Efficacy and Safety of AL-4943A Ophthalmic Solution in Patients With Allergic Conjunctivitis Using the Conjunctival Allergen Challenge (CAC) Model

Allergic Conjunctivitis Clinical Trial

Official title:
A Multi-Center, Randomized, Double-Masked, Vehicle and Active Controlled, Parallel-Group Efficacy and Safety Study of AL-4943A Ophthalmic Solution, 0.77% in Patients With Allergic Conjunctivitis Using the Conjunctival Allergen Challenge (CAC) Model

Clinical Trial Summary

The purpose of this study was to assess the safety and efficacy of AL-4943A ophthalmic solution for the treatment of ocular itching associated with allergic conjunctivitis using the Conjunctival Allergen Challenge (CAC) model.

Clinical Trial Description

This study consisted of 5 Visits. Eligible patients underwent allergy testing using the Conjunctival Allergen Challenge (CAC) model, which reproduces the signs and symptoms of Seasonal Allergic Conjunctivitis by replicating the natural disease process. Patients demonstrating a positive reaction to the CAC at Visit 1 (screening) and Visit 2 (confirmatory) were randomized to treatment at Visit 3 (Day 0). The test article was instilled at Visit 3, with treatment efficacy CAC performed at 24 hours duration of action. The test article was instilled again at Visit 4 (Day 14), with treatment efficacy CAC performed at 16 hours duration of action. The test article was instilled a final time at Visit 5 (Day 21), with treatment efficacy performed at onset of action. ;
