A Phase I/II, Randomized, Study for Diabetic Macular Edema Using 0.3mg Ranibizumab Combined With Targeted PRP Monthly for 4 Months,Then PRN vs. 0.3mg Ranibizumab 4 Months Monotherapy, Then as Needed(DME-AntiVEgf) DAVE
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.

Exclusion Criteria:
Subjects who meet any of the following criteria will be excluded from this study:
General Exclusion Criteria
- Pregnancy (positive pregnancy test) or lactation

(*Although no birth control method is 100% effective, the following are considered adequate means of contraception: surgical sterilization, use of oral contraceptives, barrier contraception using either a condom or diaphragm with spermicidal gel, intrauterine devices, or contraceptive hormone implants or patches. A subject's primary care physician, obstetrician, or gynecologist should be consulted regarding an appropriate form of birth control)

Concurrent Ocular Conditions:
- Any concurrent ocular condition in the study eye (e.g., cataract or age-related macular degeneration) that, in the opinion of the investigator could: require medical or surgical intervention during the study period to prevent or treat visual loss that might result from that condition; or, if allowed to progress untreated, could likely contribute to a loss of at least 2 Snellen equivalent lines of BCVA over the study period

- Atrial fibrillation not managed by subject's primary care physician or cardiologist within 3 months of screening visit
- History of stroke within the last 3 months of screening visit
- History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that might affect the interpretation of the results of the study or renders the patient at high risk for treatment complications

Active Comparator: 0.3 mg Ranibizumab
Cohort 1: Subjects will receive 4 IVT of 0.3 mg ranibizumab every 28 days (+/- 7 days), then will be seen monthly (+/- 7 days) & will receive IVT of 0.3 mg ranibizumab on a pro re nata (PRN) schedule per retreatment criteria.
|
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.

Experimental: Targeted PRP with 0.3 mg Ranibizumab
Cohort 2: Subjects will receive 4 it of 0.3 mg ranibizumab every 28 days (+/- 7 days), then will then be seen monthly (+/- 7 days) & receive IVT 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 Day 7 they will receive targeted pan-retinal photocoagulation (PRP) based on ultra wide field angiography.
Ultra wide field angiography will be performed every 3 months to indicate areas of peripheral ischemia, which will be selectively be treated with PRP at Month 6, Month 18, and Month 25, preserving areas of more perfused retina.

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.
