    摘要: Compositions and methods for transient immunodepletion of specific subsets of a subject's immune cells are disclosed. The methods generally include administering to the subject an effective amount of a radiolabeled antibody against CD19, CD20, CD33, CD38, CD45RA, CD52, or a combination thereof. The effective amount of the radiolabeled antibody depletes at least 50% of the targeted immune cells, and less than 20% of the subject's stem cells. When used alone, these methods may target lymphomas, leukemias, and myelomas, and/or may additionally allow repopulation of non-autoreactive immune cells in patients with an autoimmune disease. When these methods precede certain cell-based therapies, such as adoptive cell therapy and/or hematopoietic stem cell therapy, the methods are able to enhance the outcome of the cell-based therapies while minimizing adverse effects.

    摘要: 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.

    摘要: 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.

    摘要: The invention is directed to a method for the purification of Radium, in particular 226Ra, for target preparation for an essentially pure 225Ac production from available radioactive sources, using an extraction chromatography in order to separate chemically similar elements such as Ba, Sr, and Pb from the desired Ra; wherein said extraction chromatography has an extractant system on the basis of a crown ether. The invention is related to a method for recycling of 226Ra, for target preparation for 225Ac production from radium sources irradiated with accelerated protons (p,2n), after separation of the produced 225Ac. In this method a combination of the above extraction chromatography and a cation exchange chromatography is used. The obtained 226Ra is essentially free of the following chemical contaminants consisting of Ag, Al, As, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Sr, V, Zn, and Ba.

    摘要: The present invention refers to a method for producing a radium target for the production of radionuclides by means of accelerated protons, whereby at least one radium containing material out of an aqueous-organic solution or suspension of such a material is applied by means of a dispersing device on a surface in such a way that the dispersing device and the surface are moving relatively towards each other and that the solvent is removed substantially spontaneously. Further, the invention refers to a radium target that is created in such a way that it may exhibit an activity of up to 1.5 curie. The radium targets according to the present invention serve for the production of the radionuclide 225Ac, which may be used in nuclear medicine in the treatment of cancer, particularly in form of its daughter nuclide 213Bi.
