Brentuximab vedotin is a novel antibody-drug conjugate consisting of the anti-CD30 antibody cAC10 chemically conjugated to monomethylauristatin E, a potent antimicrotubule agent. Preliminary response rates of 75% in relapsed/refractory Hodgkin's lymphoma and 87% in relapsed/refractory systemic anaplastic large-cell lymphoma were recently reported in large Phase II trials. ⋯ The impressive response rates and limited toxicity of brentuximab vedotin are very promising for relapsed/refractory patients with few treatment options. In addition, the possibilities for incorporation into front-line therapies for both Hodgkin's lymphoma and systemic anaplastic large-cell lymphoma are intriguing.
