Patients will not receive rAAV.sFlt-1, but will be eligible for retreatment with ranibizumab (Lucentis).
A new treatment for exudative age-related macular degeneration (wet AMD) is being investigated. The purpose of this Phase I/II clinical research study is to examine the baseline safety and efficacy of an experimental study drug to treat a complication of the disease which leads to vision loss. The name of the study drug is rAAV.sFlt-1.
This experimental study uses a non-pathogenic virus to express a therapeutic protein within the eye. The therapeutic diminishes the growth of abnormal blood vessels under the retina. The duration of effect is thought to be long-term (years) following a single administration.
The clinical research study will look at the baseline safety and efficacy of a single injection of rAAV.sFlt-1 injected directly into the eye.
Approximately forty (40) subjects will participate in Australia. The primary endpoint of the study is at one month, with extended follow up for 3 years.
