Current Role and Emerging Evidence for Bruton Tyrosine Kinase Inhibitors in the Treatment of Mantle Cell Lymphoma.

The Bruton tyrosine kinase inhibitors (BTKi), acalabrutinib, ibrutinib, and zanubrutinib, are all approved in the United States for the treatment of relapsed mantle cell lymphoma (MCL). BTKi as a class have become the preferred therapy for most of the patients with relapsed MCL, and ongoing clinical trials are evaluating whether combining BTKi with other targeted agents may deepen response and further improve outcomes. Emerging evidence supports the efficacy of BTKi-containing combinations as frontline treatment, and clinical studies to define the role of this class of drugs for newly diagnosed patients with MCL are in progress.
