Multi-center double-masked, placebo-controlled randomized clinical trial designed to evaluate the long-term efficacy of finasteride, or doxazosin, or the combination of both, in delaying or preventing the clinical progression of symptomatic benign prostatic hyperplasia (BPH). MTOPS was the largest and longest study to test whether drug therapy can prevent or delay the noncancerous growth of the prostate. A unique feature of MTOPS that has not been done in prior studies of pharmacotherapy of BPH is the biopsy substudy. A total of 1,082 volunteers from the 2,931 participants randomized during the full-scale phase are currently participating in this substudy. Biopsies of the prostate will be obtained on these volunteers at predetermined times during the course of the trial to evaluate the status of the prostate at key event times. The purpose of the substudy was to provide additional information regarding the histopathobiology of BPH and to test existing biomarkers for their prognostic ability regarding response to drug therapy.

Study designed to test the hypothesis that African-Americans respond less well to combination pegylated interferon and ribavirin therapy than Caucasian-Americans who have chronic hepatitis C genotype 1 and who were not previously treated with either interferon or ribavirin. Reasons for differences in response, regardless of race, will be studied. All patients were treated with combination therapy of pegylated interferon and ribavirin for 48 weeks, and were followed for an additional 48 week safter cessation of therapy. 400 patients, half African-American and half Caucasian American, from 8 clinical centers with the goals of establishing rates of response to optimal current therapy in the two ethnic groups, identify factors predictive of response, establish patterns of viral kinetics in response to antiviral therapy, and test hypotheses concerning viral and host factors determining response to therapy. Four ancillary studies designed to elucidate biological and virological basis for non-response are also included in Virahep-C. Additionally, the study has central facilitates for pathology, the virological testing laboratory and a serum/tissue repository.

International, randomized, double-blinded trial to determine whether weaning to a casein hydrolysate formula during the first 6-8 months of life in place of cow milk based formula reduces the incidence of autoimmunity and type 1 diabetes in genetically susceptible newborn infants. 2160 eligible infants were randomized to test or control formulas when mothers decide to wean from exclusive breastfeeding. The participants will be monitored up to the age of 10 years for the appearance of diabetes-predictive autoantibodies and clinical type 1 diabetes. The TRIGR trial will determine whether delayed exposure to intact food proteins will reduce the chances of developing type 1 diabetes later in life. All babies in the study received the recommendation to breastfeed for at least the first six months of life. If a mother was unable to exclusively breastfeed before the baby was 8 months of age, her child was randomly assigned to one of two groups. One group of these babies received a trial formula based on extensively hydrolyzed protein; the other group received another trial formula containing a smaller amount of hydrolyzed protein. In the hydrolyzed formula, the big protein molecules have been split into very small fragments to provide a source of nutritional amino acids, but the fragments are likely too small to stimulate the immune system. The TRIGR trial will also be able to analyze whether exclusive breastfeeding per se can reduce the risk of the children to develop type 1 diabetes.
Study that compared the outcomes of two minimally invasive surgical procedures to treat stress urinary incontinence in women. These procedures are called mid-urethral slings. The procedures insert a mesh sling or hammock to support the bladder neck so that urine does not leak. Both procedures have been approved by the FDA and have been shown to be safe and successful in treating stress urinary incontinence. However, it is not known if one is better than the other. This study answers that question. The secondary aims of the trial are to compare other outcomes for the two surgical procedures, including quality of life, sexual function, satisfaction with treatment outcomes, complications, and the need for other treatments(s) after surgery. Follow-up will be a minimum of two years. Stress urinary incontinence is the accidental leakage of urine during activities such as coughing, laughing, sneezing, or lifting heavy objects.

