Brief Summary:

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Hydroxychloroquine may help docetaxel work better and kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving docetaxel together with hydroxychloroquine works in treating patients with metastatic prostate cancer.

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: docetaxel Drug: hydroxychloroquine Phase 2

Detailed Description:



  • To assess the antitumor activity, in terms of tumor response rate, of docetaxel in combination with hydroxychloroquine in patients with metastatic, hormone-refractory, chemotherapy-naive prostate cancer.


  • To measure time to disease progression and overall survival.
  • To determine the feasibility and safety of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive oral hydroxychloroquine twice daily on days 1-21 and docetaxel IV over 1 hour on day 1. Treatment repeats every 21 days (up to 6 courses with docetaxel) in the absence of disease progression or unacceptable toxicity.

MedlinePlus related topics: Prostate Cancer

Arm Intervention/treatment
Experimental: Docetaxel and Hydroxychloroquine

Drug: Docetaxel 75 mg/m2 intravenously every 21 days on Day 1 of the treatment cycle

Drug: hydroxychloroquine 200 mg twice daily

A cycle is defined as an interval of 21 days.

Drug: docetaxel
Drug: hydroxychloroquine

Primary Outcome Measures :
  1. Tumor Response Rate - Primary Endpoint is a 50% Decline in PSA or Normalization of PSA. [ Time Frame: 4 years ]
    We will use a two-stage optimal Simon's design with a 5% significance level and 80% power to detect an increase in response rate from 50% to 70%. The first stage will enroll 15 patients. If there are 8 or fewer responses among these 15 patients, we will consider the combination therapy to not be worthy of further study, and stop the trial. If we find 9 or more responses, we will proceed to the second stage, and accrual continues for a total of 43 patients. If we see 26 or fewer responses out of 43, then no further investigation of the drug is warranted. If we see 27 or more responses out of 43, then further investigation of the drug will be considered. The "expected" sample size of the trial is 23.5 with the null response rate of 50%.

Secondary Outcome Measures :
  1. Time to Disease Progression [ Time Frame: 10 years ]
  2. Overall Survival [ Time Frame: 10 years ]
