Participant gender:
All
Summary
Primary Objective: To investigate the effectiveness of intravitreal applications of 0.5 mg Lucentis (ranibizumab) in patients with vitreous hemorrhage due to proliferative diabetic retinopathy. The primary endpoint for the study will be the mean change in best-corrected visual acuity (BCVA) from baseline to the mean level at Month 3. Secondary Objectives: 1. To assess any differences in mean change in BCVA over time; 2. To assess differences in vitreous transparency (amount of hemorrhage) with fundus angiography exam; 3. To assess any differences in retinopathy severity level according to the Early Treatment Diabetic Retinopathy Study; 4. To correlate the visual outcomes with serum glucose levels.

Criteria
Inclusion Criteria:

- Male or female patients >18 years of age who have signed an informed consent

- Patients with Type 1 or Type 2 diabetes mellitus (according to ADA or WHO guidelines).

- Patients with visual impairment due to vitreous hemorrhage.

- Medication for the management of diabetes must have been stable within 3 months prior
to randomization and is expected to remain stable during the course of the study.

Exclusion criteria:

Ocular concomitant conditions/ diseases

- Concomitant conditions in the study eye which could, in the opinion of the
investigator, prevent the improvement of visual acuity on study treatment

- Active intraocular inflammation (grade trace or above) in either eye

- Any active infection (e.g. conjunctivitis, keratitis, scleritis, uveitis,
endophthalmitis) in either eye

- History of uveitis in either eye

- Ocular disorders in the study eye that may confound interpretation of study results,
compromise visual acuity or require medical or surgical intervention during the
12-month study period, including retinal vascular occlusion, retinal detachment,
macular hole, or choroidal neovascularization of any cause (e.g., age-related macular
degeneration, ocular histoplasmosis, or pathologic myopia)

- Uncontrolled glaucoma in the study eye (according to investigator's judgment)

- Neovascularization of the iris in study eye

- Evidence of vitreomacular traction in study eye

Ocular treatments

- Panretinal laser photocoagulation in the study eye within 6 months or focal/grid laser
photocoagulation in the study eye within 3 months prior to study entry

- Treatment with anti-angiogenic drugs (pegaptanib sodium, anecortave acetate,
bevacizumab, ranibizumab, etc.) or intravitreal corticosteroids in either eye within 4
months prior to randomization

- Any intraocular surgery in the study eye within 3 months prior to randomization

- History of vitrectomy in study eye

- Phakic study eye with a history of intravitreal corticosteroid treatment

- Ocular conditions in the study eye that require chronic concomitant therapy with
topical ocular or systemically administered corticosteroids

Systemic conditions or treatments

- History of 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, might affect the interpretation of
the results of the study, or renders the patient at high risk from treatment
complications

- Renal failure requiring dialysis or renal transplant OR renal insufficiency with
creatinine levels >2.0 mg/dl

- Untreated diabetes mellitus

- Severe (blood pressure systolic > 160 mmHg OR diastolic > 100 mmHg) AND untreated
hypertension

- Current use of or likely need for systemic medications known to be toxic to the lens,
retina or optic nerve, including Deferoxamine, Chloroquine/ hydroxychloroquine
(Plaquenil), Tamoxifen, Phenothiazines and Ethambutol

- Known hypersensitivity to ranibizumab or any component of the ranibizumab formulation
or to fluorescein contrast.

Compliance/ Administrative

- Previous participation in any clinical studies of investigational drugs (excluding
vitamins and minerals) within 1 month (or a period corresponding to 5 half-lives of
the investigational drug, whatever is longer) prior to randomization

- Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, including women whose career, lifestyle, or sexual orientation
precludes intercourse with a male partner and women whose partners have been
sterilized by vasectomy or other means, UNLESS they are using two birth control
methods. The two methods can be a double barrier method or a barrier method plus a
hormonal method. Adequate barrier methods of contraception include: diaphragm, condom
(by the partner), intrauterine device (copper or hormonal), sponge or spermicide.
Hormonal contraceptives include any marketed contraceptive agent that includes an
estrogen and/or a progestational agent.

- Pregnant or nursing (lactating) women.

- Inability to comply with study or follow-up procedures.
