The present invention relates to linkers having a group of propiolyl, substituted acryl (acryloyl), or disubstituted propanoyl, and using such linkers for the conjugation of compounds, in particular, cytotoxic agents to a cell-binding molecule.

Disclosed are anti-CD45 antibodies and antibody drug conjugates (ADCs) useful in therapeutic methods, including targeting CD45 expressing hematopoietic stem cells (HSCs) or immune cells prior to transplantation.

The present invention provides antibody drug conjugates, wherein an antibody or antibody fragment that specifically binds to human cKIT is linked to a drug moiety, optionally through a linker. The present invention further provides pharmaceutical compositions comprising the antibody drug conjugates; and methods of making and using such pharmaceutical compositions for ablating hematopoetic stem cells in a patient in need thereof.

The present disclosure provides antibody-drug conjugate structures, which include a cleavable linker that links the antibody to the drug and has a first enzymatically cleavable moiety and a second enzymatically cleavable moiety which includes a glycoside selected from a galactoside, a glucoside, a mannoside, a fucoside, O-GlcNAc, and O-GalNAc. The disclosure also encompasses compounds and methods for production of such conjugates, as well as methods of using the conjugates.

The present application relates to a conjugate comprising an amatoxin, a target-binding moiety wherein the target is CD20, i.e., a CD20-binding moiety, and optionally a linker linking said amatoxin and said CD20-binding moiety. The invention further relates to the synthesis of said conjugate. In addition, the invention relates to a pharmaceutical composition comprising such conjugate, particularly for use in the treatment of B-cell and/or lymphoma associated diseases and/or malignancies.

Provided herein are antibody conjugates with binding specificity for CD74 and compositions comprising the antibody conjugates, including pharmaceutical compositions, methods of producing the conjugates, and methods of using the conjugates and compositions for therapy.

The present invention relates to linkers having a group of propiolyl, substituted acryl (acryloyl), or disubstituted propanoyl, and using such linkers for the conjugation of compounds, in particular, cytotoxic agents to a cell-binding molecule.

The present application relates to conjugates comprising an amatoxin a target-binding moiety wherein the target is CD37, i.e., a CD37-binding moiety, and optionally a linker linking said amatoxin and said CD37-binding moiety. The invention further relates to the synthesis of said conjugates. In addition, the invention relates to a pharmaceutical composition comprising such conjugate for use in the treatment of immune cell-, particularly B-cell and/or lymphoma associated diseases and/or malignancies.

Disclosed are methods and compositions relating to the treatment of autoimmune diseases using anti-CD45 antibody drug conjugates (ADCs).

The invention provides methods of using allogeneic cells in therapy by combining allogeneic cell therapy with anti-CD137 antibody drug conjugates (ADCs). Disclosed are methods of treating or preventing a host versus graft (HvG) rejection in a human subject receiving allogeneic cell therapy by administering to the human subject an anti-CD137 ADC.
