NCT01283971
This randomized, parallel-group study will assess the efficacy and safety of RoActemra/Actemra (tocilizumab) versus adalimumab, both in combination with methotrexate (MTX) in patients with moderate to severe active rheumatoid arthritis. Patients, already treated with MTX at stable doses, will be randomized to receive either RoActemra/Actemra 8 mg/kg intravenously (IV) every 4 weeks or adalimumab 40 mg subcutaneous (SC) every 2 weeks. All patients will receive methotrexate (10-25 mg weekly) and folate (at least 5 mg weekly). The anticipated time on study treatment is 24 weeks.
NCT00520143
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 objective of this expanded access study is to provide patients with Pompe disease in the United States (US), access to alglucosidase alfa produced from a scaled up manufacturing process for a limited time until production at this scale is approved for commercial use by the Food and Drug Administration.

NCT00862459
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
NCT00254852
The purpose of this study is to compare Optecure™ as an autograft extender (treatment) to autograft alone (control) in patients undergoing 1 or 2 level fusion of the lumbar spine(one level is defined as two adjacent vertebrae), L2 and below. The primary endpoint will be the assessment of fusion by evaluation of x-rays taken following surgery at each visit. The x-ray evaluation will be conducted by a radiologist who is blinded to the type of treatment each patient has received. Subjects will be seen at 6 weeks, 3 months, 6 months, 12 months, and 24 months postoperative (post-op). Questionnaires and x-rays will be completed at each visit and a computed tomography (CT) scan will be taken at the 12 month visit(and used to aid in assessment of bridging bone, where appropriate).
NCT00405275
Rheumatoid arthritis (RA) is a chronic inflammatory disease of the joints leading to joint destruction, with significant long-term morbidity and mortality. Early treatment of RA patients with disease-modifying antirheumatic drugs (DMARDs) significantly decreases these complications. Methotrexate (MTX) is an excellent, economical first-line DMARD used to treat a majority of RA patients. While most patients respond well to MTX, many continue to have active disease. Therefore, understanding how to best treat RA patients with active disease despite MTX therapy is critically important. Although a number of therapies with significantly different economic implications have been shown to be effective when added to MTX, no trial has directly compared active therapies. This study will compare therapeutic strategies using two regimens with proven efficacy when added to MTX therapy; a) hydroxychloroquine and sulfasalazine (cost \~ $1000 per year); b) the tumor necrosis factor inhibitor, etanercept (cost \~ $12,000 per year). We propose a bi-national multi-center randomized, double-blind equivalency trial comparing (A) the strategy of initially adding hydroxychloroquine and sulfasalazine to MTX in patients with active disease despite MTX, with a switch at 24 weeks to etanercept in nonresponders to (B) a strategy of adding etanercept to MTX, with a switch to hydroxychloroquine and sulfasalazine in nonresponders at 24 weeks. If we find that the strategy of first adding hydroxychloroquine and sulfasalazine to MTX identifies a subset of responsive patients and that there is no harm to nonresponders because of early rescue with etanercept, then this less expensive option should become the standard treatment for MTX resistant patients. Four hundred and fifty RA patients with active disease despite treatment with MTX as indicated by a Disease Activity Score with 28 joints (DAS28) of \>4.4 units will be randomized. A DAS improvement of \<1.2 (validated as clinically significant) at 24 weeks will be used to identify early nonresponder who will switch therapy. Subjects with a DAS28 improvement of \> 1.2 at 24 weeks will remain on their initial therapy. The primary endpoint is the change of DAS 28 scores from baseline to 48 weeks. The secondary endpoint is comparison of radiographic progression of disease at 48 weeks, as measured by the change in Sharp score. Economic and functional outcomes will be assessed and a serum and DNA bank will be established to evaluate potential biomarkers predictive of treatment response/toxicity and disease progression. This trial will recruit 450 subjects over 40 months. At the end of the 48 week blinded active therapy portion of the trial, the blind will be broken and data will be collected in an open fashion until all 450 patients have completed the 48 week portion of the trial.
NCT00005958
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy with gemcitabine and docetaxel plus filgrastim in treating patients who have locally recurrent or advanced urothelium cancer.
NCT00763932

NCT02058342
Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Measurements of children and parent dyads are assessed at baseline and at the end (week 24) of the intervention or control periods. Outcome measures include PA, body composition, motor proficiency, central sensory reception and integration (subsample of children only), quality of life and physical activity self-efficacy. PA intervention compliance is monitored using mail-in daily self-report checklists.

NCT01586533
This double-blind, randomized, comparator-controlled Phase II study is designed to establish the safety and efficacy of Zoenasa Rectal Gel compared to mesalamine enema in subjects with left-sided ulcerative colitis, as measured by the modified ulcerative colitis disease activity index (UCDAI), over 6 weeks of treatment. In this study, two cohorts of subjects will receive either Zoenasa-1:4 (1.0g NAC; 4.0g 5-ASA) investigational drug enema therapy or comparator mesalamine enema (4.0g 5-ASA). The study will enroll subjects randomized equally into the 2 cohorts. Each cohort will enroll approximately 60 subjects. The two arms of the trial will be enrolled concurrently in a randomized fashion.
NCT00002485
RATIONALE: Taking part in a clinical trial may help children with cancer receive more effective treatment. PURPOSE: Determine why patients who are eligible for protocols made available through the Pediatric Oncology Group do not enroll in them, and develop strategies to increase enrollment on these clinical trials.
NCT00930787
Support of a ventral hernia repair with a prosthetic mesh has been demonstrated to result in a diminished rate of hernia recurrence. The patient with co-morbidities undergoing hernia repair is at increased risk of wound related complications, which may be exacerbated by the choice of prosthetic mesh, and which are known to influence the ultimate rate of hernia recurrence. It is hypothesized that patients receiving a mesh of biologic origin may experience fewer wound related complications and hence at least an equal rate of hernia recurrence, compared to those receiving a synthetic mesh.
