Tositumomab is a monoclonal antibody derived from immortalized mouse cells. It is a IgG2a anti-CD20 antibody and is covalently bound to Iodine 131. 131I emits both beta and gamma radiation, and is broken down rapidly in the body.

Clinical trials have established the efficacy of tositumomab in patients with relapsed or chemotherapy/rituxan refractory follicular lymphoma.

It is manufactured by Corixa. It sells in the U.S. under the trade name Bexxar.
