NCT00345176
Oral supplementation with the Age-Related Eye Disease Study (AREDS) formulation (antioxidant vitamins C and E, beta carotene, and zinc) has been shown to reduce the risk of progression to advanced age-related macular degeneration (AMD). Observational data suggest that increased dietary intake of lutein + zeaxanthin (carotenoids), omega-3 long-chain polyunsaturated fatty acids (docosahexaenoic acid \[DHA\] + eicosapentaenoic acid \[EPA\]), or both might further reduce this risk. AREDS2 was designed to test whether adding lutein + zeaxanthin, DHA + EPA, or lutein + zeaxanthin and DHA + EPA to the AREDS formulation might further reduce the risk of progression to advanced AMD. A secondary goal was to test the effects of eliminating beta carotene and reducing zinc dose in the AREDS formulation.
NCT02226133

NCT01712984
The aim of the study is to demonstrate safety and immunogenicity of the quadrivalent influenza intradermal (QIV-ID) vaccine compared to the trivalent influenza vaccine (TIV) containing the B strain from the primary (Yamagata) lineage (TIV-ID1) and the trivalent influenza vaccine containing B strain from the alternate (Victoria) lineage (TIV-ID2) vaccines in producing protection against four strains of influenza virus. Primary Objective: * To demonstrate that QIV-ID induces an immune response (as assessed by hemagglutination inhibition (HAI) geometric mean titers (GMTs) and seroconversion rates) that is non-inferior to responses induced by TIV-ID1 and TIV-ID2 for the 4 virus strains at 28 days post-vaccination. Secondary Objectives: * To demonstrate that each B strain in QIV-ID induces an immune response (as assessed by HAI GMTs and seroconversion rates) that is superior to the response induced by the TIV-ID that does not contain the corresponding B strain. * To describe the rate of post-vaccination seroprotection induced by QIV-ID and TIV-ID. * To describe post-vaccination immunogenicity stratified by age (18-49 years and 50-64 years), race, ethnicity, gender, previous vaccination status, and baseline seropositivity status. * To describe the safety profile for subjects who receive QIV-ID and TIV-ID. Observational Objectives: * To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 2 or Grade 3 solicited systemic reactions combined * To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 3 solicited injection site reactions combined.
NCT00457977

NCT00806962
Randomized, double blind, multi-site, study in healthy adults, comparing safety and immunogenicity of two dosage levels of Norwalk VLP Vaccine with adjuvant/excipients and with placebo controls Primary Objective: * Safety as determined by occurrence of local intranasal symptoms or other symptoms as reported by a self-administered memory aid for 7 days after each vaccination and hematology, blood chemistry and physical examinations performed by the clinical research staff * Subjects will also be monitored for Serious Adverse Events (SAEs), and onset of any new medical conditions for 180 days following the last study vaccinations (Day 201). Secondary Objectives Evaluations of immunogenicity as determined by: * Geometric mean titers and seroconversion rate of serum anti- Norwalk VLP IgG and IgA * Stimulation of anti-Norwalk VLP IgA antibody secreting cells (ASC) * Presence of antigen specific memory B-cell response Cells will be collected and stored for possible future evaluation of Norwalk VLP-specific cell-mediated immune (CMI) responses Study Hypothesis: The incidence of adverse events after intranasal Norwalk VLP Vaccine will be the same as the incidence of adverse events after intranasal adjuvant/excipients alone. Norwalk VLP Vaccine and adjuvant/excipients will have a higher incidence of mild to moderate nasal adverse events compared to placebo but similar incidence of other adverse events. Two doses of the 100 µg of Norwalk VLP Vaccine will be more immunogenic than two doses of 50 µg of Norwalk VLP Vaccine. The post-vaccination serum antibody responses, the number of antibody secreting cells (ASC) and IgG and IgA memory B-cell responses directed against Norwalk Virus antigen will be increased after Norwalk VLP Vaccine compared to adjuvant/excipients and to placebo.
NCT00521144
This phase I/II trial is studying the side effects and best dose of obatoclax mesylate when given together with topotecan hydrochloride and to see how well they work in treating patients with relapsed or refractory small cell lung cancer or advanced solid tumors. Obatoclax mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving obatoclax mesylate together with topotecan hydrochloride may help kill more tumor cells

