The present invention provides a
bispecific antibody comprising one or more
antigen-binding domains binding specifically to AXL
antigen, and one or more
antigen- binding domains binding specifically to PD-L1 antigen, the binding of which to AXL and / or PD-L1 antigen leads to its internalisation, as well as an antigen-binding fragment thereof binding specifically to AXL and / or PD-L1. The present invention provides also a
nucleic acid encoding such a
bispecific antibody, or antigen-binding fragment thereof, an
antibody-
drug conjugate comprising such a
bispecific antibody, or antigen-binding fragment thereof, and a pharmaceutical composition comprising such a bispecific
antibody, or antigen-binding fragment thereof, or such an
antibody-
drug conjugate, and a pharmaceutically acceptable
excipient or carrier. Further, the present invention provides such a bispecific antibody or such a conjugate or such a pharmaceutical composition for use in therapy, for use in the therapy of a
neoplasm, in particular a malignant
neoplasm, particularly a
neoplasm exhibiting
surface expression of AXL and / or PD-L1. The invention provides also a method of treating or preventing neoplasm or its
metastasis in an individual and a method of stimulating an immune response, comprising administering such a bispecific antibody, fragment, conjugate or pharmaceutical composition to the individual.
