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 is a multi-center, randomized, double-masked, placebo-controlled, parallel group Phase 2b trial designed to evaluate symptoms and signs in subjects with mild to moderate dry eye disease. Eligible patients, will be treated with placebo during 2-week placebo run-in period. Subjects will then be randomly assigned in a double-masked, 1:1 ratio to either 0.017% P-321 Ophthalmic Solution or placebo TID for 28 days. This study is designed to evaluate the changes in symptoms. Safety will be assessed throughout the study by adverse events.

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

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.

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 (Visit 2) to Day 29 (Visit 4) in the Subject-reported Dry Eye Symptom Questionnaire.
Time Frame: Baseline to Day 29
Dry Eye symptoms were obtained using the Symptom Assessment in Dry Eye (SANDE) questionnaire. The questionnaire utilizes separate Visual Analog Scales (VAS) for the frequency and the Severity of symptoms. The scores range from 0 to 100 where 0 = Rarely or Very Mild, and 100 = All the Time or Very Severe for the Frequency and Severity of the symptoms, respectively. The Global Score as reported in the Primary Outcome is obtained by taking the square root of the product of the frequency score multiplied by the severity score. Negative change from baseline indicates improvement.
Baseline to Day 29

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 (Visit 2) to Day 29 in Symptom Frequency Scores
Time Frame: Baseline to Day 29
Dry Eye symptom frequency was obtained using the Symptom Assessment in Dry Eye (SANDE) questionnaire. The questionnaire utilizes a 100 mm horizontal Visual Analog Scale (VAS). The scores range from 0 to 100 where 0 = Rarely and 100 = All the Time. A negative change from baseline indicates improvement.
Baseline to Day 29
Change From Baseline (Visit 2) to Day 29 in Symptom Severity Scores
Time Frame: Baseline to Day 29
Dry Eye symptom severity was obtained using the Symptom Assessment in Dry Eye (SANDE) questionnaire. The questionnaire utilizes a 100 mm horizontal Visual Analog Scales (VAS). The scores range from 0 to 100 where 0 = Very Mild and 100 = Very Severe. A negative change from baseline indicates improvement.
Baseline to Day 29
Change From Baseline to Day 29 in Fluorescein Staining of the Cornea.
Time Frame: Baseline to Day 29
Corneal staining was performed to grade the corneal epithelial cell injury as measured by fluorescence using slit lamp examination. The staining was graded with the NEI scale. The corneal surface is divided into 5 corneal regions (1, Central; 2, Inferior; 3, Nasal; 4, Temporal; 5, Superior). The scores for each of these 5 regions ranged from 0 to 3 (0=no staining; 1=staining with low density; 2=staining with moderate density; 3=staining with severe density). The total staining score (sum of all regions, maximal score =15) is reported. A negative change from baseline indicates improvement.
Baseline to Day 29
Change From Baseline to Day 29 in Lissamine Green Staining of the Conjunctiva.
Time Frame: Baseline to Day 29
Conjunctival staining was performed to grade the conjunctival epithelial cell injury as measured by Lissamine Green using slit-lamp examination. The staining was graded with the NEI scale. The bulbar conjunctival surface is divided into 6 regions (1, Temporal; 2 Temporal Superior; 3, Temporal Inferior; 4, Nasal Superior; 5, Nasal Inferior; 6, Nasal). The scores for each of these 6 regions ranged from 0 to 3 (0=no staining; 1=staining with low density; 2=staining with moderate density; 3=staining with severe density). The total staining score (sum of all regions, maximal score =18) is reported. A negative change from baseline indicates improvement.
Baseline to Day 29
Number of Participants With at Least 20% Improvement in Symptoms From Baseline to Day 29
Time Frame: Baseline to Day 29
Improvement in symptoms was evaluated using the Symptom Assessment in Dry Eye (SANDE) questionnaire. The questionnaire utilizes separate Visual Analog Scales (VAS) for the frequency and the Severity of symptoms. The scores range from 0 to 100 where 0 = Rarely or Very Mild, and 100 = All the Time or Very Severe for the Frequency and Severity of the symptoms, respectively. The Global Score is obtained by taking the square root of the product of the frequency score multiplied by the severity score. Lower scores indicate improvement in symptoms.
Baseline to Day 29
Change From Baseline (Visit 2) to Day 15 (Visit 3) in the Subject-reported Dry Eye Symptom Score.
Time Frame: Baseline to Day 15
Dry Eye symptoms were obtained using the Symptom Assessment in Dry Eye (SANDE) questionnaire. The questionnaire utilizes separate Visual Analog Scales (VAS) for the frequency and the Severity of symptoms. The scores range from 0 to 100 where 0 = Rarely or Very Mild, and 100 = All the Time or Very Severe for the Frequency and Severity of the symptoms, respectively. The Global Score as reported in the Primary Outcome is obtained by taking the square root of the product of the frequency score multiplied by the severity score. A negative change from baseline indicates improvement.
