Study Endpoints

Primary Endpoints

Change From Baseline in BCVA as measured by Early Treatment Diabetic Retinopathy Study (ETDRS) letter score
Baseline and Week 12
Percentage of IVT Injections Successfully Administered
Day of IVT injection (study day 1)

A successful injection was defined by whether the retinal specialist administering the IVT injection answered 'yes' to the following question: Did the PFS allow for the safe and effective administration of the prescribed dose? Percentage of successful injections and Clopper-Pearson 95% Confidence Interval is reported.

Mean Change From Baseline in BCVA at Week 8
Baseline and Week 8

BCVA score was assessed based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart by the study eye at 4 meters. ETDRS letters score could range from 0 to 100 letters at each assessment. A positive change from Baseline in ETDRS letter score indicated an improvement in visual acuity in the study eye. Change from Baseline calculated as observed post-baseline value - Baseline value.

Secondary Endpoints

Percentage of Participants With Absence of Intraretinal Fluid (IRF) and Subretinal Fluid (SRF) in the Center Subfield, as Assessed by Spectral-Domain Optical Coherence Tomography (SD-OCT)

ArmTypeDescription
ABP 938 8 mgEXPERIMENTALParticipants will receive intravitreal ABP 938 8 mg injections at Baseline, Week 4, and Week 8. Participants will then be assessed at scheduled study visits, with Dose Regimen Adjustment (DRA) decisions beginning at Week 16 based on predefined disease-activity criteria. Injections will be administered at protocol-defined intervals ranging from every 4 to 16 weeks through the end of the study.
Aflibercept (US) 8 mgACTIVE_COMPARATORParticipants will receive intravitreal Aflibercept (US) 8 mg injections at Baseline, Week 4, and Week 8. Participants will then be assessed at scheduled study visits, with DRA decisions beginning at Week 16 based on predefined disease-activity criteria. Injections will be administered at protocol-defined intervals ranging from every 4 to 16 weeks through the end of the study.
ABP 938EXPERIMENTALParticipants will be randomized in a ratio of 2:1 to receive either a single IVT injection of ABP 938 in a PFS or a single injection of aflibercept in a PFS.
AfliberceptEXPERIMENTALParticipants will be randomized in a ratio of 2:1 to receive either a single IVT injection of ABP 938 in a PFS or a single injection of aflibercept in a PFS.
ABP 938-Treatment Group AEXPERIMENTALSubjects will receive 2 mg (0.05 mL) of ABP 938 by intravitreal (IVT) injection every 4 weeks for the first 3 doses (ie, baseline/day 1, week 4, and week 8) and every 8 weeks from week 16 until week 48.
Aflibercept-Treatment Group B1ACTIVE_COMPARATORSubjects will receive 2 mg (0.05 mL) of aflibercept (Treatment Group B) by IVT injection every 4 weeks for the first 3 doses (ie, baseline/day 1, week 4, and week 8). Subjects will be re-randomized to receive aflibercept by IVT injection every 8 weeks from week 16 until week 48.

Frequently asked questions about ABP 938

What is ABP 938?

ABP 938 is an investigational small molecule in Phase 3 development by Amgen Inc. (ticker AMGN) for ophthalmology indications. It is being studied in chorioretinal vascular disease and neovascular (wet) age-related macular degeneration. It is not yet approved and remains in clinical development.

What is ABP 938 used for in neovascular age-related macular degeneration?

ABP 938 is being evaluated for the treatment of neovascular (wet) age-related macular degeneration, or nAMD, a form of chorioretinal vascular disease. Phase 3 studies compare ABP 938 8 mg with EYLEA HD (aflibercept) in participants with nAMD. It is investigational and not approved for this use.

Who makes ABP 938?
