Active clinical trials for "Lipodystrophy"

A previous study substituting zidovudine or stavudine to abacavir in patients with severe or moderate lipoatrophy has shown an increase in limb fat by DEXA. This study was conducted over a 24-week period and although improved outcomes were documented by objective measures, DEXA scans, subjective observation did not correspond. Longer-term follow up of these patients is required. This 48 week study is designed to compare the substitution of the thymidine analogues zidovudine (ZDV) or stavudine (D4T) with either tenofovir DF or abacavir, in patients treated with highly active antiretroviral therapy (HAART), and show improved outcomes on total limb fat mass, improved body shape by dual energy x-ray absorptiometry (DEXA) and computed tomography (CT) scans and improved cholesterol and triglycerides.

Evaluate and record any changes in the Quality of Life and psychological state of the affected study group following treatment with Bio-Alcamid. Evaluate the safety and efficacy of Bio-Alcamid for restoring the natural fullness and contours of the face affected by HIV drug-induced lipoatrophy. Pre-treatment classification and post treatment recording of changes will be performed by, both, the Principal Investigator and the Treatment Specialist and independently by a 'Blinded' Co-Investigator at post treatment Week 12. Safety data for Bio-Alcamid will be collected throughout the duration of the study. Safety will be determined by the rates of procedure-related events and adverse experiences associated with the use of Bio-Alcamid.

The purpose of this study is to examine the effect of rosiglitazone on limb fat and mitochondrial indices in HIV-1-infected subjects receiving stable antiretroviral therapy that does not contain stavudine (d4T) or zidovudine (AZT).

This study is a randomised, placebo-controlled study of the effect of treatment with the HMG-CoA reductase inhibitor, pravastatin, in HIV-infected, protease inhibitor treated patients with high serum cholesterol. We hypothesise that pravastatin will result in greater reductions in cholesterol than placebo when used in conjunction with appropriate dietary advice.

This study will evaluate the safety and effectiveness of the leptin replacement therapy in treating lipoatrophy or lipodystrophy-a condition in which there is a total or partial loss of fat cells. Patients with lipodystrophy lack sufficient leptin, because this hormone is produced by fat cells. The leptin deficiency usually causes high blood lipid (fat) levels and insulin resistance that may lead to diabetes. Patients may have hormone imbalances, fertility problems, uncontrolled appetite, and liver disease due to fat accumulation. Patients 15 years and older with lipodystrophy are eligible for this study. Candidates are screened with a medical history and physical examination, and fasting blood tests. Those enrolled undergo the following additional procedures: Ultrasound of the liver and, if abnormalities are found, possibly a liver biopsy Resting metabolic rate measurement - measures the amount of oxygen breathed at rest in order to calculate how many calories are required to maintain resting body functions Magnetic resonance imaging of the liver and other organs, and of muscle and fat Estimation of body fat - measurements of height, weight, hip size, and skin folds over the arms and abdomen to estimate body fat content Insulin tolerance test - measures blood glucose levels after administration of insulin. Insulin is given through an intravenous (IV) catheter (a thin tube placed in a vein) and blood is drawn 5 minutes before the test begins, when the test begins, and 5, 10, 15, 20 and 30 minutes into the test Oral glucose tolerance test - measures blood glucose and insulin levels after drinking a glucose (sugar) solution. Blood samples are drawn through an IV catheter 15 minutes before the test begins, at the time the test begins, and 30, 60, 90 and 180 minutes into the test Intravenous glucose tolerance test - measures tissue response to insulin and glucose after glucose is injected into a vein. The glucose injection is followed by a short infusion of insulin and then blood samples are taken over 3 hours to measure insulin and glucose levels Appetite level and food intake - measures hunger level and caloric intake. Patients are questioned about their hunger level, given a variety of foods they may choose to eat and questioned again at various intervals about hunger level. On another day, patients are given breakfast (usually a milkshake) and when they want to eat again, the appetite level and caloric intake study is repeated. Hormone function tests - the function of three hormones influenced by leptin (corticotropin-releasing hormone, thyrotropin-releasing hormone and luteinizing hormone-releasing hormone) are assessed. The hormones are injected intravenously and then blood samples are drawn. When all the tests are completed, leptin therapy begins. The drug is injected under the skin twice a day for 4 months by the patient or a caregiver (similar to self-administered insulin injections for diabetes). Blood is drawn once a month to monitor the effects of treatment and drug side effects. At clinic visits scheduled 1, 2 and 4 months after therapy starts, patients have a physical examination and meet with a dietitian. Medication dosage is also increased at these visits. At the end of 4 months, all baseline studies described above are repeated. Throughout the study, all patients complete a form once a week, in which they record their symptoms. Patients with diabetes also measure their blood glucose levels at home before each meal and at bedtime.

