Sorafenib to Overcome Resistance to Systemic Chemotherapy in Androgen-independent Prostate Cancer

Completed · Phase 1/Phase 2

Conditions studied: Prostate Cancer

Who can join

Age: 18 and older, up to 90. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Age > 18 years old
• Eastern Cooperative Oncology Group (ECOG) Performance Status 0, 1, or 2.
• Patients with a known diagnosis of prostate cancer regardless of their Gleason grade.
• Patients have AIPC.
• Adequate bone marrow, liver and renal function as assessed by:
• Hemoglobin > 9.0 g/dl
• absolute neutrophil count (ANC) > 1,000/mm3
• Platelet count > 75,000/mm3
• Total bilirubin < 1.5 x upper limit of normal (ULN)
• Alanine transaminase (ALT) and aspartate aminotransferase (AST) < 2.5 x the ULN (< 5 x ULN for patients with liver involvement). international normalized ratio (INR) < 1.5 or a Prothrombin time (PT)/partial thromboplastin time (PTT) within normal limits. Patients receiving anti-coagulation treatment with an agent such as warfarin or heparin may be allowed to participate.
• Creatinine < 1.5 x ULN
• Transfusions and the use of growth factors (for red and white cells) are allowed
• Patients must have received either docetaxel or mitoxantrone as the chemotherapy regimen
• Ability to understand and willingness to sign a written informed consent. A signed informed consent must be obtained prior to any study specific procedures.
• Patients must have progressed while receiving systemic chemotherapy for AIPC. Patients could have progressed within 12 weeks of their last systemic chemotherapy administration. The definition of progression is defined as follows:
• 1-For patients who are receiving systemic chemotherapy (one criteria is sufficient):
• Increase in prostate-specific antigen (PSA) by 25% or more than the previous value. This should be repeated within 3 weeks (while patient is off chemotherapy) to confirm that the PSA did not decrease.
• For patients with visceral disease, radiographic evidence of progression by standard Response Evaluation Criteria in Solid Tumors (RECIST) criteria (regardless of the PSA value).
• For patients with bone only disease, progression on a whole body bone scan (2 or more new lesions) is sufficient to fulfill the definition of progressive disease, regardless of PSA value or the visceral disease status.
• 2-For patients who have received chemotherapy previously (Both criteria are needed):
• Not more than 12 weeks have elapsed since last chemotherapy administration
• Either biochemical progression (25% increase in PSA that is confirmed with a repeat analysis within 3 weeks), OR radiographic progression (RECIST criteria for visceral disease patients OR 2 or more lesions on a whole body bone scan)

You may not qualify if…

• Cardiac disease: Congestive heart failure > class II New York Heart Association 9NYHA). Patients must not have unstable angina or new onset angina or myocardial infarction within the past 6 months.
• Known brain metastasis. Patients with neurological symptoms must undergo a CT scan or MRI of brain to exclude brain metastasis.
• Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy. Patients with history of chronic and well controlled atrial fibrillation are allowed. Beta-blockers, calcium channel blockers, or digoxin are not considered anti-arrhythmics.
• Uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic pressure > 90 mmHg, despite optimal medical management.
• Sorafenib is contraindicated in patients with known severe hypersensitivity to sorafenib or any of the excipients.
• Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.
• Active clinically serious infection > Common Toxicity Criteria for Adverse Effects (CTCAE) Grade 2.
• Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months.
• Pulmonary hemorrhage/bleeding event > CTCAE Grade 2 within 4 weeks of first dose of study drug.
• Any other hemorrhage/bleeding event > CTCAE Grade 3 within 4 weeks of first dose of study drug.
• Serious non-healing wound, ulcer, or bone fracture.
• Evidence or history of bleeding diathesis or uncontrolled coagulopathy.
• Major surgery, open biopsy or significant traumatic injury within 4 weeks of first study drug.
• Use of St. John's Wort or rifampin (rifampicin).
• Known or suspected allergy to sorafenib or any agent given in the course of this trial.
• Any condition that impairs patient's ability to swallow whole pills.
