ZD 1839 in Treating Patients With Prostate Cancer That Has Not Responded to Hormone Therapy
- Conditions
- Prostate Cancer
- Registration Number
- NCT00025116
- Lead Sponsor
- NCIC Clinical Trials Group
- Brief Summary
RATIONALE: Biological therapies such as ZD 1839 may interfere with the growth of tumor cells and slow the growth of prostate cancer. It is not yet known which dose of ZD 1839 is more effective in treating prostate cancer that has not responded to hormone therapy.
PURPOSE: Randomized phase II trial to compare different doses of ZD 1839 in treating patients who have prostate cancer that has not responded to hormone therapy.
- Detailed Description
OBJECTIVES:
* Compare the efficacy of 2 different doses of ZD 1839, in terms of objective response, PSA response, and duration of response, in patients with hormone-refractory adenocarcinoma of the prostate.
* Compare the tolerability and quantitative toxicity of these regimens in these patients.
* Determine whether there is an association between any response or stable disease and clinical benefit as assessed by changes in quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to measurable disease (yes vs no). Patients are randomized to 1 of 2 treatment arms.
* Arm I: Patients receive oral, low-dose ZD 1839 twice daily on day 1 and once daily on days 2-28 during course 1 and then once daily on days 1-28 during subsequent courses.
* Arm II: Patients receive oral, high-dose ZD 1839 as in arm I. Treatment in both arms continues every 4 weeks in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, at the end of each course during study, and then at 4 weeks after study.
Patients with stable or responding disease are followed at 4 weeks and then every 3 months until disease progression. All other patients are followed at 4 weeks only.
PROJECTED ACCRUAL: A total of 30-60 patients (15-30 per treatment arm) will be accrued for this study.
