Pharmacokinetics of NRL972 in Patients With Nonalcoholic Steatohepatitis (NASH) and Non-Alcoholic Fatty Liver Disease (NAFLD)

This study has been completed.

Norgine Identifier:
First received: November 19, 2008
Last updated: June 9, 2015
Last verified: August 2010
This study is to evaluate the predictive value of NRL972 pharmacokinetics in the diagnosis of steatohepatitis using fatty liver disease as the comparator group. In addition, the sensitivity and specificity of NRL972 pharmacokinetics as a diagnostic tool will be compared to results from the standard laboratory tests, elastography, tests of metabolic markers and serum fibrosis markers frequently used in the evaluation of clinically predicted NAFLD patients. Patients will be included if they have clinical evidence of fatty liver disease and have been referred to the clinic for a diagnostic work-up, including a liver biopsy, blood tests and scans of the liver.

Further study details as provided by Norgine:

Primary Outcome Measures:
  • The primary efficacy variable is the NRL972 fractional retention ratio for 10 and 30 minutes post-dose (C30/C10) for different populations with NAFLD. [ Time Frame: 30 minutes post-dose ]

Secondary Outcome Measures:
  • Approximate overall clearance and t½ within 60 minutes of dosing with NRL972. Cmax, AUC(0-∞), and mean residence time derived from a non-compartmental analysis. [ Time Frame: 60 minutes post-dose ]

Enrollment: 125

  • Any ethnicity
  • Age: 18 to 80 years of age
  • Clinical evidence of non-alcoholic liver disease requiring the conduct of a liver biopsy for the diagnosis of NAFLD and/or staging of disease severity

  • Clinically evident rapidly deteriorating hepatic function
  • Significant bleeding diathesis
  • Esophageal bleeding within the 8 weeks prior to study entry
  • Presence of any contraindications for the conduct of the planned liver biopsy (e.g. allergy to lidocaine, coagulopathy with <100 x109/L thrombocytes and/or INR >1.3
  • History of any allergic reaction to fluorescein
  • Presence of any acute infection
  • Previous participation in this trial
  • Having received any investigational drug or treatment within 30 days prior to study entry or requiring a concurrent treatment with any other experimental drug or treatment
  • Uncontrolled hypo- or hypertension (treated or untreated) with resting systolic blood pressure >160 or < 90 mmHg, diastolic blood pressure >95 or < 50 mmHg
  • Clinically relevant abnormal laboratory values indicating end-stage renal, pulmonary or cardiac disease
  • Known HIV infection
  • Concurrent alcohol use of more than 14 drinks (140g ethanol) for men and 7 drinks (70g ethanol) for women per week (each drink is counted as 10g ethanol)

  • Use of prohibited medication (section 4.8)
  • Donation of blood during the last 60 days or a history of blood loss exceeding 300 mL within the last 3 months
  • Suspicion or evidence that the subject is not trustworthy and reliable
  • Suspicion or evidence that the subject is not able to make a free consent or to understand the information in this regard
  • Significant side effects prior to the liver biopsy (e.g. anxiety requiring pre-medication) or after the biopsy (e.g. pain requiring i.v. pain medication, bleeding re-quiring medical intervention)

General - all females

  • Positive pregnancy test
  • Pre-menopausal women not using appropriate contraception
