Brentuximab vedotin in Hodgkin lymphoma and anaplastic large-cell lymphoma: an evidence-based review.

Hodgkin lymphoma (HL) and anaplastic large-cell lymphoma (ALCL) account for ~10% and 2%-3% of all cases of lymphoid neoplasms, respectively. Up to 30% of patients with HL are refractory or relapse after first-line therapy, and elderly patients with HL represent a subgroup of patients with suboptimal responses to the currently available treatments. Five-year overall survival for ALCL patients is 50%-80% with conventional chemotherapy. Therefore, new therapeutic approaches are needed for these groups of patients. Brentuximab vedotin is a chimeric IgG1 anti-CD30 antibody-drug conjugate that has all the features that are necessary to make a substantive difference with the standard therapies in patients with HL and ALCL: a novel mechanism of action, single-agent activity, non-cross-resistance, and safety both in the relapsed-refractory and in the front-line setting. This review provides an update of the results of the most relevant clinical trials including brentuximab vedotin for patients with HL and ALCL conducted to date.
