Official Title  ICMJE A Phase 3 Double-masked, Randomized, Multicenter Study of the Efficacy and Safety of OCS 01 Eye Drops in Subjects With Diabetic Macular Edema
Brief Summary The primary objective is to evaluate the efficacy and safety of OCS 01 as compared to Vehicle in subjects with Diabetic Macular Edema (DME).
Detailed Description A Phase 3 Double-masked, Randomized, Multicenter Study of the Efficacy and Safety of OCS 01 Eye Drops in Subjects with Diabetic Macular Edema
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Condition  ICMJE Diabetic Macular Edema
Intervention  ICMJE
  • Drug: Dexamethasone ophthalmic suspension (OCS-01)

    The interventional drug OCS-01 eye drops will be dispensed in single dose containers for each subject to have enough medication until the next visit.

    Subjects will be dosed with eye drop of OCS-01 6 times per day for 6 weeks (induction phase) followed by 3 times per day for 46 weeks (maintenance phase).

    Other Name: Dexamethasone
  • Drug: Vehicle

    The vehicle drug (placebo) eye drops will be dispensed in single dose containers for each subject to have enough medication until the next visit.

    Subjects will be dosed with eye drop of vehicle 6 times per day for 6 weeks (induction phase) followed by 3 times per day for 46 weeks (maintenance phase).

    Other Name: Placebo
Study Arms  ICMJE

Eligibility Criteria  ICMJE

Inclusion Criteria (selection):

  1. Have a signed informed consent form before any study-specific procedures are performed.
  2. Have DME with presence of intraretinal and/or subretinal fluid in the study eye, with CST of ≥310 µm by SD-OCT at screening (Visit 1) (as assessed by an independent reading center).
  3. Have a documented diagnosis of Type 1 or Type 2 diabetes mellitus and an HbA1c of ≤ 10.0% prior to screening (Visit 1).

Exclusion Criteria (selection):

  1. Have macular edema considered to be because of a cause other than DME.
  2. Have a decrease in BCVA because of causes other than DME.
  3. Have a known history of significant macular ischemia which would prevent gain in visual acuity in the study eye.
