Abstract: The present invention relates to compositions and methods of formulating nanoparticle drugs for cancer treatment in particular for intravenous administration in particular nanoparticle formulations containing cytotoxic drugs for the treatment of cancer. The compositions may have properties which facilitate the release of drugs into the patient including being unstable in plasma/blood, having low AUC, low Cmax, high Vd, CMC above theoretical Cmax of the drug, high tumor/plasma AUC. The present invention also provides for methods of administration and compositions which are unstable after administration to a patient so that the cytotoxic drug may bind to endogenous proteins such as albumin and be delivered to tumors in the patient.

Abstract: The invention provides multiparametric anti-SPARC antibody-based techniques for treating cancers as well as determining prognosis and predicting the response to therapy, including chemotherapy, radiotherapy, surgical therapy and combination therapies.

Abstract: The invention relates to nucleic acid aptamers having the ability to bind human SPARC protein (osteonectin) with specificity. The invention also relates to compositions including such aptamers, as well as methods of identifying such aptamers. The invention further relates to methods for using such aptamers in treating and diagnosing proliferative diseases such as, e.g., cancer.

Abstract: The invention provides methods of treating a mammal afflicted with an inflammatory disease, such as peritonitis, peritoneal adhesions or endometriosis, comprising the administration, intraperitoneal or otherwise, of a therapeutically effective amount of a SPARC polypeptide or a SPARC polypeptide-encoding isolated polynucleotide and a pharmacologic carrier.
