Brief Summary:
This is a multicenter, active-controlled, double masked study assessing the safety, efficacy and durability of four monthly intravitreal (IVT) injections of RBM-007 monotherapy, and four monthly RBM-007 injections in combination with Eylea® dosed at every other month, compared to Eylea® monotherapy dosed at every other month in approximately eighty-one subjects with exudative age-related macular degeneration (AMD).

Condition or disease Intervention/treatment Phase
Exudative Age-related Macular Degeneration Drug: RBM-007 Injectable Solution Drug: Aflibercept Drug: Sham Phase 2

Detailed Description:
RBM-007 is a novel oligonucleotide-based aptamer having potent anti-FGF2 activity and anti-VEGF-expression activity

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Provide signed written informed consent.
  2. Male or female 55 years of age or older on the date of signing the consent and able and willing to comply with all treatment and study procedures.
  3. Diagnosis of exudative age-related macular degeneration in the study eye, for which previous standard treatment with intravitreal anti-vascular endothelial growth factor agents (at least 4 injections over the past 8 months) has demonstrated incomplete resolution of exudation, as assessed by spectral domain optical coherence tomography.
  4. Presence of macular edema or subretinal fluid.
  5. Absence of central atrophy or retinal epithelial tear in the fovea or any condition preventing visual acuity improvement in the study eye.
  6. Visual acuity of 78 to 24 letters (20/32 to 20/320) in the study eye.
  7. Visual acuity of 24 letters (20/320) or better in the fellow eye.
  8. Reasonably clear media and some fixation in the study eye to allow for good quality tomography and fundus photography

Exclusion Criteria:

  • Ocular:

    1. Use of any of the following treatments or anticipated use of any of the following treatments to the study eye:

      1. Any intravitreal treatment within 4 weeks prior to Baseline (Visit 1).
      2. Intravitreal or periocular corticosteroid, within 90 days prior to Visit 1 (Day 1) and throughout the study.
      3. Fluocinolone acetonide intravitreal implant, within 12 months prior to Visit 1 (Day 1) and throughout the study.
