A Study of the Safety of R256918 in Obese Patients
ObesityNutritional and Metabolic Diseases3 moreThis study investigates the safety of 12 weeks of treatment with R256918, in obese patients (JNJ-16269110 and R256918 are different names for the same molecule). The primary objective of the study is to investigate mean changes in Hepatic Triglyceride Content (HTGC), which is the fat content of the liver, from baseline to week 6 and 12 by 1H-Magnetic Resonance Spectroscopy (MRS), a specialized non invasive radiology test. Additional measures include body mass index (BMI), fasting glucose,lipid levels, and blood pressure. Safety assessments performed during the trial include laboratory tests, vital sign measurements, and adverse event reporting.

ObesityNutritional and Metabolic Diseases3 moreThis study investigates the effectiveness and safety of 12 weeks of treatment with JNJ-16269110 (R256918), in overweight and obese patients. The primary measure of effectiveness is the change in body weight at a clinically relevant dosage level during treatment. Additional measures include body mass index (BMI), DEXA (dual X-ray absorptiometry which is a specialized x-ray test that measures body composition), fasting glucose, lipid levels, and blood pressure. Safety assessments performed during the trial include laboratory tests, vital sign measurements, and adverse event reporting.
One Year Glargine Treatment in CFRD Children and Adolescents
Cystic FibrosisGlucose Metabolism DisordersGlargine treatment can improve the clinical features in Cystic Fibrosis patients affected by glucose derangements
Fenofibrate in Dyslipidemia and Metformin-Controlled Diabetes
Dyslipidemia/Glucose Metabolism DisorderThe primary objective was to assess the effect of 3-month treatment of low and standard doses of fenofibrate in combination with stable dose of metformin on fasting triglycerides levels in patients with type 2 diabetes and dyslipidemia.
The Effects of Potassium Citrate on Bone Metabolism
Bone DiseasesMetabolic2 moreSkeletal buffering of chronic acid loads may contribute to a significant amount of bone loss over time. Evidence from a few small short-term studies suggests that basic compounds, namely potassium citrate and potassium bicarbonate may reduce bone loss and improve bone density. The purpose of this study is to evaluate the effects of potassium citrate on bone metabolism. We hypothesize that administration of potassium citrate to postmenopausal women with osteopenia will reduce bone resorption and improve bone mineral density. Postmenopausal women with osteopenia (T score between -1.0 and -2.5) and no history of fracture will be randomized to either daily potassium citrate or placebo for one year. Primary outcomes will be markers of bone turnover, which will be measured over 12 months. Secondary outcomes will be bone mineral density, compliance, and adverse events.
Study of Alendronate to Prevent and Treat Osteoporosis in Cystic Fibrosis Patients
Cystic FibrosisOsteoporosis2 moreThe primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.
NMR-based Metabolic Profiling Identifies High Risk of MAFLD Patients With Advanced Fibrosis
Metabolic Dysfunction-associated Fatty Liver DiseaseMetabolic DiseaseThis study aim to find out metabolic molecules in blood and urine which could identify high risk of advanced fibrosis in MAFLD patients via NMR-based metabolic profiling.

Purine-Pyrimidine MetabolismMetabolic DiseaseBackground: Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that can be fatal. DPPMs are not well understood, and researchers want to learn more about what causes them and how to treat them. Objective: To learn more about factors that affect DPPMs by comparing test results from affected, uaffected family members, and healthy people. Eligibility: Three types of participants are needed: people aged 1 month and older with DPPMs; their family members who do not have DPPMs; and healthy volunteers. Design: Participants with DPPMs will come to the clinic once a year; some may be asked to come more often. At each visit, all affected participants will have a physical exam and give samples of blood, urine, saliva, and stool. Depending on their symptoms, they may also have other procedures, such as: Swabs of their skin and inside the mouth. Tests of their heart, kidney, brain, and nerve function. Questionnaires about what they eat. Dental exams, and exams of their hearing and vision. Tests of their learning ability. Monitoring of their physical activity. Imaging scans. Photographs of their face and body. These tests may be spread over up to 7 days. Affected participants may remain in the study indefinitely if they wish to. Healthy volunteers and family members will have 1 study visit. They will have a physical exam and may be asked to give blood, urine, saliva, and stool samples.
Brown Adipose Tissue as Nutrient Buffer Through Diet Induced Thermogenesis
Brown Adipose TissueMetabolic DiseaseTo test the hypothesis that active BAT improves metabolic health by buffering postprandial metabolites plasma metabolites and energy expenditure will be compared in volunteers with and without active BAT. Both groups will receive test meals with protein, fat and carbohydrates separately, so that the individual impacts of these macronutrients on diet induced thermogenesis and the buffering function of BAT can be derived. BAT biopsies will be taken before and after the test meals for molecular analysis.
Glucose Homeostasis and Apple Polyphenols
PreDiabetesImpaired Glucose Tolerance1 moreThe primary objective is to investigate the effect of apple polyphenol supplementation for 12 weeks on glucose homeostasis in prediabetic individuals. Further, this study has three secondary objectives: 1) to investigate whether daily supplementation at breakfast and dinner with apple polyphenols for 12 weeks affects the rhythm of glucose uptake over the day and reduces fasting glucose levels and postprandial glucose peaks; 2) to determine the effect of daily supplementation with apple polyphenols for 12 weeks on biomarkers of metabolic health; 3) to assess whether daily supplementation with apple polyphenols for 12 weeks alters fecal SCFA concentrations and fecal microbiota composition.
