Prostate Carcinoma Clinical Trial
— a-RTOfficial 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.

Eligibility |
Inclusion Criteria: 1. Has provided written informed consent. Subjects must be able to understand and be willing to sign the written informed consent form (ICF). Age = 18 and = 85 years 2. Patients with progressive castration resistant prostate cancer (CRPC) with 1-5 bone metastases for whom Radium-223 dichloride constitutes first-line cytostatic treatment 3. Primary tumor (and its local recurrence, if applicable) controlled by effective local treatment 4. If diagnosed, pelvic lymph node metastases controlled by effective local treatment 5. At least 1 not previously locally treated skeletal metastasis on bone scan without non-bone distant metastases (e.g. lung, liver, and/or brain metastases) and without pathologically enlarged lymph nodes above the pelvis 6. Progressive disease is defined either by: - The appearance of new bone lesions. If progression is based on new lesion(s) on bone scan only without an increase in prostate specific antigen (PSA), PSA values from 3 assessments within the last 6 months must be provided; OR - In the absence of new bone lesions by 2 consecutive increases in serum PSA over previous reference value, which should not be more than 6 months before screening, each measured at least 1 week apart with the last PSA =5 ng/mL 7. Life expectancy of at least 6 months. 8. (WHO/ECOG) Performance Status (PS) 0 or 1 9. Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements to be conducted within 7 days prior to start of therapy: 10. Patient has or has had symptoms (e. g. pain or micro) Exclusion Criteria: Excluded medical conditions: 1. More than 5 not previously locally treated bone metastases as diagnosed by bone scintigraphy; 2. Visceral or lymph node metastases above the pelvis as assessed by computed tomography (CT) (or other imaging modality) ; 3. History of HIV infection or chronic hepatitis B or C 4. Active clinically serious infections (> grade 2 National Cancer Institute Common Terminology Criteria (NCI-CTC) version 4.03) 5. History of organ allograft 6. Patients undergoing renal dialysis 7. Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study if not in complete remission for at least 5 years since date of diagnosis treated treated basal cell carcinoma, superficial bladder tumors [Ta, Tis & T1] or any cancer curatively treated > 3 years prior to study entry. 8. Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results 9. Imminent or history of spinal cord compression based on clinical findings and/or magnetic resonance imaging (MRI) 10. Any other serious illness or medical condition 11. Fecal incontinence 12. Any condition that is unstable or could jeopardize the safety of the patient and his compliance in the study 13. Known allergy to Radium-223 dichloride (i.e. to active substance or one of the constituents) Excluded therapies and medications, previous and concomitant: 1. Anticancer chemo- or targeted therapy for CRPC 2. Radiotherapy for prostate cancer manifestations other than study treatment if not given with curative intent to prostate fossa and/or pelvic lymph nodes 3. Major surgery within 4 weeks of study entry. 4. Systemic therapy with radionuclides for the treatment of bone metastases 5. Autologous bone marrow transplant or stem cell rescue within 4 months of study entry 6. Use of biologic response modifiers, such as Granulocyte-Colony Stimulating Factor (G-CSF), within 3 week of study entry 7. Investigational drug therapy outside of this trial during or within 4 weeks of study entry |
