A combination of anti‐interleukin 6 murine monoclonal antibody with dexamethasone and high‐dose melphalan induces high complete response rates in advanced multiple myeloma

Abstract
To improve the complete response (CR) rate in advanced multiple myeloma (MM) without increasing the toxicity of high‐dose therapy, we have used a new conditioning regimen. A combination of BE‐8 [an anti‐interleukin 6 (IL‐6) murine monoclonal antibody] and dexamethasone followed by high‐dose melphalan (220 mg/m2) and autologous stem cell transplantation was used to treat a series of 16 patients with advanced multiple myeloma. A strong inhibition of IL‐6 activity evaluated by quantification of C‐reactive protein was observed in all patients and was correlated with the high CR rate achieved with this combination therapy.
