Summary:

      This is an exploratory, prospective, multicenter, open-label, single-arm, interventional,
      Phase IIb study designed to explore the associations over time between clinical assessments,
      multimodal imaging assessments, aqueous humor (AH) biomarker patterns, and genetic

      faricimab.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Diagnosis of diabetes mellitus (Type 1 or Type 2), as defined by the World Health
             Organization (WHO) and/or American Diabetes Association

          -  Hemoglobin A1c (HbA1c) ≤10%

          -  Patients who are intravitreal (IVT) treatment-naïve in the study eye

          -  Diabetic macular edema (DME) defined as macular thickening by spectral-domain optical
             coherence tomography (SD-OCT) involving the center of the macula. This inclusion
             criterion is to be assessed by the central reading center (CRC).

          -  Decreased visual acuity (VA) attributable primarily to DME

          -  Clear ocular media and adequate pupillary dilation to allow acquisition of good
             quality retinal images to confirm diagnosis

        Exclusion Criteria:

          -  Currently untreated diabetes mellitus or previously untreated patients who initiated
             oral or injectable anti-diabetic medication within 3 months prior to Day 1

          -  Any known hypersensitivity to any of the components in the faricimab injection,
             dilating eye drops, or any of the anesthetics and antimicrobial preparations used by
             the patient during the study

             examination finding, historical or current clinical laboratory finding giving
             reasonable suspicion of a condition that contraindicates the use of the faricimab or
             that might affect interpretation of the results of the study or renders the patient at
             high-risk for treatment complications, in the opinion of the Investigator

             is permitted

             aqueous humor (AH) inflammatory biomarkers.

          -  Patients who are currently enrolled in or have participated in any other clinical
             study involving an investigational product or device, or in any other type of medical
