NCT00011804	Topiramate in the Treatment of Sciatica	Completed	National Institute of Dental and Craniofacial Research (NIDCR)	Phase 2	This study will test the effectiveness of topiramate to treat pain caused by lumbar radiculopathy, or sciatica. Sciatica results from damage to the lumbar nerve roots, typically causing back pain and sharp, shooting pain down one or both legs. Although sciatica is common, there are no good treatments for it. Topiramate belongs to a group of medications commonly used to treat pain caused by nerve damage. Patients between 18 and 75 years of age who have had sciatica pain daily for at least 3 months may be eligible for this study. (This is taken from the first paragraph of the Qualification Criteria in the consent form. The inclusion criteria on page 6 of the protocol say "low back pain of 3 months duration or longer present at least 5 out of 7 days a week" and signs and symptoms of lumbar radiculopathy. Which is correct?) Participants will provide a medical history, as well as occupational and social information. They will undergo a standard neurological examination, including a test of cognitive (thinking) abilities, muscular function, reflexes and a sensory examination. The latter involves testing with a pin placed on the surface of the skin. Participants will also have routine blood tests and will fill out questionnaires on their daily functioning and psychological well being. Additional procedures may include magnetic resonance imaging (MRI) scans and possible referral to a psychiatrist for evaluation of depression or emotional difficulties. This "cross-over" study consists of two parts. In one part, patients will receive topiramate and in the other, an active placebo. An active placebo is a drug that does not work for the problem being studied but whose side effects are like those of the test drug. Diphenhydramine (Benadryl) is the active placebo used in this study. Diphenhydramine is an allergy medication with very mild side effects, such as drowsiness. During both parts of the study-topiramate and placebo-patients will keep a daily log in which they rate their pain, record other procedures they undergo, such as injections and manipulations, and record medication side effects. In the first week of the study, patients will remain on their current medications and record pain levels once a day. After the first week, they will begin taking the study drugs-either topiramate in increasing doses ranging from 50 to 400 mg. or diphenhydramine in doses ranging from 6.25 to 50 mg. The drug doses will be increased gradually over 4 weeks to minimize possible side effects. Increases will continue until the maximum tolerated dose is reached. Patients will continue on the highest tolerated dose for two weeks and then be tapered off gradually over 12 days. They will remain off drugs completely for a 2-day washout period and then begin the next treatment. Those who took topiramate for the first part will take diphenhydramine for the second part and vice versa. A study nurse will call patients twice a week throughout the study to check for problems and answer questions. A physician will see patients 6 weeks after the start of each treatment. During the last visit, at the end of the study, patients will repeat the questionnaires they filled out at the beginning of the study. Patients and their doctors will be informed of the medications that were effective in each individual's care.
NCT00030992	BMS 247550 to Treat Kidney Cancer	Completed	National Cancer Institute (NCI)	Phase 2	This study will examine whether the experimental drug BMS 247550 (Ixabepilone) is an effective treatment for kidney cancer. BMS 247550 belongs to a class of drugs called epothilones that interfere with the ability of cancer cells to divide. In the way they kill cells, they are very similar to a class of compounds known as the taxanes, which include the drug Taxol. Other characteristics of the epothilones, however, enable them to work in cells that are resistant to Taxol. Patients 18 years of age or older with kidney cancer that has not spread to the central nervous system (unless the brain tumor has remained stable for at least six months after surgical or radiation treatment) may be eligible for this study. Pregnant or nursing women may not participate. Candidates are screened with various tests that may include blood and urine tests, electrocardiogram (EKG), and chest x-ray. Computerized tomography (CT) scans or X-rays, and possibly nuclear medicine studies may be done to determine the extent of disease. Participants receive BMS 247550 by a 1-hour infusion into a vein for 5 consecutive days (days 1, 2, 3, 4 and 5) of each 21-day treatment cycle. Patients must stay in the National Institutes of Health (NIH) area near Bethesda, Maryland, for 7 to 8 days during the first treatment cycle and for the 5 days of treatment in subsequent cycles. The total number of cycles will vary among patients, depending on their individual clinical situation. The drug dose may be increased gradually in subsequent cycles in patients who can tolerate such increases. In addition, participants undergo the following tests and procedures: - Periodic physical examinations and frequent blood tests - X-ray and other imaging studies to determine if the tumor is responding to the treatment. - Tumor biopsies to confirm the diagnosis or spread of tumor and to examine the reaction of certain proteins in cancer cells to BMS 247550. Two biopsies will be done. For this procedure, a small piece of tumor tissue is withdrawn through a needle under local anesthetic. Treatment will be stopped in patients whose tumor grows while receiving BMS 247550. Patients whose tumor disappears completely will be followed at NIH periodically for examinations and tests. Patients whose disease does not completely resolve or whose disease recurs may be advised of other appropriate research protocols at NIH or, if none are available, will be returned to the care of their local doctor.
NCT00038402	Evaluation of the Addition of Herceptin to Standard Chemotherapy in the Neoadjuvant Setting for Operable Breast Cancer	Completed	Genentech, Inc.	Phase 3	The purpose of this study is to evaluate the addition of Herceptin to standard chemotherapy treatment of patients newly diagnosed with operable breast cancer. Other objectives: 1) to evaluate the potential of this therapy to reduce the size of the tumor and increase the possibility of breast conservative surgery, 2) evaluate the ability of this regimen to prevent recurrence of breast cancer and impact on survival, 3) determine side effect profile with the addition of Herceptin, and 4) evaluate significance of HER2 expression by two different methods.
