The
Science
Therapeutic radiopharmaceuticals are a safe and effective targeted approach to treating many types of cancer and serious diseases. NorthStar is routinely producing Cu-67 poised to be one of the first commercial-scale producers of Ac-225. Both are used to deliver precise therapeutic doses of radiation to destroy cancer cells in patients while sparing healthy tissue.
HOW DOES Radiopharmaceutical
THERAPY WORK?

Radiopharmaceuticals suited for therapeutic purposes are those that strongly bind to the tumor.

They transport targeted doses of radiation directly to the tumor and its metastases, thereby sparing normal healthy tissue.

The carrier molecule type, such as antigens or receptors, is determined by its affinity to the tumor’s structure.

The ionizing radiation emitted by a radionuclide linked to the carrier, kills cancer cells by damaging their DNA, causing the tumors to shrink.
