The present invention relates to the field of radiopharmaceuticals for in vivo imaging, in particular to a method of purifying a radiotracer which comprises .sup.18F-labelled aminoxy-functionalised biological targeting moiety. The invention provides radioprotectant-containing radiopharmaceutical compositions of the tracers, as well as associated automated methods and cassettes.

Ligands that are based on the pyclen macrocycle that are reinforced, which are useful for complexing elements such as radioelements and/or elements with magnetic properties.

The present disclosure relates to the synthesis of radionuclide complex solutions, in particular for their use in the commercial production of radioactive drug substances, for diagnostic and/or therapeutic purposes. In particular, the synthesis method comprises the following steps in the following order: a. providing a radionuclide precursor solution into a first vial, b. transferring the radionuclide precursor solution into a reactor, c. providing a reaction buffer solution into said first vial containing residual radionuclide precursor solution, d. transferring the buffer reaction solution and residual radionuclide precursor solution from said first vial into the reactor, e. transferring a peptide solution comprising the somatostatin receptor binding peptide linked to a chelating agent, into the reactor, f. reacting the somatostatin receptor binding peptide linked to a chelating agent with said radionuclide in the reactor to obtain the radionuclide complex, g. recovering said radionuclide complex.

The present disclosure relates to a solution comprising a water insoluble carbohydrate and a fluorescent dye, such as a near infrared (NIR) contrast agent, wherein the solution sets under aqueous conditions, such as in vivo, to form e.g. a gel, a glass, a semi-solid, a solid, a crystal or any mixtures thereof. The disclosure further relates to preparation of such solution and use of such solution for in vivo imaging and/or guidance of surgery or interventional therapeutic procedures.

The present invention relates to a somatostatin analogue composition for radiopharmaceutical use, in particular for diagnostic or therapeutic use. More specifically the somatostatin analogue is a receptor-selective somatostatin peptide antagonist.

The present invention is directed to radiopharmaceuticals with improved stability, a kit, and a method of production thereof.

The disclosure provide an apparatus for producing a nuclide by using a liquid target which can perform the nuclear reaction process and can discharge the radioactive gas such as Radon within the vial. As described above, an apparatus for producing a nuclide by using a liquid target according to the present disclosure can minimize quantitative loss of a reactant by performing the nuclear reaction process using a target of a liquefied state and reusing a liquefied target on which the nuclear reaction process has not been performed, and can improve safety by enabling the radioactive gas generated to be disposed.

This invention relates new radiopharmaceutical conjugates for use in improved methods of diagnosis and treatment of cancer. The radiopharmaceutical conjugate comprises, in sequence: a metabolite that targets tumour cells, bound to a chelating agent capable of containing a radionuclide, bound to a linker capable of binding with an EPR agent in vitro or in vivo; or a chelating agent capable of containing a radionuclide, bound to a metabolite that targets tumour cells, bound to a linker capable of binding with an EPR agent in vitro or in vivo. The radiopharmaceutical conjugates of the present invention provide active and passive targeted radio nuclide delivery systems that can help to improve the biodistribution and pharmacological toxicity of the radiopharmaceuticals used for the diagnosis and therapy of cancer.
