Antigen binding constructs that bind to CD4, for example antibodies, including antibody fragments (such as scFv, minibodies, and cys-diabodies) that bind to CD4, are described herein. Methods of use are described herein.

The RI-labeled anti-MUC5AC humanized antibody of the present invention is a conjugate of a chelating agent chelated with a radionuclide and an antibody (the radionuclide is a metal nuclide that emits α particle or positron, and the antibody is a humanized antibody specifically binding to MUC5AC), and is superior in specificity for MUC5AC and accumulation in tumor. Therefore, it is extremely useful for the treatment and/or diagnosis of diseases in which MUC5AC is overexpressed, particularly cancer.

This invention provides a method for treating a subject afflicted with cancer, comprising administering to the subject (i) a BCL-2 inhibitor in conjunction with (ii) an alpha-emitting isotope-labeled agent that targets cancer cells in the subject, wherein the amounts of the BCL-2 inhibitor and labeled agent, when administered in conjunction with one another, are therapeutically effective. This invention also provides a method for inducing the death of a cancer cell, comprising contacting the cell with (i) a BCL-2 inhibitor in conjunction with (ii) an alpha-emitting isotope-labeled agent that targets the cancer cell, wherein the amounts of BCL-2 inhibitor and labeled agent, when concurrently contacted with the cell, are effective to induce the cell's death.

Radiolabeled anti-PD-L1 antibodies and their use in immuno-PET imaging are provided herein. Included are methods of detecting the presence of PD-L1 proteins in a patient or sample.

Provided herein are methods for iodinating biomolecules, including proteins and peptides. The methods can be used to successfully and efficiently iodinate biomolecules under relatively mild reaction conditions. As a consequence, the methods described herein can be used to iodinate biomolecules that include, for example, an oxidatively unstable moiety (e.g., an optical dye) without adversely impacting the oxidatively unstable moiety.

Compounds containing TRPV6-binding peptides and their use in the detection and diagnosis of cancer are described. Also described are methods for detecting and staging cancer that use the compounds of the invention. Compounds containing TRPV6-binding peptides are useful for the delivery of diagnostic and therapeutic agents to cells or tumors that express TRPV6.

Combination therapies comprising administering radioimmunoconjugates and one or more checkpoint inhibitors.

The present disclosure provides ex vivo armed T cell (EAT) compositions that comprise multi-specific (e.g., bispecific) antibodies that bind to CDS and at least one additional target antigen (e.g., antigen that is expressed by tumor cells and/or a DOTA label). The EAT compositions of the present technology are useful for adoptive immunotherapy in a subject in need thereof.

Among the various aspects of the present disclosure is the provision of compositions of isotope-ligand complexes, methods of use thereof, and methods of chelating isotopes. The present disclosure also provides for methods for modulating ion channel transportation of radiopharmaceuticals. For example, the inhibition of radiopharmaceutical transport comprises administering an ion channel transport modulating or inhibiting agent (e.g., a calcium channel inhibitor) in an amount effective to inhibit gastrointestinal uptake.

The present invention provides various PRAME binding molecules (including antibodies, antibody fragments, chimeric antigen receptors, and the like), compositions and cells (including T cells) comprising such PRAME binding molecules, and methods of using such PRAME binding molecules, compositions and cells, for example in the detection and/or monitoring of PRAME-positive tumors.
