Dry Eye Disease

Brief summary

The purpose of this study is to evaluate the effect of treatment with 0.017% P-321 on Dry Eye Symptoms.

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.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline (Visit 2) to Day 29 (Visit 4) in the Subject-reported Dry Eye Symptom Questionnaire.Baseline to Day 29Dry 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.

Secondary

MeasureTime frameDescription
Change From Baseline (Visit 2) to Day 29 in Symptom Severity ScoresBaseline to Day 29Dry 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.
Change From Baseline to Day 29 in Fluorescein Staining of the Cornea.Baseline to Day 29Corneal 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.
Change From Baseline (Visit 2) to Day 29 in Symptom Frequency ScoresBaseline to Day 29Dry 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.
Number of Participants With at Least 20% Improvement in Symptoms From Baseline to Day 29Baseline to Day 29Improvement 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.
Change From Baseline (Visit 2) to Day 15 (Visit 3) in the Subject-reported Dry Eye Symptom Score.Baseline to Day 15Dry 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.
Change From Baseline to Day 29 in Lissamine Green Staining of the Conjunctiva.Baseline to Day 29Conjunctival 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.
