EPIX, a Study to Gather More Information About Characteristics of Patients and Other Factors Which May Contribute to Survival Over a Long Period of Time in Patients With Metastatic Castration-resistant Prostate Cancer (mCRPC) Treated With Radium-223 (Xofigo)
Overview
In this observational study researchers want to gather more information about the characteristics of patients treated with Radium-223 (Xofigo) who had survived over a long period of time prostate cancer that had spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels (metastatic castration-resistant prostate cancer, mCRPC). In addition researchers want to identify the factors which may contribute to survival over a long period of time in those patients. Radium-223 (Ra-223) is an alpha particle-emitting radioactive agent approved for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC).

Study Type
- Study Type: Observational
- Study Design
- Time Perspective: Retrospective
- Study Primary Completion Date: March 31, 2021
Interventions
- Drug: Radium-223 dichloride (Xofigo, BAY88-8223)
- Receiving Ra-223 either alone or in combination with other cancer therapies at any time after diagnosis of mCRPC
Arms, Groups and Cohorts
- Radium-223 dichloride (Xofigo, BAY88-8223)
- Patients with mCRPC who received treatment of Ra-223.
Clinical Trial Outcome Measures
Primary Measures
- Overall survival from initiation of Ra-223
- Time Frame: Retrospective analysis from Jan 2013 to Dec 2019
Secondary Measures
- Percentage of Prostate Specific Antigen (PSA) (unit: µg/L) response after Ra-223
- Time Frame: Retrospective analysis from Jan 2013 to Dec 2019
- PSA response will be defined ≥ 50% reduction in baseline PSA level after initiation of Ra-223
