NCT00734591
In studies of Exubera in persons with diabetes, lung cancer occurred in a few more people who were taking Exubera than in people who were taking other diabetes medicines. All subjects diagnosed with lung cancer had a history of smoking and the number of lung cancer cases observed fell within the expected range based on population-based data. There is currently not enough information to determine if any of the observed lung cancer cases were related to Exubera use, therefore, the study is being conducted to further investigate whether Exubera use makes the appearance of lung cancer more likely.
NCT00376506
This study will compare an implant with the technique of sensory training to determine which method may improve the ability to swallow and reduce the risk of choking. Many people with a brain injury or neurological disorders experience difficulty in swallowing. Past studies have shown that an electrical pulse applied to muscles or an increase in sensory stimulation to the throat can help. Patients ages 18 to 90 who have had a brain injury or neurological disorder and who have had trouble swallowing for 6 months or longer may be eligible for this study. Patients will undergo a physical examination, pregnancy test, and exam by a throat and speech physician. Fiber-optic endoscopic evaluation of swallowing with sensory testing involves a flexible tube passed through the nose to the back of the throat to allow observation of the voice box. Videofluoroscopy, an X-ray of the head and neck, will be done while patients swallow. Patients experiencing trouble with the upper esophagus may undergo additional procedures, including manometry to measure pressure changes in the back of the throat, and reevaluation through the fiber-optic tube. Patients in this study will have a magnetic resonance imaging (MRI) scan, which uses a strong magnetic field to obtain images of the body. Patients will lie on a table that slides into the enclosed tunnel of the scanner. The scan will take 20 to 25 minutes. Patients will be assigned randomly to one of two groups: the intramuscular group, to have a stimulation device implanted in the neck, and the vibrotactile group, to receive a vibrotactile stimulator. All patients will have 10 training sessions with their devices, plus follow-up. Those patients in the first group will undergo surgery, under general anesthesia, for the implant. Three weeks following the implant procedure, patients will come to NIH to have the stimulator turned on and programmed and to learn how to use the device. Those patients in the second group will have about 2 to 3 weeks of training in using a vibrotactile device, and then they will take it home to use. All patients will return to NIH at 3 months to ensure proper use of the devices, and they will visit for follow-up at 6 months and 12 months for tests and questionnaires. ...
NCT00924001
Background: * This study will use cells called DMF5 to treat patients with metastatic melanoma (melanoma that has spread beyond the primary tumor site). * The DMF5 cells were first obtained from a tumor of a patient with melanoma with HLA-A201 tissue type. The tumor cells were grown in the laboratory, and when the laboratory-grown cells were given back to the patient, the patient's tumors shrank dramatically. In laboratory tests, DMF5 cells were also shown to shrink mouse melanoma tumors. Objectives: -To determine whether preparatory chemotherapy followed by infusion of DMF5 cells is a safe and effective for shrinking melanoma tumors. Eligibility: -Patients with metastatic melanoma and tissue type HLA-A201 who are 18 years of age or older. Design: * Patients have a preparatory regimen of chemotherapy with cyclophosphamide and fludarabine followed by infusion of DMF5 cells and then high-dose interleukin. The chemotherapy, interleukin and cells are given intravenously (through a vein). * Patients have frequent blood tests to look for the side effects and response to treatment. * Patients may be asked to have a tumor biopsy (surgical removal of a small piece of tumor tissue) to examine the effects of treatment on the immune cells in the tumor. * Patients have a physical examination, computed tomography (CT) of the chest, abdomen and pelvis and laboratory tests 4 to 6 weeks after treatment and then monthly to evaluate the tumor. * The first group of patients participates in the Phase I portion of the study, called the dose escalation phase. This phase will determine the highest safe dose of DMF5 cells. There will be three dose levels of DMF5 cells, with the first patients enrolled getting the smallest dose and then increasing the dose when the preceding level has been shown to be safe. * Patients in the Phase II portion of the study receive DMF5 cells at the highest dose found to be safe in Phase I, to test the effectiveness of the treatment.
NCT00477321
This study will evaluate the safety of a new experimental drug, IL-7, in people with HIV infection. Animal studies have shown that IL-7 can improve the function and number of infection-fighting cells called T lymphocytes, or T cells. If this study shows that IL-7 is safe, additional studies will be done to see if it can improve the function or numbers of T-cells in HIV-infected persons. HIV-infected persons who have been receiving HAART therapy for at least 12 months before enrolling in the study and have been stable on this treatment for at least 3 months before enrollment may be eligible for this study. Participants have about 10 clinic visits over 3 months. They receive three injections of IL-7, one injection a week for 3 consecutive weeks. The injections are given as a shot under the skin in the arm or leg. On the day of each injection, the participant stays in the clinic for up to 8 hours or longer for observation and collection of blood samples. Three additional visits (one every 3 months) may be scheduled. During the study visits the following may be done: * Medical history, physical examination, blood tests every visit. * Electrocardiogram (EKG) at study days 0 (day of first dose), 1, 7 (day of second dose), 14 (day of third dose) and 21. * Chest x-ray study on day 21. * Blood sample collections at frequent intervals during the first 96 hours after the first dose administration. A catheter (thin plastic tube) may be put into a vein in the arm and left in place to allow several blood samples to be drawn without repeated needle sticks. * Urine tests several times during the study.
