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

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 2
