RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. It is not yet known which regimen of radiation therapy is more effective in treating patients who have metastases to the lymph nodes in the neck. PURPOSE: Randomized phase III trial to compare different radiation therapy regimens in treating patients who have metastases to the lymph nodes in the neck from an unknown primary tumor.
NCT01517165
Background: * Opioid-withdrawal symptoms include runny nose, body aches, chills, sweating, and diarrhea. Many people have these symptoms when trying to stop using opioid drugs. Long-acting opioids like methadone and buprenorphine are used to help people stop using other opioids, but these drugs can cause the same withdrawal symptoms. There are no non-opioid drugs that are approved specifically to treat those symptoms. * Pioglitazone is a drug used to treat type 2 diabetes. In a research study, the drug allowed heroin users to decrease their methadone dose faster without much discomfort, and stay abstinent from heroin. Researchers want to learn more about how pioglitazone helps treat opioid withdrawal symptoms. Objectives: \- To test whether pioglitazone can reduce opioid withdrawal symptoms. Eligibility: \- Individuals between 18 and 65 years of age who will be using buprenorphine to treat opioid dependency. Design: * This study will last up to 17 weeks. Participants must come to the study clinic every day for at least 13 weeks. * Participants will be screened with a physical exam and medical history. They will also answer questions about drug use habits, and provide blood and urine samples. * Participants will take buprenorphine daily for 7 weeks. For the first 3 weeks, the dose will be increased to a level that should help stop the use of opioids. For the next 4 weeks, the dose will be decreased. Blood, urine, and breath samples will be collected at different study visits. Participants will also fill out questionnaires about mood, drug craving, and withdrawal symptoms. * After 1 week on buprenorphine, participants will start the study pill (pioglitazone or a placebo) every day. They will take the study pill for 13 weeks. * During the treatment period, participants will have drug counseling once a week for 30 minutes. * Some participants have other tests as part of this study. These tests include functional magnetic resonance imaging scans to look for changes in brain activity and giving samples of cerebrospinal fluid to study brain chemistry. * Participants will have a final followup phone call 3 weeks after the last clinic visit.
NCT01405508
This is a multicenter, open-label, 4-arm, randomized, parallel-group study to evaluate safety and tolerability of Brivaracetam Intravenous (BRV iv) as adjunctive treatment for adults with epilepsy according to an initiation or a conversion scheme, during repeated dosing (100 mg/administration twice daily for 4.5 days).
NCT01835132
Background: \- Scleritis is the inflammation of the white outer coating of the eye, known as the sclera. In severe cases, it can cause blindness. It is commonly associated with autoimmune disorders such as rheumatoid arthritis. Mild scleritis can be treated with drugs such as ibuprofen. More severe scleritis may need oral steroids or immunosuppressive treatments; however, these treatments can cause side effects in the whole body. Gevokizumab is a newer anti-inflammatory drug that is under investigation to treat other inflammatory diseases. It may not have as severe side effects as some other drugs. However, it has not yet been used to treat scleritis. Researchers want to see if it can be given as a safe and effective treatment for scleritis. Objectives: \- To see if gevokizumab is a safe and effective treatment for scleritis. Eligibility: \- Individuals at least 18 years of age who have active scleritis. Design: * There is an initial phase and a two-part extension phase in this study. The extension phase is optional. The initial phase of the study requires seven visits to the National Eye Institute (NEI). * Participants will be screened with a physical exam and eye exam, and medical history will be obtained. Blood and urine samples will be collected. * Eligible participants will receive an injection of 60 mg of gevokizumab at the first study visit and at Weeks 4, 8, and 12. They will be given under the skin by the stomach, or in the upper arm or thigh. * Participants will have additional visits after the first study visit at Weeks 2, 16, and 28. No injection will be given at these visits. Eye exams will be done, and blood and tear samples will be collected. * If the scleritis improves by Week 16, participants may choose to continue the study in the extension phase. In the 1st extension, they will have a visit every 4 weeks until Week 36 and then two additional monitoring visits at Weeks 40 and 52 for a total of 13 study visits. * Participants who are eligible at Week 52 may continue in the "as needed" (PRN) extension phase (2nd extension) and receive gevokizumab injections (60 mg) at Weeks 52, 54, 58 and 62.