NCT00000883
The purpose of this study is to see if there are any changes in sugar and fat levels in the blood when patients take anti-HIV therapy for many years. Another goal is to test memory and mental concentrations to determine if anti-HIV drugs protect the brain from damage caused by HIV. (The purpose of this study has been changed from the original version.) HIV-infected patients with low CD4 cell counts are at risk for getting opportunistic (AIDS-related) infections. CD4 cells are cells of the immune system that help fight infection. Anti-HIV therapy may increase CD4 counts, which may lead to a decrease in AIDS-related infections. Problems that anti-HIV therapy is associated with include metabolic problems, neurologic problems, abnormal opportunistic infections, and cancer. Patients in ACTG 362 have been exposed to anti-HIV therapy longer than any other large group in the ACTG. These patients appear to benefit from their therapy, but also suffer problems from it. Observation of these patients should provide more information about long-term anti-HIV treatment and may detect unexpected problems. (This study as been changed. More information about the reasons for conducting this study has been added.)
NCT01107912
The 5-milligram (mg) maintenance dose (MD) of prasugrel in very elderly patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg MD in non-elderly patients.
NCT00756821
The goal of this pilot study is to identify a marker or panel of markers in the blood or urine from a wide range of Spinal Muscular Atrophy (SMA) patients that segregates with measures of clinical severity. From this identification of candidate biomarkers, it is hoped that further investigations, both longitudinal natural history and clinical efficacy studies, will verify a biomarker with the sensitivity and specificity that will allow its eventual use as a validated pharmacodynamic marker or surrogate endpoint. In addition, this effort may elucidate biological pathways that may be potential therapeutic targets.
NCT00001000
To evaluate the degree and sequence of immunologic enhancement and the cellular resistance to certain infections after a single dose of atvogen (ampligen). In addition, the relationship between activation of immune cells and biochemical markers of that activation will be studied. Treatment of patients with HIV infection must address both the primary viral infection and the subsequent immune deficiency, which is the primary cause of mortality in AIDS. In vitro studies of ampligen have shown it will inhibit HIV infection. Ampligen may also minimize the toxicity of many drugs used in the treatment of AIDS and induce an antiviral state in the brain that may be useful in treating neurologic symptoms of HIV infection. The time course and degree of immunologic response to ampligen remain unknown although they are essential for proper use of the drug in the treatment of HIV infection and perhaps other clinical problems.

NCT00387010
The primary purpose of the study is to evaluate the impact of treatment with fentanyl buccal tablets on the anxiety symptoms commonly associated with chronic pain in patients with breakthrough pain (BTP). Other purposes are to assess the management of BTP, to evaluate patient functioning, and to determine any influences on the successful dose achieved.
NCT00422981
The purpose of this study is to find out if different doses of Investigational Drug are safe, tolerable, and if they have an effect on Mild Cognitive Impairment (MCI).
NCT00084825
RATIONALE: Drugs used in chemotherapy such as docetaxel work in different ways to stop tumor cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Giving docetaxel with imatinib mesylate may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving docetaxel with imatinib mesylate works in treating patients with androgen-independent prostate cancer and bone metastases that progressed while receiving docetaxel and a placebo on clinical trial MDA-ID-030008.
NCT00205855
There are many treatment options available for the management of chronic pain . Some include, but are not limited to, over-the-counter medications, Non-Steroidal Anti-Inflammatory Drugs, Physical Therapy, Transcutaneous Electrical Nerve Stimulation (TENS) and nerve blocks. Historically, the mainstay of pain treatment has been pharmacotherapy. However, pharmacotherapy has varying degrees of effectiveness and is often associated with undesirable side effects. Although many patients are successfully treated, for those who fail some of these more conservative therapies the remaining option is limited to spinal cord stimulation (SCS), proven to be an effective therapy to more than half of those failing conservative treatments . Over 50% of those who have failed these more conservative methods of pain management, can now, under the guidance of a clinician utilizing SCS, have their pain levels successfully managed. SCS is a less invasive therapy that is a reversible treatment with greater long-term benefits than more permanent, radical approaches and one that deserves greater consideration in the management of chronic, intractable pain.
