Phase III Randomized Comparison of Leuprolide/Anandron vs Leuprolide/Placebo in Patients with Stage D2 Carcinoma of the Prostate
Basic Trial Information
Objectives I. Compare, in a double-blind randomized Phase III trial, the therapeutic efficacy and tolerance of leuprolide/anandron vs. leuprolide/placebo in patients with Stage D2 prostatic carcinoma. II. Determine and compare time to progression, survival, clinical response, pain, and performance in the two treatment groups. III. Evaluate the long-term safety of anandron in this patient population. Entry Criteria Disease Characteristics: See General Eligibility Criteria Patient Characteristics: See General Eligibility Criteria General Eligibility Criteria: Patients aged 40 to 85 years who present with newly diagnosed, histologically confirmed Stage D2 carcinoma of the prostate and who are willing to accept treatment with leuprolide. Patients must not have received previous systemic chemotherapy or endocrine therapy, including hormonal therapy, orchiectomy, hypophysectomy, and adrenalectomy. They may have been treated by prostatectomy for initially diagnosed localized prostate cancer, and they may have received previous radiotherapy of the primary tumor provided there are evaluable sites of active disease outside the radiotherapy ports. There must be no rapidly progressing life-threatening illness other than carcinoma of the prostate, and the minimum life expectancy is 3 months. Patients with another neoplasm, aside from nonmelanomatous skin cancer, are excluded. There may be no sensitivity to any contrast agent used in radiologic evaluation, and patients must not have other medical conditions or a requirement for a medication that might interfere with interpretation of efficacy or tolerance. Liver and kidney function must be adequate as evidenced by the following: serum bilirubin not greater than 2.0 mg/dl and transaminases not more than 3 times the upper limit of normal, except in the presence of hepatic metastases; BUN not over 40 mg/dl and serum creatinine not over 2.0 mg/dl, unless solely related to the prostatic tumor. Expected Enrollment 200 patients will be entered on each arm over about 9 months. Outline Double-blind, randomized study. Arm I: Endocrine Therapy. Releasing Factor Agonist plus Antiandrogen. Leuprolide, LEUP, NSC-377526; plus RU 23908, Anandron, ANAN. Arm II: Endocrine Therapy. Releasing Factor Agonist plus Placebo. LEUP; plus Placebo.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. |
