Extension Study of Protocol DFA102 to Examine the Long-Term Safety, Tolerability, and Effect on...
ObesityStudy DFA102E is an extension of Study DFA102, which included a 28-week treatment period with randomized study medication. The purpose of the extension study is to examine the long-term (up to 1 year) safety, tolerability, and effect on body weight of treatment with pramlintide and metreleptin, administered as separate subcutaneous (SC) injections, in obese and overweight subjects.

Effect of Pioglitazone and Exenatide on Body Weight and Beta Cell Function
Type 2 DiabetesHealthy1 morePioglitazone, a drug used in treatment of type 2 diabetes has been shown to improve insulin sensitivity in skeletal muscle, liver, and fat cells. Despite the beneficial effects of pioglitazone to improve insulin sensitivity and reduce cardiovascular disease in high risk type 2 diabetic patients, weight gain has been a limiting factor. Exenatide, another agent used for treatment of T2DM, improves glycemic control and promotes moderate weight loss. In this proposal we will examine the effect of combination therapy with pioglitazone plus exenatide on body weight, fat topography, beta cell function, glycemic control, and plasma lipid levels in subjects with type 2 diabetes mellitus compared to treatment with each drug separately. Assessment of beta cell function will be performed by measuring the maximal insulin secretory capacity using a maximal hyperglycemic stimulus combined with an intravenous arginine stimulus.

Exenatide for the Treatment of Weight Gain Associated With Olanzapine in Obese Adults
Weight GainThe purpose of this research study is to test the safety and efficacy (how well it works) of exenatide as a treatment for weight gain associated with olanzapine in obese adults with Bipolar Disorder, Major Depressive Disorder, Schizophrenia or Schizoaffective Disorder Exenatide has been approved by the FDA for the treatment of Type 2 diabetes. It has not been approved for the treatment of weight gain associated with olanzapine in obese adults with bipolar disorder, Major Depressive Disorder, Schizophrenia or Schizoaffective Disorder

Effects of a Ketogenic Diet on Body Weight and Cardiovascular Risk Factors
ObesityThis pilot study is a randomized, controlled clinical trial to compare anthropometric and metabolic changes associated with six months of weight management by means of a very low carbohydrate diet or a calorically-restricted low fat diet. We hypothesized that the low fat diet would be associated with more weight loss and improvement of cardiovascular risk factors than the low carbohydrate diet.

A Controlled Trial of Protein Enrichment of Meal Replacements for Weight Reduction With Retention...
Weight LossObesityStudy hypothesis: High protein diets have been shown to make people full and and help to retent of muscle mass. This study was designed to determine effects of a protein- enriched meal replacement (MR) on weight loss and muscle mass retention by comparison to an equal calorie carbohydrate-enriched MR. Methods: Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two equal calorie meal plans.,1) 2.2 g protein/kg of LBM per day [high protein diet (HP)] or 2) 1.1 g protein/kg LBM/day standard protein diet (SP). Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks.

Exploratory Study to Investigate the Effect of Dapagliflozin and Exenatide Combined on Body Weight...
ObesityObesity is a medical condition which increases the risk of other diseases, such as type 2 diabetes and cardiovascular disease. Obesity-related risk factors for the development of other metabolic diseases include unstable glucose levels and high blood pressure. Dapagliflozin and exenatide are both approved worldwide for treatment of patients with Type 2 Diabetes. Dapagliflozin works by lowering glucose levels by inhibiting the renal reabsorption of glucose and thereby promoting its urinary excretion and energy loss and thereby reduction in body fat. Exenatide exhibits many of the same glucose-lowering actions of that of a naturally occurring hormone and leads to weight loss mainly via reduced energy intake, most likely via a central effect on appetite regulation. The purpose of this exploratory study is to investigate if a combination treatment with dapagliflozin and exenatide have a synergistic effect on weight loss in non-diabetic obese subjects. Subjects will be treated for 24 weeks with either active combination treatment or placebo (non-active treatment). Neither study personnel nor subjects will know what treatment is given. All subjects completing the 24-week double-blind study and who are willing and eligible will be offered to enter a 28-week open-label extension study. All subjects entering the extension study will receive unblinded active study treatment for an additional 28 weeks. Thus the total treatment period for subjects entering the extension study will be 52 weeks.
