Abstract: The present application provides CLDN18.2 antibodies or antigen binding fragments thereof and related CLDN18.2/CD3 bispecific antibodies, as well as corresponding nucleic acids encoding same, vectors comprising such nucleic acids, host cells transfected with such nucleic acids or vectors. The present application further relates to isolated CLDN18.2 antibodies or antigen binding fragments thereof and related CLDN18.2/CD3 bispecific antibodies, pharmaceutical compositions comprising such antibodies, antigen binding fragments, bispecific antibodies, nucleic acids, vectors, or host cells and optionally a pharmaceutically acceptable carrier, and methods of treating cancer in a subject in need thereof by administering such pharmaceutical compositions. The cancers treated in accordance with the present application include CLDN18.2-positive cancers, such as, inter alia, gastric cancer and pancreatic cancer.

Abstract: Provided herein are novel Glypican 3 (GPC3) antibodies or antigen binding fragments and GPC3/CD3 bispecific antibodies. The present application also provides chimeric anti-gen receptors comprising the antibodies or antigen-binding fragments, related CAR-T cells, and preparation methods and uses of the same. The present application further provides pharmaceutical compositions comprising GPC3 antibodies or antigen binding fragments, related GPC3/CD3 bispecific antibodies, related GPC3 CAR or CAR-T cells, and methods of treating cancer in a subject in need thereof by administering the Glypican 3 (GPC3) antibodies or antigen binding fragments, the bispecific antibodies, the chimeric antigen receptors, the CAR-T cells, or the pharmaceutical compositions. The cancers treated in accordance with the application include Glypican-3-positive cancers.

Abstract: The present invention provides novel CD3 antigen binding fragments with particularly advantageous properties such as producibility, stability, binding affinity, biological activity, specific targeting of certain T cells, targeting efficiency, remaining tumor cell killing and reduced toxicity. The present invention also provides bispecific antigen binding molecules for activating T cells. In addition, the invention further provides methods of treating cancer in a subject in need thereof, comprising administering to the subject a pharmaceutical composition comprising the above said bispecific antigen binding molecules.

Abstract: Antibodies to SEB, fragments thereof, and compositions comprising such are provided. Therapies for staphylococcal infection are provided, as well as assays for identifying additional agents useful in such therapies. An isolated antibody, or an isolated antigen-binding fragment of an antibody, is provided which antibody or antigen-binding fragment binds to staphylococcal enterotoxin B (SEB) and which antibody or antigen-binding fragment comprises a heavy chain variable CDR3 comprising the sequence RIYYGNNGGVMDY (SEQ ID NO:30); ARTAGLLAPMDY (SEQ ID NO:31); ARDTMRKCYCELKLKPPAEHPGPA (SEQ ID NO:32) or VRDL YGDYVGRY A Y (SEQ ID NO:48).

Abstract: Humanized Antibodies to SEB, fragments thereof, and compositions comprising such are provided. Therapies for staphylococcal infections and diseases are also provided. The presently claimed invention was made by or on behalf of the below listed parties to a joint research agreement. The joint research agreement was in effect on or before the date the claimed invention was made and the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement.
