This study is a non-interventional, observational extension of the Parent study, CLS1001-301 (NCT02595398). The purpose of this study is to characterize the continued clinical benefit(s) regarding safety and efficacy of suprachoroidally administered CLS-TA, triamcinolone acetonide injectable suspension, for the treatment of macular edema associated with non-infectious uveitis.
This is a non-interventional, observation extension study of up to 6 months for subjects completing the Parent study, CLS1001-301 (NCT02595398). The Parent study is a Phase 3, multicenter study to assess the safety and efficacy of 4 mg of CLS-TA administered via suprachoroidal injection compared to a sham procedure in the treatment of subjects with macular edema associated with non-infectious uveitis. The design of the Extension study includes 4 clinic visits over a maximum of 24 weeks. Subject eligibility will be established at Visit 1 during the crossover day from the Parent study to the extension study (Day 0). Follow-up visits will be conducted every 6 weeks up to 24 weeks (Visit 4). At Visit 4, subjects will have a final evaluation conducted 24 weeks following study entry (48 weeks from Parent study randomization). This study was initiated prior to the completion of the parent study, therefore treatment assignment was masked prior to study entry.

Time to Additional Therapy for Uveitis
This time to event outcome was calculated as the number of days between the date of initiation of additional therapy for uveitis and the date of first treatment in the Parent study CLS1001-301 (NCT02595398).
Time frame: 6 months following completion of the Parent study CLS1001-301 (NCT02595398), for a total of up to 1 year
Number of Participants With Treatment Emergent Adverse Events and Serious Adverse Events
Number of participants with treatment emergent adverse events and serious adverse events reported during the extension study.
Time frame: 6 months following exit from Parent study
Mean Change From Baseline in Central Subfield Thickness
Central subfield thickness (CST) is a diagnostic measurement used in identifying the presence of edema in the circular area 1 mm in diameter centered around the fovea. CST was measured using spectral domain optical coherence tomography (SD-OCT). A masked reading center graded the SD-OCT digital images. A negative change from baseline value represents a reduction in macular edema.
Time frame: 6 months following exit from Parent study
Mean Change From Baseline in Best Corrected Visual Acuity
Best corrected visual acuity (BCVA) refers to the measurement of the best possible vision that can be achieved following refraction or correction. BCVA was assessed following the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol and was measured in the number of letters read correctly on an ETDRS eye chart. An increase from the pre-treatment state in BCVA of 15 letters or more represents a clinically meaningful improvement.
