Evaluation of the Onset and Duration of Action of RX-10045 in Allergic Conjunctivitis

Phase 2
Completed
Conditions
Allergic Conjunctivitis
Interventions
Drug: Vehicle for RX-10045 arm
Registration Number
NCT01639846
Lead Sponsor
C.T. Development America, Inc.
Brief Summary

To purpose of this study is to establish the efficacy and safety of RX-10045 ophthalmic solution in alleviating the signs and symptoms of allergic conjunctivitis

Detailed Description

Allergies are relatively common among the general population. Ocular signs and symptoms include itching, discomfort, redness, chemosis, tearing, and eyelid swelling. Allergic reactions can vary from a mild, self-limiting disease, to a debilitating condition that significantly impairs the quality of life of allergen-sensitive individuals.

Currently approved treatments for ocular allergy reduce the signs and symptoms of the early phase reaction; however, evidence suggests that many patients suffer from the persistent late phase reaction. Manifestations of the late phase reaction occur 6 to 24 hours after allergen exposure and are characterized by an influx of acute inflammatory cells into the conjunctivae. Administration of anti-inflammatory agents decreases allergy signs and symptoms in both the early and late phase reactions.

RX-10045 has been shown to be efficacious in multiple pre-clinical dry eye disease models and in a pre-clinical model of allergic conjunctivitis. The objective of this clinical study is to assess the safety and efficacy of RX-10045 ophthalmic solution for the treatment of the signs and symptoms of allergic conjunctivitis induced in the Conjunctival Allergen Challenge Model of allergic conjunctivitis at 15 minutes and 8 hours after medication instillation. It is anticipated that RX-10045 has therapeutic potential for the treatment of allergic conjunctivitis and an acceptable risk-benefit profile.
