Trial Outcomes & Findings for Evaluation of the Efficacy of OC-01 Nasal Spray on Signs and Symptoms of Dry Eye Disease (NCT NCT03636061)

NCT ID: NCT03636061

Last Updated: 2021-10-25

Results Overview

The primary end point was the change in anesthetized Schirmer's Test Score (STS) from baseline to 28 days in the study eye following treatment with OC-01. Schirmer's test score from 0-35 mm where a higher score is indicative of a better outcome.

PRIMARY outcome

Timeframe: 28 Days [Visit 1 (baseline) and Visit 5 (28 days)]

Population: Subjects in ITT-LOCF population

The primary end point was the change in anesthetized Schirmer's Test Score (STS) from baseline to 28 days in the study eye following treatment with OC-01. Schirmer's test score from 0-35 mm where a higher score is indicative of a better outcome.

SECONDARY outcome

Timeframe: 28 days [Visit 1 (baseline and Visit 5 (28 days)]

Population: Subjects in the ITT-LOCF population. The overall number of participants is different because these outcomes were assessed ar different visits 7 days apart and some subjects were not able to attend the Day 21 visit.

Change in Eye Dryness Score from baseline to 28 days. Eye Dryness (EDS) on a Visual Analogue Scale (VAS) from 0 (no discomfort) to 100 (maximum discomfort) millimeters where a lower score is indicative of a better outcome.
