Abstract: 601342 Disclosed is a bispecific antibody or bispecific antibody fragment thereof that specifically binds to IL-13 and IL4, wherein: the bispecific antibody or bispecific antibody fragment thereof comprises two light chains and two heavy chains; the light chains comprise an outer variable light chain domain linked to an inner variable light chain domain which is linked to a constant light chain domain (CL), and the heavy chains comprise an outer variable heavy chain domain linked to an inner variable heavy chain domain which is linked to a constant heavy chain domain (CH1); the bispecific antibody or bispecific antibody fragment thereof has a higher affinity for IL-13 and/or IL-4 than the antibody from which the variable light chain or variable heavy chain domain or complementarity determining regions (CDRs) were derived; and (e) the outer variable light chain domain comprises the amino acid sequences RASESVDSYGQSYMH (CDR1; SEQ ID NO: 8), LASNLES (CDR2; SEQ ID NO: 9), and QQNAEDSRT (CDR3; SEQ ID NO: 10), the inner variable light chain domain comprises the amino acid sequences HASQNIDVWLS (CDR1; SEQ ID NO: 14), KASNLHTG (CDR2; SEQ ID NO: 15), and QQAHSYPFT (CDR3; SEQ ID NO: 16), the outer variable heavy chain domain comprises the amino acid sequences GFSLTDSSIN (CDR1; SEQ ID NO: 11), DGRID (CDR2; SEQ ID NO: 12), and DGYFPYAMDF (CDR3; SEQ ID NO: 13), and the inner variable heavy chain domain comprises the amino acid sequences GYSFTSYWIH (CDR1; SEQ ID NO: 17), IDPSDGETR (CDR2; SEQ ID NO: 18), and LKEYGNYDSFYFDV (CDR3; SEQ ID NO: 19); (f) the outer variable light chain domain comprises the amino acid sequences RASESVDSYGQSYMH (CDR1; SEQ ID NO: 8), LASNLES (CDR2; SEQ ID NO: 9), and QQNAEDSRT (CDR3; SEQ ID NO: 10), the inner variable light chain domain comprises the amino acid sequences HASQNIDVWLS (CDR1; SEQ ID NO: 14), KASNLHTG (CDR2; SEQ ID NO: 15), and QQAHSYPFT (CDR3; SEQ ID NO: 16), the outer variable heavy chain domain comprises the amino acid sequences GFSLTDSSIN (CDR1; SEQ ID NO: 11), DGRID (CDR2; SEQ ID NO: 12), and DGYFPYAMDF (CDR3; SEQ ID NO: 13), and the inner variable heavy chain domain comprises the amino acid sequences GYSFTSYWIH (CDR1; SEQ ID NO: 20), IDASDGETR (CDR2; SEQ ID NO: 21), and LKEYGNYDSFYFDV (CDR3; SEQ ID NO: 22); (g) the outer variable light chain domain comprises the amino acid sequences HASQNIDVWLS (CDR1; SEQ ID NO: 14), KASNLHTG (CDR2; SEQ ID NO: 15), and QQAHSYPFT (CDR3; SEQ ID NO: 16), the inner variable light chain domain comprises the amino acid sequences RASESVDSYGQSYMH (CDR1; SEQ ID NO: 8), LASNLES (CDR2; SEQ ID NO: 9), and QQNAEDSRT (CDR3; SEQ ID NO: 10), the outer variable heavy chain domain comprises the amino acid sequences GYSFTSYWIH (CDR1; SEQ ID NO: 17), IDPSDGETR (CDR2; SEQ ID NO: 18), and LKEYGNYDSFYFDV (CDR3; SEQ ID NO: 19), and the inner variable heavy chain domain comprises the amino acid sequences GFSLTDSSIN (CDR1; SEQ ID NO: 11), DGRID (CDR2; SEQ ID NO: 12), and DGYFPYAMDF (CDR3; SEQ ID NO: 13); or (h) the outer variable light chain domain comprises the amino acid sequences HASQNIDVWLS (CDR1; SEQ ID NO: 14), KASNLHTG (CDR2; SEQ ID NO: 15), and QQAHSYPFT (CDR3; SEQ ID NO: 16), the inner variable light chain domain comprises the amino acid sequences RASESVDSYGQSYMH (CDR1; SEQ ID NO: 8), LASNLES (CDR2; SEQ ID NO: 9), and QQNAEDSRT (CDR3; SEQ ID NO: 10), the outer variable heavy chain domain comprises the amino acid sequences GYSFTSYWIH (CDR1; SEQ ID NO: 20), IDASDGETR (CDR2; SEQ ID NO: 21), and LKEYGNYDSFYFDV (CDR3; SEQ ID NO: 22), and the inner variable heavy chain domain comprises the amino acid sequences GFSLTDSSIN (CDR1; SEQ ID NO: 11), DGRID (CDR2; SEQ ID NO: 12), and DGYFPYAMDF (CDR3; SEQ ID NO: 13).
