Filter by:The purpose of this study is to compare ways of giving advice and providing support to improve diet and physical activity in adult primary care patients with elevated body mass index and dysglycemia.
Background: - Metabolic syndrome is a name given to a group of factors that tend to occur together. These risk factors include central obesity (extra weight around the middle of the body) and high blood pressure and blood sugar levels. They also include low levels of HDL ("good cholesterol") and high triglyceride levels. A person is said to have metabolic syndrome if they have three or more of the above risk factors. People with metabolic syndrome are at increased risk for type 2 diabetes, stroke, and heart disease. - Cortisol, a hormone produced by the adrenal glands, is an important regulator of metabolism. People with central obesity and metabolic syndrome may have higher than normal cortisol levels that the body cannot regulate properly. Abnormal cortisol levels may play an important role in metabolic syndrome. Mifepristone is a drug that blocks cortisol. Researchers are interested in studying its effects on metabolic syndrome. Objectives: - To study the effects of short-term mifepristone treatment for metabolic syndrome. Eligibility: - Men and Women between 35 and 70 years of age are overweight or obese, and have abnormal glucose and triglyceride levels. Design: - Participants will be screened with a physical exam and medical history. They will also have blood and urine tests. - Participants will be admitted to the metabolic unit at the National Institutes of Health Clinical Center for the first 3 days of the study: - Day 1: Body measurements (height, weight, waist, hip, and neck) and blood pressure tests. Also, 24 hours of regular blood draws and 24-hour urine collection to monitor regular daily cortisol levels. - Day 2: Glucose/insulin infusion test to measure blood sugar levels. - Day 3: Infusion of cortisol-like compounds and then regular blood draws for about 3 hours to evaluate how cortisol is metabolized. - At the end of Day 3, participants will receive mifepristone or a look-alike capsule to take for 7 days at home. - After 7 days, participants will return to the metabolic unit to repeat the Day 1 and Day 2 study procedures. They will continue to take mifepristone. - One week after the second set of study tests, participants will return for a brief physical exam and blood tests. - The study procedures will be repeated after 6 to 8 weeks, with the other study drug.
PREDICT Validation is a validation pharmacogenetic trial. The purpose of this study is to confirm that some genes can be used to predict how well a subject diagnosed with idiopathic growth hormone deficiency (IGHD) or turner syndrome (TS) will respond to a treatment with recombinant human growth hormone (r-hGH).
The purpose of this study is to investigate long-term treatment with Zomacton® for pituitary short stature in children with insufficient growth hormone production and/or short stature caused by Turner syndrome.
The purpose of this research study is to determine the safety and tolerability of up to five doses of VRS-317 in Adult Growth Hormone Deficient patients. - Patients will be evaluated for evidence of activity of VRS-317 by measurement of changes from baseline in insulin-like growth factor-1 (IGF-I) and binding protein (IGFBP-3), and bone turnover (bone alkaline phosphatase) - Descriptive pharmacokinetic (PK) and pharmacodynamic (PD) parameters (IGF-I and IGFBP-3) will be determined by standard model independent methods based on the plasma concentration-time data of each subject. These parameters include: Cmax, Tmax, AUCavg, AUC0-inf, and t1/2. - The purpose is to determine the appropriate dose of VRS-317 to maintain a normal range (for appropriate age/gender) for IGF-I levels in adult patients for up to one month after administration of a single dose
The purpose of the multicenter, randomized, open-label, controlled phase II study is to determine whether pegylated recombinant human growth hormone is effective in the treatment of children with growth hormone deficiency.
This is a dose escalation study to determine the maximum tolerable dose of Parathyroid Hormone-related Protein, PTHrP, or Parathyroid Hormone, PTH, that can be given safely over one week in healthy African-American volunteers. The investigators plan to infuse low doses of intravenous PTHrP or PTH to determine if it leads to a sustained and progressive suppression of bone formation as occurs in humoral hypercalcemia of malignancy (HHM) or an increase in bone formation as occurs in hyperparathyroidism (HPT). Additionally, the investigators will assess the direct influence of PTHrP and PTH on vitamin D metabolism, markers of bone turnover, and fractional excretion of calcium. These results will be compared to previous studies of Caucasian volunteers.
The goal of this clinical research study is to test an investigational type of packaging for diabetes drugs called "unit-dose packaging." Researchers want to learn if unit-dose packaging can help patients with Type II diabetes to take their drugs on the proper schedule.
Type 2 Diabetes Mellitus (T2DM) is a serious health problem that has increased dramatically worldwide due to the high and increasing prevalence of obesity. Medical management of T2DM is of limited success. Because not well controlled T2DM patients are in high risk of blindness, cardiovascular accident and end staged disease, T2DM has become a major health burden for society. Recent data on the relative effectiveness of gastrointestinal metabolic surgery played as bariatric surgery in the remission of T2DM, suggests that it may be significantly more effective than current medical treatment. In considering that less than half of the T2DM patients can achieve satisfactory treatment goal under current medical treatment, gastrointestinal metabolic surgery shall play an important role in T2DM treatment in the future. However, the indication for metabolic surgery and clinical predictors of success are not clear now. These clinical predictors can help us to choose appropriate not-well controlled T2DM patients to receive metabolic surgery and reduce dverse health outcomes in those patients.
The primary objective of this study is to evaluate the safety and tolerability of PF-04856883 (CVX-096) in adult female subjects with Type 2 diabetes mellitus on high dose of metformin.
