Brief Summary:
SDP-4-CS202 is a Phase 2, multicenter, double-masked, randomized, vehicle-controlled, parallel group study designed to evaluate the ocular efficacy of SDP-4 ophthalmic solution in subjects with moderate to severe dry eye disease over an 8-week treatment period. Once concentration (1%) of SDP-4 ophthalmic solution will be given in a parallel group to vehicle via topical ocular instillation BID.

Primary Outcome Measures :
  1. Symptom Assessment in Dry Eye (SANDE) Questionnaire [ Time Frame: 56 days ]
    Mean change from baseline in total SANDE at Visit 5/Day 56


Secondary Outcome Measures :
  1. Corneal fluorescein staining [ Time Frame: 56 days ]
    Mean and mean change from baseline at each visit

  2. Tear Breakup Time [ Time Frame: 56 days ]
    Mean and mean change from baseline at each visit

  3. Conjunctival hyperemia [ Time Frame: 56 days ]
    Mean and mean change from baseline at each visit

  4. Individual symptom Visual Analog Scale (VAS) scores, separately for each symptom [ Time Frame: 56 days ]
    Mean and mean change from baseline at each visit as measured on a scale from 0 to 100, where higher scores indicate a worse outcome

Criteria

Inclusion Criteria:

  • Have DED in both eyes, as supported by a subject-reported history of daily symptoms of dryeye for ≥ 6 months prior to Visit 1/Screening requiring the use of artificial tears.
  • Total score ≥ 40 and ≤ 70 on the SANDE questionnaire at Visits 1 and 2.
  • Tear break-up time (TBUT) of ≤ 6 seconds in both eyes at Visits 1 and 2.
  • Anesthetized Schirmer's test tear volume ≥ 3 mm and <10 mm in both eyes (only at Visit 1).
  • Best-corrected visual acuity (BCVA) of +0.7 logMAR or better in each eye as assessed by logMAR chart at Visits 1 and 2.

Exclusion Criteria:

  • Ocular surface corneal disease other than DED.
  • Diagnosis of Sjögren's disease.
  • Lid margin disorder other than meibomian gland dysfunction (MGD)
  • Presence of any ocular condition (e.g., pterygium) that in the Investigator's opinion could affect study parameters.
  • Any previous reconstructive or cosmetic eyelid surgery
  • Any previous invasive glaucoma and/or corneal surgery
  • Corneal refractive surgery in the 12 months prior to Visit 1/Screening.
  • Cataract extraction within 90 days prior to Visit 1/Screening.
  • Cauterization of the punctum or punctal plug (silicone or collagen) insertion or removal within 30 days prior to Visit 1/Screening or planned during the study.
  • Contact lens wear.
  • Use of ophthlamic corticosteroids, NSAIDs, antibiotics, antihistamines, IOP lowering medication, in the 30 days prior to Visit 1/Screening
  • Serious systemic disease or uncontrolled medical condition that in the judgment of the Investigator could confound study assessments
