Abstract

The present invention concerns compositions and methods of use of bispecific antibodies comprising at least one anti-TNF-α antibody or antigen-binding fragment thereof and at least one anti-IL-6 antibody or antigen-binding fragment thereof. Preferably, the bispecific antibody is in the form of a DNL® complex. The anti-TNF-α or anti-IL-6 antibodies may comprise specific CDR sequences disclosed herein. The compositions and methods are of use to treat autoimmune disease, immune system dysfunction or inflammatory disease, as disclosed herein.
