NCT04514653

Brief Summary

This interventional study is being conducted with an investigational gene therapy treatment called ABBV-RGX-314 (also known as RGX-314) and is being developed as a potential one-time gene therapy treatment for neovascular (wet) age-related macular degeneration (wet AMD or nAMD). The typical treatment for nAMD is frequent injections of anti-VEGF therapy. Researchers are testing ABBV-RGX-314 to see if it has similar effects as the current approved standard of care, such as Lucentis® or Eylea® injections. The duration of this study will be up to 52 weeks or for ranibizumab control participants who cross over to ABBV-RGX-314 after week 52, up to 80 weeks post-randomization. The primary outcome measure for this investigational study is to evaluate the mean change in best-corrected visual acuity (BCVA) for ABBV-RGX-314 compared with ranibizumab monthly at the Week 40 visit.

Outcome Measures

Primary Outcomes (1)

  • Mean change from baseline in BCVA to Week 40 based on the Early Treatment Diabetic Retinopathy Study (ETDRS) score

    The scale used is the early treatment diabetic retinopathy study (ETDRS) letter score from 0-100 and higher score being better vision.

    40 weeks

Secondary Outcomes (14)

  • Incidence of overall and ocular adverse events (AEs) and serious adverse events (SAEs)

    52 weeks

  • Vector shedding analysis in serum, urine, and tears

    52 Weeks

  • Proportion of participants who experience ocular inflammation following SCS ABBV-RGX-314 administration

    52 weeks

  • Mean change from baseline in choroidal neovascularization (CNV) lesion size and leakage area based on fluorescein angiography (FA)

    Up to Week 80

  • Mean change from baseline in BCVA based on ETDRS score

    Up to Week 80

  • +9 more secondary outcomes

Masking Details
The vision examiners and central reading center (CRC) graders will be masked, meaning they will be unaware of the participants' treatment assignment. All other individuals affiliated with the study (investigators, all study center personnel apart from the vision examiners, the participants, all staff of Sponsor and its research collaborator, all staff affiliated with the contract research organization, and all CRC staff apart from the CRC graders) will have knowledge of the treatment assignment.
