The present invention relates to stable pharmaceutical compositions of sulfur colloid, which advantageously provide a high radiochemical purity to .sup.99mTc-pertechnetate without causing the gel formation. The compositions include pre-lyophilized and lyophilized compositions of sulfur colloid. It also relates to a non-radioactive kit which upon reconstitution with .sup.99mTc-pertechnetate solution gives stabilized .sup.99mmTc-Sulfur colloid radiopharmaceutical composition. Further, the process for preparation of said compositions and their use for diagnostic purposes are also disclosed.

The present disclosure relates to gastrin-releasing peptide receptor (GRPR) targeting radiopharmaceuticals and uses thereof. In particular, the present disclosure relates to a pharmaceutical composition comprising radiolabeled GRPR-antagonist and a surfactant. The present disclosure also relates to radiolabeled GRPR-antagonist for use in treating or preventing a cancer.

A method for in vivo location determination of a balloon catheter according to an embodiment of the present disclosure includes inserting into a body of a subject a balloon catheter including a balloon inflated by a balloon inflation composition including a radioactive isotope as an active ingredient; and detecting the in vivo location of the radioactive isotope. The balloon inflation composition for in vivo location determination of a balloon catheter allows accurate and safe determination of the location of the balloon catheter inserted into the body from outside the body.

A system for in vivo location determination of a balloon catheter according to an embodiment of the present disclosure includes a detector configured to detect proximity of a radioactive material, a guide wire provided to be inserted into a body, an intermediate member which has a radioactive material detected by the detector, and is configured to be inserted into the body along the guide wire to set an insertion length at which the radioactive material is detected by the detector, and a balloon catheter which is inserted into the body along the guide wire, and is inserted into the body by the set insertion length.

Despite the widespread use of nanotechnology in radio-imaging applications, lipoprotein based delivery systems received only limited attention so far. The subject application provides for the synthesis of a novel hydrophobic radio-imaging tracer. This tracer, comprising a hydrazinonicotinic acid (HYNIC)-N-dodecylamide and .sup.99mTc conjugate can be encapsulated into rHDL nanoparticles (NPs). These rHDL NPs can selectively target the Scavenger Receptor type B1 (SR-B1) that is overexpressed on most cancer cells due to excess demand for cholesterol for membrane biogenesis and thus can target tumors in-vivo. Details of the tracer synthesis, characterization of rHDL/tracer complex, in-vitro uptake, stability studies and in-vivo application of this new radio-imaging approach are provided.

The present invention provides amphiphilic telodendrimers that aggregate to form nanocarriers characterized by a hydrophobic core and a hydrophilic exterior. The nanocarrier core may include amphiphilic functionality such as cholic acid or cholic acid derivatives, and the exterior may include branched or linear poly(ethylene glycol) segments. Nanocarrier cargo such as hydrophobic drugs and other materials may be sequester in the core via non-covalent means or may be covalently bound to the telodendrimer building blocks. Telodendrimer structure may be tailored to alter loading properties, interactions with materials such as biological membranes, and other characteristics.

A method of reducing radiation exposure of a non-cancerous tissue of a patient diagnosed with a cancer includes administering to the patient an agent capable of competing for binding sites on a surface of the non-cancerous tissue, provided that the administration is carried out after a waiting period that follows administration of a compound including a radionuclide to the patient, the compound having affinity for both a cancerous tissue and the non-cancerous tissue, and, further provided that the binding sites have an affinity for both the agent and the compound.

The invention described herein pertains to folate-receptor targeted agents comprising therapeutic agents useful for the treatment of inflammatory disease, including folate-receptor targeted liposomes (folate-targeted liposomes) containing entrapped therapeutic agents and folate-receptor targeted dendrimers conjugated to therapeutic agents (folate-targeted dendrimer conjugates), useful for the treatment of inflammatory disease, including auto-immune disease, as well as to folate-targeted liposomes containing entrapped imaging agents and dendrimer conjugates conjugated to imaging agents, for use in the diagnosis and monitoring of treatment in such disease.

A method for the prognosis of response to treatment for a patient suffering from cancer, the method comprising: measuring the expression of at least one immune marker in a leukocyte sample taken from the patient with cancer; classifying the patient sample into (i) sustainable responders (SR) to selective internal radiation therapy (SIRT) or (ii) transient/non-responders (TR/NR) to (SIRT) based on expression of the at least one immune marker in relation to a predetermined value and treating sustainable responders (SR) to SIRT or SIRT or a composition comprising SIRT and an immunotherapy. In a preferred embodiment, the method is for the prognosis of response to treatment of a Hepatocellular carcinoma (HCC) patient comprising detecting the co-expression of PD-1 or Tim-3 with CCR5; or expression of PD-1, Tim-3, CXCR6, or combinations thereof in a leukocyte sample taken from the patient.
