    Hypertension is a commonly noted adverse event for patients with chronic lymphocytic leukemia who are treated with ibrutinib in the clinical trial setting (incidence, 18%; grade ≥3 hypertension, 6%).1 In clinical practice settings, patterns of development of and management strategies for hypertension are less well understood. Thus, we aimed to describe patterns of development, management strategies, and long-term vascular consequences of hypertension associated with ibrutinib in the non–clinical trial setting.

    This multicenter cohort study took place at the Memorial Sloan Cancer Center in New York, New York; the Lombardi Cancer Center, Georgetown University Hospital, in Washington, DC; and the Abramson Cancer Center, University of Pennsylvania, in Philadelphia. It included patients treated with 420 mg of ibrutinib daily for at least 6 months outside of clinical trials; patients requiring dose reductions were excluded. Baseline cardiovascular comorbidities and medication regimens, sequential blood pressure (BP) measurements before and after ibrutinib exposure, adjustments to cardiovascular medication regimens, and development of cardiovascular complications were collected. Institutional review boards at all institutions approved the study, and informed consent was not required because of minimal risk to participants. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.
