recurrence was defined as: * An increase in the vitreous haze of ≥2 steps compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit); or; * A deterioration in visual acuity of at least 15 letters BCVA compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit).
Percentage of Subjects With Recurrence of Uveitis in the Fellow Eye at Weeks 24 and 52	Weeks 24 and 52	Recurrence was defined as: * An increase in the vitreous haze of ≥2 steps compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit); or; * A deterioration in visual acuity of at least 15 letters BCVA compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit).
Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) Letter Score in the Study Eye at Weeks 24 and 52	Weeks 24 and 52	The BCVA was measured according to the standard procedure originally developed for Early Treatment Diabetic Retinopathy Study (ETDRS). The ETDRS letter score calculated when 20 or more letters were read correctly at 4.0 meters; the visual acuity letter score was equal to the total number of letters read correctly at 4.0 meters plus 30. The score ranges from 0 (worse) to 100 (best). Higher scores indicate positive outcome measure.
Number of Recurrences of Uveitis Within 24 and 52 Weeks	Weeks 24 and 52	Recurrence was defined as: An increase in the vitreous haze of ≥2 steps compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit); or A deterioration in visual acuity of at least 15 letters BCVA compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit).

Number of Adjunctive Treatments Required to Treat Recurrences of Uveitis at 24 and 52 Weeks	Weeks 24 and 52	Recurrence was defined as: An increase in the vitreous haze of ≥2 steps compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit); or A deterioration in visual acuity of at least 15 letters BCVA compared to baseline or any visit time point prior to the Week 24 visit (or the Week 52 visit).; In the event of a uveitis recurrence in either eye, peri-ocular or intraocular corticosteroid injections, or topical medications administered as first line local therapy.
Percentage of Subjects With Recurrence of Iridocyclitis in the Study Eye Compared to Baseline at 24 and 52 Weeks	Weeks 24 and 52	Iridocyclitis was defined as a \>2-step increase in anterior chamber cells per high-power field (HPF) (1.6\*using a 1-millimeter beam).
Percentage of Subjects With Resolution of Macular Edema at Day 28 and Months 2, 3, 6 and 12	At Day 28 and Months 2, 3, 6 and 12	The macular edema was measured by spectral-domain - optical coherence tomography (SD-OCT) imaging.
