  • Publication number: 20200297877
    Abstract: The present invention relates to complexes comprising a prostate-specific membrane antigen (PSMA) targeting compound linked to a radionuclide, such as 212Pb or 227Th, through a TCMC or DOTA chelating moiety. These compounds, and pharmaceutical compositions comprising them, can be used for medical applications. These applications include the treatment of prostate cancer, and the complexes allow for dual targeting of cancers.

  • Patent number: 10434198
    Abstract: The present invention relates to radiopharmaceutical compositions comprising the mother nuclide 224Ra, its daughter nuclide 212Pb, and a complexing agent that complexes with the daughter nuclide. The use of targeted chelate scavengers for 224Ra daughter nuclide opens up the possibility for using 224Ra based solutions for medial treatments.

  • Patent number: 9433690
    Abstract: Methods and solutions are describes whereby radiopharmaceutical radium-224 solutions are added complex for scavenging daughter nuclide, which may enhance the overall targeting and reduces uptake of daughter nuclide in normal tissues and cells. This is accomplished without reducing the bone targeting ability of radium. The methods and solutions are convenient to use since the complexation of daughter nuclide can be done in situ in a ready to use radiopharmaceutical solution or, depending on the activity concentration, in a simple kit format by mixing two solutions and store the mixture for typically 1 minute to a few hours before administration to a patient. The use of targeted chelate scavengers for 224Ra daughter nuclide opens up the possibility for using 224Ra based solutions for medical treatments.
