Abstract
Recent therapeutic advances for mantle cell lymphoma (MCL) include inhibitors of Bruton’s tyrosine kinase (BTK), a critical component in the B-cell receptor signaling pathway [1, 2]. Remarkably, approximately two thirds of patients with relapsed/refractory (R/R) MCL treated with ibrutinib, the first-in-class BTK inhibitor, achieve a durable response [3–5]. However, ibrutinib treatment also commonly produces off-target adverse events (AEs) such as bleeding, atrial fibrillation, diarrhea, and infection.
