5 Key Takeaways
  • 1

    VIS-101, a bispecific inhibitor, improved visual acuity in patients with neovascular age-related macular degeneration (nAMD).

  • 2

    The therapy showed mean gains of over 10 letters on the ETDRS scale and reduced retinal thickness by 100-150 µm after three doses.

  • 3

    Approximately two-thirds of patients required no retreatment at 4 months, with about half remaining retreatment-free at 6 months.

  • 4

    The phase 2a study enrolled 38 patients aged 50 to 80 years, randomized to receive either 6 mg or 3 mg of VIS-101.

  • 5

    A phase 2b study is planned for 2026, with ongoing investigations of VIS-101 for diabetic macular edema and retinal vein occlusion.
