Safety and Efficacy Study of of Docetaxel vs Docetaxel Estramustine in Hormone Refractory Prostatic Cancer
Randomized Phase Ii Trial Of Weekly Docetaxel, Estramustine And Prednisone Versus Docetaxel And Prednisone In Patient With Hormone-Resistant Prostate Cancer

Detailed Description
The addition of estramustine to other chemotherapeutic agents that affect microtubule function may improve their efficacy15, 16, 17, 18. A phase III trial compared vinblastine versus the combination of vinblastine plus estramustine as treatment for patients with hormone-refractory prostate cancer. They showed that the association of estramustine and vinblastine was superior to vinblastine alone for time to progression, PSA response and survival (Hudes et al., ASCO 2002). In addition, Berry et al. found that estramustine/paclitaxel improved PSA response rate but not overall survival compared with paclitaxel alone (Berry et al. ASCO2001).
Similar association has been studied with docetaxel. In a phase I trial combining docetaxel and estramustine19, 53% of patients reported a decrease in narcotic use and 63% experienced a PSA response. In another phase I trial, a reduction in PSA of 50% or more was observed in 14 of 17 patients (82%)20. In a phase II trial involving 35 patients, a PSA response was reported in 74% of the patients and objective response in 4 out of 7 patients with measurable disease21. Median survival 22 months in this last study. These studies as well as other support the combination of estramustine and docetaxel in the treatment of HRPC22, 23.
Recently, Oudard et al. competed a phase II randomized study comparing mitoxantrone/prednisone versus docetaxel/estramustine prednisone24. Docetaxel was given either weekly or every 3 weeks. Association of docetaxel/estramustine was found superior to mitoxantrone in term of PSA response, (67-63% versus 18%), clinical benefit (79-56% versus 41%) and survival (19.2 months versus 11.6 months). In addition, toxicities of these regimens were manageable and predictable. In this study, patients received 2 mgr of coumadin to prevent thromboembolic event due to estramustine and only 7 % of the patients had thrombosis. Other grade III & IV toxicities of the estramustine/docetaxel combination included neutropenia (37% in the 3-week regimen and 0 % in the weekly regimen) nausea/vomiting (2% in the 3-week regimen and 0 % in the weekly regimen), diarrhea (7% in the 3-week regimen and 0 % in the weekly regimen). No febrile neutropenia was observed.
Although these data support a role for chemotherapy combinations, such as estramustine and docetaxel, in the treatment of HRPC, further studies are needed to determine the relative contribution of estramustine to the efficacy of docetaxel/estramustine regimen. In this context, we propose to randomize patients with hormone resistant prostate cancer between docetaxel/estramustine/prednisone and docetaxel/prednisone in a phase II study. The principal endpoint will be the efficacy in term of PSA response. We chose to use the weekly regimen as described by Oudard since the toxicity of this regimen is well described and is easily manageable in our experience.
