Patent number: 9919059Abstract: Nanoparticles for a selective, two stage delivery to tumors have been developed. The nanoparticles are initially sized so that they preferentially accumulate in the tumor tissue as a result of leakage through the defective vascular in the solid tumors. Once in the tumor tissue, the nanoparticles are cleaved hydrolytically and/or by enzymatic cleavage over time to release smaller nanoparticles carrying therapeutic, prophylactic or diagnostic agents into the necrotic interior of the tumors. This provides a simple, elegant and highly effective means of delivery drug selectively not just to tumors generally, but, more importantly, into the poorly vascularized necrotic interiors which drugs are normally unable to penetrate. The nanoparticles have a number of advantages: less toxicity due to selective accumulation only in the tumors; access into the poorly vascularized necrotic interiors of the tumor; and sustained release over a period of time within the tumor.Type: GrantFiled: December 10, 2013Date of Patent: March 20, 2018Assignees: Massachusetts Institute of Technology, The General Hospital CorporationInventors: Cliff R. Wong, Moungi G. Bawendi, Dai Fukumura, Rakesh K. Jain

Patent number: 9629923Abstract: A CDDP complex is formed by complexation of CDDP and a polymer having a structure of Formula (I). The CDDP complex has good biocompatibility and is degradable. A side chain of the polymer is grafted with polyethylene glycol, which gives the CDDP complex good dissolvability. When dissolved in an aqueous medium, the CDDP is protected by a hydrophilic polyethylene glycol chain segment and a hydrophobic amino acid chain segment, which can effectively avoid a sudden release of the CDDP due to the influence of the blood circulation system after intravenous injection, thus improving the stability of the CDDP complex. A carboxyl group contained in the CDDP complex has pH value sensitivity and tends to be deprotonated in a low pH environment, which is advantageous for promoting the release of a drug, and improving the efficiency of the drug.Type: GrantFiled: March 26, 2013Date of Patent: April 25, 2017Assignee: Changchun Institute of Applied Chemistry, Chinese Academy of ScienceInventors: Zhaohui Tang, Haiyang Yu, Wantong Song, Mingqiang Li, Xiuli Zuang, Xuesi Chen

Patent number: 9028800Abstract: The present application discloses compositions and methods of synthesis and use of 18F or 19F-labeled molecules of use in PET, SPECT and/or MR imaging. Preferably, the 18F or 19F is conjugated to a targeting molecule by formation of a complex with a group IIIA metal and binding of the complex to a bifunctional chelating agent, which may be directly or indirectly attached to the targeting molecule. In other embodiments, the 18F or 19F labeled moiety may comprise a targetable construct used in combination with a bispecific antibody to target a disease-associated antigen. The disclosed methods and compositions allow the simple and reproducible labeling of molecules at very high efficiency and specific activity in 30 minutes or less. In preferred embodiments, the labeled molecule may be used for imaging in a subject without purification after labeling.Type: GrantFiled: May 8, 2014Date of Patent: May 12, 2015Assignee: Immunomedics, Inc.Inventors: Christopher A. D'Souza, William J. McBride, David M. Goldenberg

Publication number: 20150125388Abstract: The invention relates to novel multi-modality probes for imaging, tracking and analyzing stem cells and related biological samples, and methods of preparation and use thereof. The molecular probes of the invention are constructed, for example, by utilizing (a) the high selectivity of long hydrocarbon chains for binding to plasma membranes of cells, (b) a near-infrared (NIR) dye for optical imaging, and (c) a radionuclide for PET or SPECT imaging. The in vitro and in vivo data of the optical and radiolabeled probes demonstrated their utility for detecting the presence of stem cells with multiple imaging modalities.Type: ApplicationFiled: May 27, 2013Publication date: May 7, 2015Applicant: Vniversity of Massachusetts Medical SchoolInventors: Brian D. Gray, Mary Rusckowski, Koon Y. Pak
