The Copper-67 (Cu-67) Advantage
How do Cu-67 characteristics compare to other therapeutic radioisotopes?
In short, Cu-67 has ideal therapeutic radionuclide characteristics, particularly when paired with chemically identical Cu-64 or Cu-61 for diagnostic imaging.
Cu-67 is a versatile and effective therapeutic radioisotope, creating an ideal theranostic
- Cu-67 has near-ideal characteristics as a therapeutic radioisotope
- Cu-67's beta emission energy, half life, imageable gamma energies, and centralized production make it highly effective and versatile
- Cu-67 labeled therapeutic radiopharmaceuticals may be paired with chemically identical Cu-64 or Cu-61 labeled diagnostic radiopharmaceuticals to produce a "perfect theranostic pair"
- New chelator technologies provide chemical versatility, with the potential for Cu-67 to bind to a broad range of ligands
- Cu-67 emits gamma radiation which can be imaged using single photon emission computed tomography (SPECT) scanners, enabling assessment of cancer target binding, and informing decisions regarding subsequent patient treatment
