About radium Ra 223 dichloride
Radium Ra 223 dichloride (radium 223) is currently not approved by the
Radium 223 (as Xofigo(®) injection) is approved in
Radium 223 is an alpha particle-emitting radioactive therapeutic agent with an anti-tumor effect on bone metastases. The active ingredient in radium 223 is the alpha particle-emitting isotope radium-223, which mimics calcium and forms complexes with the bone mineral hydroxyapatite at areas of increased bone turnover, such as bone metastases. The high linear energy transfer of radium- 223 may cause double-strand DNA breaks in adjacent cells, resulting in an anti- tumor effect on bone metastases. The alpha particle range from radium-223 is less than 100 micrometers which may limit the damage to the surrounding normal tissue.
Important Safety Information for Xofigo (radium Ra 223 dichloride) in the US
Xofigo is contraindicated in women who are or may become pregnant. Xofigo can cause fetal harm when administered to a pregnant woman.
In the randomized trial, 2% of patients in the Xofigo arm experienced bone marrow failure or ongoing pancytopenia, compared to no patients treated with placebo. There were two deaths due to bone marrow failure. For 7 of 13 patients treated with Xofigo bone marrow failure was ongoing at the time of death. Among the 13 patients who experienced bone marrow failure, 54% required blood transfusions. Four percent (4%) of patients in the Xofigo arm and 2% in the placebo arm permanently discontinued therapy due to bone marrow suppression. In the randomized trial, deaths related to vascular hemorrhage in association with myelosuppression were observed in 1% of Xofigo-treated patients compared to 0.3% of patients treated with placebo. The incidence of infection-related deaths (2%), serious infections (10%), and febrile neutropenia (less than 1%) was similar for patients treated with Xofigo and placebo. Myelosuppression - notably thrombocytopenia, neutropenia, pancytopenia, and leukopenia - has been reported in patients treated with Xofigo.
