Benefits of technology

[0008]The present invention discloses combined therapeutic treatments for B-cell lymphomas, and reports the benefits of treating relapsed or refractory B-cell lymphomas with chimeric and radiolabeled anti-CD20 antibodies. In particular, it has been found that treatment with anti-CD20 antibody provides a beneficial synergistic effect when administered in combination with cytokines, radiotherapy, myeloablative therapy, or chemotherapy. Surprisingly, patients who had prior bone marrow or stem cell transplantation had an unexpected increase in the over-all response rate when compared with patients with no prior therapy.

Problems solved by technology

However, while anti-CD20 antibodies and, in particular, RITUXAN® (U.S.; in Britain, MABTHERA®; in general Rituximab), have been reported to be effective for treatment of B-cell lymphomas, such as non-Hodgkin's lymphoma, the treated patients are often subject to disease relapse.

Embodiment Construction

[0009]This invention encompasses combined therapeutic regimens for the treatment of B-cell lymphomas. In general, such methods include a method for treating relapsed B-cell lymphoma, where a patient having prior treatment for lymphoma has relapsed and is administered a therapeutically effective amount of a chimeric anti-CD20 antibody. Such prior treatments can include, for example, previous treatment with anti-CD20 antibodies, treatments which included a bone marrow or stem cell transplantation, radiotherapy and chemotherapy. The previous chemotherapy may be selected from a wide group of chemotherapeutic agents and combination regimens, including CHOP, ICE, Mitozantrone, Cytarabine, DVP, ATRA, Idarubicin, hoelzer chemotherapy regime, La La chemotherapy regime, ABVD, CEOP, 2-CdA, FLAG & IDA with or without subsequent G-CSF treatment), VAD, M & P, C-Weekly, ABCM, MOPP and DHAP.

[0010]Also included in the methods of the invention are methods for treating a subject having B-cell lymphoma...
