Provided are compositions for activating NK cells to stimulate an immune response for treating cancer and other disorders. In one embodiment, the invention provides a compound comprising an NK engaging domain that binds to CD 16; an NK activating domain operably linked to the NK engaging domain; and a targeting domain that selectively binds to a target cell and is operably linked to the NK activating domain and the NK engaging domain, wherein the targeting domain binds to CLEC12A.

NK engager molecules and methods of use thereof

An anti-canine CD16 polypeptide generally includes a CDR region of SEQ ID NO:5, a CDR region of SEQ ID NO:9, or a functional variant of either CDR region. An anti-canine CD64 polypeptide generally includes a CDR region of SEQ ID NO:13, a CDR region of SEQ ID NO:17, or a functional variant of either CDR region. The anti-canine CD16 polypeptide and anti-canine CD64 polypeptide may be incorporated into a therapeutic compound, a multispecific compound, a targeted imaging compound, or a capture assay device.

Anti-canine CD16 polypeptides, anti-canine CD64 polypeptides, compositions including same, and methods of using

This disclosure provides a bispecific ligand directed toxin (BLT) that includes a diphtheria toxin (DT) molecule that has been mutated to create a DT molecule that induces less of an immune response than native diphtheria toxin. The deimmunized DT molecule is fused with targeting ligands to create a fusion protein that can selectively deliver the deimmunized DT to target cells to kill the target cells.

Deimmunized therapeutic compositions and methods

Disclosed herein are a monoclonal antibody that specifically binds to human CD133 and single-chain variable fragments thereof. Also disclosed herein is a hybridoma that produces the monoclonal antibody that specifically binds to human CD133.

Single-chain variable fragment anti-CD133 antibodies and uses thereof

This disclosure describes engineered compounds that engage NK cells and methods of using the compounds. Generally, the compound includes an NK engaging domain, a targeting domain that selectively binds to a target cell, and an NK activating domain operably linking the NK engaging domain and the targeting domain.

Therapeutic compounds and methods

Methods and composition involving genetically engineered targeting conjugates with reversed orientation of VL and VH chains are provided. For example, in certain aspects targeting conjugates comprising VL and VH chains of anti-CD22 and anti-CD19 are described. In a further aspect, the invention provides methods and targeting conjugates comprising therapeutic agents or diagnostic agents for delivery to B cells.

Methods and compositions for bi-specific targeting of CD19/CD22

Disclosed herein are a monoclonal antibody that specifically binds to human CD 133 and single-chain variable fragments thereof. Also disclosed herein is a hybridoma that produces the monoclonal antibody that specifically binds to human CD133.

Single chain variable fragment anti-CD133 antibodies and uses thereof

The present disclosure features, inter alia, receptor-targeting reagents (e.g., immunotoxic receptor-targeting reagents), methods of binding a receptor-targeting reagent to a cell and methods for treating a variety of disorders. Also featured are methods, compositions, and kits for selecting an appropriate treatment modality for a subject and/or treating a variety of disorders.

Receptor-targeting reagents containing epidermal factor receptor-binding agents and IL-13 receptor-binding agents or IL-4 receptor-binding agents

The invention features vectors encoding immunotoxic fusion proteins containing targeting domains and toxic domains, targeting cells transduced with the vectors, methods of making the targeting cells, and methods of treating diseases (e.g., cancer) using both the vectors and the transduced cells.

Cell-mediated targeting of toxins to pathogenic cells

The invention provides fusion toxins that contain one or more regions of diphtheria toxin and a portion of urokinase-type plasminogen activator, as well as the nucleic acids that encode the fusion toxins and methods of using the fusion toxins.

DTAT fusion toxin

The invention features fusion protein monomers, multimeric immunotoxic proteins, nucleic acids encoding fusion protein monomers, vectors containing the nucleic acids, and cells containing the vectors. Also encompassed by the invention are methods of killing pathogenic cells and making multimeric immunotoxic proteins.

Multimeric immunotoxins

The present invention provides the synthesis and purification of a new class of compounds known as radiolabeled fusion toxins (RFT), in which both toxin and radionuclide tags are contained on the same growth factor, for example, murine granulocyte macrophage colony stimulating factor, mGM-CSF, epidermal growth factor, or murine interleukin-4, mIL-4.

Radiolabeled fusion toxins for cancer therapy

Radioimmunotoxins consisting of a monoclonal antibody covalently coupled to a toxin and a radionuclide. The compositions retain high binding specificity and cytotoxic activity and are useful in treating cancer and in bone marrow transplantation. The antibody component determines the selectivity. The toxin component kills the targeted cells. The radionuclide component also kills, but by a different mechanism, thus ensuring the eradication of all tumor cells. The radionuclide also allows the radioimmunotoxin to be tracked in vivo which enables the determination of its distribution throughout the body. Also, the pharmacokinetics of injected radioimmunotoxin can be determined allowing for more exact dose quantitation and administration.
