NCT00002564
RATIONALE: Dietary fat may be involved in the growth of cancer cells. Restricting dietary fat may help fight cancer. PURPOSE: Randomized clinical trial to study the effectiveness of a low fat diet in treating postmenopausal women who have stage I, stage II, or stage IIIA breast cancer that has been completely removed by surgery.
NCT00015938
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combining docetaxel, vinorelbine, and filgrastim in treating women who have stage IV breast cancer.
NCT00016406
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether combination chemotherapy is more effective with or without filgrastim in treating breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combining doxorubicin, cyclophosphamide, and paclitaxel with or without filgrastim in treating women who have inflammatory or locally advanced breast cancer.
NCT00002920
RATIONALE: It is not yet known whether medroxyprogesterone is effective in preventing endometrial disorder in patients with breast cancer who are taking tamoxifen. PURPOSE: Randomized phase III trial to study the effectiveness of medroxyprogesterone in preventing endometrial disorder in postmenopausal women who have ductal carcinoma in situ, lobular carcinoma in situ, Paget's disease of the nipple, stage I breast cancer, or stage II breast cancer and who are taking tamoxifen.
NCT00031811
RATIONALE: Raloxifene and exercise may improve bone health and quality of life in breast cancer survivors. Assessing bone health and quality of life may improve the ability to plan treatment. PURPOSE: Randomized clinical trial to study the effectiveness of raloxifene with or without exercise compared with exercise alone in women who have been previously treated for breast cancer.
NCT00657137
This study will compare the anti-tumor efficacy of apricoxib and lapatinib/capecitabine with placebo and lapatinib/capecitabine as measured by time to disease progression and evaluate urinary PGE-M measurements or baseline COX-2 expression in tumor tissue by IHC as a surrogate selection criterion for patients who will benefit from future treatment with apricoxib.
NCT00002646
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Combining chemotherapy with hormone therapy may kill more tumor cells. Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of fenretinide may be an effective way to prevent the recurrence of breast cancer. It is not yet known whether tamoxifen plus fenretinide is more effective than tamoxifen alone for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen plus fenretinide with tamoxifen alone in treating postmenopausal women who have stage II or stage III breast cancer that is estrogen receptor positive and/or progesterone receptor positive.
NCT00036621
This clinical trial will assess whether BMS-275291 can be administered safely in combination with standard adjuvant therapy for early breast cancer and whether plasma concentrations at trough exceed a target minimum.
NCT00002707
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if chemotherapy given before surgery is more effective with or without docetaxel given before or after surgery for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy using doxorubicin and cyclophosphamide with or without docetaxel in treating women who have stage II or stage III breast cancer.
NCT00540358
The purpose of this clinical trial was to determine whether combining iniparib (BSI-201) with standard chemotherapy in estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancer patients improve clinical benefit compared to treatment with standard chemotherapy alone. Based on data generated by BiPar/Sanofi, it was concluded that iniparib does not possess characteristics typical of the poly (ADP-ribose) polymerase (PARP) inhibitor class. The exact mechanism has not yet been fully elucidated, however based on experiments on tumor cells performed in the laboratory, iniparib is a novel investigational anti-cancer agent that induces gamma-H2AX (a marker of DNA damage) in tumor cell lines, induces cell cycle arrest in the G2/M phase in tumor cell lines, and potentiates the cell cycle effects of DNA damaging modalities in tumor cell lines. Investigations into potential targets of iniparib and its metabolites are ongoing.
NCT00465725
Picoplatin is a new platinum-based chemotherapy drug that has been studied in a variety of cancers. Phase 1 and 2 studies have demonstrated that picoplatin may be effective in patients whose cancer returns or does not improve after treatment with chemotherapy. In these studies, picoplatin was administered intravenously. A capsule containing picoplatin has been formulated. This study will investigate the activity of the oral capsule in humans. Participants with advanced solid tumors will be enrolled.
NCT00083304
RSR13 (efaproxiral) is a radiation sensitizer that has shown positive results in a Phase 3, randomized clinical trial of patients with brain metastases. Of 111 eligible breast cancer patients with brain metastases in that trial, 59 patients who received RSR13 prior to radiation therapy had a median survival time that was twice as long as the 52 patients who did not receive RSR13 prior to radiation therapy. RSR13 (efaproxiral) is an experimental drug that increases the amount of oxygen released from blood into the tissues. It is well known that certain types of cancer tumors, including those in brain metastases, lack oxygen. Lack of oxygen in a tumor can reduce the effect of radiation therapy (RT). RSR13 may increase the oxygen level in brain tumors so that radiation therapy works better. This study will enroll up to 360 women with brain metastases from breast cancer, and will evaluate if whole brain radiation therapy given with RSR13 will have a better treatment effect than whole brain radiation therapy alone. RSR13 will be infused intravenously (IV) through a central catheter placed in a central vein. Women randomized (assigned) to receive RSR13, therefore, will need to have a central catheter placed for treatment unless one is already in place.
