The present invention provides novel CD47 antibodies or immunologically active fragments thereof that have low immunogenicity in humans and cause low or no level of red blood cell depletion or hemagglutination, as well as pharmaceutical compositions containing such antibodies that can be used for treatment diseases mediated by CD47 or inhibition of phagocytosis or platelet aggregation.

CD47 monoclonal antibodies and uses thereof

Provided are anti-GM-CSF antibodies or fragments thereof including humanized antibodies and fragments. Also provided are uses of the antibodies and fragments for therapeutic, diagnostic and prognostic purposes. Therapeutic uses of the antibodies and fragments, for example include the treatment of inflammatory and autoimmune diseases and disorders.

Anti-GM-CSF antibodies and uses thereof

Provided are anti-CD73 antibodies or fragments thereof. The antibodies or fragments therefore include a VH CDR1 of SEQ ID NO: 1, a VH CDR2 of SEQ ID NO: 2, a VH CDR3 of SEQ ID NO: 3, a VL CDR1 of SEQ ID NO: 4, a VL CDR2 of SEQ ID NO: 5, and a VL CDR3 of SEQ ID NO: 6, or variants of each thereof. More generally, antibodies or fragments thereof are described which have specificity to one or more amino acid residues selected from the C-terminal half of a human CD73 protein, such as those in the C-terminal domains. Specific epitope amino acids in these domains include Y345, D399, E400, R401 and R480. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer are also provided.

Anti-CD73 antibodies and uses thereof

The present disclosure provides antibodies that bind Lymphocyte Activation Gene-3 (LAG-3). Also provided are methods of stimulating an immune response, inhibiting growth of tumor cells, and treating an autoimmune, inflammatory, or viral disease.

Anti-LAG-3 antibodies and uses thereof

Provided are fusion molecule having a PD-L1 inhibitor fused to a human IL-7 protein or fragment thereof through a peptide linker. The disclosed fusion molecules exhibited synergistic anti-tumor effects.

Anti-PD-L1 antibody and IL-7 fusions

Provided are anti-PD-L1 antibodies or fragments thereof. The antibodies or fragments thereof specifically bind to the immunoglobulin C domain of the PD-L1 protein. In various example, the antibodies or fragments thereof include a VH CDR1 of SEQ ID NO: 1, a VH CDR2 of SEQ ID NO: 116, a VH CDR3 of SEQ ID NO: 117, a VL CDR1 of SEQ ID NO: 4, a VL CDR2 of SEQ ID NO: 5, and a VL CDR3 of SEQ ID NO: 6, or variants of each thereof. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer and infectious diseases are also provided.

Anti-PD-L1 antibodies and uses thereof

Provided are bispecific antibodies capable of binding to human CD73 protein and human PD-L1 protein. These bispecific antibodies are effective in treating cancer.

Anti-CD73 anti-PD-L1 bispecific antibodies

The present disclosure provides antibodies and fragments thereof having specificity to a human T cell immunoreceptor with Ig and ITIM domains (TIGIT) protein. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer and viral infections are also provided.

Antibodies to T cell immunoreceptor with IG and ITIM domains (TIGIT) and uses thereof

Provided are anti-PD-L1 antibodies or fragments thereof. The antibodies or fragments thereof specifically bind to the immunoglobulin C domain of the PD-L1 protein. In various example, the antibodies or fragments thereof include a VH CDR1 of SEQ ID NO: 1, a VH CDR2 of SEQ ID NO: 2, a VH CDR3 of SEQ ID NO: 3, a VL CDR1 of SEQ ID NO: 4, a VL CDR2 of SEQ ID NO: 5, and a VL CDR3 of SEQ ID NO: 6, or variants of each thereof. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer and infectious diseases are also provided.
