About this study

Official title: The Effects of Cyclosporin A Emulsion, (Restasis), on the Ocular Surface in Response to Low Humidity Environment in Patients With Dry Eye

This study will test that hypothesis that topical administration of the FDA approved immunomodulatory agent cyclosporin A emulsion will minimize irritation and ocular surface disease that results from a short term low humidity environmental stress

Read the detailed description

This is a pilot study designed to evaluate the effect of two conventional dry eye therapies, artificial tears to hydrate and cyclosporine A as an anti-inflammatory, on the irritation symptoms and ocular surface disease of dry eye patients who will be exposed to a low humidity environment for 90 minutes. Patients with dry eye will be enrolled in this study and complete a validated symptom questionnaire and then undergo a complete ocular surface and tear examination to characterize their disease. Enrolled subjects will be exposed to a low humidity environment at the initial evaluation prior to any treatment and will be exposed to a low humidity environment for a second time. They will be randomized to receive either artificial tears or 0.05% cyclosporine A emulsion drop four times a day for 6 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Corneal Fluorescein Staining

    The mean difference in corneal staining using the adjusted CCLR global staining score before and after the environmental challenge at visits baseline and Visit 3/Day 42 when patients were subjected to a 90-minute low humidity stress. Corneal fluorescein staining was graded 0-100 in 5 zones on the cornea. The scores ranged from 0 (minimum) to 500 (maximum). A higher score indicates there was greater cornea disease induced by the low humidity stress on Day 42

    Measured: 6 weeks

Secondary outcomes (1)
  1. Eye Irritation Symptoms

    The mean difference in subject's scoring of eye irritation symptoms using a VAS (visual analog scale) questionnaire before and after the environmental challenge after treatment at Visit 3/Day 42 when patients were subjected to a 90-minute low humidity stress. Symptoms were graded on a 4 question VAS 0-5 for each question, with scores summed for all questions for a total score that ranges from 0 (minimum) to 20 (maximum) for the pre and post challenge questionnaires. The outcome measure is the difference in the post to pre total score ranging from -20 (maximum improvement) to 20 (maximum worsening). A minus difference indicated the subject had lower irritation symptoms following the lower humidity challenge, while a positive difference indicated the subject had greater irritation following the low humidity challenge on Day 42.

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Cyclosporin 0.05% emulsion and Endura, Refresh artificial tears in people with Dry Eye, run by Baylor College of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Feb 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Corneal Fluorescein Staining (time frame: 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02199964, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2020.
