Brief summary

The objective of this study is to compare the safety and efficacy of two different concentrations of ST-100 Ophthalmic Solution to placebo (vehicle) for the treatment of the signs and symptoms of dry eye.

Detailed description

This is a Phase 2, multi-center, double-masked, randomized, placebo-controlled clinical study. Subjects will be randomized to one of the following treatment arms at Visit 2 (Day 1): * Low dose ST-100 Ophthalmic Solution: 1 drop twice daily (BID) in each eye * High dose ST-100 Ophthalmic Solution: 1 drop BID in each eye * Placebo Ophthalmic Solution (Vehicle): 1 drop BID in each eye Approximately 150 subjects will be randomly assigned to one of the three groups (1:1:1) to receive either ST-100 Ophthalmic Solution or placebo solution as topical ophthalmic drops administered bilaterally BID for 4 weeks. Subjects, Sponsor, Contract Research Organization (CRO), and site personnel will be masked to treatment assignment. The clinical hypotheses for this study is that low dose and high dose ST-100 Ophthalmic Solution twice daily (BID) is superior to its vehicle (BID) for the primary endpoints of signs and symptoms of dry eye.

The scale is used to evaluate 3 corneal regions. Staining in each region is graded 0 to 4 where 0 means no staining, and 4 means worst staining. Higher score indicates more staining. The scoring reported ranges from 0-12. Mean change from baseline was calculated.

Change From Baseline in Fluorescein Staining in Conjunctival Sum - Both Eyes Together

The fluorescein staining is graded with the Ora Calibra® Corneal and Conjunctival Staining Scale. The scale is used to evaluate inferior, superior, central, temporal, and nasal region. Staining in each region is graded 0 to 4 where 0 means no staining, and 4 means worst staining. Higher score indicates more staining. The corneal sum score is the sum of scores from the inferior, superior, and central regions (min 0, max 12). The conjunctival sum score is the sum of scores from the nasal and temporal regions (min 0, max 8). The total eye score is the sum of scores from all five regions (min 0, max 20). The average values of both eyes assessment were reported (min 0, max 20).

Change From Baseline in Ocular Discomfort Scale (Ora Calibra Scale) During the CAE - Area Under the Curve

Ocular Discomfort Scale is graded using the Ora Calibra Ocular Discomfort Scale (ODS). The scale ranges from 0 means no discomfort to 4 means worst discomfort. Higher score indicates more discomfort. Area under the curve is presented. AUC at each visit is calculated as follows: Calculate (time point - previous time point)\*0.5\*(discomfort score at time point + previous discomfort score at time point) then sum all of those values together. Given that this was taken every 5 minutes from 0 to 90 minutes, the maximum value for AUC would then be (5\*0.5\*8)\*18=360, and the minimum value would be (5\*0.5\*0)\*18=0. Given this, the minimum and maximum change from baseline would be -360 to 360.

Time frame: Baseline, Visit 5 (Day 7), Visit 6 (Day 14), and Visit 7 (Day 28)

Population: Analysis was done on ITT population with Observed Data Only. The number analyzed in one or more rows differs from overall number analyzed because the number of participants/study eye analyzed can vary with each visit.
