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.
NCT00001944
Tumor resistance to anti-cancer drugs is a major problem in cancer treatment. Studies have found that a protein (P-glycoprotein) on some cancer cells pumps chemotherapy drugs out of the cells, reducing treatment effectiveness. In laboratory tests, an experimental drug called XR9576, has blocked pumping by this protein. It is being used in this study to try to increase the amount of the anti-cancer drug vinorelbine, in cancer cells. Vinorelbine has been shown in several clinical trials to be effective against some advanced cancers, including breast, lung and ovarian, and is one of the drugs pumped out of tumor cells by P-glycoprotein. Patients with cancer 18 years and older may be eligible for this study. Candidates will be screened with tests that may include blood and urine tests, electrocardiogram, echocardiogram, CT scans, X-rays, and nuclear medicine studies. A tumor biopsy may be done for diagnostic or research purposes. Study participants will undergo tumor imaging with the radioactive drug Tc-99m Sestamibi. This drug accumulates in tumor cells and is eliminated from them in much the same way that some cancer drugs are eliminated from cells. The drug is injected into a vein and a series of pictures are taken with a gamma camera. After this baseline scan, patients will receive a dose of XR9576 and undergo a second scan 24 hours later. The scan will show whether XR9576 affects the accumulation and elimination of Sestamibi in tumor cells. This procedure may provide a way to monitor cancers for evidence of chemotherapy resistance and show if XR9576 can improve the effectiveness of therapy. At least 10 days after the baseline and XR9576 scans, patients will begin the first of 3 or more 21-day cycles of vinorelbine treatment. On days 1 and 8 of each cycle, patients will receive a 30-minute infusion of XR9576 intravenously (through a vein) followed by vinorelbine, infused over a 6- to 10-minute period. (In some patients, XR9576 will be administered before only one of the two vinorelbine dosages.) Physical examination, blood tests, and other procedures may be done periodically to monitor treatment.
NCT00001302
The clinical study entitled "A Phase I Study of Infusional Chemotherapy with the P-glycoprotein Antagonist PSC 833" seeks to determine the maximum tolerated dose for a proposed P-glycoprotein antagonist, PSC 833. PSC 833 is a cyclosporine analogue which is purportedly non-nephrotoxic and non-immunosuppressive. It has been shown in in-vitro studies to enhance chemosensitivity as well as cyclosporine and to be far better at increasing intracellular drug accumulation than the concentrations of verapamil which are clinically achievable. The purpose of this study is to define the maximum tolerated dose in combination with vinblastine, and to determine how the drug affects the pharmacokinetics of vinblastine. PSC 833 will most likely reduce the clearance of vinblastine, as reported for the parent compound, cyclosporine. This effect will increase the area under the curve (AUC) of vinblastine, may increase toxicity, and requires that the escalation scheme for PSC 833 be a conservative one. Initially, a 120 hour infusion of vinblastine will be given alone. Then 8 days of PSC 833 will follow to allow monitoring of adverse effects of PSC 833 alone. This first cycle of vinblastine will be given in the absence of PSC 833; in second and subsequent cycles both agents will be combined. Escalation of the PSC 833 will continue until a target concentration is reached, or until the maximum tolerated dose is reached. Clinical responses will be monitored in order to provide the best possible medical care to our patients.
NCT00001444
This is a dosage escalation study to estimate the maximum tolerated dose of staurosporine analogue UCN-01. Groups of 3 to 6 patients receive a 72-hours intravenous continuous infusions of UCN-01 from day 1 to day 4 of each cycle the first cycle only, and over 36-hours on subsequent cycles. The side effects are allowed to disappear for up to 28 days. This cycle is repeated after evaluations and follow-ups, which are every 4 weeks, as long as the patient benefits.
NCT00001837
This research study is designed to work in cooperation with another study being conducted by the National Cancer Institute. The National Cancer Institute (NCI) is studying the effects of a drug called raloxifene on premenopausal women believed to have a high risk of developing breast cancer (98-C-0123). In this study, researchers are interested in learning about the effects of raloxifene on the uterus and ovaries of the women participating in the NCI study. To do this researchers plan to conduct ultrasounds on the patients enrolled in the NCI study. In addition researchers plan to take samples of the lining of the uterus in these patients (endometrial biopsy) if found to be necessary. The purpose of this study is to determine the reproductive effects of raloxifene on women who have normal functioning ovaries by taking ultrasounds of the ovaries and lining of the uterus (endometrium).
NCT00339248
This study will analyze blood samples to identify substances that are associated with the development of breast cancer. It will determine if: * Women who are diagnosed with a benign breast condition that is related to a considerably increased risk of breast cancer are more likely to have certain gene variants than women diagnosed with conditions related to very little increased breast cancer risk * Women with benign breast conditions who subsequently develop breast cancer are more likely to have certain gene variants than women with similar benign conditions who do not develop breast cancer. This study will examine blood samples from premenopausal women who underwent breast biopsy (removal of a small piece of breast tissue for microscopic examination) at four hospitals in Grand Rapids, MI, from 1977 to 1987 and were found to have benign breast disease. The women, who agreed to participate in a study of markers for breast cancer, also provided a blood sample and were interviewed for information on their breast cancer risk factors, family history of breast cancer, use of medications, and history of medical conditions. This study will retrieve the biopsy reports for these women, determine which of them later developed breast cancer, and perform genotyping on their blood samples. The information from this study may help in future diagnosis and treatment of breast cancer.
NCT00093002
The purpose of this study is to evaluate fulvestrant in the preliminary stage of breast cancer treatment and assess the relationship between dose, exposure, degree of reduction in tumor markers, and efficacy in postmenopausal women with estrogen receptor positive disease.
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.
NCT00097383
This is a non-randomized Phase 2 portion of a study testing ALIMTA and epirubicin in combination for locally advanced or metastatic breast cancer. Epirubicin is a well-established drug for the therapy of breast cancer. Both ALIMTA and epirubicin have been combined with other drugs but they have not yet been combined with each other. It is expected that the patient will benefit from the different mechanisms of action of the two drugs.
NCT00102219
This is a non-randomized Phase 2 study testing pemetrexed and doxorubicin in combination for locally advanced or metastatic breast cancer. Both pemetrexed and doxorubicin have been combined with other drugs, but they have not yet been combined with each other. It is expected that the patient will benefit from the different mechanisms of action of the two drugs. However, there is no guarantee that the patient will benefit from this treatment.
