Study Arms (2)

0.3 mg Ranibizumab

ACTIVE COMPARATOR

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.

Drug: 0.3 mg ranibizumab

Targeted PRP with 0.3 mg Ranibizumab

EXPERIMENTAL

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.

Drug: 0.3 mg ranibizumabProcedure: Targeted Pan Retinal Photocoagulation

Interventions

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.

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willingness to provide signed informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization.
  • Age ≥ 18 years
  • Diabetes Mellitus (Type 1 or 2). The following will be considered as sufficient evidence that diabetes is present:
  • Current regular use of insulin for the treatment of diabetes
  • Current regular use of oral antihyperglycemic agents for the treatment of diabetes
  • Documented diabetes according to the American Diabetes Association and/or World Health Organization criteria.
  • BCVA score in the study eye of 20/32 to 20/320 approximate snellen equivalent using the ETDRS protocol at an initial testing distance of 4 meters, confirmed by the investigator.
  • High Definition OCT (Spectralis) central retinal thickness measurement of ≥ 300 µm
  • Decrease in visual acuity is determined to be primarily the result of DME and not to other cause.
  • Ability and willingness to return for all scheduled visits and assessments.
  • Clear ocular media and adequate pupillary dilatation to permit good quality fundus photography.

You may not qualify if:

  • Subjects who meet any of the following criteria will be excluded from this study:
  • Pregnancy (positive pregnancy test) or lactation
  • Sexually active women of childbearing potential\* who are unwilling to practice adequate contraception or abstinence during the study. (\*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)
  • Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated
  • Prior Ocular Treatment:
  • History of vitrectomy surgery in the study eye
  • Any pan-retinal photocoagulation in the study eye
  • Prior treatment with intraocular or subconjunctival steroids in the study eye 4 months prior to screen
  • Previous treatment with antiangiogenic drugs in either eye (pegaptanib sodium, anecortave acetate, bevacizumab, ranibizumab, etc.) within 2 months of Day 0 visit
  • Systemic corticosteroids 4 months prior to screen
  • 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
  • Active intraocular inflammation (grade trace or above) in the study eye
  • Current vitreous hemorrhage in the study eye
  • History of rhegmatogenous retinal detachment or macular hole (Stage 3 or 4) in the study eye
  • +20 more criteria
