NCT00077636
This study will evaluate the efficacy and safety of different durations of treatment with PEGASYS combined with ribavirin in patients with CHC genotype 2 or 3 infection who have never previously received interferon (IFN) therapy. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ individuals.
NCT00892437
The objective of this study is to evaluate the safety and efficacy of a regimen containing cobicistat-boosted atazanavir (ATV+COBI) plus emtricitabine/tenofovir disoproxil fumarate (Truvada®; FTC/TDF) versus ritonavir-boosted atazanavir (ATV+RTV) plus FTC/TDF in HIV-1 infected, antiretroviral treatment-naive adults. Participants will be randomized in a 2:1 ratio. Randomization will be stratified by HIV-1 RNA level (≤ 100,000 copies/mL or \> 100,000 copies/mL) at screening. After Week 48, participants will continue to take their blinded study drug and attend visits every 12 weeks until treatment assignments are unblinded, at which point all participants will return for an unblinding visit and be given the option to participate in an open-label rollover extension and receive ATV+COBI+FTC/TDF until COBI tablets become commercially available, or until Gilead Sciences elects to terminate the study.
NCT00002546
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy is more effective than combination chemotherapy in treating patients with cancer of the uterus. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to combination chemotherapy in treating patients with cancer of the uterus.
NCT02603068

NCT01352845
This study is looking at a new vaccine that might prevent meningococcal disease, and will study the immune response elicited by this vaccine when given to healthy young adults. The study will also look at the safety of the new vaccine as well as how it is tolerated.
NCT01748786
The purpose of this study is to compare an online 12-module intervention designed to improve emotion regulation and social relations via mindfulness training with a 12-module program that provides information about health behaviors to individuals with fibromyalgia. The mindfulness training program is expected to produce greater day-to-day improvements than the education condition in individuals' efficacy for coping with pain and stress, positive and negative affect, and positive engagement in social relations assessed via online diaries completed each evening during the intervention period.
NCT01300533

NCT01697072

NCT01343667
The objective of this study is to provide an ongoing evaluation of clinical outcomes associated with the GORE Flow Reversal System and the GORE Embolic Filter when used for embolic protection during carotid artery stenting.
NCT00793468
The purpose of this study is to determine the effect of GSK598809 as compared to placebo in preventing recently-quit smokers from going back to smoking.
NCT01728324
The aim of the study is to confirm efficacy and safety of treatment with 600 mg of BID BI 207127 in combination with 120 mg QD FDV and RBV for 16 or 24 weeks in target chronically infected HCV GT1b treatment naïve patients, including patients with compensated cirrhosis.
NCT00023530
The purpose of this network is to accelerate research in hematopoietic stem cell transplantation by comparing novel therapies to existing ones.
NCT01953679
To compare the pharmacodynamic effects of 2 continuous dose regimens of ulipristal acetate 5.0 and 10.0 mg-only oral contraception, versus a 24/4 day regimen of UPA 5.0 mg.
NCT01087944
This randomized, cross-over, open label study will compare the tolerability and handling of application of peginterferon alfa-2a \[Pegasys\] by autoinjector versus pre-filled syringe in patients with chronic hepatitis C, either on treatment with peginterferon alfa-2a for at least 12 weeks or treatment-naïve for peginterferon alfa-2a. Patients will be randomized to self-injection of 180mcg peginterferon alfa-2a once a week using either an autoinjector or a prefilled syringe for 3 weeks, then switch to use the other method of injection for another 3 weeks. Anticipated time on study treatment is 6 weeks. Target sample size is \<100 patients.
NCT00425815
The TURNS is a National Institute of Mental Health (NIMH) funded contract for the evaluation of new compounds for the treatment of cognitive impairments in schizophrenia (HHSN 27820044 1003C; P.I.: Steve Marder, M.D.). Despite advances in the safety, tolerability, and effectiveness of antipsychotic medications for the treatment of schizophrenia, many patients continue to be plagued by impairments in social and work functioning. Persons with schizophrenia commonly show deficits in a number of areas of cognition that include impairments in attention, memory, and executive functioning (the ability and organize one's behavior). Importantly, a large body of literature now shows a link between cognition and community functioning in schizophrenia. It is believed that treatments that improve cognitive deficits may lead to improvements in work and social functioning. A promising approach to improve the community functioning of patients with schizophrenia is to develop new agents that treat the cognitive deficits of the illness. One type of pharmacological compound that has shown promise at improving cognition is a group of drugs called ampakines. These drugs are believed to improve the activity of a neurotransmitter system in the brain called the glutamate system. Increased activity of this system has been linked to improvements in cognitive functioning. The current study is an eight-week trial comparing two doses of the ampakine drug, Org 24448, that will be added to patients' current atypical antipsychotic medication. One hundred thirty-five patients with schizophrenia, drawn from seven sites, will participate in the study. Cognition will be measured using a variety of paper-and-pencil and computerized measures from the consensus-derived NIMH Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) cognitive battery. Psychiatric symptoms and the ability to perform community-based tasks of daily living will also be measured. Because previous trials with this drug and other similar drugs have detected lasting cognitive benefits, this trial will also repeat clinical assessments four weeks after completion of the study medication.
NCT00700713

Objectives: * To assess the persistence of antibody responses three years after one or two doses of Menactra® vaccine in subjects who participated in study MTA26. * To describe the antibody responses to a single dose of Menactra® vaccine in subjects who had previously received one or two doses of Menactra® vaccine and in Menactra® vaccine-naïve subjects. * To describe the safety profile of a single dose of Menactra® vaccine in subjects.
NCT00624468

The study was randomized. Study medication was administered via subcutaneous (under the skin) injections.
NCT02247934
The objectives of this qualitative study are to elicit concepts about symptoms that are important to patients with primary sclerosing cholangitis (PSC), as well as the key impacts of symptoms on patients' day-to-day functioning.
NCT00828737
Patients with moderate to severe renal impairment scheduled for a magnetic resonance imaging (MRI) scan and injection with a contrast agent, Gadovist, will be asked to participate. The administration of contrast agents that contain gadolinium such as Gadovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Gadovist. Patients who are enrolled in this study will receive a Gadovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
