Primaire uitkomstmaten
Progression free survival. Progression is defined according to the recommendations of the Prostate Cancer Clinical Trials Working Group (Scher et al, JCO 2008, 26(7), 1148-59)
Achtergrond van het onderzoek
Prostate cancer is very common and often leads to bone metastases. Although initially most patients respond to androgen deprivation, after approximately 18 months the cancer will become hormone refractory leading to progressive disease. Since 2004 docetaxel became standard chemotherapy for men with metastatic CRPC leading to survival benefit. Several trials have shown evidence of the disease modifying potential of bone seeking radionuclides. Recent studies have shown an improvement of survival and quality of life when Rhenium-186 HEDP was given in high dosage or repeatedly. Recently results of our dose finding trial (XRP6976J/6213) shows that combined therapy with docetaxel and Rhenium-186 HEDP is generally well tolerated in patients with metastatic bone disease from prostate cancer. A phase II study (DOCET_L_04935) will be conducted using 3 cycles of docetaxel 75mg/m2 followed by Rhenium-188 HEDP , followed by another 3 cycles of docetaxel, followed by Rhenium-188 HEDP. Cabazitaxel is a promising new drug to be used for the treatment of metastatic castrate resistant prostate cancer (mCRPC) after progression on docetaxel therapy.
In this study, we build upon previous results and we aim to test whether the combination of cabazitaxel with repeated Rhenium-188 HEDP is feasible and leads to better PFS, OS and pain control compared to cabazitaxel alone in patients with mCRPC after progression of disease after first line docetaxel. We start with a phase I dose finding trial, immediately followed by a phase II trial if the envisaged schedule is feasible.

Onderzoeksopzet
The study will take about 2 years starting approximately at 01-02-2012.
Onderzoeksproduct en/of interventie
In the phase I part patients will recieve Rhenium-188 HEDP in combination with a dose finding schedule of Cabazitaxel (20 mg/m2 or 25 mg/m2). The feasible combination will be used in the following randomized phase II part of the study. Patients will be randomised between treatment with Cabazitaxel monotherapie or combination therapy with Cabazitaxel and Rhenium-188 HEDP.
