E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the effect of ZD4054 on time to progression in metastatic hormone refractory prostate cancer, which will recommend a dose of ZD4054 for use in future studies. |
|
E.2.2 | Secondary objectives of the trial |
1. To investigate the effect of ZD4054 on the time to death. 2. To investigate the effect of ZD4054 on PSA. 3. To investigate the tolerability and safety profile of ZD4054 at the studied doses. 4. To investigate the effect of ZD4054 on objective response rate. 5. To investigate the pharmacokinetic characteristics of ZD4054. 6. To investigate the rate of development of new bone lesions.

E.3 | Principal inclusion criteria |
1. Provision of written informed consent to participate in the study 2. Male, aged 18 years or older 3. Surgically castrated or continuously medically castrated with luteinising hormone-releasing hormone (LHRH) analogue 4. Patients with a serum testosterone inferior or equal to 1.73 nmol/L (50 ng/dL) 5. Histological or cytological confirmation of adenocarcinoma of the prostate. 6. Documented evidence of bone metastases, as assessed by bone scintigraphy performed according to the standard bone acquisition protocol developed specifically for this study. - Patients must have disease involvement of less than 75% of the spine, 75% of the pelvis or 75% of the ribs in the anteroposterior (AP) or posteroanterior (PA) view. - Patients with inferior or equal to 3 hot spots on the bone scan will require an additional scan to confirm metastatic disease, such as CT, magnetic resonance imaging (MRI) or X-ray, to be determined by the investigator. 7. Biochemical progression of prostate cancer, documented while the patient is castrate, by a rise in PSA that meets any one or more of the following criteria: Biochemical progression criterion 1: A second PSA value higher than a first PSA (reference) value. To be followed by a third PSA value higher than the second value. - 2 weeks minimum time interval between sampling - All samples must have been taken within a 6-month period of randomisation to the study - All PSA values must be superior or equal to 5 ng/mL Biochemical progression criterion 2: A second PSA value higher than a first PSA (reference) value. Followed by a third PSA value lower than the second, but with a fourth PSA value higher than the second. - 2 weeks minimum time interval between sampling - All samples must have been taken within a 6-month period of randomisation to the study - All PSA values must be superior or equal to 5 ng/mL Biochemical progression criterion 3: A PSA value greater than or equal to a doubling of a first PSA (reference) value. This must be confirmed by an additional PSA assessment which is also greater than or equal to a doubling of the reference value. - 2 weeks minimum time interval between sampling - All samples must have been taken within a 6-month period of randomisation to the study - All PSA values must be superior or equal to 5 ng/mL Historical values may be used if they have been obtained from the same laboratory using the same PSA assay. 8. Creatinine clearance of >60 mL/minute, determined using the Cockcroft-Gault equation or by 24-hour creatinine clearance. 9. World Health Organisation (WHO) performance status 0 – 1 . 10. Life expectancy of 6 months or more 11. Clearly understand and be likely to comply with all study procedures

E.4 | Principal exclusion criteria |
1. Current use (from the time that written informed consent is given) of any opiates listed in Appendix E of the protocol. 2. Prior radiotherapy to bone metastases within 4 weeks of randomisation to the study. 3. Prior cytotoxic chemotherapy for the treatment of their recurrent prostate cancer, such as estramustine, paclitaxel, docetaxel and mitoxantrone. 4. Corticosteroids, including hydrocortisone, for the treatment of their recurrent prostate cancer within 4 weeks of randomisation to the study. Please note that if taking corticosteroids for another reason, the treatment must be at a dose that is stable for a minimum of 12 weeks prior to randomisation to the study. 5. Antiandrogens, within 4 weeks of randomisation to the study for flutamide or within 6 weeks of randomisation to the study for bicalutamide and nilutamide. Continued elevation of their PSA, according to inclusion criterion number 7 (see Section 3.3.2 in the protocol), can be demonstrated during the washout times provided above. 6. Treatment with strontium-89, rhenium-186-HEDP and samarium-153-EDTMP for bone metastases, within 12 weeks of randomisation to the study. 7. Neurologic symptoms or signs consistent with acute or evolving spinal cord compression, confirmed with MRI. Stable, previously treated patients are allowed. 8. Stage II, III or IV cardiac failure, classified according to New York Heart Association (NYHA) classification. 9. QT interval corrected for heart rate (QTc) >470 msec. 10. In the opinion of the investigator, any evidence of severe or uncontrolled systemic disease, (eg, currently unstable or uncompensated respiratory, cardiac, hepatic or renal disease) or evidence of any other significant clinical disorder or laboratory finding that makes it undesirable for the patient to participate in the study. 11. Epilepsy or other seizure disorder, unless agreed upon by AstraZeneca. 12. Central nervous system metastases. 13. Total serum bilirubin greater than 1.5 times the upper limit of reference range (ULRR). 14. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than 1.5 times the ULRR. 15. Haemoglobin inferior or equal to 9 g/dL, neutrophils <1.5 x 109/L or platelets <75 x 109/L. 16. Prior therapy with endothelin receptor antagonists 17. Current therapy, or therapy within 2 weeks of randomisation to the study, with indinavir, itraconazole, ketoconazole and ritonavir (highly potent inhibitors of CYP450 3A4). 18. Current therapy, or therapy within 2 weeks of randomisation to the study, with carbamazepine, phenobarbitone, phenytoin, rifampicin and St John’s Wort (highly potent CYP450 inducers). 19. Use of systemic retinoids and herbal medicines or remedies (specifically, but not exclusively, to include saw palmetto and PC SPES), within 2 weeks of randomisation to the study. 20. Any serious condition which, in the opinion of the investigator, would present a risk to the patient participating in this study. 21. Have received investigational drug in another clinical study of anti-cancer therapy, within 4 weeks prior to consenting to this study. Please note restriction number 1 on bisphosphonates (see Section 3.3.4 in the protocol).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint for this study is defined as time to progression (TTP). The endpoint is in fact a composite of objective and clinical measures of disease progression. This reflects the difficulty encountered in clinical practice of determining objective progression of prostate cancer metastatic to bone. However it is anticipated that the endpoint will provide data on the impact of study drug on disease progression as reflected by routine clinical management of the disease. |
