- Conditions

- Registration Number
- NCT01254513
- Lead Sponsor
- UNICANCER
- Brief Summary
The objective of this study is to evaluate the feasibility of two different chemotherapy protocols with adjusted doses for patients aged 75 and over who often have medical problems other than prostate cancer. Patient will receive Docetaxel either every 3 weeks or weekly. In both cases, chemotherapy is combined with prednisone. The protocol will be considered feasible when patient will receive 6 cycles of chemotherapy (1 cycle = 3 weeks).
Additionally to this primary objective, efficacy will also be evaluated for both protocols as well as tolerance to treatment, quality of life and evolution of geriatric data.
- Detailed Description
Standard management of castration-resistant metastatic prostate cancer is represented by chemotherapy with Docetaxel 75 mg/m² every 3 weeks combined with Prednisone since a symptomatic and overall survival benefit was demonstrated.
Although this benefit is independent of age in the study by Tannock (cut-off:69), it does not seem possible to extrapolate these results, obtained in a selected population, to the majority of patients we encounter in daily practice, \>= 75 years old and / or unfit.
Retrospective studies have shown that chemotherapy was feasible, at standard or adapted doses in an unselected elderly population with good results in terms of tolerance and efficacy over symptoms.
Our study aims to evaluate prospectively the feasibility of a chemotherapy with Docetaxel/Prednisone administered every 3 weeks (60 mg / m² at D1C1 then 70 mg / m² at D1 for subsequent cycles if tolerance is good) or weekly (35mg / m² at D1 and D8 with Day 1 = Day 21) to patients \>= 75 years old, evaluated by comprehensive geriatric assessment, belonging to group 2 "vulnerable" or to group 3 "frail" of the classification proposed by the International Society of Geriatric Oncology (SIOG).
Feasibility is defined as the possibility for a patient to receive 6 cycles of chemotherapy without withdrawal. Reasons for study withdrawal were defined by the GERICO Group and are the followings:
* stop or delay of chemotherapy \> 2 weeks
* Necessity to reduce the dose of chemotherapy \> 25 %
* febrile neutropenia or non-haematological grade 3 toxicity (except alopecia) according to NCI-CTCAE V4.0.
* Geriatric criterion (Activity of Daily Living (ADL) decrease \>= 2 points)
The statistical methodology used is a double randomized phase II after stratification according to the SIOG criteria, based on a Simon Optimum plan.
A pharmacokinetic / pharmacodynamic study is associated to our project, based on a method of population pharmacokinetic. The aim is to highlight predictors of the haematological tolerance of this chemotherapy by evaluating clinical, geriatric and biological parameters.
The results of this study will support the terms of prescription of chemotherapy, in patients aged 75 and over, classified as "vulnerable" or "frail" regarding SIOG criteria, with defined geriatric assessment.

- For patients treated with anti-androgens prior to inclusion, a wash-out period is required (4 weeks for flutamide and nilutamide, 6 weeks for other products) as well as measured progression after anti-androgen discontinuation.
-
Progressive disease under hormonotherapy, with progression defined by
Increase of PSA level (two consecutive increases of PSA compared to baseline with a minimum of one week between both measurements)
OR emergence of a new lesion
OR measurable progressive disease (increase of a previous measurable lesion >= 25% in cross section)
OR progressive bone metastases (defined only by the appearance of a new lesion on bone scan)
OR progressive symptoms (defined as cancer pain Grade 2 according to the NCI-CTC V4.0, despite level 2 analgesics intake).
