Trial Outcomes & Findings for ALLEVIATE Trial - A Phase 3 Trial in Subjects With Allergic Conjunctivitis (NCT NCT03494504)

NCT ID: NCT03494504

Last Updated: 2025-02-11

Results Overview

Subject-reported ocular itching score area under the curve from 10 to 60 minutes post allergen challenge using a 0 to 4 scale (0 = none, 4 = severe) was assessed. The least squares mean was derived from analysis of covariance of area under the curve with baseline as a covariate and treatment as a fixed effect The possible range for area under the curve least squares mean is 0 to 100, where a lower score is better.

PRIMARY outcome

Timeframe: Efficacy was assessed after a single dose; baseline was assessed approximately two weeks before dosing.

Population: Intent-to-treat population with observed data only

Subject-reported ocular itching score area under the curve from 10 to 60 minutes post allergen challenge using a 0 to 4 scale (0 = none, 4 = severe) was assessed. The least squares mean was derived from analysis of covariance of area under the curve with baseline as a covariate and treatment as a fixed effect The possible range for area under the curve least squares mean is 0 to 100, where a lower score is better.

SECONDARY outcome

Timeframe: Efficacy was assessed after a single dose; baseline was assessed approximately two weeks before dosing.

Population: Intent-to-treat population with observed data only

The number of within subject 2-point responders (2-point reduction in itch score from 20-60 minutes post-challenge) using a 0 to 4 scale (0 = least, 4 = most) from the 5-minute post-challenge itch score at baseline was assessed.
