This invention relates to a Kit formulation to prepare a radioactive, bone-seeking, pharmaceutical drug that has high radiochemical purity (RCP) in a fast, facile and reproducible process. The Kit has at least two vials and a two-part buffer system with instructions on how to make the drug formulation in a radiopharmacy. The drug formulations of this invention can be conveniently and reproducibly prepared with better delivery of the drug to mammals, better radiochemical purity of the formulation for use in treating a mammal having bone pain, one or more calcific tumors or needing bone marrow suppression or bone marrow ablation.

Provided is a composition containing a buffer to be used at the time of labeling of a chelated targeting agent with .sup.90Y, .sup.153Sm, .sup.165Dy, .sup.165Er, .sup.166Ho, or .sup.177Lu. At least one kind of buffer selected from the group consisting of benzoic acid, maleic acid, fumaric acid, succinic acid, and salts thereof is incorporated in a composition containing a chelated targeting agent.

A method of preparing a .sup.64Cu-BaBaSar-RGD.sub.2 solution is provided. The method includes lyophilizing a solution of BaBaSar-RGD.sub.2 and adding a .sup.64Cu solution to the lyophilized BaBaSar-RGD.sub.2.

Provided is a composition containing a buffer to be used at the time of labeling of a chelated targeting agent with .sup.90Y, .sup.153Sm, .sup.165Dy, .sup.165Er, .sup.166Ho, or .sup.177Lu. At least one kind of buffer selected from the group consisting of benzoic acid, maleic acid, fumaric acid, succinic acid, and salts thereof is incorporated in a composition containing a chelated targeting agent.

In the present disclosure, embodiments of dual-stage syringes are disclosed along with delivery systems incorporating the dual-stage syringes. Embodiments of the dual-stage syringes described herein include sleeved dual-stage syringes, turn-key dual-stage syringes and dual-stage syringes including one or more one-way valves.

Provided is a composition containing a buffer to be used at the time of labeling of a chelated targeting agent with .sup.90Y, .sup.153Sm, .sup.165Dy, .sup.165Er, .sup.166Ho, or .sup.177Lu. At least one kind of buffer selected from the group consisting of benzoic acid, maleic acid, fumaric acid, succinic acid, and salts thereof is incorporated in a composition containing a chelated targeting agent.

In the present disclosure, embodiments include flaring tip microcatheters, methods of deploying flaring tip microcatheters, and embolization treatment methods. The flaring tip microcatheter may include a hollow shaft having a shaft lumen defined therein, a core disposed within the shaft lumen, and a tip including at least two petals affixed to a distal end of the core, the at least two petals including at least two wires wherein the core is hollow and defines a core lumen. The at least two wires may be configured to pull the at least two petals to form a flared configuration of the tip. The flared configuration of the tip may allow for laminar flow of a therapeutic agent distally from the tip.

Hereby, we disclose and claim, the concept, designs, enabling technologies, and utility for therapy of patients suffering from cancer, of a novel class of biomolecularly engineered, synthetic molecules: antibody-vaccine engineered constructs (AVEC). They comprise the main functional domains (antibodies and vaccines) and the supporting domains (linkers and reporters). Their mechanisms of actions rely upon antibody dependent redirecting, accelerating, and amplifying of the prophylactic or natural vaccination induced immune response (ADRAAVIR) from the initially elicited by vaccination towards the finally aimed by therapies. The routes of administration to the patients, pharmacokinetics, pharmacodynamics, pharmacogenomics, and therapeutic efficacies are resultant of those of the pertinent antibodies and vaccines assembled within AVEC.

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.
