简要总结
In this Phase I study safety of the combination of Docetaxel and Temsirolimus needs to be shown before the study can be expanded into a Phase II study to examine the activity of a safe combination of Temsirolimus and Docetaxel in a comparison with Docetaxel alone.
详细描述
The purpose of this Phase I study is to evaluate feasibility of dose levels DL1, DL2 and DL3 (which are combinations of Temsirolimus and Docetaxel) and defining a recommended dose (RD) for the Phase II part using these dose levels in a dose escalating scheme.
Secondary objectives are the collection of safety data on the dose levels used in this part.

入选标准
- •Phase I Part:
- •Adult males ≥18 years of age.
- •Patients with CRPC defined as confirmed rise of PSA levels after orchiectomy or LHRH agonist based therapy.
- •Progressive disease, defined as PSA progression by confirmed rising PSA levels.
- •PSA at time of study entry ≥2ng/ml within 1 week prior to treatment (according to Scher 2008).
- •Bone metastasis and/or lymph node and/or visceral organ metastases allowed. Measurable and non measurable disease allowed.
- •Performance status (PS) 0-1 ECOG.
- •Signed written informed consent.
- •White blood cell count (WBC) ≥4x10^9/L with neutrophils ≥1.5x10^9/L, platelet count ≥100x10^9/L, hemoglobin ≥9g/dL.
- •Total bilirubin <=2 x upper limit of normal.
- •AST and ALT <=2.5 x upper limit of normal, or <=5 x upper limit of normal in case of liver metastases.
- •Serum creatinine <=1.5 x upper limit of normal or creatinine clearance > 60 ml/min.
- •Androgen ablation will have to be continued. Antiandrogens such as bicalutamide will have to be discontinued at least 4 weeks prior to the start of study treatment.
排除标准
- •Phase I Part:
- •Clinically symptomatic brain or meningeal metastasis.
- •Receiving known strong CYP3A4 isoenzyme inhibitors and/or inducers.

- •Nonhealing wound or ulcer.
- •Grade ≥ 3 hemorrhage within the past month.
- •Any condition / concomitant disease not allowing chemotherapy with docetaxel, prednisone and temsirolimus in the discretion of the treating physician, like: Renal insufficiency requiring dialyses; congestive heart failure or uncontrolled angina pectoris; prior myocardial infarction within 6 months of start of chemotherapy; uncontrolled severe hypertension (failure of diastolic blood pressure to fall below 90 mm Hg despite the use of ≥ 3 anti-hypertensive drugs) or arrhythmias; instable diabetes mellitus, ulceration from diabetes mellitus or other conditions not allowing high dose corticosteroids; effusions in pericardium, pleura or abdomen symptomatic and in need of being punctured.
- •Known hypersensitivity to any of the components in the temsirolimus infusion or other medical reasons for not being able to receive adequate premedication (antihistamine agents).
- •Legal incapacity or limited legal capacity
- •Medical or psychological conditions that would not permit the patient to
- •complete the study or sign informed consent.
