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

NCT ID: NCT00536016

Last Updated: 2010-09-21

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 36 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2007-09-30
• Study Completion Date: 2009-12-31

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.

Eligibility Criteria

Inclusion Criteria

• Best corrected visual acuity in the study eye between 5 and 7 letters inclusive using and ETDRS chart (Snellen equivalent of appx. 20/800 to 20/40.
• Subfoveal choroidal neovascularization (CNV) due to AMD.
• Total area of the lesion (including blood, neovascularization and scar/atrophy) must be ≤ 12 DA, of which at least 25% must be active CNV.
• For patients with occult or non classic CNV; there must be the presence of subretinal hemorrhage (but still comprising no more than 50% of the lesion) and/or documented evidence of three or more lines of vision loss (ETDRS or equivalent) during the previous 12 weeks.
• Clear ocular media and adequate pupillary dilatation to permit good stereo fundus photography for screening.
