摘要：
Discloses a bispecific antibody fusion protein which binds human OX40 and human serum albumin comprising: a heavy chain comprising, in sequence from the N-terminal, a first heavy chain variable domain (VH1), a CHI domain and a second heavy chain variable domain (VH2), a light chain comprising, in sequence from the N-terminal, a first light chain variable domain (VL1), a CL domain and a second light chain variable domain (VL2), wherein said heavy and light chains are aligned such that VH1 and VL1 form a first antigen binding site and VH2 and VL2 form a second antigen binding site, wherein the antigen bound by the first antigen binding site is human OX40 and the antigen bound by the second antigen binding site is human serum albumin, wherein the first variable domain of the heavy chain (VH1) comprises the sequence given in SEQ ID NO:1 for CDR-H1, the sequence given in SEQ ID NO:2 for CDR-H2 and the sequence given in SEQ ID NO:3 for CDR-H3 and the first variable domain of the light chain (Vd) comprises the sequence given in SEQ ID NO:4 for CDR-L1, the sequence given in SEQ ID NO:5 for CDR-L2 and the sequence given in SEQ ID NO:6 for CDR-L3, wherein the second heavy chain variable domain (VH2) has the sequence given in SEQ ID NO:11 and the second light chain variable domain (VL2) has the sequence given in SEQ ID NO: 12 and the second heavy chain variable domain (VH2) and second light chain variable domain (VL2) are linked by a disulphide bond, wherein the sequences are as defined in the complete specification.
