Eligibility Criteria
You may qualify if:
- \. Participant-reported history of DED in O.U. 5. History of non-prescription (over-the-counter) artificial tear product use within 30 days prior to start of the Screening.
You may not qualify if:
- \. Have a Current-corrected Visual Acuity (CCVA), using corrective lenses (spectacles) if necessary, in O.U. of + 0.7 or better as assessed by Early Treatment of Diabetic Retinopathy Study (ETDRS) chart.
- \. Have moderate to severe DED in at least one eye, as defined by meeting ALL the following criteria in the same eye:
- Unanesthetized STT score of \> 1 and ≤ 7 mm over five minutes.
- Total corneal fluorescein staining score of ≥ 4 \[0 to 15 National Eye Institute scale\] 10. Have symptom severity score of ≥ 60 for Eye Discomfort on the Individual Symptom Severity Assessment VAS (0 to 100) at Screening and a Symptom Severity Score of ≥ 50 for Eye Discomfort on the Individual Symptom Severity Assessment VAS (0 to 100) at Randomization (Day 1).
- Has a known hypersensitivity or contraindication to the study drug(s) or their components.
- In the opinion of the Investigator, be unwilling or unable to comply with the study protocol or unable to successfully self-administer eye drops.
- Use of any IP or device within 30 days prior to start of the Screening or during the study period.
- Any ocular condition that, in the opinion of the Investigator, could affect study parameters including, but not limited to, eyelid margin disorders (e.g., significant blepharitis including staphylococcal, demodex or seborrheic; severe meibomian gland disease, excessive lid laxity, floppy eyelid syndrome, ectropion or entropion), advanced conjuctivochalasis, Salzmann's nodular degeneration, iritis, uveitis, and/or active ocular infection.
- Participants with DED secondary to scarring (such as that seen with irradiation, alkali burns, Steven-Johnson syndrome, cicatricial pemphigoid) or destruction of conjunctival goblet cells (as with Vitamin A deficiency) are not eligible for the study. Participants with incidental scars secondary to refractive surgery (i.e., LASIK surgery) that, in the opinion of the Investigator, will not interfere with study compliance and/or outcome measures are not excluded from the study.
- Known history of alcohol and/or drug abuse within the past 12 months, that in the opinion of the Investigator, may interfere with study compliance, outcome measures including safety parameters, and/or general medical condition of the participant.
- History of active herpes simplex or zoster keratitis in either eye.
- History of neurotrophic keratitis or suspected history of neurotrophic keratitis in the clinical judgement of the Investigator (e.g., abnormal Cochet-Bonnet test).
- Intraocular pressure (IOP) \> 22 mmHg at the Screening Visit.
- Use of below listed medications and/or procedures within the appropriate pre-study period and throughout the study:
- a. Prohibited during the Screening Visit and throughout the study: i. Artificial tear substitutes ii. Current use of eye drops for glaucoma b. Prohibited 7 days prior to the Screening Visit and throughout the study: i. Contact Lenses c. Prohibited 14 days prior to the Screening Visit and throughout the study: i. Topical ocular or systemic antibiotics ii. Serum tears iii. Topical ocular non-steroidal anti-inflammatory drugs (NSAIDS) iv. Topical ocular or oral antihistamines or mast cell stabilizers v. Topical ocular or nasal vasoconstrictors. Phenylephrine to dilate is allowed.
