About this trial
This clinical study is aimed at evaluating the safety and effectiveness of 2 test formulations (Rain and Mist), against an approved over-the-counter formulation (Systane Ultra) and a placebo (saline), in the treatment of moderate dry eye disease.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Be at least 18 years of age at the Screening Visit;
Of either gender and any race;
Be willing and able to follow all instructions and attend all study visits;
A corneal fluorescein staining score of ≥ 2 in at least one corneal region OR have a sum of ≥ 4 in all corneal regions
Disqualifiers
Have a known hypersensitivity to any of the procedural agents or study drug components, or have previously used the study drug;
Have clinically significant corneal epithelial defects at Visit 1, prior to performing Schirmer's Test;
Have had any intraocular surgery (such as cataract surgery) or extraocular surgery in either eye within three months, or refractive surgery (e.g., laser-assisted in-situ keratomileusis, laser epithelial keratomileusis, photorefractive keratectomy or corneal implant) within twelve months of Visit 1;
Have had blepharoplasty in either eye;

Treatments tested in this trial
Two test formulations for the treatment of DED are being compared against the approved OTC formulation (Systane Ultra) and saline (placebo).
DrugRain and Mist are the test formulations. Systane Ultra is an approved OTC formulation. Saline is the placebo.
Treatment groups
Trial outcomes
Primary outcomes
Schirmer's Test
Mean change in Schirmer's Test Score (STS) from pre-instillation of IP to 5 minutes post-instillation of IP at Visits 1 and 2
Tear Film Break Up Time (TFBUT)
Mean change in Tear Film Break Up Time (TFBUT) from baseline to post- instillation of IP at each of Visits 1 and 2
Corneal Fluorescein Staining
Mean change from Baseline in Corneal Fluorescein Staining at Visits 1 and 2
Conjunctival Staining
Mean change from Baseline in Conjunctival Staining at Visits 1 and 2
Secondary outcomes
Secondary Efficacy Parameters
Measurement of inflammatory markers using ELISA: Changes in the levels of specific inflammatory markers will be evaluated using Enzyme-Linked Immunosorbent Assay (ELISA) at specified timepoints (Visit 1 and 2) to assess the anti-inflammatory efficacy of the PST Tear formulations.

Other outcomes
Tolerability Measures
Drop comfort assessment (0-10 unit scale) assessed by subject immediately upon instillation, at 1 minute, 3 minutes, and 5 minutes post-instillation at Visit 1 and Visit 2.
