Detailed Description

This was a Phase 2, multicenter, randomized, double-masked, placebo controlled study designed to evaluate the safety and efficacy of OC 02 Nasal Spray in adult participants with dry eye disease. Approximately 160 subjects, at least 22 years of age, with a subject-reported history of dry eye disease and meeting all other study eligibility criteria were planned to be randomized to receive an application of OC-02 or placebo at Visit 1 and Visit 2.

Description

Inclusion Criteria:

  • Have used and/or desired to use an artificial tear substitute for dry eye symptoms within 6 months prior to Visit 1

Exclusion Criteria:

  • Have had any intraocular surgery (such as cataract surgery), extraocular surgery (such as blepharoplasty) in either eye within three months or refractive surgery within twelve months of Visit 1
  • Have a history or presence of any ocular disorder or condition in either eye that would, in the opinion of the Investigator, likely interfere with the interpretation of the study results or participant safety such as significant corneal or conjunctival scarring; pterygium or nodular pinguecula; current ocular infection, conjunctivitis, or inflammation not associated with dry eye; anterior (epithelial) basement membrane corneal dystrophy or other clinically significant corneal dystrophy or degeneration; ocular herpetic infection; evidence of keratoconus; etc. Blepharitis not requiring treatment and mild meibomian gland disease that are typically associated with DED are allowed.
  • Have a systemic condition or disease not stabilized or judged by the Investigator to be incompatible with participation in the study or with the lengthier assessments required by the study (e.g., current systemic infection, uncontrolled autoimmune disease, uncontrolled immunodeficiency disease, history of myocardial infarction or heart disease, etc.)
  • Have a known hypersensitivity to any of the procedural agents or study drug components
  • Have any condition or history that, in the opinion of the investigator, may interfere with study compliance, outcome measures, safety parameters, and/or the general medical condition of the subject

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Schirmer's Test Score at Day 1
Time Frame: Day 1 (Pre to Post-Treatment Change)
The primary endpoint was the change in anesthetized Schirmer's Test Score (STS) from baseline to Day 1. Change in Schirmer test score pre to post treatment. The Schirmer's test measures the amount of tears produced by placing a paper strip in the eye for 5 minutes and distance of wetting was recorded. Schirmer's test scores from 0-35 mm where a higher score is indicative of a better outcome.
Day 1 (Pre to Post-Treatment Change)
Eye Dryness Score at Visit 2
Time Frame: Day 15 (Pre to Post-Treatment Change)
Change in Eye Dryness score from baseline to Day 15. Eye dryness score on a Visual Analogue Scale (VAS) from 0 (no discomfort) to 100 (maximum discomfort) millimeters where a lower score is indicative of a better outcome.
Day 15 (Pre to Post-Treatment Change)
