Arms	Assigned Interventions
1: Active Comparator docetaxel 75mg/m2 day1 q 21d x 4 cycles, sunitinib 37.5mg/d day2 -day15 x 4 cycles	Drug: Docetaxel * Sunitinib docetaxel 75mg/m2 day1 q 21d x 4 cycles, sunitinib 37.5mg/d day2 -day15 x 4 cycles
2: Active Comparator docetaxel 75mg/m2 day1 q 21d x 4 cycles	Drug: Docetaxel docetaxel 75mg/m2 day1 q 21d x 4 cycles

Detailed Description:

Docetaxel (75mg/m2 q21d) is standard of care for patients with hormone refractory prostate cancer (HRPC). Recent data indicate, that chemotherapeutics given at MTD induce, besides their cytotoxic effects, mobilization of circulating endothelial cells (CEC) and - progenitors (CEP) in drug-free breaks of each cycle. In preclinical models, mobilized CEC/CEP result in tumor vasculogenesis and progression of disease.

We hypothesize that treatment with sunitinib, an anti-angiogenic tyrosine kinase inhibitor, in between 3 weekly docetaxel disrupts CEC/CEP spikes following docetaxel leading to chemosensitization and reduced tumor re-growth in HRPC patients responding to docetaxel.
