Provided herein are radiopharmaceutical compositions and uses thereof. The radiopharmaceutical compositions can comprise one or more stabilizing agents, an aqueous vehicle, and a conjugate that comprises a targeting ligand and a radionuclide bound to a metal chelator. The targeting ligand can be a small molecule compound or a peptide such as a monocyclic peptide. The targeting ligand can be configured to bind with a tumor target. The stabilizing agent can comprise a radiolysis stabilizer, a free metal chelator, and/or a pH stabilizer. Further provided herein are methods of preparing the radiopharmaceutical compositions and methods of treating cancer by administering the described radiopharmaceutical compositions.

A nuclear medicine infusion system (10) may be used to generate and infuse radioactive liquid into a patient undergoing a diagnostic imaging procedure. In some examples, the infusion system includes a frame (30) that carries a radioisotope generator (52) that generates radioactive eluate via elution. The frame may also carry a beta detector (58) and a gamma detector (60). The beta detector can be positioned to measure beta emissions emitted from the radioactive eluate supplied by the generator. The gamma detector can be positioned to measure gamma emissions emitted from a portion of the radioactive eluate to evaluate a safety of the radioactive eluate delivered by the infusion system.

A theragnostic method is here described for treating a subject affected by a neoplasia by administering in both the diagnostic and therapeutic steps the same radioisotope, which is a .sup.64Cu.sup.++ salt. Such method comprises a diagnostic step to select a subject, in which there is .sup.64Cu.sup.++ cellular uptake. In case there is no uptake, the treatment is not advisable. In case there is copper uptake from cancer lesions, this has a predictive value of response to treatment. If the subject is selected for the treatment, the method further comprises a step of treating cancer in said subject by administering a therapeutically effective amount of the same .sup.64Cu.sup.++ salt.

A targeted radiopharmaceutical of chemical Formula I, below, is disclosed wherein Q.sup.+3 is a

##STR00001## trivalent radioactive isotope ion; M is a proton (H+), an ammonium ion or an alkali metal ion; “g” is a number that is 1 to about 12; the boxed mAb MNPR-101 represents the chemically-bonded humanized mAb MNPR-101; and Y− is an optional anion present in an amount needed to balance the ionic charge. A pharmaceutical composition that comprises a theranostic effective amount of a Formula I targeted radiopharmaceutical dissolved or dispersed in a pharmaceutically acceptable diluent is also disclosed, as are a method for treating and/or diagnosing a mammalian host having a disease, disorder or condition characterized by undesired angiogenesis, tumor growth and/or tumor metastasis. A targeted pro-radiopharmaceutical construct similar to that of Formula I but without the radioisotope (Formula III) is also contemplated.

The present disclosure concerns radiopharmaceutical compositions of radioactive halogenated benzylguanidine (such as radioiodinated MIBG) or a pharmaceutically acceptable salt, hydrate, or solvate thereof. In a preferred embodiment, the composition has at least 97% of radiochemical purity for at least 4 days. Advantageously, the compositions of the present disclosure may be devoid of parabens, which are carcinogenic and yet are used in known radioactive MIBG compositions. The present disclosure also provides processes of preparing a radioactive halogenated benzylguanidine composition. The compositions of the present disclosure can be used in diagnosis and treatment of various diseases.
