Study 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.

Read the 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.

  • Have used systemic antihistamines within 30 days of Day 1
  • Have used artificial eyelashes, eyelash extensions, or had other cosmetic eyelash or eyelid procedures within 7 days of Day 1 or be unwilling to forego their use during the study

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Treatment Emergent Adverse Events (TEAEs)

    TEAEs related (definitely or potentially) to treatment summarized by MedDRA preferred term. TEAEs related (definitely or potentially) to treatment summarized by MedDRA preferred term.

    Time frame: 85 days

Secondary outcomes

  1. Change from baseline in lower lid meibomian gland secretion score

    For 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).

    Time frame: 85 days

  2. Change from baseline in lid margin erythema.

    Erythema 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.

    Time frame: 85 days

  3. Change from baseline in tear breakup time assessed via slit lamp

    Tear breakup time will be assessed via slit lamp examination and timed in seconds to two significant digits.

    Time frame: 85 days
