Active clinical trials for "Non-alcoholic Fatty Liver Disease"

The study will evaluate the effect of coadministration of a range of doses of DGAT2i with 1 dose of ACCi, on hepatic steatosis and the ability of DGAT2i to mitigate ACCi-induced elevations in serum triglycerides. The study has a 2-part design with sequential conduct of Part 1 and Part 2 with each part conducted in distinct/separate cohorts of participants. The overall study design, objectives/endpoints, eligibility criteria for both parts is envisioned to be identical, however, data from Part 1 will be used to determine whether to conduct Part 2.

Glucagon is secreted from pancreatic alpha-cells in response to protein-rich meals and during hypoglycemia. A physiological feedback system exists between the liver and the pancreatic alpha cells termed the liver-alpha cell axis and signifies the role between amino acid-stimulated glucagon secretion and glucagon-stimulated amino acid metabolism. Individuals with non-alcoholic fatty liver disease have increased levels of glucagon (hyperglucagonemia) and amino acids (hyperaminoacidemia), which suggests that hepatic steatosis may uncouple glucagon's effect on amino acid metabolism (i.e. reduced glucagon sensitivity). Since hyperglucagonemia contributes to diabetes progression - due to its potentiating effects on hepatic glucose production - hepatic steatosis may create a diabetogenic circle. This study aims to develop and evaluate a test for measuring glucagon sensitivity in humans. The investigators (Associate Prof. Nicolai J Wewer Albrechtsen and Prof. Jørgen Rungby) will investigate whether amino acid metabolism is attenuated in individuals with hepatic steatosis (assessed by magnetic resonance imaging) due to impaired hepatic glucagon sensitivity and if glucagon's effect on hepatic glucose production is intact compared to individuals without hepatic steatosis suggestive of biased signaling.

Excessive fat in the liver is associated with impairments in metabolic health. Reducing the amount of carbohydrates and fat both have been shown to reduce liver fat. However, not only the amount fats and carbohydrates, but also their quality have been shown to influence liver fat. Diets high in saturated fatty acids (SFA) and diets with a high glycemic index (GI) have been shown to increase liver fat content. However, available data from human dietary intervention studies is limited and these studies did not reflect a realistic diet. In the present study a combination of low GI/SFA on the one hand and high GI/SFA on the other hand is used to reflect realistically a healthy and an unhealthy diet as they are actually consumed by the Dutch population. The primary objective of this study is to investigate whether a two-week low compared to high GI/SFA diet reduces liver fat content. In addition, it will be investigated whether a two- week low compared to high GI/SFA diet reduces DNL, lowers the 24-hour glycemic response, lowers hepatic glycogen content, increases hepatic fat oxidation and changes hepatic lipid composition. Furthermore, the metabolic response to a meal (metabolites related to energy metabolism and substrate oxidation) will be studied upon the low and high GI/SFA diets.

The purpose of this study is to examine how acute nutritional challenges affect levels of several proteins involved in metabolism. These proteins will be measured in blood and fat tissue. This study will have several aims. One aim is to examine the effect of 72 hours of fasting on fibroblast growth factor-21 (FGF-21) levels. Participants will spend 3 days and nights in the Clinical Research Center at the Beth Israel Deaconess Medical Center in Boston, MA. Daily blood samples will be taken. Two fat samples will be taken prior to and at the end of the fast. A subset of participants will also have two MRIs, one prior to and one at the end of the fast. We will study healthy adults and obese adults with liver-biopsy-diagnosed non-alcoholic fatty liver disease (NAFLD). THIS STUDY ARM IS CURRENTLY NOT RECRUITING Another aim is to examine the effect of low-calorie diet on FGF-21 levels. Subjects will follow a hypocaloric diet that will be designed to achieve 3-5% weight loss. We will enroll participants with liver-biopsy-diagnosed non-alcoholic fatty liver disease. Participants will report weekly to the Clinical Research Center at Beth Israel Deaconess Medical Center for weight measurements. Blood will be drawn before and after the weight loss. Participants will also have an MRI before and after the weight loss. THIS ARM IS CURRENTLY NOT RECRUITING Another aim of the study is to examine the effect of acute ingestion of glucose, fructose, and other sugars on serum FGF21 levels. Subjects in this study will be lean volunteers and individuals with metabolic syndrome. THIS ARM IS CURRENTLY RECRUITING

This is a double-blind, placebo-controlled study in adults with non-alcoholic steatohepatitis and Type 2 Diabetes Mellitis on stable dose of metformin monotherapy. Participants will be treated for 16 weeks with placebo or 1 of 2 doses of investigational product to determine the effect on liver fat, HbA1c, safety, tolerability and pharmacodynamics.

This study is an open labelled Phase I/II clinical trial, designed to evaluate the safety and efficacy of an oral cholecystokinin (CCK) receptor antagonist, proglumide, at escalating doses in subjects with NASH. An extended use protocol has been approved for subjects completing this study that show benefit or are at risk of Liver disease progression to continue on Proglumide at 1200 mg / day for an additional 3-9 months. Subjects in the extended protocol will have telephone visits monthly and in the research unit every 3 months for safety lab tests and research blood for fibrosis analysis.

A Phase 1, Open-label Study of the absorption, metabolism, and excretion of a single oral dose of [14C]EDP-305 in healthy male subjects.

This study evaluates how 4-week supplementation with hydrogen-rich water affects liver fat accumulation, blood lipid profiles and body composition in patients with non-alcoholic fatty liver disease

The objective of the study is to investigate how exogenously administered glucagon affects hepatic lipid, glucose and protein metabolism as well as appetite, food intake and resting energy expenditure.

The study is planned as a 3 part design with investigator and participant blinded (sponsor-open), placebo controlled, randomized, dose escalation in Part 1 and Part 2; and a randomized, open label design, in Part 3 (if conducted).
