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

Previous studies showed that dexamethasone and loteprednol topical drops have led to favorable results. However, the requirement of frequent instillation of drops by the patients is problematic causing discomfort and blurring of vision and requires remembering and dexterity for instillation, poor compliance is not uncommon. In addition Investigators believe that instillation of drops disturbs the homeostasis of the natural tear film due to physical and chemical trauma due to large drop volume (50 microliters) hammering on the eye surface (which can only hold 7 to 10 microliters). Particularly washing away of the mucin layer that holds all the "good ingredients" in the tears is harmful to the ocular surface. Therefore, "dropless" treatment of dry eye is desirable.

Dextenza® (dexamethasone ophthalmic insert, Ocular Therapeutix Inc., Bedford, MA) is a corticosteroid intracanalicular insert approved by US-FDA in November 2018 for the treatment of post-surgical ocular inflammation and pain. It is inserted into the lower lacrimal punctum and into the canaliculus. A single insert releases a 0.4 mg dose of dexamethasone for up to 30 days following insertion. Dextenza® is resorbable and does not require removal. Investigators hypothesize that Dextenza® could mimic short-term topical steroid use in a tapering manner in patients with clinically significant dry eye and show efficacy in improving its symptoms and signs, as was previously shown with other steroid preparations. If proven, the use of Dextenza® may shift paradigms in the management of the clinically significant ocular surface disease. To test this hypothesis, investigators propose to study the effects of Dextenza® in the treatment of clinically significant dry eye.

Presence of significant symptoms defined as 30mm or higher score of (1) eye dryness, or (2) eye fatigue, or (3) eye discomfort as measured using VAS, in both eyes. At the baseline visit, the most bothersome symptom (of the three) will be determined and used as the main symptom outcome measure throughout the study.

Exclusion Criteria:

A patient who meets any of the following criteria will be excluded from the study:

  • Use of Contact lenses within 1 week of screening visit or during the study
  • Any ocular surgery (including tear duct cauterization) within the 3 months

  • Pregnancy, nursing or intention of pregnancy or nursing in the study period.
  • Monocular patients
  • Uncontrolled systemic disease (defined as frequent or recent change in the medication regimen)
  • Patients who are currently on with stable doses of oral steroids, topical cyclosporine or lifitigrast, topical tacrolimus or pimecrolimus are eligible as long as there has been no change in the dose in the last 3 months
  • Patients who are on topical steroids (With exception of rescue medication) (Patients who have used steroids recently but have been off for at least 2 weeks will be eligible.)
  • Current enrollment in any other investigational drug or device study or participation of study within 30 days of baseline visit.

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
Efficacy Endpoint as Assessed by Dry Eye Sign Using Ocular Surface Scale (OSS)
Time Frame: 28 days

OSS will be graded according to the Sjögren's International Collaborative Clinical Alliance (SICCA) grading system. Maximum possible fluorescein score (the punctate epithelial erosions grade + any extra points for modifiers [central staining, confluent staining, and filaments]) will be 6 and minimum of 0. Maximum possible conjunctival staining score (the punctate epithelial erosions grade on the temporal and nasal sides) will be 6 and minimum of 0. The total possible maximum OSS, derived by summing the corneal and conjunctival scores, will be 12 for each eye, and minimum OSS will be 0. Higher corneal, conjunctival, and staining scores represent worse outcomes.

The difference between the average corneal staining in the treated arm versus the average corneal staining in the sham arm will be compared statistically.
28 days
Patient Reported Symptom
Time Frame: 28 Days
(1)eye dryness, (2)eye discomfort, or (3)eye fatigue will be measured using visual analogue scale (0 to 100). The difference between the average bothersome symptom in the treated arm versus the average most bothersome symptom in the sham arm will be compared statistically. Higher VAS scores indicate worse eye dryness, discomfort, or fatigue.
28 Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Subjects Achieving 2 Severity Grade Improvement in Corneal Staining
Time Frame: 42 days
Corneal staining responder analysis. Responder is defined as two full severity grade improvement in corneal staining. The percentage of subjects achieving two severity grades improvement in corneal staining (responders) in the treated arm versus sham arm will be compared statistically.
42 days
Percentage of Subjects Achieving Improvement in Their Most Bothersome Symptom
Time Frame: 42 days
Symptom responder analysis. Responder is defined as 30% or more improvement in the most bothersome symptom (VAS score is decreased by 30 points or more). The percentage of subjects achieving a 30% improvement in their most bothersome symptom (responders) in the treated arm versus the sham arm will be compared statistically.
42 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
