Study Endpoints

Primary Endpoints

Percentage of Participants With Ocular and Systemic (Non-ocular) Adverse Events (AEs)
Part 1: Baseline up to Week 24; Parts 2 & 3: Baseline up to Week 48
Percentage of Participants With Ocular AEs During the Post-operative and Follow-up Periods
Parts 2 and 3: From Day 1 to Week 4 and during follow-up period (up to Week 48)
Percentage of Participants With Adverse Events of Special Interest (AESIs) Including Ocular AESIs
Part 1: Baseline up to Week 24; Parts 2 and 3: Baseline up to Week 48
Percentage of Participants With Ocular AESIs During the Post-operative and Follow-up Periods
Parts 2 and 3: From Day 1 to Week 4 and during follow-up period (up to Week 48)
Duration of Ocular AESIs
Part 1: Baseline up to Week 24; Parts 2 and 3: Baseline up to Week 48
Duration of Ocular AESIs During the Post-operative and Follow-up Periods
Parts 2 and 3: From Day 1 to Week 4 and during follow-up period (up to Week 48)
Percentage of Participants With Adverse Device Effects (ADEs)
Parts 2 and 3: Baseline up to Week 48
Duration of ADEs
Parts 2 and 3: Baseline up to Week 48
Percentage of Participants With Anticipated Serious ADEs (ASADEs)
Parts 2 and 3: Baseline up to Week 48
Duration of ASADEs
Parts 2 and 3: Baseline up to Week 48
Change From Baseline in Early Treatment Diabetic Retinopathy Study - Best Corrected Visual Acuity (ETDRS-BCVA) Score at Week 48
Part 3: Baseline (baseline visit, before implant insertion), and Week 48

ETDRS-BCVA will be used to quantify visual acuity. BCVA is measured using an eye chart and is reported as the number of letters read correctly using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved.

Secondary Endpoints

Maximum Observed Concentration (Cmax) of Zifibancimig in Blood and Aqueous Humor (AH)
Part 1: Baseline up to Week 24; Parts 2 and 3: Baseline up to Week 144
Time of Maximum Concentration Observed (Tmax) of Zifibancimig in Blood and AH
Part 1: Baseline up to Week 24; Parts 2 and 3: Baseline up to Week 144
Concentration at the End of a Dosing Interval Before the Next Dose Administration (Ctrough) of Zifibancimig in Blood and AH
Part 1: Baseline up to Week 24; Parts 2 and 3: Baseline up to Week 144

Interventions

NameTypeDescription
ZifibancimigDRUGPart 1: multiple ascending doses by IVT injection. Each participant will receive zifibancimig at a constant volume of 50 microliter (µL) in the study eye. Part 2: participants will be randomized to one of two dose levels of zifibancimig in the PD implant. Part 3: Participants will receive one of the two dose levels of zifibancimig in the PD implant.
RanibizumabDRUGParticipants will receive ranibizumab 100 mg/mL through the PD implant
Port Delivery PlatformDEVICEParticipants will receive intraocular refillable device that is surgically inserted into the eye for continuous delivery of drugs into the vitreous.
