Study Arms (2)
Ranibizumab 0.5mg
EXPERIMENTALIntravitreal injections of ranibizumab 0.5mg dose for six monthly treatments then additional treatments with ranibizumab 0.5mg dose if the subject meets re-treatment criteria.
Ranibizumab 2.0 mg
EXPERIMENTALIntravitreal injections of ranibizumab 2.0 mg dose for six monthly treatments then additional treatments with ranibizumab 2.0 mg dose if the subject meets re-treatment criteria.
Interventions
Intravitreal injections of ranibizumab 0.5mg dose for six monthly treatments then additional treatments with ranibizumab 0.5mg dose if the subject meets re-treatment criteria.
Eligibility Criteria
You may qualify if:
- Signed informed consent and authorization of use and disclosure of protected health information
- Age ≥18 years
- Diagnosis of diabetes mellitus (type 1 or type 2)
- Serum HbA1c ≥ 5.5% within 12 months of randomization. Retinal thickening secondary to diabetes mellitus (diabetic macular edema) involving the center of the fovea
- Diagnosis must be confirmed by fluorescein angiography and OCT images
- Foveal thickness of ≥ 250 μm,
- Best corrected visual acuity score in the study eye of 20/40 to 20/320 inclusive (Snellen equivalents using the ETDRS protocol at a distance of 4 meters). The non-study eye must be ≥ 20 letters (approximate Snellen equivalent 20/400).
- In the opinion of the investigator, decreased vision in the study eye is due to foveal thickening from DME and not from other obvious causes of decreased vision If a female of childbearing potential, a negative pregnancy test and commitment to the use of at least two forms of effective contraception (birth control) for the duration of the study are necessary.
You may not qualify if:
- Panretinal photocoagulation or macular photocoagulation within 3 months of study entry in the study eye
- Use of intraocular or periocular injection of steroids in the study eye (e.g., triamcinolone) within 3 months of study entry
- Previous participation in a study and receipt of anti-angiogenic drugs (pegaptanib sodium, ranibizumab, bevacizumab, anecortave acetate, protein kinase C inhibitor, etc.) within 2 months of study entry
- Proliferative diabetic retinopathy in the study eye, with the exceptions of
- Inactive, fibrotic proliferative diabetic retinopathy that has regressed following panretinal laser photocoagulation OR
- Tufts of neovascularization elsewhere (NVE) less than one disc area with no vitreous hemorrhage
- Vitreomacular traction or epiretinal membrane in the study eye evident biomicroscopically or by optical coherence tomography (OCT)
- Structural damage to the center of the macula in the study eye likely to preclude improvement in visual acuity following the resolution of macular edema, including atrophy of the retinal pigment epithelium, subretinal fibrosis, laser scar(s), macular ischemia, or organized hard exudate plaque
- Ocular disorders in the study eye that may confound interpretation of study results, including retinal vascular occlusion, retinal detachment, macular hole, or choroidal neovascularization of any cause (e.g., age related macular degeneration (AMD), ocular histoplasmosis, or pathologic myopia)
- Concurrent disease in the study eye that could compromise visual acuity or require medical or surgical intervention during the first 6-month study period
- Cataract surgery in the study eye within 3 months of study entry; Yttrium-Aluminum- Garnet (YAG) laser capsulotomy within 1 month of study entry; or any other intraocular surgery within 3 months preceding Day 0.
- History of vitreoretinal surgery in the study eye within 3 months of study entry
- Uncontrolled glaucoma (defined as intraocular pressure ≥30 mm Hg despite treatment with anti-glaucoma medications)
- Blood pressure exceeding 180/100 (sitting) during the screening period
- Uncontrolled diabetes mellitus, as evidenced by glycosylated hemoglobin (HbA1c) value \>13%
- +10 more criteria
