A Study to Evaluate Efficacy, Safety, and Immunogenicity With ABP 938 8 mg Versus EYLEA® HD (Aflibercept) in Participants With Neovascular Age-related Macular Degeneration

22. maj 2026 opdateret af: Amgen

A Randomized, Double-masked, Comparative Clinical Study Evaluating the Efficacy, Safety, and Immunogenicity of ABP 938 8 mg Versus EYLEA® HD (Aflibercept) Delivered Via Intravitreal Injection in Participants With Neovascular Age-related Macular Degeneration

The aim of this trial is to demonstrate similarity in efficacy between ABP 938 8 mg and aflibercept (US) 8 mg by evaluating the change in best corrected visual acuity (BCVA) in participants with neovascular age-related macular degeneration (nAMD)

Beskrivelse

Inclusion Criteria:

  • Men or women ≥ 50 years old, capable of giving signed informed consent
  • Active, treatment-naïve subfoveal CNV lesions secondary to nAMD including juxtafoveal lesions that affect the fovea as confirmed by SD-OCT and FA in the study eye (SE)
  • Total area of CNV (including both classic and occult components) > 50% of the total lesion area in the SE
  • The BCVA letter score ≥ 24 and ≤ 78 letters, in the SE
  • Presence of intra and/or subretinal fluid affecting the central subfield of the SE as identified by SD-OCT attributable to active CNV. The central subfield is defined as a circle with a diameter of 1 mm, centered on the fovea

Exclusion Criteria:

Participants are excluded from the study if any of the following criteria apply at either screening or baseline, unless otherwise indicated per protocol:

  • Total lesion size > 12 disc areas (30.5 mm2) including blood, scars, and neovascularization, in the study eye
  • Scar, fibrosis, or atrophy involving the central subfield in the study eye
  • Scar or fibrosis involving > 50% of the total lesion in the study eye
  • Presence of retinal pigment epithelium tears or rips involving the macula in the study eye
  • History of any vitreous hemorrhage ≤ 4 weeks (28 days) before randomization in the study
  • Presence of other causes of CNV, including pathologic myopia (spherical equivalent ≥ 8 diopters negative or axial length ≥ 25 mm), ocular histoplasmosis syndrome, angioid streaks, choroidal rupture, or multifocal choroiditis in the study
  • Uncontrolled glaucoma (defined as IOP >25 mmHg despite treatment with anti-glaucoma medication) in the study eye
  • History or clinical evidence of DR, DME, idiopathic autoimmune uveitis, or any other vascular disease affecting the retina, other than nAMD in either eye
  • Evidence of active extraocular or periocular infection or inflammation (including infectious blepharitis, keratitis, scleritis, or conjunctivitis) in either eye at the time of screening or randomization
  • Uncontrolled blood pressure (defined as systolic >160 mmHg or diastolic >95 mmHg). Blood pressure needs to be stable for at least 12 weeks (84 days) prior to screening
  • Any prior or concomitant ocular or systemic treatment (with an investigational or approved, anti VEGF or anti-VEGF/anti-angiopoietin agent) in the SE, or surgery for nAMD in the SE, except dietary supplements or vitamins
  • History or evidence of any other clinically significant disorder, condition, disease or clinical laboratory abnormality that, in the opinion of the investigator or study medical monitor, if consulted, would pose a risk to participant safety or interfere with the study evaluation or results interpretation
  • Other protocol-specified exclusion criteria

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: ABP 938 8 mg
Participants 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.
IVT injection
Aktiv komparator: Aflibercept (US) 8 mg
Participants 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.

IPD-planbeskrivelse

De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.

IPD-delingstidsramme

Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

IPD-delingsadgangskriterier

Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
