The purpose of this study is to determine if established parenteral nutrition (PN) associated liver disease can be reversed or its progression halted by using a parenteral fat emulsion prepared from fish oil as measured by normalization of serum levels of hepatic enzymes and bilirubin.

Condition Intervention Phase
Parenteral Nutrition Associated Liver Disease PNALD Cholestasis Drug: Omegaven™ Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective Evaluation of a Parenteral Omega-3 Fatty Acid Preparation (Omegaven™) in Therapy of Patients With TPN-Induced Cholestasis

Primary Outcome Measures:
  • Progression to small bowel transplantation. [ Time Frame: Bi-weekly x4, then monthly ]
    Whether or not the subject had an intestine-containing transplant or not

Secondary Outcome Measures:
  • To determine if established PN associated liver disease can be reversed or its progression halted by using a fish oil parenteral emulsion as measured by normalization of serum levels of hepatic enzymes and bilirubin. [ Time Frame: weekly x 4, then bi-weekly x4, then monthly ]
    Serial monitoring of liver lab values to follow the biochemical progression or regression of liver disease associated with PN.

Enrollment: 85
Study Start Date: April 2009
Study Completion Date: August 2017
Primary Completion Date: August 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Omegaven™
This study will be a prospective, non-randomized, open-label study of Omegaven™ for provision of parenteral lipid calories. The study cohort, receiving the PN lipid at 1g/kg/day, will be compared to historical controls at UNMC where parenteral lipid calories were provided exclusively through soybean-based formulations. The study is planned to enroll 100 patients. The Intestinal Rehabilitation Program at UNMC sees between 20 and 30 new pediatric patients per year, with almost all being PN-dependent and over 75% presenting with a bilirubin ≥ 2mg/dL. Based on these calculations, we estimate 4-5 years to enroll 100 patients.
Drug: Omegaven™
10% Omegaven™, 50 or 100 mL bottle; 1gram/kg/day and is infused over 12-24 hours.
Other Name: Omega-3 fat emulsion

Detailed Description:
The primary objective of this study is to evaluate the need for and time to small bowel transplantation or liver transplantation. This will be calculated as both the age at time of primary transplant as well as the length of time from initial evaluation to transplant.Secondary objectives are to determine if there are improvements in clinical measures associated with established parenteral nutrition- associated liver disease (PNALD). These will be determined by measurement of total and direct bilirubin levels, platelet count, serum albumin, and changes in both length and weight growth curves.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must be enrolled in the Intestinal Rehabilitation Program at the University of Nebraska Medical Center, AND:
  • Be unable to meet nutritional needs solely by enteral nutrition and be expected to require PN for at least another 30 days
  • Have clinical evidence of parenteral nutrition associated liver disease (PNALD) as defined as a direct bilirubin of 2 mg/dl or more. A liver biopsy is desirable but not necessary for treatment
  • Signed patient informed consent

Exclusion Criteria:

  • Parent or guardian or child unwilling to provide consent or assent
  • Inability or unwillingness on the part of parent/guardian or child to follow clinical recommendations of the Intestinal Rehabilitation Program
  • Allergies or clinical conditions precluding safe use of Omegaven™