NCT01445132
Background: * After allogeneic (donor) stem cell transplantation, a new immune system grows in the patient from the transplanted donor stem cells and lymphocytes (type of immune cell). Donor lymphocytes, unlike the patient s own lymphocytes, often can recognize the patient s tumor cells as being foreign and destroy them. * It is thought that tumor shrinkage after stem cell transplantation is the result of donor T lymphocytes, or T cells. Some studies show that patients with tumors that have T cells are better able to keep tumor growth in check. * Patients who have had donor stem cell transplantation may have donor T cells in their tumors that can recognize and fight their cancer. Compared with donor T cells taken directly from the donor and infused into the patient, donor T cells found in patients tumors may be specific for the cancer cells and thus better able to attack tumor. Also, because the T cells found their way to the tumor, they may be less likely to recognize and attack non-tumor tissues than the T cells given in donor lymphocyte infusions. * The T cells may be especially effective at controlling tumor if they are given an additional stimulus to become active. Costimulation is the name of the body s natural process for providing an extra stimulus, and can be performed on cells in the laboratory. Costimulation can produce large numbers of activated cells that may be able to attack cancer cells and shrink tumors. Objectives: -To evaluate the ability of lymphocytes found in tumors from patients who have received donor stem cell transplants to control their tumor growth. Eligibility: -Patients between 18 and 75 years of age with a B-cell cancer that has continued to grow or recurred after remission following allogeneic stem cell transplantation. This includes patients who have received transplants from unrelated donors and cord blood. Design: * Immune cells are collected from patients blood and blood from their stem cell donor. * Patients undergo surgery to remove their tumor and a small piece of skin. In the laboratory, donor T cells are isolated from the tumor and costimulated to expand the number of cells and activate them. * The expanded, activated T cells as infused into the patient. * Patients have a needle biopsy and possibly surgery to remove a sample of remaining tumor for research studies. * Patients are followed at the NIH clinic 48 hours after the cell infusion, and again at 1, 2, 4, 8 and 12 weeks after the infusion. Tumor size is monitored every month with CT scans, and possibly also with a PET or bone marrow aspiration and biopsy, for the first 3 months after the cells are infused. Thereafter, visits are less frequent (every 3 months, then every 6 months, and then yearly) during a minimum 5-year follow-up.
NCT00559416
Some HIV-infected individuals have a white blood cell marker known as HLA-B\*57 that appears to help control the progress of the disease; however, not all who have the HLA-B\*57 marker are able to control the infection. This study will examine the effects of giving white blood cells with HLA-B\*57 from an individual who controls HIV infection to an individual who cannot control HIV infection, as a form of HIV treatment. All candidates will be screened with a medical history, physical examination, and blood and urine tests. Both donor and recipient volunteers must be HIV-positive individuals 18 years of age or older who have the HLA-B\*57 marker and are receiving care. Donor candidates must have positive HIV antibody tests for at least seven years with a recent CD4 cell count greater than 400 cells/mm?, HIV viral load less than 50 copies/mL, and no previous HIV viral load greater than 1,000 copies/mL. Recipient candidates must have positive HIV antibody tests with a recent CD4 cell count less than 400 cells/mm? and HIV viral load greater than 10,000 copies/mL, and must have failed at least two prior combination antiretroviral regimes and are willing to receive or resume combination antiretroviral therapy. Donor volunteers will be excluded if they have taken certain antiretrovirals drugs, have a medical history of cancer or of other blood-borne illnesses, or have other medical conditions that might interfere with the study. Recipient volunteers will be excluded if they have a medical history of malignant cancer or other medical conditions that might possibly interfere with the study. Donors will undergo apheresis to separate white blood cells from circulating blood before the red blood cells and plasma are returned to the bloodstream. The procedure will take up to five hours, and donors will be required to return for additional tests. Donors may be asked to return for further white blood cell donations, a maximum of six procedures per year. Recipients will undergo apheresis to obtain stem cells for possible use in the study, and will be admitted to an NIH Clinical Center inpatient unit to receive an infusion of white blood cells and undergo a series of blood tests both before and after the infusion. The infusion process will take two hours. After being discharged, recipients will be asked to return to the Clinical Center for monitoring and follow-up tests, and may receive further infusions.
