Macugen for Proliferative Diabetic Retinopathy Study With Extended Dosing (M-PDRS ED)

Proliferative Diabetic Retinopathy Clinical Trial

Official title:
A Pilot Study to Determine if Intravitreal Injections of Pegaptanib Sodium (Macugen) Given Every 12 Weeks for a Year After an Induction Phase of Three Injections Every 6 Weeks Will Reduce the Progression of Proliferative Diabetic Retinopathy in Patients Without Significant Vitreous Hemorrhage in Comparison to Treatment With Retinal Photocoagulation Alone and After an Induction Phase

Clinical Trial Summary

Intravitreal injections of pegaptanib will induce the regression of Proliferative Diabetic Retinopathy (PDR) and reduce the need for retinal photocoagulation.

Clinical Trial Description

Primary Objective:

To further establish the efficacy of intravitreal pegaptanib injections in the regression of retinal neovascularization secondary to high-risk PDR, as compared to standard panretinal photocoagulation (PRP)

Secondary Objective:

To maintain the regression of PDR after the induction phase with intravitreal pegaptanib injections administered at 12-week intervals, as compared to standard PRP

To maintain the regression of PDR after the induction phase with retinal photocoagulation applied to areas of ischemia (Selective Laser Photocoagulation), as compared to standard PRP

To evaluate the rate of recurrence of neovascularization after 6 intravitreal pegaptanib injections

To determine if intravitreal pegaptanib will reduce the area and/or volume of concomitant diabetic macular edema, as assessed by leakage on fluorescein angiography (FA) and/or optical coherence tomography (OCT)

To determine if intravitreal pegaptanib injections maintain or reduce the loss of best-corrected visual acuity ;
