Trial Outcomes & Findings for Evaluation of P-321 Ophthalmic Solution Compared to Placebo in Subjects With Dry Eye Disease (NCT NCT02831387)

NCT ID: NCT02831387

Last Updated: 2018-10-11

Results Overview

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.

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.

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.

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.
