Trial Outcomes & Findings for Efficacy of AC-150 for the Treatment of Allergic Conjunctivitis in the Enviro-CAC™ Model (NCT NCT01134328)

NCT ID: NCT01134328

Last Updated: 2017-09-14

Results Overview

A treatment efficacy CAC was performed 15 minutes after drop instillation. Ocular itching was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of ocular itching score over both eyes was analyzed.

Participant Flow

Subjects were recruited from two sites in the US.

There were 83 subjects enrolled, 12 subjects discontinued, and 71 subjects completed the study. Participant flow and baseline characteristics are presented for the 83 subjects that met all inclusion criteria and none of the exclusion criteria and were randomized to receive AC-150 Combo, AC-150A 0.1%, AC-150B 0.005% or Vehicle

Timeframe: 7, 15, 20 minutes post-CAC

Population: Per protocol population

A treatment efficacy CAC was performed 8 hours after drop instillation. Episcleral Redness was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of episcleral redness score over both eyes was analyzed.

SECONDARY outcome

Timeframe: 7, 15, 20 minutes post-CAC

Population: Per protocol population

A treatment efficacy CAC was performed 15 minutes after drop instillation. Total redness was defined as the sum of the conjunctival, ciliary and episcleral redness scores, and was, thus, on a 0-12 scale, making the threshold for clinical significance a treatment difference of 3.0 units. Higher scores represent greater severity.

SECONDARY outcome

Timeframe: upon instillation, 1 minute and 2 minutes post instillation

Population: Intent to Treat (ITT). Number of analyzed subjects differ due to subject discontinuation during the study.

Subjects were asked to rate the comfort of the drop in each eye upon instillation, at 1 minute, and at 2 minutes after instillation of study medication. The assessment used a 10-point scale with 0 as very comfortable and 10 as very uncomfortable. Higher scores represent a worse outcome.
