A Study to Assess the Safety and Efficacy of IC265 Ophthalmic Solution for Dry Eye in Adult Participants

A Phase 2, Single-Center, Randomized, Double- Masked, Placebo-Controlled Study to Assess the Safety and Efficacy of IC265 Ophthalmic Solution 1% in Subjects Diagnosed With Dry Eye Disease

This study will evaluate the safety, tolerability and efficacy of IC265 compared to vehicle in participants with signs and symptoms dry eye disease.

• Report a score of ≥ 2 on a Ocular Discomfort & 4-symptom questionnaire in at least one symptom at Visits 1 and 2

• Have a Schirmer's Test score of ≤10mm and ≥1mm in at least one eye at Visits 1and 2

• Have a pre-CAE(controlled adverse environment) (conjunctival redness score ≥ 1 according to the Conjunctival Redness for Dry Eye Scale in at least one eye at Visits 1 and 2

• Have a corneal fluorescein staining score of ≥ 2 in at least one region (e.g. inferior, superior, or central) at Visits 1 and 2

• Have a sum corneal fluorescein staining score of ≥ 4, based on the sum of the inferior, superior, and central regions at Visits 1 and 2

• Have a total lissamine green conjunctival score of ≥ 2, based on the sum of the temporal and nasal regions at Visits 1 and 2

• Demonstrate a response to the CAE at Visits 1 and 2 as defined by:

  1. Having at least a ≥1 point increase in fluorescein staining in the inferior region in at least one eye following CAE exposure
  2. Reporting an Ocular Discomfort Score ≥3 at 2 or more consecutive time points in at least one eye during CAE exposure (if a subject has an ocular discomfort rating of 3 at time = 0 for an eye, s/he must report an ocular discomfort rating of 4 for two consecutive measurements for that eye) Note: a subject cannot have an ocular discomfort score of 4 at time = 0)

Exclusion Criteria:

• Have any clinically significant slit lamp findings at Visit 1 that may include active blepharitis, meibomian gland dysfunction, ocular rosacea, lid margin inflammation or active ocular allergies that require therapeutic treatment
