Effects of Xiidra on Closed Eye Tear Film Leukocytes in Dry Eye Disease

A Phase 4 interventional study of Lifitegrast in Ocular Discomfort, Ocular Inflammation and Dry Eye, sponsored by University of Alabama at Birmingham. Withdrawn. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-05-17.

Registry
Dry Eye Syndromes — the first condition term the registry derived for this study.
ClinicalTrials.gg
Keratoconjunctivitis Sicca
Why
  1. The study's listed conditions name Keratoconjunctivitis Sicca, a narrower term within Dry Eye Syndromes.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Every night during sleep, there is an accumulation of white blood cells in the closed eye. The closed eye white blood cells are predominantly neutrophils, but there is a small population (3%) of T cells. The effects of these closed eye white blood cells on dry eye disease pathogenesis have yet to be fully elucidated, but preliminary evidence suggests that closed eye neutrophils may have an associated hyperactivity and increased degranulation in dry eye disease that could contribute to epithelial instability. As an anti-T cell therapy, Xiidra offers an opportunity to better understand how the closed eye white blood cells are recruited and activated. This study also seeks to verify the proposed mechanism of action.

Accepts healthy volunteers
Yes

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Able to understand and sign an and HIPAA privacy document
  • Greater than 18 years of age at time of informed consent
  • Able and willing to follow protocol instructions
  • Capable of performing at-home eye wash
  • Must be willing to drop off samples and comply with study visit procedures
  • For contact lens wearers, must wear lenses at least four hours per day, four days per week

Exclusion criteria

Exclusion Criteria:

  • Current cigarette smokers
  • Current participation in any drug or device study. If subjects choose to participate in another investigational drug or device study, they will be discontinued from this study protocol.
  • Current pregnancy or nursing as indicated by self-report. While not a safety issue, pregnancy or nursing influences the biochemical composition of the tear film.
  • Any systemic health conditions that alter tear film physiology
  • A history of ocular surgery within the past 12 months
  • Any active ocular infection or inflammation
  • Any present use of Accutane or ocular medications
  • Any history of significant adverse reaction to lifitegrast or other components of the drug product, or to the use of lifitegrast or other components of the drug product
  • Any prior exposure to lifitegrast.
  • For normal and dry eye subjects, any history of contact lens wear within the past three months.
  • For contact lens wearers, any change of soft contact lens brand or care solutions within 30 days prior to screening or any anticipation of changing current type/brand of contact lenses or care solutions throughout the 84 day study
  • Any condition, which in the examiner's opinion, may put the subject at significant risk, confound study results, or interfere with their participation in the study.
Terms in these criteria, in plain language(3)

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change from baseline in the total number of T cells recovered from the closed eye to day 84

    Subjects will be trained and required to collect their closed eye tears at home, using a gentle saline rinse of the ocular surface. Enumeration of recovered T cells will be performed by flow cytometry.

    Time frame: Baseline to day 84

Secondary outcomes

  1. Change from baseline in the total number of neutrophils recovered from the closed eye to day 84.

    Subjects will be trained and required to collect their closed eye tears at home, using a gentle saline rinse of the ocular surface. Enumeration of recovered neutrophils will be performed by flow cytometry.

    Time frame: Baseline to day 84.
