Phase 2 Study of Obeticholic Acid for Lipodystrophy Patients

Inclusion Criteria

• Patients with familial partial lipodystrophy of the Dunnigan variety with heterozygous disease-causing missense mutation in lamin A/C (LMNA) gene.
• Hepatic steatosis (>5.6% hepatic triglyceride content) as demonstrated by 1H magnetic resonance spectroscopy.
• Age 18-70 years.
• Alcohol intake of less than 20 g per day in females and 30 g per day in males.
• Participants and their partners with whom they are having sex, must use medically-acceptable birth control (contraceptives) during the study. Medically-acceptable methods of contraception include: (1) surgical sterilization, such as hysterectomy, tubal ligation or vasectomy. (2) approved hormonal contraceptives, such as birth control pills, patch or ring; Depo-Provera, Implanon. (3) barrier methods, such as condom, cervical cap or diaphragm used with a spermicide. (4) an intrauterine device (IUD).

Exclusion Criteria

• Laboratory or other histologic findings highly suggestive of liver disease due to causes other than non-alcoholic steatohepatitis, such as chronic viral hepatitis, autoimmune hepatitis, primary biliary cirrhosis, biliary obstruction or genetic liver diseases such as Wilson's disease, hemochromatosis or alpha-1-antitrypsin deficiency.
• Treatment with drugs associated with steatohepatitis, e.g., corticosteroids, high dose estrogens, methotrexate, amiodarone, tamoxifen, valproic acid, sulfasalazine, or oxacillin for more than 2 weeks in the 6 months prior to the study.
• Decompensated liver disease as evidenced by clinical features of hepatic failure (variceal bleeding, ascites, hepatic encephalopathy etc.) and laboratory investigations (prolonged prothrombin time with INR > 1.3, hypoalbuminemia with serum albumin less than 3.0 g/dL, direct bilirubin > 1.3 mg/dL, or presence of esophageal varices etc.)
• Evidence of hepatocellular carcinoma: alpha-fetoprotein levels greater than 200 ng/ml and/or liver mass on imaging study suggestive of liver cancer.
• Use of drugs which can potentially decrease hepatic steatosis during previous 3 months; ursodeoxycholic acid, thiazolidinediones, high-dose vitamin E, betaine, acetylcysteine and choline.
• Significant systemic or major illnesses other than liver disease, such as congestive heart failure, cerebrovascular disease, respiratory failure, renal failure (serum creatinine >2 mg/dL), acute pancreatitis, organ transplantation, serious psychiatric disease, and malignancy, that could interfere with the trial and adequate follow up.
• Acute medical illnesses precluding participation in the studies.
• Known HIV-infected patient.
• Current substance abuse.
• Pregnant or lactating woman.
• Hematocrit of less than 30%.
• History of weight loss during past 3 months.
• Patients on bile acid binding resins, cholestyramine, colestipol or colesevelam.
• Hypersensitivity or intolerance to OCA or any components of its formulation.
• Failure to give informed consent 16 .Previous clinical diagnosis of diabetes mellitus or fasting blood glucose ≥ 126 mg/dL or hemoglobin A1c ≥ 6.5%.
