The present invention provides compositions for targeting SAS1B positive cancer cells using immunotoxin technology and discloses that kidney and pancreatic cancer cells are SAS1B positive, but not normal kidney and pancreatic cells. The invention discloses that despite being expressed only in growing oocytes in females among normal tissues SAS1B is expressed in cancers of both men and women.

This disclosure provides ASCT2-binding molecules, e.g., anti-ASCT2 antibodies, and antigen-binding fragments thereof. In certain aspects, the ASCT2-binding molecules are conjugated to cytotoxic drugs, e.g., ASCT2 antibody-drug conjugates (ADCs). In certain aspects, the anti-ASCT2 antibodies and fragments thereof can be hybridoma-derived murine monoclonal antibodies, and humanized versions thereof. In certain aspects, the ASCT2-binding molecules bind specifically to cells expressing ASCT2, and in some instances, are internalized into the cells. In addition, this disclosure provides compositions and methods for diagnosing and treating diseases or disorders characterized by ASCT2 overexpression, e.g., certain types of cancer. In a particular embodiment, the disclosure provides methods for treating cancer using ASCT2 ADCs.

It is an object of the present invention to provide a medicament for killing tumor cells, having few side effects. According to the present invention, provided is a medicament for killing tumor cells, comprising: a conjugate of a substance that binds to a target substance on the surface of tumor cells and a cytotoxin; and a glycosylated chlorin derivative or a pharmaceutically acceptable salt thereof.

The present invention concerns methods of diagnosing and treating a malignant neoplasm of the CNS by detecting mammalian tissue expressing integrin alpha 10 subunit or a fragment or variant thereof, and administering a drug specific for integrin alpha 10 subunit.

The present disclosure provides anti-CD73 binding molecules, e.g., antibodies and antigen binding fragments thereof. Also provided are pharmaceutical formulations comprising the disclosed compositions, and methods for the diagnosis and treatment of diseases associated with CD73-expression, e.g., cancer. Such diseases can be treated, e.g., by direct therapy with the anti-CD73 binding molecules disclosed herein (e.g., naked antibodies or antibody-drug conjugates that bind CD73), by adjuvant therapy with other antigen-binding anticancer agents such as immune checkpoint inhibitors (e.g., anti-CTLA-4 and anti-PD-1 monoclonal antibodies), and/or by combination therapies where the anti-CD73 molecules are administered before, after, or concurrently with chemotherapy.

Novel modulators, including antibodies and derivatives thereof, and methods of using such modulators to treat hyperproliferative disorders are provided.

Novel modulators, including antibodies and derivatives thereof, and methods of using such modulators to treat proliferative disorders are provided.

The present disclosure provides anti-CD73 binding molecules, e.g., antibodies and antigen binding fragments thereof. Also provided are pharmaceutical formulations comprising the disclosed compositions, and methods for the diagnosis and treatment of diseases associated with CD73-expression, e.g., cancer. Such diseases can be treated, e.g., by direct therapy with the anti-CD73 binding molecules disclosed herein (e.g., naked antibodies or antibody-drug conjugates that bind CD73), by adjuvant therapy with other antigen-binding anticancer agents such as immune checkpoint inhibitors (e.g., anti-CTLA-4 and anti-PD-1 monoclonal antibodies), and/or by combination therapies where the anti-CD73 molecules are administered before, after, or concurrently with chemotherapy.

Disclosed herein are non-myeloablative antibody-toxin conjugates and compositions that target cell surface markers, such as the CD34, CD45 or CD117 receptors, and related methods of their use to effectively conditioning a subject's tissues (e.g., bone marrow tissue) prior to engraftment or transplant. The compositions and methods disclosed herein may be used to condition a subject's tissues in advance of, for example, hematopoietic stem cell transplant and advantageously such compositions and methods do not cause the toxicities that are commonly associated with traditional conditioning methods.

The invention provides therapeutic humanized anti-HERV-K antibodies, CAR, or a fusion thereof consisting of a bispecific T cell engager (BiTE) FOR CD3 and CDS, a DNA-encoded BiTE (DBiTE), or an antibody-drug conjugate (ADC). The invention also relates to peptides, proteins, nucleic acids, and cells for use in immunotherapeutic methods. In particular, the invention relates to the immunotherapy of cancer peptides bound to molecules of the MHC, or peptides as such, which can also be targets of antibodies and other binding molecules.
