Abstract: Provided herein are proteins comprising a novel antigen binding domain. Said antigen binding domain, and proteins comprising it, are able to bind to osteosarcoma cells under physiological conditions. The antigen binding domain comprises an antibody light chain variable domain (VL) and an antibody heavy chain variable domain (VH), each comprising three complementarity determining regions (CDRs) flanked by human framework sequences. The human framework sequences reduces the risk of triggering unwanted immunogenic responses against the antigen binding domain. This may be especially important in a therapeutic setting wherein a drug is administered repeatedly to a human osteosarcoma patient.

Abstract: Novel chimeric antigen receptors (CARs) are provided. When the CARs herein are expressed on the surface of immune cells, such immune cells may be directed to osteosarcoma cells as demonstrated with our in vivo data. In a murine intraperitoneal model, the tumor growth was significantly delayed for T cells expressing a CAR comprising a scFv from TP1 or TP3 antibodies. Immune cells expressing the CARs herein display therapeutic effect in the form of decreased tumor volume in a murine model simulating metastatic osteosarcoma. Combined with the finding that stem cells from healthy bone marrow were not significantly affected by T cells expressing any of the CARs, this disclosure provides an attractive cell therapeutic alternative for treatment of osteosarcoma.

Abstract: The present invention relates to a radioimmunoconjugate that binds human CD37. Pharmaceutical compositions and uses thereof for the treatment of cancer and in particular B cell malignancies are aspects of the present invention.

Abstract: The invention provides a method for the treatment of soft tissue disease in a mammalian subject (preferably a human or canine subject), said method comprising administering to said subject a therapeutically effective quantity of a soft tissue targeting complex of thorium-227 and a complexing agent, wherein said quantity is such that an acceptably non-myelotoxic quantity of radium-223 is generated in vivo by nuclear decay of the administered thorium-227.

Abstract: A method of prophylaxis of a subject having or having had a soft tissue cancer, whereby to combat metastatic bone cancer therein, the method comprising administering to said subject a physiologically tolerable polyphosphonate and, parenterally, a prophylactically effective amount of a soluble radium-223 or -224 salt or complex. A kit comprising a first container containing a soluble radium-223 or -224 salt or complex and a second container containing at least one dose of a physiologically tolerable polyphosphonate is also provided.

Abstract: Processes for the preparation, prepared solutions, and the use of radium-223 for the treatment of calcified tumors, bone tumors, treatment of bones, bone surfaces and soft tissues is described.
