Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Determine the ability of the TearScience™ LipiView™ II Ocular Surface Interferometer and the Keratograph® 5M to detect tear film stability utilizing Miebo® by examining potential differences in various tear film assessments before dosing Miebo® and at multiple timepoints post-Miebo® dosing

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. At least 18 years of age at the time of consent
  2. Able to provide written voluntary informed consent
  3. Must have a normal pre-corneal tear film in one or both eyes[MC4.1][AA4.2]
  4. Subjects cannot have instilled any topical ocular drops (including OTC lubricant drops) within 24 hours of the study visit.
  5. Able and willing to follow instructions, including participation in all trial assessments and visits

Exclusion Criteria:

  1. Have any clinically significant ocular surface slit-lamp findings in either eye and/or, in the opinion of the Investigator, have any findings that could interfere with trial parameters including:

    1. History of Stevens-Johnson syndrome
    2. Active blepharitis or lid margin inflammation
    3. DED secondary to scarring, irradiation, alkali burns, cicatricial pemphigoid, or destruction of conjunctival goblet cells (as with vitamin A deficiency)
    4. Abnormal lid anatomy causing incomplete eyelid closure
    5. Abnormal cornea shape (keratoconus)
    6. Corneal epithelial defect or significant confluent staining or filaments
    7. History of ocular malignancy
  2. Pterygium in either eye
  3. Use of any of the following ocular therapies in the study eye within 24 hours prior to Visit 1: Vuity®, VIZZ™, topical ocular steroid treatments, topical antibiotics, prescription dry eye therapy including varenicline nasal spray, over the counter dry eye therapy (such as artificial tears, re-wetting drops, or Lumify®), TrueTear™ device (intranasal tear neurostimulator), or topical anti-glaucoma medication
  4. Have active uncontrolled ocular allergies or ocular allergies that are expected to be active during the trial period
  5. Have undergone intraocular surgery or ocular laser surgery in the study eye within 3 months prior to Visit 1; have undergone refractive surgery in the study eye within 6 months prior to Visit 1
  6. Have worn contact lenses within 24 hours prior to Visit 1.
  7. Have active ocular or systemic infection (bacterial, viral, or fungal), including fever
  8. Female subjects who are pregnant, nursing, or planning a pregnancy
  9. Female subjects of childbearing potential who are not using an acceptable means of birth control; acceptable methods of contraception include hormonal (oral, implantable, injectable, or transdermal) contraception; mechanical (spermicide in conjunction with a barrier such as a diaphragm or condom) contraception; intrauterine device; or surgical sterilization of partner. For non-sexually active female subjects, abstinence may be regarded as an adequate method of birth control; however, if the subject becomes sexually active during the trial, she must agree to use adequate birth control as defined above for the remainder of the trial
  10. Have an uncontrolled systemic disease that, in the opinion of the Investigator, will interfere with the trial
  11. Have a known allergy and/or sensitivity to the investigational product or diagnostic substances (e.g. fluorescein) to be used in the study
  12. Are currently enrolled in any investigational or device study or have used Miebo® within 24 hours prior to Visit
