Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer Clinical Trials References presented on Clinical Trials Search isn't meant to be a substitute for proven healthcare advice, trips or professional assistance using a genuine physician. We are not docs. Always confer with your physician about Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer Clinical research trials and Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer healthcare trials happen in hundreds of localities throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the potency of new drugs. The propose of the studies / projects is to answer particular human health questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to detect cures for all sorts of conditions, such as Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer. Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer Clinical Trials and other clinical trials allow volunteers to acquire healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer clinical trial. Subjects frequently obtain the most expert healthcare possible for their Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer condition. Risks are a reality, nevertheless, and can include more or frequent doctor trips, medical risks (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with stern guidelines to protect clinical trials patients.

Letrozole With or Without CCI-779 in Treating Postmenopausal Women With Locally Advanced or Metastatic Breast Cancer
For Condition: recurrent breast cancer,stage 4 breast cancer,stage 3B breast cancer,stage 3C breast cancer
Status: Recruiting
Sponsor(s): Ireland Cancer Center , National Cancer Institute (NCI)
Synopsis: RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by blocking the uptake of estrogen. Drugs used in chemotherapy such as CCI-779 use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether letrozole is more effective with or without CCI-779 in treating patients with breast cancer. PURPOSE: Randomizedphase II trial to compare the effectiveness of letrozole with or without CCI-779 in treating postmenopausal women who have locally advanced or metastatic breast cancer.
Details: OBJECTIVES: - Compare the objective response rate of postmenopausal women with locally advanced or metastatic breast cancer treated with letrozole with vs without CCI-779. - Compare the overall response rate, including stable disease lasting at least 6 months, time to progression, and time to treatment failure, in patients treated with these regimens. - Compare the pharmacokinetics of these regimens in these patients. - Compare the safety of these regimens in these patients. - Correlate the pharmacodynamics of these regimens with clinical response in these patients. - Compare the impact of these regimens on patient-reported health outcomes. - Compare progression-free rates at various intervals in patients treated with these regimens. - Compare duration of response and overall survival of patients treated with these regimens. OUTLINE: This is an open-label, randomized, multicenter study. Patients are randomized to 1 of 3 treatment arms. - Arm I: Patients receive oral letrozole and oral CCI-779 daily. - Arm II: Patients receive oral letrozole on days 1-14 and oral CCI-779 on days 1-5. Courses repeat every 14 days. - Arm III: Patients receive oral letrozole daily on days 1-5. Courses repeat every 14 days. Patients with disease progression may cross over to oral CCI-779 alone on days 1-5 every 14 days. In all arms, treatment continues for up to 24 months in the absence of disease progression or unacceptable toxicity. Patients are followed at 30 days and then every 3 months thereafter. PROJECTED ACCRUAL: Approximately 108 patients (36 per treatment arm) will be accrued for this study.
