Docetaxel, Prednisone, and Pasireotide in Treating Patients With Metastatic Hormone-Resistant Prostate Cancer

Completed · Phase 1/Phase 2

Conditions studied: Adenocarcinoma of the Prostate, Hormone-resistant Prostate Cancer, Recurrent Prostate Cancer, Stage IV Prostate Cancer

In brief

This phase I/II trial studies the side effects and best dose of pasireotide and to see how well it works when given together with docetaxel and prednisone in treating patients with metastatic hormone-resistant prostate cancer. Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Pasireotide may inhibit the secretion of hormones. Giving pasireotide together with docetaxel and prednisone may kill more tumor cells.

You may qualify if…

• Histologically confirmed prostate adenocarcinoma with metastasis, and objective progression or rising PSA despite androgen deprivation therapy and antiandrogen withdrawal when applicable; patients with rising PSA must demonstrate a rising trend with 2 successive elevations at a minimum interval of 1 week; a minimum PSA of 5 ng/ml or new areas of bony metastases on bone scan are required for patients with no measurable disease; no minimum PSA requirement for patients with measurable disease
• Patient must not have received any prior chemotherapy for metastatic disease; all patients must be documented to be castrate with a testosterone level < 0.5 ng/ml; luteinizing hormone-releasing hormone (LHRH) agonist therapy must be continued, if required to maintain castrate levels of testosterone; patients must be off antiandrogens for a minimum of 4 weeks for flutamide and 6 weeks for bicalutamide or nilutamide
• Minimum of four weeks since any major surgery, completion of radiation, or completion of all prior systemic anticancer therapy (adequately recovered from the acute toxicities of any prior therapy)
• Eastern Cooperative Oncology Group (ECOG) performance status =< 2
• Life expectancy 12 weeks or more
• Absolute neutrophil (ANC) >= 1.5 x 10\^9/L
• Platelets >= 100 x 10\^9/L
• Hemoglobin (Hgb) > 9 g/dL
• Serum bilirubin =< 2 x upper limit of normal (ULN)
• Serum transaminases activity =< 3 x ULN, with the exception of serum transaminases (< 5 x ULN) if the patient has liver metastases
• Serum creatinine =< 1.5 x ULN
• Fasting serum cholesterol =< 300 mg/dL OR =< 7.75 mmol/L AND fasting triglycerides =< 2.5 x ULN; NOTE: in case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication
• Patients must be advised of the importance of using effective birth control measures during the course of the study
• Signed informed consent to participate in the study must be obtained from patients after they have been fully informed of the nature and potential risks by the investigator (or his/her designee) with the aid of written information

You may not qualify if…

• Prior treatment with any cytotoxic chemotherapy, radiation, immunotherapy, or any investigational drug within the preceding 4 weeks
• Patients who have undergone major surgery within 4 weeks prior to study enrollment
• Chronic treatment with immunosuppressive agents except steroids
• Patients should not receive immunization with attenuated live vaccines during study period or within 1 week of study entry
• Uncontrolled brain or leptomeningeal metastases, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases
• Patients with prior or concurrent malignancy except for the following: adequately treated basal cell or squamous cell skin cancer, or other adequately treated in situ cancer, or any other cancer from which the patient has been disease free for five years
• Patients with uncontrolled diabetes mellitus, which is defined as a hemoglobin A1C > 8% on therapy or > 7% without therapy, or a fasting plasma glucose > 1.5 ULN; Note: at the principle investigator's discretion, non-eligible patients can be re-screened after adequate medical therapy has been instituted
• Patients with symptomatic cholelithiasis
• Patients who have congestive heart failure (New York Heart Association [NYHA] Class III or IV), unstable angina, sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block or a history of acute myocardial infarction within the six months preceding enrollment
• QT-related exclusion criteria:
• Patients with baseline QTc > or = 470 msec
• History of syncope or family history of idiopathic sudden death
• Sustained or clinically significant cardiac arrhythmias
• Patients with risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia, cardiac failure, clinically significant/symptomatic bradycardia, or high-grade AV block
• Concomitant disease(s) that could prolong QT such as autonomic neuropathy (caused by diabetes or Parkinson's disease), human immunodeficiency virus (HIV), cirrhosis, uncontrolled hypothyroidism or cardiac failure
• Concomitant medication(s) known to prolong the QT interval
• Patients with the presence of active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result (enzyme-linked immunosorbent assay [ELISA] and Western blot)
• Patients who have any severe and/or uncontrolled medical conditions or other conditions that could affect their participation in the study such as:
• Severely impaired lung function
• Any active (acute or chronic) or uncontrolled infection/ disorders
• Nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with the study therapy
• Known hypersensitivity to somatostatin analogues or any component of the pasireotide or octreotide long-acting release (LAR) formulations
• History of noncompliance to medical regimens
• Patients unwilling to or unable to comply with the protocol
• Men and any female partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation and for additional 2 months after finishing therapy; should a patient's sexual partner become pregnant or suspect she is pregnant while patient is participating in this study, he should inform the treating physician immediately