The overall objective of this study is to assess the efficacy and safety of two dosing regimens of gemcabene (300 mg once daily for 24 weeks or 300 mg daily for 12 weeks followed by 600 mg daily for 12 weeks) in up to eight patients with Familial Partial Lipodystrophy with high triglycerides and Non-Alcoholic Fatty Liver Disease. The study will consist of a six week Wash Out Period, up to a 28 day Screening Period, a 24 week Treatment Period, and a follow-on safety assessment four weeks post final dose. Study participation will last approximately 4 months and includes at least 9 study visits, and can be as many as 11 study visits.

The purpose of the present study is to evaluate the effects of six sessions of aerobic exercise associated with shock waves therapy in the severity of gynoid lipodystrophy.

This Phase 1, randomized, placebo-controlled, double-blind, healthy volunteer study tested the safety, tolerability, and plasma pharmacokinetics of two different concentrations of TAT4 Gel administered once daily to 50 cm2 of skin for 14 days.

Lipodystrophies are rare disorders characterized by selective loss of adipose tissue and predisposition to insulin resistance and its metabolic complications. Hepatic steatosis is a common complication in patients with partial and generalized lipodystrophies.Despite aggressive management of diabetes and hyperlipidemia, hepatic steatosis and its complications present a therapeutic challenge in many patients. Due to this large disease burden, it is important to assess the efficacy and safety of novel therapies for hepatic steatosis in patients with lipodystrophies.There are, however, no systematic studies evaluating various therapeutic interventions for reducing hepatic steatosis in patients with lipodystrophies. A variety of drugs have been investigated in nonlipodystrophic patients with non-alcoholic hepatic steatosis and steatohepatitis (NASH) or non-alcoholic fatty liver disease (NAFLD). Recent data support the activation of the farnesoid X receptor (FXR, NR1H4), a nuclear hormone receptor regulated by bile acids, for treatment of NASH and NAFLD. FXR activates transcription of several genes particularly the atypical nuclear receptor small heterodimer partner (SHP, NR0B2) and thus can influence triglyceride metabolism within hepatocytes.Both cholic acid (CA) and chenodeoxycholic acid (CDCA) are ligands for FXR, however, UDCA which is the 7 hydroxy β-epimer of CDCA, does not activate FXR. Obeticholic acid (OCA) is a first-in-class selective FXR agonist which has approximately 100 fold greater FXR-agonistic activity in the nanomolar range, as compared to CDCA .It therefore appears that FXR modulation offers interesting therapeutic possibilities in treating hepatic steatosis. This study is primarily designed to study efficacy of OCA, a strong FXR ligand, in reducing hepatic triglyceride levels in patients with hepatic steatosis and Familial Partial Lipodystrophy (FPLD). If proven to be effective, it may reduce morbidity and mortality as a result of sequelae of hepatic steatosis in patients with lipodystrophies.

The study investigators' aim is to determine the long term safety and efficacy of Metreleptin (Myalept,) in promoting amelioration of metabolic abnormalities in patients with all forms of partial lipodystrophy. Patients will be offered this protocol under the following condition: Subjects have completed University of Michigan research protocol MB002-014 and have shown improved clinical benefit as judged by clinical criteria set forth in this protocol.