NCT00063570
The purpose of the study is to determine if the two drugs can help patients feel better while causing the tumor to become smaller or disappear; evaluate the safety of giving both pemetrexed and gemcitabine in patients with advanced breast cancer.
NCT00028405
This multi-center photodynamic therapy study plans to treat patients with large tumors in any superficial location, sarcoma, tumors of oral/oro-pharyngeal cavity, tumors with extensive pelvic involvement, or liver metastasis. The treatment is limited to patients that have failed to respond to currently approved methods of treatment. The study involves a single, intravenous administration of an investigational drug, LS11 (previously studied in approximately 80 cancer patients) and the placement of a novel, flexible light delivery catheter inside the tumor by a minor surgical procedure. The activation of LS11 by the light delivery catheter over a period of 1-24 hrs may result in destruction of tumor tissue.
NCT00081796
The purpose of this clinical trial is to determine if RPR109881 is a better treatment than capecitabine (Xeloda) for advanced breast cancer in patients that no longer benefit from docetaxel and/or paclitaxel.
NCT00022672
This 2 arm study assessed the safety and efficacy of adding intravenous trastuzumab (Herceptin®) to daily oral anastrozole (Arimidex®) tablets as first- and second-line treatment in postmenopausal patients with human epidermal growth factor receptor-2 (HER2) overexpressing metastatic breast cancer (ER+ve and/or PR+ve). Patients were randomized to receive either anastrazole 1 mg per os (po) daily, or anastrazole 1 mg po daily + a loading dose of Herceptin® 4 mg/kg intravenous (iv) followed by weekly doses of Herceptin® 2 mg/kg iv. The anticipated time on study treatment was until disease progression, and the target sample size was 100-500 individuals.
NCT01537406
The purpose of this study is to evaluate the frequency of chronic breast pain about 8 years after the delivery of the radiation treatment, and to compare the frequency between subjects that received breast Intensity-Modulated Radiation Therapy (IMRT) and those that received standard wedge radiotherapy. The cosmetic result, meaning how similar is the treated breast compared to the non-treated breast, will be assessed. Also, the occurrence of delayed radiation treatment side effects including tiny red vessels in the skin, breast indurations (hardening of the skin), skin discoloration, oedema (swelling of the breast), and skin dryness will be captured.
NCT00077857
This 2 arm study compared the efficacy and safety of label dose of capecitabine (Xeloda®) to that of a lower dose of Xeloda® plus docetaxel (Taxotere®) in patients with locally advanced or metastatic breast cancer after failure of chemotherapy with an anthracycline. Patients were randomized to receive either 1250 mg/m\^2 or 825 mg/m\^2 orally twice a day (po bid) on days 1-14 of each 3 week cycle, in combination with Taxotere® 75 mg/m2 intravenous (iv) on day 1 of each 3 week cycle. The anticipated time on study treatment was until disease progression and the target sample size was 440 individuals.
NCT00418236
It has been shown that women who have dense breasts have an increased risk of breast cancer compared with women whose breasts are less dense. However, while breast density may be a risk factor, the etiology of the relationship between breast cancer and breast density is not understood. Furthermore, it is well recognized that breast cancer can still develop in women whose breasts are not dense. At menopause, the amount of breast glandular tissue and stroma naturally decreases due to a lack of hormonal stimulation. This is characterized as a decrease in the mammographic density. Although certain medications, including hormone therapy (HT) and dopamine antagonists can increase breast density, these effects are reversible upon discontinuation of the specific agent. Other medications such as the selective estrogen receptor modulators (SERM), raloxifene (RAL) and tamoxifen, have been shown to not affect breast density and allow the normal age-related changes to occur. The effects of bazedoxifene (BZA), a new SERM, on breast density are not known. The purpose of this study is to examine the effect of BZA on breast density changes over 24 months in postmenopausal women. The results may be useful for clinicians to understand the effect of BZA on breast density and its mammographic effects. This is an observational, multicenter, double-blind, randomized, placebo- and active comparator-controlled study. It is also an ancillary that will use women who are already participants in a phase 3 trial for fracture reduction (protocol 3068A1-301-WW; primary study). In the primary study, subjects received BZA 20 mg, BZA 40 mg, RAL 60 mg, or placebo. This ancillary study will request a subset of participants to use their mammograms taken in this study. Their mammogram will be digitized by a central imaging center. A single radiologist will perform the quantifications of breast density from the digitized mammograms.
NCT00003992
Randomized phase II trial to study the effectiveness of chemotherapy with paclitaxel and the monoclonal antibody trastuzumab followed by chemotherapy in treating women who have stage II or stage IIIA breast cancer that overexpresses HER2. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may kill more tumor cells.
