Radium-223 Dichloride Long-term Follow-up Program

This long-term follow up study will enroll subjects who will be transferred from selected interventional, company sponsored trials with radium-223 dichloride (feeder trials).

The primary objectives are to define the long term safety profile of radium-223 dichloride (for up to 7 years after the last dose of radium-223 dichloride); to assess the incidence of leukemia, myelodysplastic syndrome, aplastic anemia, and primary bone cancer or any other new primary malignancy; to assess the incidence of bone fractures and bone associated events (e.g., osteoporosis); and, in subjects who receive cytotoxic chemotherapy, to assess the incidence of febrile neutropenia and hemorrhage during their chemotherapy treatment and for up to 6 months thereafter at a frequency based on local clinical practice.
