Clinical Trial Summary

In this study researcher want to learn more about the overall survival in patients suffering from prostate gland cancer which spread outside the prostate to other parts of the body who received either a novel anti-hormone therapy (NAH) or Radium-223 (Xofigo) after a prior NAH therapy (first line treatment). Additionally the researchers are also interested in the occurrence of bone fractures and other skeletal events. Basis for this study will be the US based Flatiron database which provides access to clinical data for cancer patients.

Related Conditions & MeSH terms

• Metastatic Castration-resistant Prostate Cancer (mCRPC)
• Prostatic Neoplasms

Intervention

Drug:
• Radium-223 (Xofigo, BAY88-8223)
Ra-223 was approved by the FDA in May 2013 for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases and no known visceral metastatic disease.
• Abiraterone
Abiraterone is a CYP17 inhibitor. It was approved by the FDA for the treatment of patients with mCRPC in 2011, and for patients with metastatic high-risk castration-sensitive prostate cancer in 2018.
• Enzalutamide
Enzalutamide is an androgen receptor inhibitor. It was approved by the FDA for the treatment of patients with mCRPC in 2012, with warning and precautions added in 2017 regarding the risk of seizure and encephalopathy.
