Study Summary

The purpose of this study is to compare the safety and efficacy of TP-03, 0.25%, an eyedrop, to its vehicle control for the treatment of blepharitis due to Demodex, a microscopic mite frequently found in human hair follicles. The hypothesis for the study is the proportion of participants cured at Day 43 with treatment by TP-03, 0.25%, is greater than the proportion cured by treatment with its vehicle.

Primary Outcome

The proportion of participants cured where cure is defined as 0-2 lashes with collarettes on the upper eyelid of the analysis eye. The primary outcome analysis is the combined result from 20 analyses each with missing data imputed. Missing data were imputed per the method described in the SAP. The least square mean is computed from the result of the 20 analyses with imputed missing values.
