A Study to Assess the Effect of Rho-Kinase Inhibitor AR-12286 Ophthalmic Solution 0.5% and 0.7% in Patients With Chronic Angle-closure Glaucoma (ROCK - CACG)

April 23, 2015 updated by: Jessica Jasien, New York Glaucoma Research Institute

A Prospective Study to Assess the Hypotensive Efficacy of Rho-Kinase Inhibitor AR-12286 Ophthalmic Solution 0.5% and 0.7% in Patients With Chronic Angle-closure Glaucoma

To evaluate the ocular hypotensive efficacy of Rho kinase Inhibitor (AR-12286 0.5% and 0.7%) ophthalmic solutions in patients diagnosed with chronic angle-closure glaucoma treated for 6 months.

Secondary Outcome

Secondary objectives are:

  1. To evaluate the early effect of Rho kinase Inhibitor (AR-12286) in reducing intraocular pressure (IOP).
  2. To evaluate the long term effect of the drug on IOP.
  3. To determine if AR-12286 can be used as directed therapy for CACG, reducing or eliminating the structural blockage of the trabecular meshwork that leads to development of elevated IOP.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 85 years (ADULT, OLDER_ADULT)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Experimental: 0.5% Rho-Kinase Inhibitor
AR-12286 is a novel, potent Rho-kinase inhibitor developed by Aerie Pharmaceuticals, Inc., Bridgewater, NJ. It has single-digit nanomolar inhibitory activity against Rho-kinase in enzymatic inhibition assays. Mechanism-of action studies in monkeys demonstrate that AR-12286 lowers IOP primarily by increasing aqueous humor outflow through the trabecular meshwork Rho-kinase AR-12286 is well tolerated and produces clinically and statistically significant ocular hypotensive efficacy in patients with ocular hypertension and glaucoma. It is well tolerated by most patients and the only side effect was ocular hyperemia in a minority of subjects. It is currently in phase II testing.
