A Phase IIIb, Multinational, Multicenter, Open-Label Extension Study Assessing the Long-Term Safety of PRN Intravitreal Injections of DE-109 in Subjects With Non-Infectious Uveitis of the Posterior Segment of the Eye Who Have Participated in the SAKURA Development Program (SPRING)

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.

Study Overview

• Status: Completed
• Conditions: Non-Infectious Uveitis of the Posterior Segment of the Eye
• Intervention / Treatment: Drug: DE-109 440 μg

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	Day 1 (Baseline) and Month 12 or early termination visit
Mean Change From Baseline in Intraocular Pressure at Month 12 in the Study Eye	Intraocular pressure (IOP), the fluid pressure inside the eye, was measured by applanation tonometry in millimeters mercury (mmHg) with one decimal point.	Day 1 (Baseline) and Month 12 or early termination visit
Number of Subjects With a Shift in Choroid Status at Month 12 in the Study Eye.	Ophthalmoscopy findings were reported as normal or abnormal.	Day 1 (Baseline) and Month 12 or early termination visit
Changes From Baseline in Vitreous Haze (VH) Scores at Month 12	Vitreous Haze (VH) scores were measured using the modified Standardized Uveitis Nomenclature Photographic Scale (SUN) : 0 No inflammation 0.5+ Trace Inflammation (slight blurring of the optic disc margins and or loss of nerve fiber layer reflex); Mild blurring of the retinal vessels and optic nerve1.5+ Optic nerve head and posterior retina view obstruction greater than 1+ but less than 2+; Moderate blurring of the optic nerve head; Marked blurring of the optic nerve head; Optic Nerve head not visible	Day 1 (Baseline) and Month 12 or early termination visit
Number of Subjects Who Receive Rescue Therapy.	Rescue therapy was defined as any treatment that would have a therapeutic effect on the uveitis in the posterior segment (e.g., systemic treatment with an immunosuppressant agent, or a corticosteroid injection in the study eye) other than intravitreal DE-109 determined by the Investigator.	By Month12
Number of Subjects With a Shift in Macula Status at Month 12 in the Study Eye.	Ophthalmoscopy findings were reported as normal or abnormal.	Day 1 (Baseline) and Month 12 or early termination visit
Number of Subjects With a Shift in Optic Nerve Status at Month 12 in the Study Eye.	Ophthalmoscopy findings were reported as normal or abnormal.	Day 1 (Baseline) and Month 12 or early termination visit
Number of Subjects With a Shift in Retina Status at Month 12 in the Study Eye.	Ophthalmoscopy findings were reported as normal or abnormal.	Day 1 (Baseline) and Month 12 or early termination visit
