I. Determine the safety and efficacy of a short course (72 hours) of intravenous acetylcysteine in patients with acute liver failure for whom no antidote or specific treatment is available.
|Condition or disease||Intervention/treatment||Phase|
|Acute Liver Failure||Drug: N-acetylcysteine (NAC) Drug: Placebo||Phase 3|
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has indicated that access to an investigational treatment associated with this study is available outside the clinical trial.
