Phase I Dose Escalation Safety Study of RetinoStat in Advanced Age-Related Macular Degeneration (AMD) (GEM)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01301443
Recruitment Status : Completed
First Posted : February 23, 2011

Brief Summary:
The purpose of this first in man study is to examine the safety of an experimental gene transfer agent, RetinoStat, designed to treat neovascular age-related macular degeneration.

Condition or disease Intervention/treatment Phase
Age Related Macular Degeneration Drug: Subretinally injected RetinoStat Phase 1

Detailed Description:
There are two parts to the study. A dose-escalation phase looking at three doses of RetinoStat starting with the lowest dose, three patients will be recruited at each dose level. The escalation phase will be followed by a dose confirmation phase where the highest dose that is safe and well tolerated will be examined in 9 patients.
