A Multi-center Study of the Safety and Efficacy of N-acetylcysteine in the Treatment of Acute Liver Failure in Pediatric Patients Not Caused by Acetaminophen.

We have completed patient enrollment in the the double blind, randomized, placebo-controlled trial of intravenous (IV) N-acetylcysteine (NAC) vs. placebo for the treatment of non-acetaminophen ALF. The purpose of this study is to examine the safety and efficacy of intravenous NAC in children with ALF for whom no antidote or other specific treatment is available. Inclusion in the NAC Study required enrollment in the Pediatric Acute Liver Failure (PALF) Study Registry.

The Pediatric Acute Liver Failure (PALF) Study Group to identify, characterize, and develop management strategies for infants, children and adolescents who present with acute liver failure. The PALF study group includes 20 sites (17 in the United States, 2 in the United Kingdom, and 1 in Canada). The primary objective of the Pediatric Acute Liver Failure (PALF) study is to collect, maintain, analyze, and report clinical, epidemiological, and outcome data in children with ALF, including information derived from biospecimens.

Patients enrolled in the PALF study registry were able to enroll in the NAC study providing they met the additional required inclusion/exclusion criteria.

Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
  • Acute Liver Failure
  • Hepatic Encephalopathy

Inclusion Criteria:

  • Meet entry criteria for and be enrolled in the Pediatric Acute Liver Failure prospective database.
  • Able to be evaluated and initiate treatment within the first 24 hours of hospitalization
  • Patients transferred from referring hospitals to the study site may be considered for enrollment, provided that no other treatment protocol has begun, and that no liver support device (BAL, ELAD, transgenic pig perfusion) has been used or is contemplated.
  • Use of fresh frozen plasma infusions will not disqualify patients from participation.

Exclusion Criteria:

  • older than 18 years of age
  • pregnancy
  • ALF that is secondary to acute APAP toxicity, mushroom poisoning, or a known malignancy.
  • Patients who exhibit signs of cerebral herniation, have intractable arterial hypotension, require inotropic drugs, or demonstrate signs of sepsis (temperature ≥ 39.5o C or bacteremia) at the time of enrollment
  • No exclusion will be made on the basis of race, ethnic group or gender.
  • Criteria for inclusion of females and minorities will be those established in the NIH guidelines
