Inclusion Criteria

•Age ???18 years
Type of DME Patients and Disease Characteristics
•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 IVT treatment-naïve in the study eye
Ocular Inclusion Criteria for Study Eye
•Diabetic macular edema (DME) defined as macular thickening by spectral-domain optical coherence tomography (SD-OCT) involving the center of the macula: CST of =325 µm with Spectralis® at screening. This inclusion criterion is to be assessed by the central reading center (CRC)
•Decreased VA attributable primarily to DME, with BCVA letter score of 75 to 20 letters (both inclusive) on ETDRS-like charts at the screening visit
•Clear ocular media and adequate pupillary dilation to allow acquisition of good quality retinal images to confirm diagnosis
Contraception
•For women of childbearing potential: agreement to remain abstinent or use contraception, must remain abstinent or use contraceptive methods with a failure rate of <1% per year during the treatment period and for at least 3 months after the final dose of faricimab

Exclusion Criteria

Medical Conditions
•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
•Any major illness or major surgical procedure within 1 month before the Day 1. One re-screening for this criterion is permitted
•History of other diseases, other non-diabetic metabolic dysfunction, physical 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
•Active cancer within the past 12 months prior to Day 1 except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, and prostate cancer with a Gleason score of =6 and a stable prostate-specific antigen for >12 months
•Stroke or myocardial infarction within 12 months prior to the Day 1. One re-screening for this criterion is permitted
•Any febrile illness within 1 week prior to Day 1. One re-screening for this criterion is permitted
•Pregnant or breastfeeding, or intending to become pregnant during the study or within 3 months after the final dose of faricimab
•WOCBP must have a negative serum pregnancy test result within 28 days prior to initiation of faricimab and a negative urine pregnancy test at the baseline visit
•Renal failure requiring renal transplant, hemodialysis, or peritoneal dialysis within 6 months prior to Day 1 or anticipated to require hemodialysis or peritoneal dialysis at any time during the study
•Any condition resulting in a compromised immune system that is likely to impact the 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 research, within 3 months or 5 half-lives prior to Day 1 and up to completion of the current study
•Substance abuse occurring within 12 months prior to screening, in the Investigator's judgment
•Use of systemic immunomodulatory treatments within 6 months or 5 half-lives prior to Day 1, systemic corticosteroids within 1 month prior to Day 1
•Any prior or concomitant systemic anti-VEGF treatment within 6 months or 5 half-lives prior to Day 1
•Use of systemic medications known to be toxic to the lens, retina or optic nerve used during the 6-month period or 5 half-lives prior to Day 1 or likely need to be used
•Received a blood transfusion within 3 months prior to the screening visit, received any treatment that leads to immunosuppression within 6 months or 5 half-lives prior to Day 1
Ocular Exclusion Criteria for Study Eye
•High-risk PDR defined as ETDRS DRSS. This exclusion criterion is to be assessed by the CRC
•Any history of or ongoing rubeosis iridis
•Any panretinal photocoagulation or macular laser photocoagulation treatment received in the study eye prior to the screening visit or expected to be received between the screening visit and Day 1
•Any history of treatment with anti-VEGF or any periocular or IVT corticosteroids in the study eye and no such treatment planned for the time between screening
