A Study to Evaluate the Long-Term Safety and Tolerability of Faricimab in Participants With Diabetic Macular Edema

This is a multicenter long-term extension study designed to evaluate the long-term safety and tolerability of faricimab administered by intravitreal (IVT) injection at a personalized treatment interval (PTI) to participants who enrolled in and completed one of the two Phase III studies, GR40349 (NCT03622580) or GR40398 (NCT03622593), also referred to as the parent studies.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Previous enrollment in and completion of Study GR40349 (NCT03622580) or GR40398 (NCT03622593), without study or study drug discontinuation
  • Ability to comply with the study protocol, in the investigator's judgment
  • For women of childbearing potential: agreement to remain abstinent or use acceptable contraceptive methods that result in a failure rate of <1% per year during the treatment period and for at least 3 months after the final dose of study treatment

Exclusion criteria

  • Pregnant or breastfeeding, or intending to become pregnant during the study or within 3 months after the final intravitreal injection of faricimab
  • Presence of other ocular diseases that give reasonable suspicion of a disease or condition that contraindicates the use of faricimab, that might affect interpretation of the results of the study or that renders the patient at high risk for treatment complications
  • Presence of other diseases, metabolic dysfunction, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of faricimab and that might affect interpretation of the results of the study or that renders the patient at high risk of treatment complications
  • History of a severe allergic reaction or anaphylactic reaction to a biologic agent or known hypersensitivity to any component of the faricimab injections, study treatment procedure, dilating drops, or any of the anesthetic and antimicrobial preparations used by a patient during the study
  • Requirement for continuous use of any medications or treatments indicated as prohibited therapy

Treatment and study plan

Faricimab

Drug

Faricimab will be administered by intravitreal (IVT) injection into the study eye according to the personalized treatment interval (PTI) dosing regimen.

Other names: RO6867461, RG7716

Sham Procedure

Other

The sham is a procedure that mimics an IVT injection and involves the blunt end of an empty syringe (without a needle) being pressed against the anesthetized eye. The sham procedure will be administered to participants as appropriate during the first 16 weeks of this study in order to maintain the masking of the initial faricimab PTI.

Primary outcomes

  1. Incidence and Severity of Ocular Adverse Events in the Study Eye, With Severity Determined According to Adverse Event Severity Grading Scale

    Time frame: From the day of the first dose of faricimab until the end of the study (up to 108 weeks)

    This is an analysis of participants with at least one ocular adverse event (AE) that occurred in the study eye. Investigators sought information on AEs at each contact with the participants. All AEs were recorded and the investigator made an assessment of the seriousness, severity (e.g., mild, moderate, or severe intensity), and causality for each AE. AEs of special interest (AESI) included the following: Sight-threatening AEs that cause a drop in visual acuity (VA) score ≥30 letters lasting more than 1 hour, are associated with severe intraocular inflammation (IOI), or require surgical or medical intervention to prevent permanent loss of sight; suspected transmission of an infectious agent by the study drug; and, cases of potential drug-induced liver injury that include an elevated ALT or AST in combination with either an elevated bilirubin or clinical jaundice, as defined by Hy's Law.

  2. Incidence of Ocular Adverse Events in the Fellow Eye

    Time frame: From the day of the first dose of faricimab until the end of the study (up to 108 weeks)

    This is an analysis of participants with at least one ocular adverse event (AE) that occurred in the fellow eye (i.e., non-study eye). Investigators sought information on AEs at each contact with the participants. All AEs were recorded and the investigator made an assessment of the seriousness, severity, and causality for each AE. AEs of special interest (AESI) included the following: Sight-threatening AEs that cause a drop in visual acuity (VA) score ≥30 letters lasting more than 1 hour, are associated with severe intraocular inflammation (IOI), or require surgical or medical intervention to prevent permanent loss of sight; suspected transmission of an infectious agent by the study drug; and, cases of potential drug-induced liver injury that include an elevated ALT or AST in combination with either an elevated bilirubin or clinical jaundice, as defined by Hy's Law.

  3. Incidence and Severity of Non-Ocular Adverse Events, With Severity Determined According to Adverse Event Severity Grading Scale

    Time frame: From the day of the first dose of faricimab until the end of the study (up to 108 weeks)

    This is an analysis of participants with at least one non-ocular (systemic) adverse event (AE). Investigators sought information on AEs at each contact with the participants. All AEs were recorded and the investigator made an assessment of the seriousness, severity (e.g., mild, moderate, or severe intensity), and causality for each AE. AEs of special interest (AESI) included the following: Sight-threatening AEs that cause a drop in visual acuity (VA) score ≥30 letters lasting more than 1 hour, are associated with severe intraocular inflammation (IOI), or require surgical or medical intervention to prevent permanent loss of sight; suspected transmission of an infectious agent by the study drug; and, cases of potential drug-induced liver injury that include an elevated ALT or AST in combination with either an elevated bilirubin or clinical jaundice, as defined by Hy's Law.
