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

The objective of this study is to assess the safety and efficacy of Ocular Iontophoresis with Dexamethasone Phosphate 40 mg/mL 7.5 mA-min at 2.5 mA and Ocular Iontophoresis with Dexamethasone Phosphate 40 mg/mL 10.5 mA-min at 3.5 mA compared to placebo for the treatment of the signs and symptoms of dry eye.

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.

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
Sign: Corneal fluorescein staining after CAE exposure at Visit 5
Time Frame: Visit 5 (Day 7 ± 2 Days)
Corneal fluorescein staining after CAE exposure at Visit 5 as measured by the ORA scale.
Visit 5 (Day 7 ± 2 Days)
Symptom: Ocular discomfort during CAE exposure at Visit 5
Time Frame: Visit 5 (Day 7 ± 2 Days)
Symptom: Ocular discomfort during CAE exposure at Visit 5 as measured by ORA scale.
Visit 5 (Day 7 ± 2 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
Sign: Fluorescein staining at each visit over 3 weeks
Time Frame: 7 visits / 3 weeks
Fluorescein staining (each region) as measured by the ORA and NEI Scales at each of 7 visits over 3 weeks
7 visits / 3 weeks
Symptom: Ocular discomfort pre and post CAE
Time Frame: Visit 1 (Day -7 ± 2 Days), Visit 3 (Day 0), and Visit 5 (Day 7 ± 2 Days)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
