Abstract: The present disclosure provides an anti-PD-L1/anti-4-1BB bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between 4-1BB and its ligand. The bispecific antibody may have high binding affinity to both of a PD-L1 protein and a 4-1BB protein.

Abstract: The present invention relates to new antibody-drug conjugates (ADCs) targeting ROR1, active metabolites of such ADCs, methods for preparation of such ADCs, uses for such ADCs in treatment and/or prevention of illnesses, and uses for such ADCs in production of drugs for treatment and/or prevention of diseases, more specifically diseases associated with over-expression of ROR1, for example cancer. More specifically, the present invention relates to an antibody-drug conjugate comprising an antibody that binds to ROR1 or an antigen-binding fragment thereof, and a pharmaceutical composition comprising the same.

Abstract: The present invention relates to a bi-specific antibody that specifically binds to alpha-synuclein and IGF1R, and use of the bi-specific antibody for treating or diagnosing synucleinopathies associated with alpha-synuclein or alpha-synuclein aggregates. The IGF1R portion of the bi-specific antibody acts as a shuttle to penetrate the blood brain barrier, allowing the alpha-synuclein portion to exert its action in the brain. Further, the half-life of the bi-specific antibody may be extended to maintain efficacy over time.
