A Registry Based Study Evaluating Overall Survival and Treatment Length in mCRPC Patients Treated With Enzalutamide in Sweden

August 15, 2019 updated by: Astellas Pharma a/s

The purpose of this study is to provide real world data on treatment with enzalutamide in metastatic castration-resistant prostate cancer (mCRPC) patients.

The primary purpose is to evaluate overall survival (OS) in mCRPC patients treated with enzalutamide who have previously undergone treatment with chemotherapy (docetaxel) (post chemo patients).

This study will also evaluate treatment duration with enzalutamide in patients pre- and post-chemo.

Study Population

Patients with mCRPC initiating treatment with enzalutamide pre- and post- chemo registered in the prostate cancer registry.

Description

Inclusion criteria:

  • Chemo naïve mCRPC patients treated with enzalutamide and ongoing androgen deprivation therapy with a gonadotropin releasing hormone (GnRH) analogue or orchiectomy (i.e., surgical or medical castration).
  • mCRPC patients treated with enzalutamide and ongoing androgen deprivation therapy with a gonadotropin releasing hormone (GnRH) analogue or orchiectomy (i.e., surgical or medical castration) post chemo.

Exclusion Criteria

  • mCRPC patients previously exposed to Radium-223, abiraterone acetate and/or cabazitaxel for mCRPC (pre- and post chemotherapy).
  • Patients previously exposed to chemotherapy or abiraterone acetate+prednisolone in combination with GnRH analogue for hormone sensitive prostate cancer (HSPC).
