February 23, 2016 updated by: Alcon Research

Evaluation of Clinical Outcomes Following Treatment With Systane® Balance in Dry Eye Subjects With Lipid Deficiency

The purpose of this study is to demonstrate the superior efficacy of Systane® Balance over Preservative-Free 0.9% Saline following 35 days of QID (4 times a day) dosing in treating dry eye subjects with lipid deficiency.

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

This study consisted of 4 visits conducted during 3 sequential phases: the Run-in Phase (which included a screening visit and run-in period), Treatment Phase I and Treatment Phase II. In Phase I, subjects were randomized to either Systane® Balance or Saline and dosed 4 times a day for 35 days. In Phase II (Day 35-90) subjects continued to dose with their assigned product on an as-needed basis.

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
Change From Baseline in TFBUT at Day 35
Time Frame: Baseline (Day 0), Day 35
TFBUT (the time required for dry spots to appear on the corneal surface after blinking) was assessed by the investigator using ophthalmic dye and a biomicroscope and measured in seconds. Subjects were dosed in the office 1 hour ±10 minutes prior to TFBUT assessment. A shorter TFBUT indicates a higher likelihood of dry eye symptoms. A positive change indicates an improvement in TFBUT. One eye (study eye) contributed to the analysis.
Baseline (Day 0), Day 35

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
Change From Baseline in TOSS Score at Day 35
Time Frame: Baseline (Day 0), Day 35
The TOSS score (a cumulative cornea and conjunctival staining score) was assessed by the investigator using ophthalmic dye and a biomicroscope. Three areas of the ocular surface were graded for dryness on a 0-5 scale (0=Absent, 5=Severe), with a resultant overall score of 0-15. A negative change indicates an improvement in dry eye-related staining. One eye (study eye) contributed to the analysis.
Baseline (Day 0), Day 35
Change From Baseline in OSDI Score at Day 35
Time Frame: Baseline (Day 0), Day 35
The OSDI is a 12-item quality of life questionnaire designed to assess ocular surface symptoms, their severity, and their impact on the subject's ability to function. Each item was scored by the subject on a 0-4 Likert-type scale (0=None, 4=All of the Time), with a resultant overall score of 0-100 (0=no disability, 100=complete disability). A negative change number represents a perceived improvement in ocular health.
Baseline (Day 0), Day 35
Change From Baseline in IDEEL Treatment Effectiveness Score at Day 35
Time Frame: Baseline (Day 0), Day 35
The IDEEL is a 10-item questionnaire designed to assess the subject's general satisfaction with treatment use. The subject responded to treatment effectiveness questions (Questions 2-5) using a 0-4 Likert-type scale, where 0=None of the time and 4=All of the time. The IDEEL treatment effectiveness score was calculated as the sum of the responses from Questions 2-5 divided by the number of questions (2-5) answered, multiplied by 25, for a resultant overall score of 0-100. A positive change number represents perceived improvement.
Baseline (Day 0), Day 35
Change From Baseline in IDEEL Treatment Inconvenience Score at Day 35
Time Frame: Baseline (Day 0), Day 35
The IDEEL is a 10-item questionnaire designed to assess the subject's general satisfaction with treatment use. The subject responded to treatment inconvenience questions (Questions 6, 8-10) using a 0-4 Likert-type scale, where 0=All of the time and 4=None of the time. The IDEEL treatment inconvenience score was calculated as the sum of the responses from Questions 6, 8-10 divided by the number of questions (6, 8-10) answered, multiplied by 25, for a resultant overall score of 0-100. A positive change number represents perceived improvement.
Baseline (Day 0), Day 35
