Abstract
Particle-emitting radionuclides, e.g. Samarium-153, have been complexed with organic aminoalkylenephosphonic acids wherein the nitrogen and phosphorus are interconnected by an alkylene group or substituted alkylene group. These complexes have been found useful in compositions for the therapeutic treatment of calcific tumors in animals.
Claims26
A composition comprising (1) a complex which comprises Sm-153 and at least one of an aminophosphonic acid or a physiologically acceptable salt thereof wherein the aminophosphonic acid is selected from the group consisting of ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, hydroxyethylethylenediaminetrimethylenephosphonic acid, tris(2-aminoethyl)aminehexamethylenephosphonic acid, bis(aminoethyl)piperazinetetramethylenephosphonic acid, and (1-carboxy)ethylenediaminetetramethylenephosphonic acid and (2) at least one of the above aminophosphonic acids, or a physiologically acceptable salt thereof, in excess of that required to make the complex, and wherein the resulting composition is therapeutically effective.
A composition comprising (1) a complex which comprises Sm-153 and ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof and (2) ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof, in excess of that required to make the complex, and wherein the resulting composition is therapeutically effective.
A method for the therapeutic treatment of an animal having one or more calcific tumors which comprises administering to said animal a therapeutically effective amount of a composition comprising (1) a complex which comprises SM-153 and at least one of an aminophosphonic acid or a physiologically acceptable salt thereof wherein the aminophosphonic acid is selected from the group consisting of ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, hydroxyethylethylenediaminetrimethylenephosphonic acid, tris(2-aminoethyl)aminehexamethylenephosphonic acid, bis(aminoethyl)piperazinetetramethylenephosphonic acid, and (1-carboxy)ethylenediaminetetramethylenephosphonic acid and (2) at least one of the above aminophosphonic acids, or a physiologically acceptable salt thereof, in excess of that required to make the complex.
A method for the therapeutic treatment of an animal having one or more calcific tumors which comprises administering to said animal a therapeutically effective amount of a composition comprising (1) a complex which comprises Sm-153 and ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof and (2) ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof, in excess of that required to make the complex.
A sterile composition suitable for administration to a mammal comprising (1) a complex which comprises Sm-153 and at least one of an aminophosphonic acid or a physiologically acceptable salt thereof wherein the aminophosphonic acid is selected from the group consisting of ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid hydroxyethylethylenediaminetrimethylenephosphonic acid, tris(2-aminoethyl)aminehexamethylenephosphonic acid, bis(aminoethyl)piperazinetetramethylenephosphonic acid, and (1-carboxy)ethylenediaminetetramethylenephosphonic acid and (2) at least one of the above aminophosphonic acids, or a physiologically acceptable salt thereof, in excess of that required to make the complex, and wherein the resulting composition is therapeutically effective and wherein the Sm-153 in dosage form is present in an amount containing at least 0.02 mCi per kilogram of body weight of said mammal.
A sterile composition suitable for administration to a mammal comprising (1) a complex which comprises Sm-153 and ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof and (2) ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof, in excess of that required to make the complex, and where in the resulting composition is therapeutically effective and wherein the Sm-153 in dosage form is present in an amount containing at least 0.02 mCi per kilogram of body weight of said mammal.
A method for the therapeutic treatment of an animal having bone pain which comprises administering to said animal a therapeutically effective amount of a composition comprising (1) a complex which comprises Sm-153 and at least one of an aminophosphonic acid or a physiologically acceptable salt thereof wherein the aminophosphonic acid is selected from the group consisting of ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, hydroxyethylethylenediaminetrimethylenephosphonic acid, tris(2-aminoethyl)aminehexamethylenephosphonic acid, bis(aminoethyl)piperazinetetramethylenephosphonic acid, and (1-carboxy)ethylenediaminetetramethylenephosphonic and (2) at least one of the above aminophosphonic acids, or a physiologically acceptable salt thereof, in excess of that required to make the complex.
A method for the therapeutic treatment of an animal having bone pain which comprises administering to said animal a therapeutically effective amount of a composition comprising (1) a complex which comprises Sm-153 and ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof and (2) ethylenediaminetetramethylenephosphonic acid or a physiologically acceptable salt thereof, in excess of that required to make the complex.
