Trial Outcomes & Findings for DNase Treatment for Dry Eyes (NCT NCT02193490)

NCT ID: NCT02193490

Last Updated: 2020-01-18

Results Overview

Corneal staining score as measured by Rose Bengal (RB) dye staining using National Eye Institute (NEI) 1995 workshop grading scale. The dye was applied to each eye and a slit lamp was used to observe corneal staining. The NEI scale relies on a chart that divides the cornea into 5 sections and assigns a value from 0 (absent) to 3 (severe) to each section, based on the density of punctate staining, final staining score being the sum of individual section scores, for a range of 0 (minimum) -15 (maximum) points. Complete corneal staining clearance with RB dye defined as a score of 0 indicating the best outcome.

PRIMARY outcome

Timeframe: Between baseline and at 8 weeks of treatment

Ocular Surface Disease Index (OSDI), a 12-item questionnaire, assesses symptom of ocular irritation in dry eye disease (DED) and how it affects functioning related to vision in the past week. It has 3 subscales: ocular symptoms, vision-related function, and environmental triggers. Patients rate their responses on 0 to 4 scale with 0 being "none of the time" and 4 being "all of the time." OSDI score range from 0-100 with score 0-12 being normal, 13-22 being mild DED, 23-32 being moderate DED, and \>33 being severe DED. OSDI=\[(sum of scores for questions answered)×100\]/\[(total questions answered)×4\]

OTHER_PRE_SPECIFIED outcome

Timeframe: Between baseline and 8-weeks of treatment

The presence of mucoid debris/strands over the ocular surface was assessed and the amount graded as the absence of mucoid debris (0) or presence of mucoid debris (1+, 2+ or 3+) with a bigger number indicating greater presence of mucoid debris with "3+" implying presence of the highest amount of mucoid debris and indicating the worst outcome.
