Multicenter Study Comparing Taxotere Plus Curcumin Versus Taxotere Plus Placebo Combination in First-line Treatment of Prostate Cancer Metastatic Castration Resistant (CURTAXEL)

Overview

Multicenter randomized phase II study, double-blind, comparing Taxotere plus curcumin versus Taxotere plus placebo combination in first-line treatment of prostate cancer metastatic castration resistant. Assess time to progression (time to progression) of metastatic disease (from first day of treatment in the trial).

Clinical Trial Outcome Measures

Primary Measures

  • Time to progression
    • Time Frame: participants will be followed post treatment. From date of randomization until the date of first documented progression or date of death from any cause
    • Assess time to progression (time to progression) of metastatic disease (from first day of treatment in the trial). Progression was defined as an increase (of) injury (s) tumor (s) (RECIST) or an increase in PSA levels (≥ 25% and ≥ 2ng/ml increase) or the appearance of new lesions metastatic (at least 2 new lesions for bone lesions). From date of randomization until the date of first documented progression or date of death from any cause

Secondary Measures

  • PSA response
    • Time Frame: From date of randomization until the date of first documented PSA progression or date of death from any cause
    • Evaluate the PSA response (50% decrease compared to the initial value)
  • objective tumor response rate
    • Time Frame: participants will be evaluated at the end of the treatment (randomization + an expected average of 4 months)
    • Evaluate the objective tumor response rate (CR + PR) by RECIST.
  • safety and tolerability
    • Time Frame: patients will be followed for the duration of the treatment, an expected average of 4 months
    • Assess the safety (adverse events) of the combination Taxotere/ curcumin.
  • Pain
    • Time Frame: participants will be followed at Cycle1,3,6 of chemotherapy and post treatment (+1months after the end of the treatment)
    • Assess pain in the short questionnaire on pain (QCD)
  • neuroendocrine markers
    • Time Frame: participants will be followed for the duration of the treatment, an expected average of 4 months
    • Assess serum neuroendocrine markers
  • Overall survival
    • Time Frame: from date of randomization until the date of death from any cause
    • Evaluate overall survival (between inclusion and death whatever the cause)
  • anti-angiogenic activity
    • Time Frame: participants will be followed at each Cycle of chemotherapy ( + inclusion) , an expected average of 4 months
    • Evaluate the anti-angiogenic activity of the association Taxotere ® plus curcumin
  • compliance
    • Time Frame: patients will be followed for the duration of the treatment, an expected average of 4 months
    • Assess the compliance by curcumin treatment / placebo orally
