主权项

1. A method of treatment of a patient suffering from a disease or disorder which is cancer or a vascular disease, said method comprising the step of administering a bispecific antibody to a patient in the need of such treatment, said bispecific antibody being one that binds specifically to human vascular endothelial growth factor (VEGF) and human angiopoietin-2 (ANG-2) and comprises a first antigen-binding site that specifically binds to human VEGF and a second antigen-binding site that specifically binds to human ANG-2, wherein:
i) said antigen-binding sites each comprise an antibody heavy chain variable domain and an antibody light chain variable domain; ii) said first antigen-binding site comprises in the heavy chain variable domain:
a CDR3 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 9, SEQ ID NO: 17, and SEQ ID NO: 94;a CDR2 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 2, SEQ ID NO: 10, SEQ ID NO: 18, and SEQ ID NO: 95;and a CDR1 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:3, SEQ ID NO: 11, SEQ ID NO: 19, and SEQ ID NO: 96, andin the light chain variable domain:a CDR3 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 4, SEQ ID NO: 12, SEQ ID NO: 20, and SEQ ID NO: 97,a CDR2 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:5, SEQ ID NO: 13, SEQ ID NO: 21, and SEQ ID NO: 98; anda CDR1 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:6, SEQ ID NO: 14, SEQ ID NO: 22, and SEQ ID NO: 99; and iii) said second antigen-binding site comprises in the heavy chain variable domain:
a CDR3 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 25, SEQ ID NO: 38, SEQ ID NO: 46, SEQ ID NO: 54, SEQ ID NO: 62, SEQ ID NO: 70, SEQ ID NO: 78, and SEQ ID NO: 86;a CDR2 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 26, SEQ ID NO: 39, SEQ ID NO: 47, SEQ ID NO: 55, SEQ ID NO: 63, SEQ ID NO: 71, SEQ ID NO: 79, and SEQ ID NO: 87; anda CDR1 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:27, SEQ ID NO: 40, SEQ ID NO: 48, SEQ ID NO: 56, SEQ ID NO: 64, SEQ ID NO: 72, SEQ ID NO: 80, and SEQ ID NO: 88; andin the light chain variable domain:a CDR3 region having an amino acid sequence selected from the group consisting of: SEQ ID NO: 28, SEQ ID NO: 28 with the mutations T92L, H93Q and W94T, SEQ ID NO: 41, SEQ ID NO: 49, SEQ ID NO: 57, SEQ ID NO: 65, SEQ ID NO: 73, SEQ ID NO: 81, and SEQ ID NO: 89;a CDR2 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:29, SEQ ID NO: 42, SEQ ID NO: 50, SEQ ID NO: 58, SEQ ID NO: 66, SEQ ID NO: 74, SEQ ID NO: 82 and SEQ ID NO: 90; anda CDR1 region having an amino acid sequence selected from the group consisting of: SEQ ID NO:30, SEQ ID NO: 43, SEQ ID NO: 51, SEQ ID NO: 59, SEQ ID NO: 67, SEQ ID NO: 75, SEQ ID NO: 83, and SEQ ID NO: 91.
