A research called CREDIT studies how safe the study treatment Radium-223 is and how well it works in Chinese men with advanced prostate cancer that has spread to the bones and does not respond to treatments for lowering testosterone levels (CREDIT)
This is an observational study in which data from Chinese men with metastatic castration-resistant prostate cancer that has spread to the bones and who start Radium-223 therapy is studied.
When tumors form in the prostate, male hormones like testosterone will cause the spread and growth of tumors. Men with prostate cancer can have hormonal or surgical treatment that lowers testosterone. But this may not stop the cancer from growing or spreading in some men. When the prostate cancer is no longer responding to therapies aimed at lowering testosterone (castration resistant) and has spread to the bones (metastatic), it is referred to as bone metastatic castration-resistant prostate cancer.
The study treatment, Radium-223 (also called Xofigo), gives off radiation that helps to kill cancer cells. It is already approved to be used for men whose prostate cancer has spread to the bone with symptoms, but not to be used for other types of tumors or for prostate cancer that has spread to other parts of the body. Sometimes, after the approval of some drugs, researchers will further study the safety of such approved treatments in patients being treated in routine clinical practice.
In this study, researchers want to learn more about the medical problems that may occur in Chinese patients after they start Radium-223 therapy, especially those problems concerning the blood and blood-forming organs. To answer this question, the researchers will observe patients who start Radium-223 as part of their routine care and also collect information of any medical problems happening after Radium-223 injections from the medical records of these patients. These medical problems may or may not be related to Radium-223 and are also known as adverse events.
The researchers will assess the percentage of men who developed medical problems concerning the blood and blood-forming organs from the start of Radium-223 injection till up to 6 months after the last Radium-223 injection.
The researchers will also collect data on the time the participants live after start of treatment, the change in pain severity, and the time between the end of Radium-223 treatment and the beginning of the following therapy against the cancer.
Besides the data collection, no further tests or examinations of any patients or any samples are planned in this study. The participants will start Radium-223 treatment as part of their routine care as prescribed by their doctors according to the recommended use. Data collection of each participant will last until the participant leaves the study or until the study ends. The study is planned to end 6 months after the last included participant receives the last injection of Radium-223.
