Brentuximab vedotin is an anti-CD30 monoclonal antibody conjugated to the cytotoxic drug monomethyl auristatin E. It is currently evaluated in combination with multi-agent chemotherapy as frontline treatment of systemic ALCL (sALCL) and other CD30-positive mature T cell and NK cell lymphomas. Preliminary results of this phase 1 study have been presented at the 2012 ASH Annual Meeting: 26 patients have been treated with combination brentuximab vedotin and CHP. Nineteen of 26 patients had a diagnosis of sALCL and 7 patients had a diagnosis of another mature Tor NK-cell lymphoma (EATL, n=1). The maximum tolerated dose of brentuximab vedotin in combination with CHP was not exceeded at 1.8 mg/kg IV. Adverse events were manageable. All patients achieved an objective response, with 23 patients (88%) achieving a complete response (CR). All 7 non-sALCL patients achieved a CR.
