Abstract
The present invention generally relates to antibodies that bind to CD3, including multispecific antibodies e.g. for activating T cells. In addition, the present invention relates to polynucleotides encoding such antibodies, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the antibodies, and to methods of using them in the treatment of disease.
Claims4

- 2, a HCDR 2 of SEQ ID NO:
- 4, and a HCDR 3 of SEQ ID NO:
- 10,
- (b) a VH comprising a HCDR 1 of SEQ ID NO:
- 2, a HCDR 2 of SEQ ID NO:
- 4, and a HCDR 3 of SEQ ID NO:
- 12,
- (c) a VH comprising a HCDR 1 of SEQ ID NO:
- 2, a HCDR 2 of SEQ ID NO:
- 5, and a HCDR 3 of SEQ ID NO:
- 9,
- (d) a VH comprising a HCDR 1 of SEQ ID NO:
- 3, a HCDR 2 of SEQ ID NO:
- 6, and a HCDR 3 of SEQ ID NO:
- 11, and
- (e) a VH comprising a HCDR 1 of SEQ ID NO:
- 3, a HCDR 2 of SEQ ID NO:
- 7, and a HCDR 3 of SEQ ID NO:
- 13,
- and
- (ii) a light chain variable region (VL) comprising a light chain complementarity determining region (LCDR) 1 of SEQ ID NO:
- 20, a LCDR 2 of SEQ ID NO:
- 21 and a LCDR 3 of SEQ ID NO:
- 22, or an antigen binding domain fragment thereof.
An antibody that specifically binds to CD3, wherein the antibody comprises a first antigen binding domain comprising
- a VH sequence selected from the group consisting of SEQ ID NO:
- 16, SEQ ID NO:
- 18, SEQ ID NO:
- 15, SEQ ID NO:
- 17 and SEQ ID NO:
- 19, and
- a VL sequence of SEQ ID NO:
- 23, or an antigen binding domain fragment thereof.
