The study is designed to evaluate the safety and efficacy of suprachoroidally administered triamcinolone acetonide, CLS-TA, in subjects with macular edema associated with non-infectious uveitis.

This is a Phase 3, randomized, masked, sham-controlled, multicenter study to assess the safety and efficacy of 4 mg of CLS-TA administered via suprachoroidal injection compared to a sham injection procedure in the treatment of subjects with macular edema associated with non-infectious uveitis.

Qualified subjects will be randomized to receive two suprachoroidal injections of CLS-TA administered to the study eye or two sham injection procedures administered to the study eye approximately 12 weeks apart (Visit 2 and Visit 5). Follow-up visits will be conducted monthly up to 24 weeks (Visit 8).

Inclusion Criteria:

• Diagnosis of non-infectious uveitis (pan, anterior, intermediate and posterior)
• Diagnosis of macular edema associated with non-infectious uveitis (retinal thickness ≥ 300 microns)
• Visual Acuity score of ≥ 5 letters read (20/800 Snellen equivalent) and ≤ 70 letters read (20/40 Snellen equivalent), in the study eye

Exclusion Criteria:

• Any active ocular disease or infection in the study eye other than uveitis
• Intraocular pressure > 22 mmHg or uncontrolled glaucoma in the study eye; subjects are not excluded if IOP ≤ 22 mmHg with no more than 2 IOP lowering medications.
• Any uncontrolled systemic disease that, in the opinion of the Investigator, would preclude participation in the study
• Any topical ocular corticosteroid in the 10 days prior to baseline; intraocular or periocular corticosteroid injections in the 2 months prior to baseline; an OZURDEX implant in the 6 months prior to baseline; RETISERT or ILUVIEN implant in the 3 years prior to baseline.
