Recruitment status

COMPLETED

Target enrollment

33 participants

Primary outcome timeframe

6 months following completion of the Parent study CLS1001-301 (NCT02595398), for a total of up to 1 year

Participant Flow

Subjects enrolled into the Parent study CLS1001-301 (NCT02595398), and who completed the Parent study without receiving additional therapy for uveitis were eligible for enrollment into this non-interventional observation extension study. The Parent study was still masked when subjects started enrolling into this extension study, therefore, treatment assignment was unknown at study entry and during the study.

Subjects enrolled into this non-interventional observational extension study successfully completed the Parent study CLS1001-301 (NCT02595398) without requiring additional therapy for uveitis. In the Parent study, subjects were randomized 3:2 to either 4 mg CLS-TA or a sham procedure in a masked fashion. Eligible and consenting subjects from selected sites were enrolled into the non-interventional extension study.

Population: The Safety population included all enrolled subjects who successfully completed the enrollment visit of the extension study. Results include those subjects with gradable images at follow-up week 24. Values for missing data were not imputed.

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.

Population: The Safety population included all enrolled subjects who successfully completed the enrollment visit of the extension study. Results include those subjects with non-missing BCVA values at follow-up week 24. Values for missing data were not imputed.

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.
