Study Arms (4)

Arm A: 0.25 mg Vamikibart Q8W

EXPERIMENTAL

Participants will receive vamikibart 0.25 milligrams (mg), by intravitreal (IVT) injection, on Day 1 and every 8th week (Q8W), up to Week 44, for a total of 6 injections. A sham procedure will be administered during study visits at which no study drug is administered to maintain masking between treatment arms.

Drug: VamikibartOther: Sham Procedure

Arm B: 1.0 mg Vamikibart Q8W

EXPERIMENTAL

Participants will receive vamikibart 1.0 mg, by IVT injection, on Day 1 and Q8W, up to Week 44, for a total of 6 injections. A sham procedure will be administered during study visits at which no study drug is administered to maintain masking between treatment arms.

Drug: VamikibartOther: Sham Procedure

Arm C: 1.0 mg Vamikibart Q4W

EXPERIMENTAL

Participants will receive vamikibart 1.0 mg, by IVT injection, on Day 1 and every 4th week (Q4W), up to Week 44 for a total of 12 injections.

Drug: Vamikibart

Arm D: 0.5 mg Ranibizumab Q4W

ACTIVE COMPARATOR

Participants will receive ranibizumab 0.5 mg, by IVT injection, on Day 1 and Q4W, up to Week 44 for a total of 12 injections.

Drug: Ranibizumab

Interventions

Vamikibart will be administered by IVT injection as specified in each treatment arm.

Also known as: RO7200220
Arm A: 0.25 mg Vamikibart Q8WArm B: 1.0 mg Vamikibart Q8WArm C: 1.0 mg Vamikibart Q4W

Ranibizumab 0.5 mg will be administered to the participants by IVT injection, as specified in the treatment arm.

Also known as: Lucentis
Arm D: 0.5 mg Ranibizumab Q4W

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. Sham procedure will be administered to participants in the Q8W arms at applicable visits to maintain masking between treatment arms.

Arm A: 0.25 mg Vamikibart Q8WArm B: 1.0 mg Vamikibart Q8W

  • Ability and willingness to provide written informed consent and to comply with the study protocol
  • Willingness to allow Aqueous Humor collection
  • For women of childbearing potential: agreement to remain abstinent or use at least one highly effective contraceptive method that results in a failure rate of \<1% per year during the treatment period and for at least 12 weeks after the final dose of study treatment

You may not qualify if:

  • Hemoglobin A1c (HbA1c) of greater than (\>) 12%
  • Uncontrolled blood pressure, defined as a systolic value greater than (\>)180 millimeters of mercury (mmHg) and/or a diastolic value \>100 mmHg while a patient is at rest
  • Currently pregnant or breastfeeding, or intend to become pregnant during the study
  • Prior treatment with panretinal photocoagulation or macular laser to the study eye
  • Any intraocular or periocular corticosteroid treatment within the past 16 weeks prior to Day 1 to the study eye
  • Prior Iluvien or Retisert implants within 3 years prior to Day 1 to the study eye
  • Prior or concomitant treatment with anti-VEGF therapy within 8 weeks prior to Day 1 to the study eye; Vabysmo\^TM within 16 weeks prior to Day 1, prior Beovu® is not permitted
  • Prior administration of IVT brolucizumab (Beovu®): ever; vamikibart: \</=24 weeks prior to Day 1) in either eye
  • Any proliferative diabetic retinopathy
  • Active intraocular or periocular infection or active intraocular inflammation in the study eye
  • Any current or history of ocular disease other than DME that may confound assessment of the macula or affect central vision in the study eye
  • Any current ocular condition which, in the opinion of the investigator, is currently causing or could be expected to contribute to irreversible vision loss due to a cause other than DME in the study eye
