BAY88-8223, Does Response Study in HRPC Patients
A Double Blind, Dose Response Phase II, Multicentre Study of Radium 223 (Alpharadin®) for the Palliation of Painful Bone Metastases in Hormone Refractory Prostate Cancer Patients
Study Overview
Status
Intervention / Treatment
Detailed Description
The study is designed to investigate whether there is a dose-response relationship for radium-223 in patients with painful bone metastases secondary to prostate carcinoma regarding palliation of bone pain. The palliative efficacy will be established through assessments of bone pain and consumption of analgesia. Furthermore, the aim is to find the most efficient dose with an acceptable safety profile. The safety will be assessed through measurements of adverse events, and acute haematological toxicity during the study period. Long-term chronic toxicity, and the overall survival at one and two years post treatment will also be assessed.
This is a double-blind, dose-response, randomized, multi-centre phase II efficacy and safety study of radium- 223. The clinical sites will enroll a total of 100 eligible patients. The treatment is a single intravenous administration of radium-223.
The target population is patients suffering from bone pain due to skeletal metastasis secondary to hormone refractory prostate cancer.

Description
Inclusion criteria:
- Histologically/cytologically confirmed adenocarcinoma of the prostate
Patient is hormone refractory with evidence of progressive disease:
- Patient must be maintained on androgen ablation therapy with LHRH agonist or have undergone orchiectomy
- Patient's testosterone level is required to be equal to or below 50 ng/dl
- Patients in which flutamide, nilutamide, megestrol acetate, polyestradiol phosphate, aminoglutethimide, and ketoconazole, has been recently withdrawn must demonstrate progression of disease and be at last 4 weeks beyond the discontinuation of such agents; for bicalutamide 6 weeks is required
Increase in PSA levels in two consecutive measurements with at least one week apart, demonstrating an increase over the reference (nadir) value, and with the final PSA >/= 5 ng/ml
- A reference PSA (nadir) value must be measured at least 4 weeks after the discontinuation of flutamide, nilutamide, megestrol acetate, polyestradiol phosphate, aminoglutethimide, and ketoconazole, and at least 6 weeks after discontinuation of bicalutamide
- If the third PSA value is lower than the second value, the patient could still be eligible, provided a fourth measurement obtained at least 1 week after the third PSA value, is grater than the second PSA value and >/= 5 ng/ml
- Multifocal (>1) skeletal metastases confirmed by bone scintigraphy within 6 weeks
- Bone pain with a score of at least 2 on BPI average pain, despite adequate use of analgesics, that correlates with areas of increased uptake (osteoblastic activity) on bone scintigraphy
- Performance status: ECOG 0-2 or Karnofsky >/= 60%
- Life expectancy: At least 3 months
- Age more than 40 years
Laboratory requirements:
- Neutrophil count >/= 1,5 x 109/L
- Platelet count >/= 100 x109/L
- Hemoglobin > 95 g/L
- Bilirubin within normal institutional limits
- ASAT and ALAT <2,5 times upper limit of normal (ULN)
- The patient is willing and able to comply with the protocol (including maintenance of patient diary, completion of pain assessment forms), and agrees to return to the hospital for follow-up visits and examinations
- The patient has been fully informed about the study and has signed the informed consent form
Exclusion criteria
- Has received an investigational drug within 4 weeks before the administration of radium-223, or is scheduled to receiving one during the study period
- Has received chemo-, immunotherapy, or external radiotherapy within the last 4 weeks prior to entering the study, or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- Has received prior hemibody external radiotherapy
- Has received systemic radiotherapy with strontium-89, samarium-153, rhenium-186 or rhenium 188 for the treatment of bony metastases within the last year prior to inclusion
- Has started treatment with bisphosphonates less than 3 months prior to administration of study drug
- Patients experiencing hormone withdrawal syndrome, or are </= 4 weeks post withdrawal of antiandrogen therapy (6 weeks for bicalutamide)
- Patients who have started steroids or changed to treatment with steroids within the last 4 weeks prior to administration of radium-223
- Has other clinically significant or symptomatic disease, which might interfere with the assessment of bone pain, e.g. spinal cord compression, compression or infiltration of a neural plexus, nerve root or peripheral nerves
- Other currently active (relapse within the last 3 year) malignancy (except non-melanoma skin cancer), or known brain or visceral metastases dominating the clinical picture of the patient
Other serious illness or medical condition:
- any uncontrolled infection
- cardiac failure Classification III or IV (New York Heart Association)
- Crohn disease or Ulcerative colitis
- known bone fracture within 8 weeks

Intervention / Treatment |
---|---|
Experimental: Radium-223 dichloride (Xofigo, BAY88-8223)-5kBq/kg
Each patient received a single injection of radium-223 , based on the randomised dose level (5kBq/kg) and individual body weight. A second injection of radium-223 set to 50 kBq/kg b.w. could be offered to patients in the Follow-up Period at the discretion of the investigator. |
The required volume of study drug to be administered to a patient was calculated using the patient's body weight, the dose (5 , 25 , 50 or 100 kBq/kg b.w.)
|
Experimental: Radium-223 dichloride (Xofigo, BAY88-8223)-25 kBq/kg
Each patient received a single injection of radium-223 , based on the randomised dose level (25kBq/kg) and individual body weight. A second injection of radium-223 set to 50 kBq/kg b.w. could be offered to patients in the Follow-up Period at the discretion of the investigator. |
