Active clinical trials for "Breast Neoplasms"

A published phase 2 study reported that lonafarnib was administered as a single agent via continuous or intermittent oral dosing to 76 women with advanced breast cancer who were previously treated with chemotherapy and/or with endocrine therapy. Objective response rates of approximately 10% were observed. This study will determine the rate of progression-free survival of patients with metastatic breast cancer who receive lonafarnib.

Hormone receptor positive breast cancer is the most common type of breast cancer, comprising 70-80% of all breast cancers. Endocrine therapy is the main type of initial treatment for patients with your type of breast cancer. Endocrine therapy is treatment that tries to remove, or block certain hormones from binding to the cancer cells and thus slow or stop the growth of cancer. Although most patients with your type of breast cancer respond initially to endocrine therapies, it can lose its effectiveness. New therapies for this type of cancer are needed.

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. Dietary supplements, such as phytochemicals, may stop or delay the development of breast cancer. It is not yet known whether giving docetaxel together with a phytochemical is more effective than giving docetaxel alone in treating patients with breast cancer. PURPOSE: This randomized phase II trial is studying how well giving docetaxel together with a phytochemical works compared with giving docetaxel alone as first- or second-line therapy in treating patients with breast cancer.

This single arm study will evaluate the correlation between circulating endothelial cell levels and treatment efficacy in patients with locally recurrent and metastatic breast cancer given first line treatment with Avastin in combination with docetaxel + Xeloda.Patients will be treated with docetaxel 60mg/m2 iv on day 1, and Xeloda 900mg/m2 po on days 1-14, of each 3 week cycle, plus Avastin 7.5 mg/kg iv on day 1 of each 3 week cycle. The anticipated time on study treatment is until disease progression, and the target sample size is <100 individuals.

The purpose of this research study is to study the effects of using aromatase inhibitor (AI) therapy intermittently on participants with breast cancer. AIs are a class of drugs used to treat breast cancer in postmenopausal women. They work by decreasing the level of estrogen, which is believed to stimulate the growth of tumor tissue. Breast cancer that progresses despite therapy with an AI is thought to have become resistant to AI therapy. There is scientific evidence to suggest that resistant breast cancer cells learn to grow at the very low levels of estrogen present on AI therapy, and that increasing estrogen levels even slightly by stopping AI therapy may inhibit the breast cancer cells.

Women with hormone-receptor positive breast cancer are typically treated with hormone therapy as part of their treatment after surgery. In the past few years it has been found that treatment with aromatase inhibitors is superior to tamoxifen in postmenopausal women. Tamoxifen is still used for premenopausal women, however, because aromatase inhibitors are not effective in women who have functioning ovaries. Some women are premenopausal at the time they are diagnosed with breast cancer, but then stop having menstrual periods when they are treated with chemotherapy. It is unclear if these women can also be treated safely with aromatase inhibitors. In this clinical trial the researchers will try to answer this question. Women with hormone receptor positive breast cancer who become postmenopausal with chemotherapy will be invited to participate in this study. Each woman will be treated with one of the aromatase inhibitors, anastrozole (Arimidex), and then carefully monitored to ensure that her ovaries do not start making estrogen. If her estrogen level remains low, then she will continued to be followed for 18 months. If the level increases to the level typically seen in premenopausal women, however, then she will stop taking part in this study. The study will also evaluate multiple factors that may help doctors predict who will tolerate the therapy without having their ovaries start making estrogen again. Some of the factors to be evaluated include other hormone levels (blood tests) as well as family history of early menopause (mother, sisters). In addition, changes in certain genes that affect how patients' bodies handle chemotherapy drugs will be tested to see if they affect whether or not patients recover ovarian function. Overall, the purpose of the study is to determine which patients who become postmenopausal from chemotherapy are likely to tolerate aromatase inhibitor treatment safely, and how often the patients' ovarian function needs to be tested during treatment.

The purpose of this study is to determine efficacy and safety of paclitaxel, bevacizumab and enzastaurin versus paclitaxel, bevacizumab, and placebo in participants who are diagnosed with locally recurrent or metastatic breast cancer.

This randomized phase III trial studies first-line chemotherapy and trastuzumab to compare how well they work when given with or without bevacizumab in treating patients with breast cancer that overexpresses human epidermal growth factor receptor 2 (HER-2/NEU) and has spread to other areas of the body. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as trastuzumab and bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of breast cancer by blocking the growth of new blood vessels necessary for tumor growth. It is not yet known whether giving first-line chemotherapy together with trastuzumab is more effective with or without bevacizumab in treating patients with metastatic breast cancer that overexpresses HER-2/NEU.

RATIONALE: Drugs used in chemotherapy, such as liposomal doxorubicin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving them before surgery may kill more tumor cells. PURPOSE: This phase II trial is studying the side effects of giving liposomal doxorubicin together with docetaxel before surgery and to see how well it works in treating women with locally advanced breast cancer that can be removed by surgery.

To determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLTs) of ABI-008 giver every 3 weeks; to characterize the toxicities of ABI-008; and to determine the pharmacokinetic parameters for ABI-008 when given on an every-3-week schedule to patients with metastatic breast cancer.
