Abstract
The invention relates to multispecific antibodies, and antigen binding fragments thereof, that specifically bind to distinct Zika virus epitopes and potently neutralize infection of ZIKV. The invention also relates to nucleic acids that encode such antibodies and antibody fragments. In addition, the invention relates to the use of the antibodies and antibody fragments of the invention in prophylaxis and treatment of ZIKV infection.
Claims20
A method of preventing and/or treating Zika virus infection in a subject, the method comprises administering to a subject in need thereof a multispecific antibody, or an antigen binding fragment thereof, specifically binding to at least two distinct Zika virus epitopes, that comprises a first heavy chain comprising CDRH1, CDRH2, and CDRH3 amino acid sequences and a first light chain comprising CDRL1, CDRL2, and CDRL3 amino acid sequences, and a second heavy chain comprising CDRH1, CDRH2, and CDRH3 amino acid sequences and a second light chain comprising CDRL1, CDRL2, and CDRL3 amino acid sequences, each according to one of:
- (a) SEQ ID NOs:
- 1-5 and 7, respectively;
- (b) SEQ ID NOs:
- 1-4 and 6-7, respectively;
