Prospective, Randomized, Multicenter, Open Label, Phase II Study to Access Efficacy and Safety of Lucentis® Monotherapy Compared With Lucentis® Plus Panretinal Photocoagulation (PRP) and PRP in the Treatment of Patients With High Risk Proliferativ

• Status: Completed
• Trial end date: 2013-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this trial is to evaluate safety and to compare the efficacy of intravitreous injection of ranibizumab alone (0.5 mg), versus combination of intravitreous injection of ranibizumab (0.5 mg) plus panretinal photocoagulation, versus panretinal photocoagulation alone in the regression of retinal neovascularization in eyes with high-risk proliferative diabetic retinopathy.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: José Cunha-Vaz
• Treatments: Ranibizumab

Criteria

Inclusion Criteria:

• High-risk proliferative diabetic retinopathy (HR-PDR) eyes.

• Best Corrected-Visual Acuity at baseline > 20/320 in the study eye.

• Clear ocular media and adequate pupillary dilatation to permit good quality fundus photography.

• Intraocular pressure < 21 mmHg.

• Type I, or Type II diabetic subjects as defined by the World Health Organization criteria of either gender, and aged ≥ 18 years.

• Women must be using effective contraception, be post-menopausal for at least 12 months prior to trial entry, or surgically sterile.

• Ability to provide written informed consent.

• Ability to return for all trial visits.

Exclusion Criteria:

• Eyes with prior scatter (panretinal) or focal/grid photocoagulation, within the previous 6 months.

• Fibrovascular proliferation with retinal traction.

• Other cause of retinal neovascularization (retinal vein occlusion, radiation retinopathy or others).

• Atrophy/scarring/fibrosis/ hard exudates involving the center of the macula.

• Subjects who have received yttrium-aluminum-garnet laser, or peripheral retinal cryoablation, or laser retinopexy (for retinal tears only), or focal/grid photocoagulation, within the previous 6 months.

• Significant media opacities, which might interfere with visual acuity, assessment of toxicity or fundus photography.

• Subjects should not be entered if there is likelihood that they will require cataract surgery within the following 1 year.

• Any intraocular surgery within 6 months before trial enrollment.

• Previous vitrectomy.

• HbA1C level >11% or recent signs of uncontrolled diabetes.

• Any of the following underlying systemic diseases:

• History or evidence of severe cardiac disease.

• History or evidence of clinically significant peripheral vascular disease such as intermittent claudication or prior amputation.

• Clinically significant impaired renal function (serum creatinine >2.5 mg/dL or s/p renal transplant or receiving dialysis).

• Clinically significant impaired hepatic function.

• Stroke (within 12 months of trial entry).

• Any major surgical procedure within one month before trial enrollment.

• Previous radiation to the head in the region of the study eye.

• Any prior treatment with an investigational agent for diabetic retinopathy or anti-VEGF therapy (including intravitreal, subconjunctival or subtenons corticosteroids) during the past 90 days for any other condition.

• Known serious allergies to fluorescein used in angiography, or to components of Lucentis® formulation.

• Systolic Blood Pressure > 170 (2 different readings) or diastolic Blood Pressure > 100 (2 different readings).

• Acute ocular or periocular infection.

• Previous filtering surgery (e.g., trabeculectomy) or placement of a glaucoma drainage device (e.g., tube-shunt surgery).

• Use of other investigational drugs at the time of enrollment.

• History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes.

• History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.

• Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (> 5 mIU/mL).

• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant UNLESS they are: women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner; women whose partners have been sterilized by vasectomy or other means using a highly effective method of birth control. Periodic abstinence are not acceptable.
