Diabetic Macular Edema
Conditions
Brief summary
This study is designed to investigate treatment response in treatment-naïve underrepresented patients with diabetic macular edema (DME) who are treated with faricimab. The study population will consist of participants ≥18 years of age who self-identify as Black/African American, Hispanic/Latino American, or Native American/Alaska Native/Native Hawaiian or other Pacific Islander; in addition, a cohort of Asian Indian participants will be enrolled in India.
Interventions
Participants will receive 6-milligram (mg) faricimab intravitreal (IVT) injections, as described in the study arm descriptions for each study phase.

Intervention model description
This is a multicenter, open-label, single-arm study with two phases: the main study phase for all eligible patients (up to 56 weeks), followed by an optional long-term extension phase for eligible patients only in the U.S. (up to 100 weeks).
Eligibility
Inclusion criteria
Main Phase General Inclusion Criteria: * Self-identify as Black/African American, Hispanic/Latino American, or Native American/Alaska Native/Native Hawaiian or other Pacific Islander; or self-identify as Asian Indian residents of the Indian subcontinent * Diagnosis of diabetes mellitus (type 1 or type 2), as defined by the World Health Organization (WHO) and/or American Diabetes Association, and current regular use of insulin or other injectable drugs (e.g., dulaglutide and liraglutide) and/or oral anti-hyperglycemic agents for the treatment of diabetes * Hemoglobin A1c (HbA1c) ≤10% (Note: up to 20% of participants enrolled may have HbA1c up to 12%) * For women of childbearing potential: Agreement to remain abstinent (refrain from heterosexual intercourse) or use acceptable contraception methods as defined in the protocol Main Phase Ocular Inclusion Criteria for Study Eye: * Intravitreal (IVT) treatment-naïve in the study eye (i.e., have not received previous treatment with any anti-VEGF IVT or any corticosteroids periocular or IVT in the study eye) * Diabetic macular edema, defined as macular thickening by SD-OCT involving the center of the macula * BCVA letter score of 73 to 20 letters (both inclusive) using the ETDRS protocol at the initial testing distance of 4 meters at the baseline visit (Day 1) * Clear ocular media and adequate pupillary dilation to allow acquisition of good quality retinal images to confirm diagnosis Long-Term Extension (LTE) Inclusion Criteria: * Enrollment in and completion of the main study, without discontinuation from study or study drug treatment * Signed LTE-phase Informed Consent Form * Ability to comply with the study protocol, in the investigator's judgment * For women of childbearing potential: Agreement to remain abstinent (refrain from heterosexual intercourse) or use acceptable contraception methods as defined in the protocol
