The present invention provides a human PD-1 antibody, an antigen-binding fragment thereof, and a medical application thereof, and further provides a chimeric antibody comprising a complementarity-determining region (CDR) of the antibody, a humanized antibody, a pharmaceutical composition comprising the human PD-1 antibody and the antigen-binding fragment thereof, and a purpose of the antibody in preparing medicine for treating diseases or symptoms.

Pd-1 antibody, antigen-binding fragment thereof, and medical application thereof

The present invention is directed to bi-specific diabodies that comprise two or more polypeptide chains and which possess at least one Epitope-Binding Site that is immunospecific for an epitope of PD-1 and at least one Epitope-Binding Site that is immunospecific for an epitope of LAG-3 (i.e., a "PD-I x LAG-3 bi-specific diabody"). More preferably, the present invention is directed to bi-specific diabodies that comprise four polypeptide chains and which possess two Epitope-Binding Sites that are immunospecific for one (or two) epitope(s) of PD-1 and two Epitope-Binding Site that are immunospecific for one (or two) epitope(s) of LAG-3 (i.e., a "PD-1 x LAG-3 bi-specific, tetra-valent diabody").

Covalently bonded diabodies having immunoreactivity with PD-1 and LAG-3, and methods of use thereof

The present invention is directed to selected anti-PD-1 antibodies capable of binding to both cynomolgus monkey PD-1 and to human PD-1 : PD-1 mAb 1, PD-1 mAb 2, PD-1 mAb 3, PD-1 mAb 4, PD-1 mAb 5, PD-1 mAb 6, PD-1 mAb 7, PD-1 mAb 8, PD-1 mAb 9, PD-1 mAb 10, PD-1 mAb 11, PD-1 mAb 12, PD-1 mAb 13, PD-1 mAb 14, or PD-1 mAb 15, and to humanized and chimeric versions of such antibodies. The invention additionally pertains to PD-1 -binding molecules that comprise PD-1 binding fragments of such anti-PD-1 antibodies, immunocongugates, and to bispecific molecules, including diabodies, BiTEs, bispecific antibodies, etc., that comprise (i) such PD-1 -binding fragments, and (ii) a domain capable of binding an epitope of a molecule involved in regulating an immune check point present on the surface of an immune cells. The present invention also pertains to methods of using molecules that bind PD-1 for stimulating immune responses, as well as methods of detecting PD-1.

PD-1-binding molecules and methods of use thereof

The instant disclosure provides antibodies that specifically bind to human PD-1 and antagonize PD-1 function. Also provided are pharmaceutical compositions comprising these antibodies, nucleic acids encoding these antibodies, expression vectors and host cells for making these antibodies, and methods of treating a subject using these antibodies.

Anti-pd-1 antibodies and methods of use thereof

The present invention is directed to bispecific molecules (e.g., diabodies, bispecific antibodies, trivalent binding molecules, etc.) that possess at least one epitope-binding site that is immunospecific for an epitope of PD-1 and at least one epitope-binding site that is immunospecific for an epitope of CTLA-4 (i.e., a "PD-1 x CTLA-4 bispecific molecule"). The PD-1 x CTLA-4 bispecific molecules of the present invention are capable of simultaneously binding to PD-1 and to CTLA-4, particularly as such molecules are arrayed on the surfaces of human cells. The invention is directed to pharmaceutical compositions that contain such PD-1 x CTLA-4 bispecific molecules, and to methods involving the use of such bispecific molecules in the treatment of cancer and other diseases and conditions. The present invention also pertains to methods of using such PD-1 x CTLA-4 bispecific molecules to stimulate an immune response.

Bispecific molecules having immunoreactivity with pd-1 and ctla-4, and methods of use thereof

Provided herein are antibodies that selectively bind to PD-1 and its isoforms and homologs, and compositions comprising the antibodies. Also provided are methods of using the antibodies, such as therapeutic and diagnostic methods.

Anti-pd-1 antibodies, compositions comprising anti-pd-1 antibodies and methods of using anti-pd-1 antibodies

Provided herein are antibodies that selectively bind to LAG3 and its isoforms and homologs, and compositions comprising the antibodies. Also provided are methods of using the antibodies, such as therapeutic and diagnostic methods.

Anti-lag3 antibodies, compositions comprising anti-lag3 antibodies and methods of making and using anti-lag3 antibodies

Provided herein are antibodies that selectively bind to Tim-3 and its isoforms and homologs, and compositions comprising the antibodies. Also provided herein are antibodies that selectively bind to PD-1 and its isoforms and homologs, and compositions comprising the antibodies. In addition, provided herein are bi-specific antibodies and antigen binding constructs that selectively bind to Tim-3 and/or PD-1, their isoforms and homologs, and compositions comprising the antibodies and antigen binding constructs. Also provided are methods of using the antibodies, such as therapeutic and diagnostic methods.

Pd-1/tim-3 bi-specific antibodies, compositions thereof, and methods of making and using the same

Provided herein are antibodies that selectively bind to EpCAM and its isoforms and homologs, and compositions comprising the antibodies. Also provided are methods of using the antibodies, such as therapeutic and diagnostic methods.

ANTI-EpCAM ANTIBODIES, COMPOSITIONS COMPRISING ANTI-EpCAM ANTIBODIES AND METHODS OF MAKING AND USING ANTI-EpCAM ANTIBODIES

The present disclosure relates to antibodies that selectively bind to folate receptor alpha (FOLR1) and its isoforms and homologs, and compositions comprising the antibodies. Also provided are methods of using the antibodies, such as therapeutic and diagnostic methods.

Anti-folate receptor antibodies, compositions comprising anti-folate receptor antibodies and methods of making and using anti-folate receptor antibodies
