A Phase 1 Safety Study of Single and Repeated Doses of JSM6427 (Intravitreal Injection) to Treat AMD

Phase 1

Completed

• Conditions: Macular Degeneration

• Registration Number: NCT00536016
• Lead Sponsor: Jerini Ophthalmic

Brief Summary

The purpose of this study is to determine the way and rate that the study medication, JSM6427 a potent, highly specific integrin α5β1-antagonist is absorbed, broken-down and eliminated from the body when it is given as a single dosage strength by injection into the eye. Repeated dosages will also be given to determine the highest safe dose.

Detailed Description

In non-clinical models, JSM6427 can lead to the inhibition and regression of choroidal neovascularization, making α5β1 an attractive target for therapeutic strategies directed at pathological angiogenesis. JSM6427 may also interfere with other key processes in the pathogenesis of AMD, namely inflammation and fibrosis. Further, non-clinical data show that JSM6427 inhibits scarring and inflammation. Thus, JSM6427 may target multiple important pathways in the pathogenesis of neovascular AMD.
