Outcome Measures

Primary Outcomes (1)

  • Total Ocular Surface Disease Index

    The OSDI is a 12-item questionnaire designed to provide a rapid assessment of the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning. It is a scale of 0-4 for each of the 12 questions. A minimum value would be "0" and a maximum value would be "48". The higher the value the worse the outcome.

    Day 29

Secondary Outcomes (12)

  • Lissamine Green Staining

    Day 29

  • Tear Film Break-up Time

    Day 29

  • Conjunctival Redness

    Day 29

  • Schirmer's Test

    Day 29

  • Cochet-Bonnet Corneal Sensitivity Test

    Day 29

  • +7 more secondary outcomes

Other Outcomes (4)

  • Number of Participants With Treatment-related Adverse Events

    Adverse events will be collected from first dose of study drug to 30 days after treatment discontinuation (Day 29 + 4 weeks).

  • Slit-lamp Biomicroscopy

    Day 29

  • Intraocular Pressure

  • Have a diagnosis of type 1 or type 2 diabetes mellitus prior to Visit 1;
  • Have a reported history of dry eye for at least 6 months prior to Visit 1;
  • Have a history of use or desire to use eye drops for dry eye symptoms within 6 months of Visit 1;
  • Have a corneal fluorescein staining score of ≥ 2 in any region (inferior, superior, or central regions) in at least one eye at Visits 1 and 2 (must be the same eye at Visits 1 and 2);
  • Have at least one of the following at Visits 1 and 2:
  • A total lissamine green conjunctival score of ≥ 2 in at least one eye, based on the sum of the temporal and nasal regions at Visits 1 and 2 (must be the same eye at Visits 1 and 2);
  • Report an OSDI score ≥ 20 at Visits 1 and 2.

You may not qualify if:

  • Have any clinically significant slit lamp findings at Visit 1 that may include active blepharitis, meibomian gland dysfunction (MGD), lid margin inflammation or active ocular allergies that require therapeutic treatment, and/or in the opinion of the investigator may interfere with study parameters;
  • Be diagnosed with an ongoing ocular infection (bacterial, viral, or fungal), or active ocular inflammation at Visit 1;
  • Have concurrent neurotrophic keratopathy from a source other than diabetes (h/o HSV keratitis, h/o HZO with ocular manifestations, or CN VII palsy or other condition resulting in lagophthalmos);
  • Have active diabetic foot ulcers;
  • Have a corneal sensitivity score ≤ 1.5 cm as measured by Cochet-Bonnet at Visit 1;
  • Report an OSDI score \> 75 at Visits 1 and 2;
  • Have worn contact lenses within 21 days of Visit 1 or anticipate using contact lenses during the study (no contact lens wear during study);
  • Have used any eye drops within 2 hours of Visit 1;
  • Have previously had laser-assisted in situ keratomileusis (LASIK) surgery within the last 24 months;
  • Have used cyclosporine 0.05% or lifitigrast 5.0% ophthalmic solution within 45 days of Visit 1;
  • Have any planned ocular and/or lid surgeries over the study period or any ocular surgery within the last 12 months;
  • Be using or anticipate using temporary punctal plugs during the study that have not been stable within 30 days of Visit 1;
  • Be currently taking any topical ophthalmic prescription (including medications for glaucoma) or over-the-counter (OTC) solutions, artificial tears, gels or scrubs, and cannot discontinue these medications for the duration of the trial (excluding medications allowed for the conduct of the study);
  • Have corrected visual acuity greater than or equal to logMAR +0.7 as assessed by Early Treatment of Diabetic Retinopathy Study (ETDRS) scale in either eye at Visit 1;
  • Have concurrent autoimmune disease causing dry eye (e.g., rheumatoid arthritis, Sjogren's, GVHD, Steven's Johnson, Grave's);
  • +11 more criteria
