About this study

This Phase 4 study is a prospective, multicenter, randomized, vehicle-controlled, double-masked, two-arm, parallel treatment clinical trial of participants who have Demodex blepharitis and are current daily wear soft contact lenses wearers. The primary outcome measure is the reduction of collarettes at Day 43. The secondary outcome measures are the reduction of eyelid margin erythema at Day 43; subject-reported comfortable contact lens daily wear time; and total contact lens wear time. Safety will be determined by assessing adverse effects related to study drug administration as well as evaluating any clinically significant changes from baseline in visual acuity and slit lamp biomicroscopy findings.
