Abstract

PURPOSE:

To evaluate the effectiveness of bepotastine besilate ophthalmic solutions 1.0% and 1.5% compared with placebo at reducing ocular itching and conjunctival hyperemia in the conjunctival allergen challenge (CAC) model of allergic conjunctivitis.

DESIGN:

Prospective, double-masked, randomized, placebo-controlled, phase 3 CAC clinical trial.

METHODS:

This multicenter trial enrolled 130 subjects with a clinical history of allergic conjunctivitis who were randomized to bepotastine besilate ophthalmic solution 1.0%, 1.5%, or 0.0% (placebo). One drop of test agent was instilled bilaterally before a CAC test evaluating responses at 15 minutes, 8 hours, or 16 hours after test agent instillation. Primary efficacy outcomes were unit improvements relative to placebo in mean scores for ocular itching and conjunctival hyperemia, each graded on 0- to 4-unit scales.

RESULTS:

Reductions of 1.2 units or more in mean ocular itching scores at all time points for both bepotastine besilate ophthalmic solutions 1.0% and 1.5% were observed at onset of action and 8-hour duration-of-action CAC tests (P < .0001). Statistically significant reductions in conjunctival hyperemia (P < or = .0125) were observed for bepotastine besilate ophthalmic formulations only at the onset of action CAC test.

CONCLUSIONS:

Bepotastine besilate ophthalmic solutions 1.0% and 1.5% both substantially decreased CAC-induced ocular itching for at least 8 hours after dosing. Reductions in conjunctival hyperemia after a CAC, although statistically significant for bepotastine besilate ophthalmic solutions 1.0% and 1.5% compared with placebo when assessed at 15 minutes after dosing, were modest.
