NCT04256993

Brief Summary

In this observational study researchers want to gather more information about bone fractures and survival in castration-resistant prostate cancer (CRPC) patients treated with radium-223 in routine clinical practice in Sweden. The goal is to estimate the proportion of new cases (incidence) of symptomatic bone fractures and to estimate the proportion of death occurred in years of observation time per person (person years). Radium-223 (Ra-223) is an alpha particle-emitting radioactive agent approved for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC).

Outcome Measures

Primary Outcomes (1)

  • Bone fractures requiring admission to a hospital or treated in an outpatient setting, as recorded or captured in the PCBaSe

    PCBaSe: Prostate Cancer data Base Sweden

    Retrospectively analysis from November 2013 to December 2018

Secondary Outcomes (2)

  • Death due to all causes

    Retrospectively analysis from November 2013 to December 2018

  • Death due to prostate cancer

    Retrospectively analysis from November 2013 to December 2018

Study Arms (2)

Ra-223 initiators

Patients diagnosed with mCRPC (Metastatic Castration-Resistant Prostate Cancer) who start treatment with Ra-223. Patients will be identified from the "Patient-overview Prostate Cancer" (PPC), a sub-registry of the Prostate Cancer data Base Sweden (PCBaSe) data set.

Drug: Radium-223 dichloride (Xofigo, BAY88-8223)

Initiators of other standard of care

The comparator cohort will be patients using standard of care other than Ra-223.

Drug: Other standard care

Interventions

Follow the physician's prescription in routine clinical practice. This study does not involve prescription of the drugs.

Ra-223 initiators

Docetaxel, cabazitaxel, enzalutamide, abiraterone and others standard of care following the physician's prescription in routine clinical practice.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study population comprises men with mCRPC in the PPC (Patient-overview Prostate Cancer) PCBaSe data set during the study time frame, with the potential addition of men with mCRPC in the Karolinska Institutet data sets.

You may qualify if:

  • Histologically confirmed adenocarcinoma of the prostate, i.e., the patient is registered in the NPCR (histology other than adenocarcinomas are not registered in the NPCR).
  • Start of Ra-223 treatment for mCRPC as an n-th line of treatment, where "n" goes from 1 to 4.
  • ECOG performance status of 0-2 at treatment initiation. We will assume that patients starting any of the systemic therapies under study have a performance status of 0-2.

You may not qualify if:

  • Prior use of Ra-223
  • Patients that have participated in a Ra-223 RCT
