Abstract: Described herein is a chelator for radiolabels (e.g., 89Zr) for targeted PET imaging that is an alternative to DFO. In certain embodiments, the chelator for 89Zr is the ligand, 3,4,3-(LI-1,2-HOPO) (“HOPO”), which exhibits equal or superior stability compared to DFO in chemical and biological assays across a period of several days in vivo. As shown in FIG. 1, the HOPO is an octadentate chelator that stabilizes chelation of radiolabels (e.g., 89Zr). A bifunctional ligand comprising p-SCN-Bn-HOPO is shown in FIG. 4 and FIG. 5. Such a bifunctional ligand can eliminate (e.g., 89Zr) loss from the chelate in vivo and reduce uptake in bone and non-target tissue. Therefore, the bifunctional HOPO ligand can facilitate safer and improved PET imaging with radiolabeled antibodies.

Abstract: The present invention provides a fluorescent silica-based nanoparticle that allows for precise detection, characterization, monitoring and treatment of a disease such as cancer. The nanoparticle has a range of diameters including between about 0.1 nm and about 100 nm, between about 0.5 nm and about 50 nm, between about 1 nm and about 25 nm, between about 1 nm and about 15 nm, or between about 1 nm and about 8 nm. The nanoparticle has a fluorescent compound positioned within the nanoparticle, and has greater brightness and fluorescent quantum yield than the free fluorescent compound. The nanoparticle also exhibits high biostability and biocompatibility. To facilitate efficient urinary excretion of the nanoparticle, it may be coated with an organic polymer, such as poly(ethylene glycol) (PEG). The small size of the nanoparticle, the silica base and the organic polymer coating minimizes the toxicity of the nanoparticle when administered in vivo.

Abstract: Presented herein are methods and compositions for non-invasive imaging of TAMs with discoidal high-density lipoproteins to assess prognosis and therapy outcome. TAMs are increasingly investigated in cancer immunology, and are considered a promising target for better and tailored treatment of malignant growths. Although TAMs also have high diagnostic and prognostic value, TAM imaging still remains largely unexplored. Imaging agents/methods provided herein are of value for non-invasive in vivo evaluation of TAM burden, not only in preclinical but also in clinical settings.

Abstract: Described herein is a non-invasive quantitative positron emission tomography (PET) nanoreporter technology that allows personalized therapeutic outcome prediction. In a breast cancer mouse model, it was demonstrated that co-injecting Doxil and a Zirconium-89 nanoreporter (89Zr-NRep) enabled highly precise doxorubicin (DOX) quantification. Imaging 89Zr-NRep via PET revealed remarkable Doxil accumulation heterogeneity independent of tumor size.

Abstract: The invention concerns various methods of using labeled HSP90 inhibitors to improve treatment of cancer patients with HSP90 inhibitors, including ex vivo and in vivo methods for determining whether a tumor will likely respond to therapy with an HSP90 inhibitor. The disclosure provides a method for determining whether a tumor will likely respond to therapy with an HSP90 inhibitor which comprises the following steps: (a) contacting the tumor or a sample containing cells from the tumor with a detectably labeled HSP90 inhibitor which binds preferentially to a tumor-specific form of HSP90; (b) measuring the amount of labeled HSP90 inhibitor bound to the tumor or the tumor cells in the sample; and (c) comparing the amount of labeled HSP90 inhibitor bound to the tumor or the tumor cells in the sample measured in step (b) to the amount of labeled-HSP90 inhibitor bound to a reference.

Abstract: A packaging system includes a stacking apparatus which utilizes a supplemental stacking member on a transfer mechanism for receiving at least one article from a conveying mechanism while the transfer mechanism is transferring a stack, such that a new stack is begun prior to completing the transfer of the first stack. This permits a substantially constant supply of articles to be provided continuously to the stacking apparatus without having to interrupt or slow down the flow of articles to the apparatus. The packaging system also includes a boxing apparatus which relies on pneumatically-actuated positioning mechanisms to move stacks of articles to discrete positions within boxes. Both the position and the velocity of the pneumatic mechanisms are utilized as feedback to provide increased speed without compromising positioning accuracy.
