Detailed Description
Nonalcoholic Fatty Liver Disease (NAFLD) is a condition in which fat builds up in the liver. As its name suggests, it is not associated to heavy alcohol use. Non-Alcoholic Steatohepatitis (NASH) is a condition of liver inflammation and damage that is caused by the buildup of fat in the liver. It is usually associated with prediabetes, diabetes (high blood sugar in the blood), a high concentration of fat (triglycerides) in the blood, and obesity (increase in fat all over the body). The signs and symptoms of NASH are often not seen until the liver is damaged beyond repair, making NASH very difficult to diagnose (be picked up by your doctor) in its early stages where treatments might be able to reverse the damage.
There are no treatments currently approved for people with NASH but several new medications are under study in people with NAFLD or NASH. This study uses a treatment being developed for treating NASH. The investigators will conduct a study to assess the effects of PF-05221304 (PF'1304) on the way the liver handles fat. In early studies, this new drug has shown promise for lowering the level of fat in the liver. However, it also, unexpectedly, increases the level of fat in the blood, which could increase the risk of heart disease and inflammation of the pancreas.
The planned study will identify why the fat in the blood increases. Subjects will undergo a screening period where we will obtain medical history and physical exam. Additionally, we will obtain the results of liver imaging or liver biopsy previously performed by the subject's doctor that confirm the presence of an abnormal amount of liver fat and liver stiffness. The enrolled subjects will receive placebo (an inactive pill) during the first 6 weeks, followed by a 3 week washout period and then 6 weeks of active treatment. Blood samples will be collected during outpatient visits to check for study safety and measurements of fat in the blood and particles that carry that fat. There will also be 2 long outpatient studies that last approximately 15 hours each, where we will test why there is increase in fat blood levels during treatment with PF'1304. All visits will occur at the CUIMC Irving Institute for Clinical and Translational Research. Subject risk will be minimized through strict eligibility criteria to avoid enrollment of unstable or high-risk subjects and by close monitoring of adverse events (AE's), laboratory parameters, and vital signs during the study. In addition, blood fat levels will be measured on an ongoing basis.

Description
Inclusion Criteria:
- Body mass index (BMI) of ≥ 25 kg/m2 but < 40 kg/m2 and at least 2 of 5 traits of metabolic syndrome (fasting blood glucose >100 mg/dl or diagnosis of diabetes mellitus; BP >130/85; fasting TG >150 mg/dl; HDL cholesterol <40 mg/dl for men and <50 mg/dl for women; waist circumference >101 cm for men and >89 cm for women).
- NASH will be defined as a FibroScan® of CAP >280 db/m and >7 kPa, OR demonstrated by liver biopsy, plus:
- ALT > ULN but < 5 X ULN.
- FIB4 score <3.5 (see below)
- BP of ≤ 160/100 mmHg.
- Alkaline phosphatase ≤ ULN.
- Total bilirubin ≤ ULN (unless the subject has Gilbert's syndrome, a benign genetic problem where bilirubin is not conjugated normally and indirect bilirubin (unconjugated bilirubin increases) in which case direct bilirubin must be ≤ ULN with total bilirubin > ULN).
- Platelet count ≥ LLN (155,000/mm3).
- Albumin ≥ LLN (3.0 g/L).
- INR ≤ 1.3.
- Fasting serum triglycerides ≤ 350 mg/dL either non-pharmacologically managed or pharmacologically managed with stable doses of up to 3 oral agents for at least 6 months. They may be receiving statins if the dose has been stable for at least 3 months.
- Subjects may have diabetes but must have an HbA1C ≤ 8.0% with glycemic control either non-pharmacologically managed or pharmacologically managed with stable doses of up to 3 oral agents for at least 6 months. Subjects taking a stable dose of long-acting insulin or an injectable GLP-1 inhibitor may be enrolled at the discretion of the investigators.
- No changes in drugs affecting blood lipid or glucose or insulin levels will be permitted during the study without approval by the investigators.
Exclusion Criteria:
- Individuals with a history of plasma TG >1000 mg/dl and/or pancreatitis.
- Females of childbearing potential.
- Chronic kidney disease defined by estimated glomerular filtration rate < 30 ml/min/1.73 m² by the modification of diet in renal disease equation.
- Documented chronic hepatitis B or C. Subjects with hepatitis C are eligible provided there is proof of sustained virology response (SVR) for ≥ 3 years.
- History of active malignancy within 5 years (subjects with non-melanoma skin cancer may be included).
- Any other disease, condition, or laboratory value that, in the opinion of the principal investigator or clinical study team would place the subject at an unacceptable risk or interfere with the evaluation of the investigative product.
- History of organ transplantation (other than corneal).
- History of hepatobiliary malignancy even if subject "cured".
- Pancreas divisum or a congenital abnormality of the pancreas
- History of pancreatic surgery.
- Subjects taking anti -coagulants or anti-platelet agents other than 81 mg ASA daily.
- Treatment with immunomodulators.
- Drugs associated with acute pancreatitis as asparaginase, azathioprine, didanosine, mecaptourinol, mesalamine, opiates, pentamidine, pentavalent anti-monials, valproic acid, and rifampin.
- OATP inhibitors such as gemfibrozil and cyclosporinea. Drugs substrates for CYP3A4/5 with a narrow therapeutic index - these include: alfentanil, astemizole, cisapride, cyclosporine, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, and terfenadine will be reason for exclusion.
a = the major clearance mechanism of PF-05221304 is active uptake into liver (mainly via hepatic transporters OATP1B1/1B3) followed by hepatic carbonyl reductase 1, 11b-hydroxysteroid dehydrogenase, and CYP 3A4/5-mediated metabolism. It is anticipated that potent OATP inhibitors may increase plasma concentrations of PF-05221304. As such, subjects treated with clinically relevant OATP inhibitors will be excluded from this study.
