Summary

This study is a Phase I/II, multicenter, randomized, study of the efficacy and safety of ranibizumab injection monotherapy verses a duel therapy of 0.3mg ranibizumab combined with ultra wide, 200° field angiography guided pan retinal photocoagulation in patients with CSME-CI secondary to diabetes mellitus (Type 1 or 2).

Detailed description

Approximately 40 eyes will be randomized at 3 investigational centers in the United States. This study consists of a screening period of up to 14 days (Days -14 to -1), and a 36-month treatment period (Day 0 to Month 36). Subjects who provide consent will enter the screening period to determine eligibility. As part of the screening process, the examining investigator will evaluate the macular foveal avascular zone fluorescein images to determine subjects' eligibility. Eligible subjects will be randomized in a 1:1 ratio so that approximately 20 eyes will receive 0.3 mg ranibizumab monotherapy, and approximately 20 eyes will receive 0.3 mg ranibizumab combined with Ultra wide 200° field angiogram guided targeted pan retinal photocoagulation (PRP). Subjects must meet VA and retinal thickness eligibility requirements during the screening period. The subject can have both eyes in the study. If both eyes are eligible, one eye will be randomized, to cohort 1 while the other eye will be randomized to the cohort 2. A subject with both eyes in the trial will have each eye in a separate cohort.

Conditions

• Diabetic Macular Edema

Interventions

Type	Name	Description
DRUG	0.3 mg ranibizumab	Cohort 1: Subjects will receive 4 mandatory intravitreal injections of 0.3 mg ranibizumab every 28 days (+/- 7 days). They will then be seen monthly (+/- 7 days) and will receive intravitreal injections of 0.3 mg ranibizumab on a PRN schedule per retreatment criteria based on the evaluating Investigator's assessment of disease activity.
PROCEDURE	Targeted Pan Retinal Photocoagulation	Cohort 2: Subjects will receive 4 mandatory intravitreal injections of 0.3 mg ranibizumab every 28 days (+/- 7 days). They will then be seen monthly (+/- 7 days) and will receive intravitreal injections of 0.3 mg ranibizumab on a PRN schedule per retreatment criteria based on the evaluating Investigator's assessment of disease activity. In addition, at V3 (Day 7) they will receive targeted pan retinal photocoagulation (PRP) based on ultra wide 200º field angiography. After the first session of PRP, subject's will have ultra wide 200º field angiography performed every 3 months to indicate areas of peripheral ischemia, which will be selectively treated at V9 (Month 6), V21 (Month 18), and V28 (Month 25), preserving areas of more perfused retina. This will minimize any visual field loss secondary to nonselective pan-retinal photocoagulation.
