Objective: To identify and analyze postmarketing case reports of elevated blood pressure (BP) associated with erenumab use.
Methods: A retrospective analysis of postmarketing (spontaneous) case reports of erenumab-associated elevated BP submitted to the FDA Adverse Event Reporting System from May 17, 2018 through April 30, 2020. A case of elevated BP was defined as (a) an initiation of a pharmacological intervention or emergency department visit or hospitalization for emergent de novo or worsening of preexisting hypertension, or (b) BP measurement of ≥140 mm Hg systolic or ≥90 mm Hg diastolic with or without baseline BP measurement reported. Reports of elevated BP associated with erenumab use were analyzed for baseline and demographic information, latency, drug-event causal association, and clinical outcome.
Results: Sixty-one cases of elevated BP were identified, 86% (49/57) were women and the median age was 56 [range 24-88] years. Forty-one cases were associated with a serious outcome per regulatory criteria, including seven that specified hospitalization. No case reported an outcome of death. The median systolic BP increase was 39 (interquartile range (IQR) 32, 59) mm Hg and median diastolic BP increase was 28 (IQR 18, 41) mm Hg. A total of 27/61 (44%) cases reported treatment for elevated BP (i.e., pharmacologic intervention or emergency department visit/hospitalization). Elevated BP occurred most frequently (28/61, 46%) within a week of the first dose of erenumab. Nineteen cases (19/61, 31%) reported a history of preexisting hypertension.
Conclusions: This case series suggest an association between elevated BP and use of erenumab. In light of our findings, the erenumab (Aimovig) prescribing information was amended to include hypertension in the Warnings and Precautions section.