NCT00006382
RATIONALE: New imaging procedures such as spiral CT may improve the ability to detect lung cancer in patients who are at high risk for the disease. PURPOSE: Randomized clinical trial to compare the effectiveness of a spiral CT scan with that of a chest x-ray in detecting lung cancer in patients who are at high risk for the disease.
NCT00113035
Pompe disease (also known as glycogen storage disease type II) is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. The primary objective of this study is to identify potential candidates for future clinical studies in Pompe disease.
NCT01160484
This is a phase II, multicenter, open label, nonrandomized study to evaluate the efficacy and safety of lenalidomide at a dose of 10 mg/dose in combination with bortezomib at 1.0 mg/m2/dose, pegylated liposomal doxorubicin (PLD) at 4.0 mg/m2/dose, and intravenous (IV) dexamethasone at 40 mg/dose in adult patients with relapsed/refractory multiple myeloma (MM). The study consists of a screening period, followed by up to eight 28 day open label treatment cycles, a final assessment to occur 28 days after the end of the last treatment cycle, and a follow-up period.

NCT00285246
Background: Previous deployments like that to the Persian Gulf in 1991 produced veterans with post-deployment symptom-based health problems with no medical explanation. This was termed Gulf War illness or medically unexplained illness (MUI). If previous wars are any indication, some soldiers currently deployed to hostile areas also will return home with unexplained symptom-based illnesses. However, when this study began there was virtually no pre-war, prospective data on risk and resilience factors associated with MUI. This study is attempting to fill that gap. Objectives: Our goals are to: (a) determine pre- and immediate post-deployment factors predicting later MUI and poor functional status, (b) improve previous methodological problems (e.g., selection bias, recall bias and lack of baseline controls) in studies of MUI, and (c) relate pre-deployment risk factors (e.g., personality, stressor reactivity) and resilience factors (e.g., coping style, social support) to post-deployment functional status.
NCT01357239
This Phase IIb study is designed to assess whether 3 doses of AFQ056 are safe and effective in treating the behavioral symptoms of Fragile X Syndrome.
NCT00525941
NBI-34060 is an investigational (research) medication being studied in people with insomnia. The current study is designed to evaluate how people, who experience a nighttime awakening with difficulty returning to sleep, feel during the next day after dosing with NBI-34060. The study will also examine the pattern and extent of nighttime awakenings as reported by the patients, as well as and the patient's sleep experience during treatment.
NCT00943995
Hypotheses: 1. The provision of thrice weekly subcutaneous (SQ) recombinant growth hormone (rGH) therapy to children receiving in-center hemodialysis (HD) will result in improved growth. 2. The provision of thrice weekly SQ rGH therapy to children receiving in-center HD will result in improved lean body mass, nutritional status and quality of life. TIW rGH treatment regimen (0.35 mg/kg/week divided into 3 doses, each dose being given at the conclusion of the dialysis treatment) for up to 2 years; growth response, Dual energy X-ray absorptiometry (DEXA), and quality of life (QOL) will be measured. The goal is to enroll 20 children who are Tanner 1 with decreased height SDS and/or decreased height velocity standard deviation scoreS (SDS). If this therapy is demonstrated to be efficacious and improves growth and QOL, this therapy could be easily implemented for all eligible children on HD, since parental acceptance should be better without having to administer the rGH at home and compliance for the child will be assured. The investigators thus propose an important study that has the ability to advance their understanding and provide evidence for the best methods to promote growth in children on dialysis. The results of this study will result in important information that will be of value to the entire pediatric nephrologist community, including health care professionals, patients, and families. In a real sense, this study will build on the 2006 Consensus Conference guidelines for evaluation and treatment of growth failure in children with chronic kidney disease (CKD). This will provide evidence for critical management decisions that can help insure better growth opportunities to more children with CKD.
NCT00124241
This is an extension study for patients who have previously completed Idenix Study NV-02B-003.
