Conditions

Non-Infectious Uveitis of the Posterior Segment of the Eye

Brief summary

The objective of this extension study is to evaluate the long-term safety of treatment with DE-109 (440 μg) in subjects with non-infectious uveitis of the posterior segment of the eye who have participated in the SAKURA development program.

Detailed description

This is a multicenter, open-label, extension study of intravitreal injections of the 440 μg dose of DE-109 in subjects with non-infectious uveitis of the posterior segment who received any dose of DE-109 and exited the SAKURA program under Santen Protocol 32-007, Amendment 05. Subjects who were randomized and received at least two injections of DE-109 during the first five months of the SAKURA program and obtained clinical benefit from the study medication, as determined by the Investigator, may be considered for entry in this 12-month extension study. The minimum time lag from last injection in the SAKURA program to entry into the current protocol is 60 days.

Change From Baseline in Best Corrected Visual Acuity (BCVA) at Month 12 in the Study EyeDay 1 (Baseline) and Month 12 or early termination visitBest Corrected Visual Acuity (BCVA) measures the acuteness or clearness of best-corrected vision in ETDRS (Early Treatment of Diabetic Retinopathy Study) letters. An increase in BCVA indicates improvement in the best-corrected vision. A BCVA score of 85 ETDRS letters is equivalent to 20/20 vision, which is considered normal vision.

Outcome results

Change From Baseline in Best Corrected Visual Acuity (BCVA) at Month 12 in the Study Eye

Best Corrected Visual Acuity (BCVA) measures the acuteness or clearness of best-corrected vision in ETDRS (Early Treatment of Diabetic Retinopathy Study) letters. An increase in BCVA indicates improvement in the best-corrected vision. A BCVA score of 85 ETDRS letters is equivalent to 20/20 vision, which is considered normal vision.
