Methods for treating a proliferative disease in hematologic malignancy in a subject having a complex karyotype by administering an effective amount of an immunotherapy which includes a targeting agent for an epitope of CD33. The proliferative disease may be a hematological disease or disorder such as multiple myeloma, acute myeloid leukemia, myelodysplastic syndrome, and myeloproliferative neoplasm. The effective amount of the anti-CD33 targeting agent may be an amount sufficient to induce myeloconditioning or an amount to induce myeloablation. The methods may further include transplanting allogeneic stem cells to the patient after administration of the anti-CD33 targeting agent.

A patient specific therapeutic composition provided in a single dose container, the total volume of which may be administered to a patient in a single treatment session. The composition includes a monoclonal antibody having a labeled fraction and an unlabeled fraction, and a pharmaceutically acceptable carrier. The label may be any of a radioisotope or a drug such as a chemotherapeutic or cytotoxic agent. The amount of the monoclonal antibody and any conjugated label molecule may depend on at least one patient specific parameter selected from a patient weight, a patient age, a patient height, a patient gender, a patient medical condition, and a patient medical history. Methods of administration, production, and articles of manufacture comprising the patient specific therapeutic composition are also disclosed.

The present invention is directed to a method for the preparation of a radiolabled conjugate composition comprising Bismuth-213 loaded targeting moieties that have been diluted with cold targeting moieties in a predetermined ratio of amount of cold targeting moieties to amount of Bismuth-213 loaded targeting moieties. Said ratio is determined by determining the amount T of target moieties per diseased cell to be treated, and determining the amount Z of Bismuth-213 atoms needed to kill a diseased cell, and contacting targeting moieties with Bismuth-213 atoms in a ratio of T over Z, to form a conjugate composition with a predetermined ratio of cold targeting moieties and Bismuth-213 loaded targeting moieties. The invention is further directed to a conjugate that can be prepared with the method according to the invention, a pharmaceutical formulation comprising the conjugate according to the invention.

Disclosed is a non-invasive PET-CT imaging method for detecting acute myeloid leukemia (AML) or extramedullary disease (EMD) in a subject using a radioactive isotope-labeled anti-CD33 antibody. Also disclosed is a PET-CT imaged-guided method for treating AML or EMD.

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.

Compositions and methods are described for stabilizing a radio-iodinated monoclonal IgG antibody for up to 17 days against radiolytic decomposition. The stabilized radiolabeled murine antibody binding the CD45 antigen expressed on various forms of lymphomas is useful as a radio-therapeutic and diagnostic agent in the treatment of human malignancies of hematopoietic origin, including lymphomas.

This invention provides a method for treating a subject afflicted with a hematologic malignancy comprising administering to the subject an agent targeting a hematologic malignancy-associated antigen, wherein the subject has a low peripheral cancerous cell burden. This invention also provides a method for treating a subject afflicted with a hematologic malignancy and having a high peripheral cancerous cell burden, comprising (i) medically lowering the subject's peripheral cancerous cell burden, and (ii) while the subject's peripheral cancerous cell burden is still low, administering to the subject an agent targeting a hematologic malignancy-associated antigen. Particularly envisioned are the subject methods for treating acute myeloid leukemia using an anti-CD33 antibody labeled with an alpha-emitting isotope, such as .sup.225Ac-HuM195.

Provided are humanized anti-human CD45 antibodies and pharmaceutical compositions including the antibodies.

The invention provides anti-CLL-1 antibodies and immunoconjugates and methods of using the same.
