E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective in the Phase I Part is to evaluate feasibility of dose level DL1 to DL3 and defining a recommended dose (RD) for the Phase II part using the dose levels DL1-DL3 of the phase I part.
The primary objective in the study’s Phase II Part is to evaluate the activity of the addition of temsirolimus to standard treatment on the disease progression-free survival in patients with castration resistant prostate cancer receiving first-line docetaxel chemotherapy. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives in Phase I Part are the collection of safety data on the dose levels used in this part.
Secondary objectives /endpoints of Phase II Part are the characterization of:
overall response through the overall response rate, RR,
disease control rate, CR+PR+SD,
tolerability/safety,
overall survival (OSChemotherapy),
quality of life (QoL).

E.4 | Principal exclusion criteria |
1.Prior Chemotherapy including estramustine (prior treatment is allowed in Phase I part)
2.Clinically symptomatic brain or meningeal metastasis
3.Receiving known strong CYP3A4 isoenzyme inhibitors and/or inducers
4.Any investigational drug within the 30 days before inclusion. Not recovered from prior biopsy, surgery, traumatic injury, and/or radiation therapy, as judged by the investigator
5.Nonhealing wound or ulcer
6.Grade ≥ 3 hemorrhage within the past month
7.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
8.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)
9.Legal incapacity or limited legal capacity
10.Medical or psychological conditions that would not permit the patient to complete the study or sign informed consent

E.5 End points |
E.5.1 | Primary end point(s) |
Phase I Part: Primary endpoint is the Recommended Dose (RD) for the Phase II Part chosen between the three DLs based on the dose escalation scheme.
Phase II Part: Disease Progression Free Survival assessed after 6 months quantified by the parameter DPFS-6mR, the 6-months Disease-Progression Free Survival Rate.
DPFS-6mR is defined as the quotient of the number of patients who are disease progression free over the number of patients who are evaluable with respect to DPFS-6mR.
