Brief summary

The purpose of this study is to evaluate and compare the effect of two dosing regimens, BID versus TID dosing, of an Exploratory Vehicle (EV) on meibomian gland dysfunction (MGD) in patients with Demodex lid infestation.

Detailed description

This is a prospective, randomized controlled, three-arm, investigator- and interpreter-masked study. This study is intended to compare the effect of two dosing regimens of an exploratory vehicle on meibomian gland dysfunction (MGD) in participants with Demodex lid infestation. Approximately 12 participants will be enrolled in each arm. The administration period will last for approximately 85 days.

Interventions

DRUGVehicle of TP-03

The Exploratory Vehicle is the vehicle of TP-03 (lotilaner ophthalmic solution, 0.25%)

Treatment Emergent Adverse Events (TEAEs)85 daysTEAEs related (definitely or potentially) to treatment summarized by MedDRA preferred term. TEAEs related (definitely or potentially) to treatment summarized by MedDRA preferred term.

Secondary

MeasureTime frameDescription
Change from baseline in lower lid meibomian gland secretion score85 daysFor each of the 15 glands expressed, secretion characteristics will be graded via slit lamp examination on a scale of 0 to 3 (3=clear liquid secretion; 2=cloudy liquid secretion; 1=granularly opaque liquid secretion to inspissated/toothpaste consistency; and 0=no secretion).
Change from baseline in lid margin erythema.85 daysErythema of the eyelid margin will be assessed via slit lamp examination and graded on a scale of 0 (normal) to 3 (severe) for the upper and lower eyelids of each eye.
Change from baseline in tear breakup time assessed via slit lamp85 daysTear breakup time will be assessed via slit lamp examination and timed in seconds to two significant digits.