NCT01296139
Background: \- Ferumoxytol is an approved iron replacement therapy agent that has some potential for use as a contrast agent in imaging studies of the lymph system, especially involving lymph nodes that have been affected by cancer. Ferumoxytol is taken up by normal lymph nodes, but excluded from cancerous lymph node tissue. Because Ferumoxytol has not yet been approved for use as an imaging agent, researchers are interested in testing its effectiveness as a contrast agent for studies of normal lymph tissue and cancer tissue in lymph nodes of individuals with prostate cancer. Objectives: \- To evaluate the safety and effectiveness of Ferumoxytol as a contrast agent in individuals who are scheduled to have prostate removal surgery to treat prostate cancer. Eligibility: \- Men at least 18 years of age who have been diagnosed with prostate cancer and are scheduled to have surgery to remove the prostate and surrounding lymph nodes. Design: * Participants will be screened with a full medical history and physical examination, blood and urine tests, and tumor imaging studies. * Participants will have a magnetic resonance imaging (MRI) scan to provide baseline images for the study. * Participants will receive an injection of Ferumoxytol and will return for another MRI scan on the following day (around 24 hours later). * Some participants may have a third MRI scan 48 hours after the initial injection of Ferumoxytol. This third MRI scan is optional and not required by the study. * Although the scanning and followup portion of the study will last only a few days, participants will be considered to be enrolled on the study until after the prostate removal surgery.
NCT01063335
Background: \- The CB1 receptor is a protein in the brain that is targeted by the active ingredients in cannabis (marijuana). Brain systems that react to cannabis may be involved in the causes and symptoms of schizophrenia and schizoaffective disorder. For instance, research studies have shown that the number of CB1 receptors may be different in people with schizophrenia, and there may be differences in the receptors themselves. Researchers are interested in using positron emission tomography (PET) to study CB1 receptors in people with and without schizophrenia, using a chemical tracer that attaches specifically to CB1 receptors. Objectives: \- To determine whether the CB1 receptor brain protein is different in people with and without schizophrenia. Eligibility: \- Individuals between 18 and 55 years of age who either have been diagnosed with schizophrenia/schizoaffective disorder or are healthy volunteers. Design: * Participants in the study must have previously enrolled in the National Institute of Mental Health protocol A Neurobiological Investigation of Patients with Schizophrenia Spectrum Disorders and Their Siblings (95-M-0150). * Participants will provide blood samples to test for the gene that contains information on the specific type of CB1 receptor each participant has. * Participants will have a PET scan and/or a magnetic resonance imaging (MRI) scan. * The PET scan will last approximately 2 hours. Participants will receive an injection of a small amount of chemical tracer to improve the quality of the images taken during the scan. * The MRI scan will last approximately 1 hour.

NCT01192828
Cystathionine beta-synthase deficiency is an inherited disease that results in elevation of a substance called homocysteine (Hcy) in blood and urine. Individuals with this disorder have a very high risk for developing blood clots and are at risk for developing eye and bone abnormalities. Current treatments are generally difficult to follow and can fail. Development of additional therapies has been limited by lack of understanding of how the disease works. The purpose of this study is to see if oxidative stress and inflammation are involved in the disease process and if short-term supplementation with taurine is an effective treatment. Funding source: FDA.
NCT00940095
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
NCT00855335
The purpose of this study is to study how changes in the body during pregnancy influence the blood levels of TMC114 (darunavir) and ritonavir taken together, darunavir and cobicistat taken as a fixed-dose combination, TMC125 (etravirine) taken alone or with darunavir and ritonavir or rilpivirine in patients with human immunodeficiency virus-1 (HIV-1). This study will examine how these drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time. Any pregnant woman who is currently receiving darunavir with ritonavir, darunavir with cobicistat, etravirine or rilpivirine for HIV-1, and who meets the eligibility criteria for the study, will be allowed to enroll. Patients must be willing to remain on study medication during the course of their pregnancy, and 12 weeks postpartum. The information collected may help answer questions about how to best prescribe these three drugs for pregnant women.
