Pegaptanib Sodium Compared to Sham Injection in Patients With Recent Vision Loss Due to Macular Edema Secondary to Central Retinal Vein Occlusion (CRVO)

This study has been completed.
Information provided by:
Eyetech Pharmaceuticals Identifier:
First received: July 23, 2004
Last updated: January 17, 2007
Last verified: January 2007

Eyetech Pharmaceuticals Inc. and Pfizer, Inc. are studying an investigational drug, MacugenTM, for the possible treatment of CRVO. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This investigational drug may slow the growth of abnormal blood vessels in the eye and may reduce tissue swelling in the eye.

The purpose of this study is to compare the safety and efficacy of a Macugen™ injection to a “pretend” injection. In addition, the purpose of this study is to measure the action of the study drug in the body over a period of time and to check for the presence of the study drug in your blood (called pharmacokinetics or PK).

This study will involve approximately 90 people. People who decide to participate will have an equal chance (1 in 3) to receive one of three study injections, two of which are Macugen™ and one of which is a “pretend” injection.

Condition Intervention Phase
Retinal Vein Occlusion Drug: pegaptanib sodium Phase 2

Primary Purpose: Treatment
Official Title: A Phase II Randomized, Dose-Ranging, Double-Masked, Multi-Center Trial, in Parallel Groups, Determining Safety, Efficacy and PK of Intravitreous Injections of Pegaptanib Sodium Compared to Sham Injection for 30 Weeks in Patients With Recent Vision Loss Due to Macular Edema Secondary to CRVO

Estimated Enrollment: 90
Study Start Date: May 2004
Detailed Description:
This study will consist of 3 phases: a screening phase which will last up to two weeks, a confirmation phase which will last one day, and a randomization phase (the patient will be assigned by chance to a study group in this phase) which will last approximately 52 weeks.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • CRVO must have occurred within the past 6 months and be associated with macular edema determined by OCT.
  • Vision in the study eye corresponding to between approximately 20/50 to 20/400 and better than or equal to approximately 20/200 in the fellow eye.

Exclusion Criteria:

  • Presence of signs of old branch retinal vein occlusion (BRVO) or CRVO in the study eye or any other retinal vascular disease including diabetic retinopathy.
  • Vitreous hemorrhage except breakthrough hemorrhage from intraretinal hemorrhage.
  • Prior pan retinal photocoagulation (PRP) or sector scatter photocoagulation.
