Phase 2
Completed
Conditions
Blepharitis
Demodex Infestation
Meibomian Gland Dysfunction
Interventions
Drug: TP-03 Vehicle
Registration Number
NCT05454956
Lead Sponsor
Tarsus Pharmaceuticals, Inc.
Brief Summary

The purpose of this study is to compare the safety and efficacy of TP-03, 0.25%, an eyedrop, BID vs TID dosing regimens for the treatment of meibomian gland dysfunction in patients with Demodex lid infestation.

Detailed Description

This Phase 2a study is a randomized, two-arm, double-masked, multicenter, parallel pilot study to compare the safety and efficacy of two dosing regimens of TP-03, BID vs TID, for the treatment of meibomian gland dysfunction in patients with Demodex lid infestation. The primary objective of the study is to assess the safety and efficacy of two dosing regimens of TP-03, 0.25% from Day 1 to Day 85 in adult participants with meibomian gland dysfunction in the presence of Demodex infestation. Efficacy will be determined by assessing lower lid meibomian gland secretion, lid margin erythema, bulbar redness, tear breakup time, ocular surface staining, and dry eye symptoms. Safety will be determined by assessing adverse effects related to the treatment as well as evaluating any changes in visual acuity and slit lamp biomicroscopy from baseline.
