A Prospective Study to Assess the Hypotensive Efficacy of Rho-Kinase Inhibitor AR-12286 Ophthalmic Solution 0.5% and 0.7% in Patients With Exfoliation Syndrome and Ocular Hypertension or Glaucoma

Completed · Phase 2

Conditions studied: Exfoliation Syndrome, Ocular Hypertension, Open Angle Glaucoma

In brief

Glaucoma is the world's the second leading cause of irreversible blindness. The World Health Organization (WHO) estimated the incidence of blindness due to glaucoma to be 4.4 million people worldwide in 2002. Intraocular pressure (IOP) is the sole proven modifiable risk factor for the development and progression of glaucomatous optic neuropathy. Medical therapy is aimed at lowering IOP in order to prevent or slow progression. Exfoliation syndrome (XFS) is the most common identifiable cause of open-angle glaucoma, affecting an estimated 60 to 70 million people worldwide. Approximately two-thirds of patients have disease in only one eye on clinical examination; however, XFS is detectable in the other eye with conjunctival biopsy. XFS is also a systemic disease, with effects on the cardiovascular and cerebrovascular systems. Patients with XFS are twice as likely to convert from ocular hypertension to glaucoma. Glaucoma in XFS is more severe than primary open angle glaucoma. There is greater diurnal IOP fluctuation, greater visual field loss and optic nerve head damage at the time of diagnosis, poorer response to medications, more rapid visual field progression and more frequent need for surgery. Because you meet eligibility criteria for our study, we ask for your consent to participate in the study described below. In brief, you will be taking an investigational drug (AR-12286, rho-kinase Inhibitor) at either 0.5% or 0.7% once a day for 6 months. This drug is currently being tested in patients with primary open-angle glaucoma, but not yet in glaucoma in exfoliation syndrome. Because of the mechanism of glaucoma in XFS and the mechanism of action of rho-kinase inhibitors, there is reason to think it would be more effective in eyes with XFS and glaucoma than in primary open-angle glaucoma (ordinary glaucoma). There will be a baseline and study day 1 visit, week 1 visit, month 1 and 3 visit, week 13 visit, month 6 visit and a week 25 visit; for a total of 7 office visits.
