Primary Outcome Measures:
  • to determine the maximum tolerated dose and dose limiting toxicity of docetaxel in the two treatment schedules [ Time Frame: every 2 weeks for up to 3 cycles ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • to determine the recommended docetaxel dose when combined with zoledronic acid for phase II studies [ Time Frame: every 2 weeks for 6 cycles ] [ Designated as safety issue: Yes ]
  • to determine which administration sequence of the combination permits a higher dosage of docetaxel [ Time Frame: every 2 weeks for 6 weeks ] [ Designated as safety issue: Yes ]
  • to describe the toxicity of the combination of the two drugs [ Time Frame: every 2 weeks ] [ Designated as safety issue: Yes ]
  • to describe the effects of the combination of the two drugs on biologic parameters: angiogenetic factors, cytokines, differential neuroendocrine markers, serum markers of osteolysis [ Time Frame: every 12 weeks ] [ Designated as safety issue: No ]
  • to describe the antitumor activity of the two drug association [ Time Frame: every 12 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 36
Study Start Date: July 2006
Study Completion Date: July 2009
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: docetaxel
    given IV in subsequent cohorts of patients at 30, 40, or 50mg/m2
    Drug: zoledronic acid
    2 mg IV every 2 weeks
Detailed Description:

Docetaxel has been used alone and in combination with other anti-cancer therapies in the treatment of hormone refractory metastatic prostate cancer. Zoledronic acid has been used in the treatment of bone metastasis from prostate cancer. This is a study of the combination of these two agents. The Zante study will test a dose escalation of docetaxel in association with a predetermined dose of zoledronic acid (2 mg), given every 14 days for a minimum of 6 and maximum of 12 cycles.

Sequence A: Docetaxel on day 1 and zoledronic acid on day 2

Sequence B: Zoledronic acid on day 1 and docetaxel on day 2

Patients are enrolled sequentially in cohorts of 3 for each dose level, and a maximum of 36 patients will be enrolled.
