Acalabrutinib, a second-generation and more selective Bruton's tyrosine kinase inhibitor, was developed to potentiate efficacy while minimizing ibrutinib-associated side effects. We undertook a systematic review and meta-analysis of randomized clinical trials to determine the risks of acalabrutinib-related cardiac toxicities in patients with chronic lymphocytic leukemia. Patients on acalabrutinib experienced higher risk of any-grade cardiac events (risk ratio, 1.75; p = 0.01) while there was a considerable trend toward statistical significance in the risk of any-grade atrial fibrillation (risk ratio, 2.56; p = 0.05). There was no significant increase in the risk of hypertension or high-grade cardiac events or atrial fibrillation in the acalabrutinib group.
