Abstract

BACKGROUND: Ranibizumab--a recombinant, humanized, monoclonal antibody Fab that neutralizes all active forms of vascular endothelial growth factor A--has been evaluated for the treatment of neovascular age-related macular degeneration. METHODS: In this multicenter, 2-year, double-blind, sham-controlled study, we randomly assigned patients with age-related macular degeneration with either minimally classic or occult (with no classic lesions) choroidal neovascularization to receive 24 monthly intravitreal injections of ranibizumab (either 0.3 mg or 0.5 mg) or sham injections. The primary end point was the proportion of patients losing fewer than 15 letters from baseline visual acuity at 12 months. RESULTS: We enrolled 716 patients in the study. At 12 months, 94.5% of the group given 0.3 mg of ranibizumab and 94.6% of those given 0.5 mg lost fewer than 15 letters, as compared with 62.2% of patients receiving sham injections (P<0.001 for both comparisons). Visual acuity improved by 15 or more letters in 24.8% of the 0.3-mg group and 33.8% of the 0.5-mg group, as compared with 5.0% of the sham-injection group (P<0.001 for both doses). Mean increases in visual acuity were 6.5 letters in the 0.3-mg group and 7.2 letters in the 0.5-mg group, as compared with a decrease of 10.4 letters in the sham-injection group (P<0.001 for both comparisons). The benefit in visual acuity was maintained at 24 months. During 24 months, presumed endophthalmitis was identified in five patients (1.0%) and serious uveitis in six patients (1.3%) given ranibizumab. CONCLUSIONS: Intravitreal administration of ranibizumab for 2 years prevented vision loss and improved mean visual acuity, with low rates of serious adverse events, in patients with minimally classic or occult (with no classic lesions) choroidal neovascularization secondary to age-related macular degeneration.

  • Ranibizumab anti-Fab immunoreactivity in treatment-naïve patients was between 0-0.9% in the MARINA and ANCHOR trials.

    “Ranibizumab anti-Fab immunoreactivity in treatment-naïve patients was between 0–0.9% in the MARINA and ANCHOR trials [30, 31].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [30]

    The Adverse Events section reports baseline anti-ranibizumab immunoreactivity of 0% and 0.9% in the two ranibizumab groups of MARINA, before study treatment. The Discussion identifies ANCHOR as a separate trial but does not give its baseline immunoreactivity rates, so this source supports the MARINA portion, not the stated range for both trials. No page numbers were supplied for these passages. (LLM, conf=0.86)

  • The MARINA and ANCHOR trials with ranibizumab showed an incidence of 0.05% for inflammation.

    “The MARINA and ANCHOR trials with ranibizumab showed an incidence of 0.05% [30, 31], and a subsequent comparison study of ranibizumab and bevacizumab for neovascular AMD reported rates of 0.16% for ranibizumab and 0.5% for bevacizumab [32].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [30]

    The Adverse Events section reports 0.05% per injection in MARINA, but that figure is for presumed endophthalmitis, not inflammation generally; Table 2 records ocular inflammation separately. The Discussion mentions ANCHOR but does not give it a 0.05% rate. Page numbers are unavailable in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Regardless of anti-VEGF agent, pre-treatment ADA titers have not been shown to have any clinically relevant difference in BCVA outcomes.

    “Regardless of anti-VEGF agent, pre-treatment ADA titers have not been shown to have any clinically relevant difference in BCVA outcomes [30, 33, 41, 43].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [30]

    The Adverse Events section (page unavailable) reports no clinically relevant differences in efficacy between patients with and without immunoreactivity to ranibizumab. It also reports antibody testing at baseline, but does not establish that pre-treatment ADA titers predict BCVA outcomes, and this study does not assess other anti-VEGF agents. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Repeated intravitreal injections of anti-VEGF therapies effectively slow vision loss in the majority of treatment-compliant patients with wet AMD.

    “Repeated intravitreal (IVT) injections of anti-VEGF therapies effectively slow vision loss in the majority of treatment-compliant patients with wet AMD. 7 – 13”

    From Design and Characterization of a Novel Intravitreal Dual-Transgene Genetic Medicine for Neovascular Retinopathies (2024) · cites this paper as [12]

    The Study Treatment section describes monthly intravitreal ranibizumab injections, and Primary and Secondary End Points reports that 90.0–94.6% of recipients lost fewer than 15 letters at 12 or 24 months, compared with 52.9–62.2% of sham-injection recipients. This supports slowed vision loss for most patients receiving ranibizumab, but this trial alone does not establish the result for anti-VEGF therapies generally or specifically for a treatment-compliant subgroup. (LLM, conf=0.86)

  • In the ANCHOR and MARINA studies, 8-14% of eyes gained at least 15 letters during months 4 to 12.

    “In the ANCHOR and MARINA studies, 8-14% of eyes gained 415 letters during months 4 to 12. [22][23][24]”

    From Defining response to anti-VEGF therapies in neovascular AMD (2015) · cites this paper as [22]

    The Primary and Secondary End Points section reports that approximately one quarter to one third of ranibizumab-treated patients gained at least 15 letters at 12 months. It does not report an 8–14% gain during months 4 to 12, and this paper reports the MARINA study, not ANCHOR. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
