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).
