Description of intervention(s) / exposure
This is a 3 year multicenter, randomized, double-masked controlled study to evaluate the safety and efficacy of an Intravitreal Fluocinolone Acetonide (0.59 and 2.1 mg) implant in patients with unilateral or bilateral non-infectious uveitis affecting the posterior segment of the eye. Eligible subjects will receive either a 0.59mg or 2.1mg implant (assigned according to a randomization code) surgically inserted in one eye. In patients with bilateral disease, the more severely affected eye will be implanted.
Subjects will be followed for a period of 3 years, the approximate time period over which the implants are designed to release FA.

Outcomes
Primary outcome [1] 821 0
The primary efficacy outcome in this trial is the proportion of patients who suffer a recurrence of uveitis in the study eye within 34 weeks following implantation vs proportion of patients who suffered a recurrence in the 34 weeks preceding implantation.
Assessment based on presence or absence of statistically significant difference (two-tailed, alpha =0.05)
Timepoint [1] 821 0
Secondary outcome [1] 1632 0
Secondary efficacy outcomes consist of recurrence rates and time-to-failure in study vs fellow eyes, changes to the adjunctive treatment required to control uveitis, proportion of patients with improvement of visual acuity, cystoid macula edema, treatment dose effects on recurrence rates and time-to-failure, and improvement in QOL survey scores.
Timepoint [1] 1632 0
The analysis of efficacy and safety will take place when all subjects have completed a 34-week period post implantation and reviewed at 1, 2 and 3 years post implantation.
Secondary outcome [2] 1633 0
Safety variables include: Proportion of eyes with IOP control issues i.e. IOP>25mmHg and <6mmHg, Increase in lens opacity by 2 grades from baseline, reduction of >10dB in visual field defect mean deficit, adverse events, concomitant medication, changes in vital signs, clinical laboratory values, visual acuity and ophthalmoscopic examination findings.
Timepoint [2] 1633 0
The analysis of efficacy and safety will take place when all subjects have completed a 34-week period post implantation and reviewed at 1, 2 and 3 years post implantation.

Eligibility
Key inclusion criteria
One or both eyes having a history of non-infectious uveitis affecting the posterior segment of the eye > 1 yr requiring either systemic or sub-tenon injections of corticosteroid, study eye must be clinically quite at the time of implantation and have visual acuity of at least 1.4logMar units.
Minimum age
6 Years
Maximum age
Not stated
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Allergy to FA, history of only posterior segment uveitis without vitritis or macula edema, history of iritis only and no vitreous cells or haze, uveitis of infectious etiology, vitreous hemorrhage, presence of toxoplasmosis scar in study eye, peripheral retinal detachment in area of implantation, media opacity precluding ophthalmic evaluation, presence or history or uncontrolled IOP, ocular surgery within 3 months of enrollment, subjects requiring chronic systemic corticosteroid or immunosuppressive therapy for non-ocular conditions, subjects tested positive for HIV, pregnant or lactating females, females of childbearing potential considering becoming pregnant during the course of the study and not taking effective contraception, subjects whose special risks outweigh the potential benefits of participating in the study, subjects who are unlikely to comply with study protocol and visit schedule, subjects who are currently enrolled in any other IND or have participated in an IND within 1 month of enrollment.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The investigational material pouches have a two part, double masked label, such that the dose of FA implant is not revealed to investigator or subject. Eligible subjects are assigned a randomization number based on enrollment order which correspond to the randomization number on the label of the implant pouch.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomization table prepared and assignment to treatment group stratified based on method of disease management most recently practiced at the time of enrollment
Masking / blinding
Blinded (masking used)
