Trial Outcomes & Findings for Clinical Trial to Evaluate the Chronic Efficacy of OC-01 Nasal Spray on Signs of Dry Eye Disease (The MYSTIC Study) (NCT NCT03873246)

NCT ID: NCT03873246

Last Updated: 2022-06-08

Results Overview

The Schirmer's test measures the amount of tears produced by numbing the eye and placing a paper strip in the eye for 5 minutes and distance of wetting was recorded following treatment with OC-01 or placebo. Schirmer's test scores range from 0-35 mm where a higher score is indicative of a better outcome.

A standardized grading system of 0-3 is used for each of the five areas of the cornea (inferior, superior, nasal, temporal, central). Grade 0 will be specified when no staining is present. The total score ranges from 0-15. Lower scores indicate improvement.