Randomized, double blind, nationwide clinical trial to compare the efficacy and safety of three interventions to treat adolescents and youth with type 2 diabetes (T2D): (1) metformin alone, (2) metformin plus rosiglitazone, and (3) metformin plus an intensive lifestyle intervention called the TODAY Lifestyle Program (TLP). The secondary aims are to: compare and evaluate the safety of the three treatment arms; compare the effects of the three treatments on the pathophysiology of type 2 diabetes (T2D) with regards to beta cell function and insulin resistance, body composition, nutrition, physical activity and aerobic fitness, cardiovascular risk factors, microvascular complications, quality of life, and psychological outcomes; evaluate the influence of individual and family behaviors on treatment response; and compare the relative cost effectiveness of the three treatment arms. The study recruits patients over a three-year period and follows patients for a minimum of two years. Patients are randomized within two years of the diagnosis of T2D. Materials that were used for the study are made publicly available: * The TODAY Standard Diabetes Education (TSDE) program, developed especially for youth with type 2 diabetes. (All participants received the TSDE program) * The TODAY Lifestyle Program (TLP) that was among the treatments tested.
Nationwide, randomized, double blind, multi-center research study to determine whether the drug salsalate, a member of the commonly used Non-Steroidal Anti-Inflammatory Drug (NSAID) class, is effective in lowering sugars in patients with type 2 diabetes. The study is conducted in two stages. The primary objective of the first stage is to select a dose of salsalate that is both well-tolerated and demonstrates a trend toward improvement in glycemic control. The primary objective of Stage 2 of the study is to evaluate the effects of salsalate on blood sugar control in diabetes; the tolerability of salsalate use in patients with type 2 diabetes (T2D); and the effects of salsalate on measures of inflammation, the metabolic syndrome, and cardiac risk.

There are more than 20,000 study participants representing all different racial and ethnic backgrounds who have helped SEARCH determine the extent of diabetes in the community and its impact on different populations. The SEARCH Study invites Investigators interested in childhood Diabetes Research to collaborate on matters of interest to the field of childhood Diabetes.
Multicenter, randomized, double-blind, placebo-controlled trial is designed to determine whether daily antimicrobial prophylaxis is superior to placebo in preventing recurrence of urinary tract infection (UTI) in children with vesicoureteral reflux (VUR). The basic eligibility criteria are: (1) age at randomization of at least 2 months, but less than 6 years, (2) a diagnosed first febrile or symptomatic UTI within 42 days prior to randomization that was appropriately treated, and (3) presence of Grade I-IV VUR based on voiding cystourethrogram (VCUG). Patients will be randomly assigned to treatment for 2 years with daily antimicrobial prophylaxis (trimethoprim-sulfamethoxazole) or placebo. The study is designed to recruit 600 children (approximately 300 in each treatment group) over an 18-24 month period. The primary endpoint is recurrence of UTI. In addition, patients will be evaluated for secondary endpoints related to renal scarring and antimicrobial resistance. Scarring will be determined based on renal scintigraphy by 99mTc dimercaptosuccinic (DMSA) scan. Quality of life, compliance, safety parameters, utilization of health resources, and change in VUR will be assessed periodically throughout the study.
The Center develops conceptual models, computational infrastructure, an integrated knowledge repository, and query and analysis tools that enable scientists to effectively access and integrate the wealth of biological data. The National Center for Integrative Biomedical Informatics (NCIBI) was founded in October 2005 and is one of seven National Centers for Biomedical Computing (NCBC) in the NIH Roadmap. NCIBI is based at the University of Michigan as a part of the Center for Computational Medicine and Biology (CCMB). NCIBI is composed of biomedical researchers, computational biologists, computer scientists, developers and human-computer interaction specialists organized into seven major core functions. They work in interdisciplinary teams to collectively develop tools that are not only computationally powerful but also biologically relevant and meaningful. The four initial Driving Biological Projects (prostate cancer progression, Type 1 and type 2 diabetes and bipolar disorder) provide the nucleation point from which tool development is informed, launched, and tested. In addition to testing tools for function, a separate team is dedicated to testing usability and user interaction that is a unique feature of this Center. Once tools are developed and validated the goal of the Center is to share and disseminate data and software throughout the research community both internally and externally. This is achieved through various mechanisms such as training videos, tutorials, and demonstrations and presentations at national and international scientific conferences. NCIBI is supported by NIH Grant # U54-DA021519.
