E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

|
E.2.2 | Secondary objectives of the trial |
To demonstrate superiority in the progression-free survival (PFS) of patients with progressive mHRPC treated with SP versus PP after failure of a docetaxel-based chemotherapy regimen.
To compare the objective response rate (ORR) and duration of response (DR) in patients with progressive mHRPC treated with SP versus PP after failure of a docetaxel-based chemotherapy regimen.
To compare patient reported outcomes (PROs) of pain severity, health-related quality of life, prostate cancer-specific symptoms, and general health status in patients with progressive mHRPC treated with SP versus PP after failure of a docetaxel-based chemotherapy regimen.
To evaluate the safety and tolerability of sunitinib in combination with prednisone. |

MOLECULAR PROFILING SUPPLEMENT, version and date: Final, 22 February 2008.
Title: A MULTICENTER, RANDOMIZED, DOUBLE-BLIND, PHASE 3 STUDY OF SUNITINIB PLUS PREDNISONE VERSUS PREDNISONE IN PATIENTS WITH PROGRESSIVE METASTATIC HORMONE-REFRACTORY PROSTATE CANCER AFTER FAILURE OF A DOCETAXEL-BASED CHEMOTHERAPY REGIMEN
Objectives: The primary objective of this additional research component is to collect, store, and use samples to investigate possible associations between genomic and metabonomic variation:
• in relation to response to the study drugs, and • in relation to characteristics of the disease/condition under study in the associated clinical trial, and related conditions.
In addition, samples may be used as controls in genomic and metabonomic investigations of the causes, natural history, and other aspects of important diseases and conditions for which Pfizer is researching new or improved drug therapies.
Scientific information about these differences among groups of subjects can help researchers to better understand the response of subjects to investigational drugs and to learn more about diseases/conditions for which we are developing treatments. Samples collected will be stored in Pfizer’s Exploratory Research Biobank in the USA.

E.3 | Principal inclusion criteria |
1. Histologically- or cytologically-confirmed adenocarcinoma of the prostate. 2. Metastatic hormone-refractory prostate cancer (refractory to androgen ablation). Patients must have surgical or ongoing chemical castration, with baseline testosterone level <50 ng/dL. 3. Patients must have disease that has failed one prior docetaxel-based chemotherapy regimen for the treatment of metastatic disease, defined as progression of disease on or after treatment (docetaxel-resistant), or be considered docetaxel-intolerant (discontinued treatment due to unacceptable toxicity, as judged by the treating physician or by the patient). In the event both disease progression and drug intolerance are observed during prior docetaxel-based treatment, disease progression will be considered the dominant entry criterion. 4. Patients must have documented evidence of progressive disease defined by either: • PSA progression: minimum of 2 rising values (3 measurements) obtained a minimum of one week apart with the last result being at least 2.0 ng/mL, • RECIST, or • Positive bone scan with 2 or more new lesions. 5. ECOG performance status 0 or 1. 6. Resolution of all acute toxic effects of prior therapy (except for alopecia and neuropathy) or surgical procedure to grade ≤1 or to baseline prior to therapy. 7. Adequate organ function as defined by the following criteria: • Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase [SGOT]) and serum alanine transaminase (ALT; serum glutamic pyruvic transaminase [SGPT]) ≤2.5 x upper limit of normal (ULN), ≤5 x ULN for patients with liver metastases • Total serum bilirubin ≤1.5 x ULN • Absolute neutrophil count (ANC) ≥1500/µL • Platelets ≥100,000/µL • Hemoglobin ≥9.0 g/dL • Serum creatinine ≤2 x ULN • QTc interval ≤470 msec • Left ventricular ejection fraction (LVEF) ≥lower limit of institutional normal (LLN) as assessed by multigated acquisition (MUGA) scan or echocardiogram 8. Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment. 9. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures, including the completion of patient reported outcomes questionnaires and an analgesic use diary. |
|
E.4 | Principal exclusion criteria |
1. Prior treatment with sunitinib (in any clinical setting) and/or more than one prior chemotherapy regimen in the metastatic disease treatment setting. 2. Chemotherapy within 3 weeks of study entry. 3. Radioisotope therapy with Strontium-89 or Samarium within 12 weeks prior to study entry. 4. Radiation therapy (including palliative radiotherapy to metastatic lesion(s)) within 2 weeks or major surgery (e.g., open abdominal, pelvic, thoracic, orthopedic or neurosurgery) within 4 weeks prior to study entry. 5. Current treatment on another therapeutic clinical trial. 6. Impending complication from bone metastasis (fracture and/or cord compression). 7. Presence of ongoing urinary obstruction (e.g., urinary retention, hydronephrosis) requiring medical intervention. Properly treated urinary obstruction is allowed. 8. Grade ≥3 hemorrhage within 4 weeks prior to study entry. 9. Ongoing cardiac dysrhythmias of grade ≥2. 10. Hypertension that cannot be controlled by medications (>150/100 mmHg despite optimal medical therapy). 11. Ongoing treatment with therapeutic doses (with therapeutic INR levels) of coumarinderivatives or oral anti-vitamin K agents. 12. Diagnosis of any second malignancy within the last 3 years, except basal cell carcinoma, squamous cell skin cancer, stage I carcinoma fully treated, or in situ carcinoma that have been adequately treated with no evidence of recurrent disease for 12 months. 13. Any of the following within the 6 months prior to study drug administration: severe/unstable angina, myocardial infarction, symptomatic congestive heart failure, pulmonary embolism, cerebrovascular accident, or transient ischemic attack. 14. Known or suspected brain metastases (skull metastases allowed), spinal cord compression, carcinomatous meningitis, or leptomeningeal disease. 15. Known human immunodeficiency virus (HIV) infection. 16. Other severe acute or chronic medical or psychiatric condition, or laboratory abnormality that would impart, in the judgment of the investigator, excess risk associated with study participation or study drug administration, or which, in the judgment of the investigator would make the patient inappropriate for entry into the trial |
