CyclASol for the Treatment of Moderate to Severe Dry-eye Disease (DED)
A Phase 2, Multi-center, Randomized, Double-masked, Placebo (Vehicle)-Controlled Clinical Study With an Open Label Comparator Arm to Assess the Efficacy, Safety and Tolerability of Topical CyclASol® for Treatment of Dry Eye Disease

Detailed Description
This phase 2 study explored the safety, efficacy and tolerability of two CyclASol concentrations as one drop twice daily versus vehicle (placebo). In addition to the masked vehicle control arm, an open-label comparator arm consisting of Restasis was included.
The study explored a range of signs and symptoms of DED to gain an understanding of the possible treatment effects in comparison to vehicle and estimation of effect sizes. In line with current treatment guidelines, the proposed phase 2 population consisted of patients suffering from moderate to severe DED.
The primary treatment comparisons in this study were between the two CyclASol concentrations versus vehicle for the sign variable total corneal fluorescein staining and the symptom variable dryness severity visual analogue scale at day 113. All other comparisons between treatments groups were considered secondary analyses.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline (Visit 1) in Total Corneal Fluorescein Staining at 113 Days
Time Frame: Baseline to 113 Days
|
The primary analysis and objective of the study was to compare the two CyclASol groups versus vehicle (all blinded treatment arms) for one sign and one symptom endpoint.
The open label active comparator arm was not included in the primary analysis to reduce the number of comparisons.
The sign endpoint was the change from baseline in total corneal fluorescein staining at day 113.
The cornea is divided into five regions: central, superior, inferior, nasal and temporal.
Each region is graded from 0-3 based on the National Eye Institute scale, where 0 indicates no staining and 3 maximal staining.
The total score is the sum of all these regions.
The maximum score for each eye is 15.

Baseline to 113 Days

Change From Baseline (Visit 1) in Dryness Severity Visual Analog Scale (VAS) at 113 Days
Time Frame: Baseline to 113 Days
|
The primary analysis and objective of the study was to compare the the two CyclASol groups versus vehicle (all blinded treatment arms) for one sign and one symptom endpoint.
The open label active comparator arm was not included in the primary analysis to reduce the number of comparisons.
Furthermore, the open label character could have had an impact on patient reported outcomes.
The symptom endpoint was the change from baseline in severity of dryness VAS at Day 113.
Dryness severity was rated from 0 to 100%, where 0% corresponds to "no dryness" and 100% corresponds to "maximum dryness".
