Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Participants will receive a canalicular occlusion and will be followed for 3 months so that safety and effectiveness of the device may be evaluated.

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 (Actual)

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

22 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Male or female aged 22 or older complaining of ocular dryness who report having to use artificial tears or lubricants.

  2. Both of the following conditions:

    • Baseline symptoms score of 23 or higher on the OSDI questionnaire; and
    • OSDI Questionnaire has 3 or fewer responses of "not applicable"
  3. Basal tear secretion (Schirmer I Test with anesthesia) < 10mm/5 minutes (in one of the two eyes). The eye with the lower score is the study eye.
  4. Willing and able to comply with the study procedures and follow-up.
  5. Willing and able to provide informed consent.

Exclusion Criteria:

  1. Presence or history of chronic or current, acute ocular inflammation or infection, aside from mild blepharitis or inflammation associated with primary dry eye or disorders which are known to cause dry eyes (e.g. Sjrögens Syndrome).
  2. The presence of any lacrimal occlusion, ocular disorder, or condition in either eye, conjunctiva, or lacrimal system that, in the opinion of the investigator, would interfere with the interpretation of the study results (e.g., corneal transplant, routine ocular injections, recent ocular surgery, ectropion, surgical procedure such as cautery, or past canalicular surgery, significant corneal or conjunctival scarring, pterygium or nodular pinguecula; active ocular herpetic infection; lid or lacrimal cancer; clinically significant corneal dystrophy or other disorder which may cause rapid degeneration of visual acuity, such as anterior (epithelial) basement membrane corneal dystrophy, clinical keratoconus, or active, wet macular degeneration.
  3. Presence of - or unverified removal of - other canalicular occlusion devices.
  4. Chronic allergic rhinitis
  5. Allergic to study materials, supplies and medication.
  6. Contraindication to topical anesthesia.
  7. Actively using a topical medication (such as steroids and immunosuppressants) for which the use of a plug may cause complications, regardless of dosage adjustment.
  8. Participation in another ophthalmic clinical trial within three months prior to enrollment. Participant must also be willing to refrain from another ophthalmic study for the duration of the study.
  9. Co-existing health condition(s), either ocular or non-ocular that, in the judgement of the investigator could affect the safety or effectiveness of treatment, the compliance of the participant to the protocol, or other factors which may confound validity of study data collection or analysis. For example, participants who are pregnant or nursing, have pterygium, or uncontrolled blepharitis for which artificial lubricants do not provide relief are excluded. Unless post-menopausal or medically sterile (e.g hysterectomy, bilateral tubal ligation, bilateral oophorectomy), female participants must have a negative urine pregnancy test (UPT) on Day 0 of the study and should utilize a medically acceptable form of contraception over the course of the study.

  10. Use of drugs under any of the following conditions:

    • Change in dry eye medication (e.g., Restasis or Xiidra) within 60 days prior to enrollment (i.e., participant drug use must be stable prior to the study. They may not be enrolled if they began drug use within the past 60 days of assessment or if they intend to begin prescription drug use during the study); or
    • Systemic medication(s) (other than anti-histamines) that is known to cause ocular dryness (e.g. diuretics, anti-hypertensives, anti-depressants, hormone therapy) and whose dose of this medication(s) has not been stable within 30 days prior to enrollment. There must be no anticipated adjustments to the dose of these medications for the duration of the trial; or
    • Oral tetracyclines or azithromycin between enrollment and 30 days prior, unless their dosage will remain the same throughout the study; or
    • Topical ophthalmic antibiotics, anti-glaucoma medications, steroids, non-steroidal anti-inflammatory medications between enrollment and 30 days prior to enrollment, with the exception that patients who are newly prescribed short-term use (15 days or less) anti-inflammatories (e.g., corticosteroids) by the investigator during their screening visit may be included

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean change in basal tear secretion (Schirmer I test, with anesthesia) for designated study eye from baseline to Week 12
Time Frame: 3 months
Outcome reflects the volume of tears collected in the tear film over 5 minutes. A higher score reflects a larger tear film.
