Phase III Randomized Trial of Hormone Therapy with TMX vs MEG vs TMX plus MEG in Patients with Advanced Breast Cancer
Basic Trial Information
Objectives I. Establish the relative response rate produced by tamoxifen vs. megace vs. tamoxifen plus megace in patients with advanced breast cancer. Entry Criteria Disease Characteristics: See General Eligibility Criteria Patient Characteristics: See General Eligibility Criteria General Eligibility Criteria: Patients with advanced breast cancer who are estrogen receptor status unknown or who are estrogen receptor positive or progesterone receptor positive. There may have been no prior hormone treatment, and patients must have a demonstrable lesion that can be either measured or evaluated over time. Expected Enrollment Approximately 100 patients will be accrued. Outline Randomized study. Patients are initially randomized to Arms I, II, and III; subsequent therapy on Regimen A or B is determined by response and menopausal status. Arm I: Single-agent Hormonal Therapy. Tamoxifen, TMX, NSC-180973. Arm II: Single-agent Hormonal Therapy. Megace, Megestrol acetate, MEG, NSC-71423. Arm III: 2-Drug Combination Hormonal Therapy. TMX; MEG. Regimen A: Single-agent Hormonal Therapy. Aminoglutethimide, AGT. Regimen B: 2-Drug Combination Hormonal Therapy. AGT; Ethinyl Estradiol, Estinyl, NSC-10973.

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. |
