In the two 96-week controlled clinical trials in neovascular age-related macular degeneration, the ATE rate in the pooled brolucizumab arms was 4.5% (33/730) compared with 4.7% (34/729) in the pooled aflibercept arms. Arterial thromboembolic events were defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause).^[Ref]

• Common (1% to 10%): Hypersensitivity

Hypersensitivity included urticaria, rash, pruritus, and erythema.

Immunologic

• Very common (10% or more): Anti-drug antibodies^[Ref]

Pretreatment anti-brolucizumab (the active ingredient contained in Beovu) antibodies were detected in 36% to 52% of treatment naive patients. After dosing, anti-brolucizumab antibodies were detected in 53% to 67% of patients. Intraocular inflammation was observed in 6% of patients with anti-brolucizumab antibodies. The significance of anti-brolucizumab antibodies on safety and efficacy is unknown. As with all therapeutic proteins, the detection of an immune response is highly dependent on the sensitivity and specificity of the assay, sample handling, timing of sample collection, concomitant medications, and underlying disease. Comparing the incidence of antibody formation to other products may be misleading.^[Ref]
