Ketotifen/Naphazoline Ophthalmic Solution in the Conjunctival Allergen Challenge Model of Acute Allergic Conjunctivitis.
October 5, 2020 updated by: Bausch & Lomb Incorporated
A Multi-center, Double-masked, Randomized, Placebo-controlled Evaluation of the Onset and Duration of Action of KetoNaph Ophthalmic Solution in the Conjunctival Allergen Challenge (CAC) Model of Acute Allergic Conjunctivitis.
The purpose of this study is to establish the safety and efficacy of ketotifen/naphazoline ophthalmic solution compared to vehicle and its individual components in alleviating the signs and symptoms of conjunctival allergen challenge (CAC)-induced allergic conjunctivitis.
