About this study
Official title: Phase II Open-label Study to Evaluate the Efficacy and Safety of Radium in Combination With External Beam Radiotherapy (EBRT) vs. EBRT Alone in the Treatment of Castration Resistant Prostate Carcinoma With Limited Bone Metastases
Phase II open-label study to evaluate the efficacy and safety of Radium-223 dichloride in combination with external beam radiotherapy (EBRT) vs. external beam radiotherapy alone in the treatment of advanced castration resistant prostate carcinoma with limited bone metastases.
To evaluate if time to radiological progression according to the "Recommendations of the Prostate Cancer Clinical Trials Working Group" published by Scher et al. (JCO 2008) (based on new lesions in bone scan and CT /MRI or death) of Radium-223 dichloride combined with EBRT is superior compared to EBRT alone.
Read the detailed description
This is an international, multi-center, open-label, prospective, phase II study designed to assess the efficacy of radiation therapy in combination with Radium-223 dichloride in patients diagnosed with CRPC and oligo metastases bone disease. All patients enrolled in this study will have signed an informed consent form (ICF) and will adhere to all inclusion and exclusion criteria.
During the treatment period, patients will be followed on an ongoing basis for safety and quality of life (QoL). Safety assessments will include the collection of all AEs of any grade, serious adverse events (SAEs), adverse event (AEs) corresponding to symptoms arising from bone metastases, laboratory values, (WHO/ECOG) performance status (PS). Documentation of the date of disease progression will be performed at intervals and imaging methods (bone scans and CR/MRI) described in the study protocol. Quality of life will be measured by patient assessment using a validated questionnaire, the Brief Pain Inventory Short Form (BPI-SF), the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ)-C15-PAL and the EORTC QLQ- Bone Metastases (BM) 22. Follow-up assessments for safety AEs and SAEs, and the occurrence of secondary malignancies will be conducted every 3-12 months until the patient dies or until the study is terminated by the sponsor. If the patient can no longer travel to the clinical site, he will be followed up for survival only, i.e., the long term follow-up phase of the study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Radium-223 dichloride and Conventional or high dose radiotherapy in people with Prostate Carcinoma, run by University Hospital Freiburg at 6 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ursula Nestle, Prof.Dr. (alpha-radiotherapy@uniklinik-freiburg.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time to radiological progression free survival (PFS) rate (time frame: randomization to radiological progression). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2016; AzTrials last refreshed its copy on 7 Nov 2026.
