Arms Assigned Interventions
Experimental: Acetadote without EDTA
Acetadote EF [Ethylenediaminetetraacetic Acid (EDTA) - Free]
Drug: Acetadote EF [Ethylenediaminetetraacetic Acid (EDTA) - Free]
Acetadote EF [Ethylenediaminetetraacetic Acid (EDTA) - Free] {new formulation} 200 mg/kg in 1000 ml diluent over 4 hours; then 100 mg/kg in 1000 ml diluent over 16 hours
Other Name: acetylcysteine
Active Comparator: Acetadote
Acetadote [Old formulation containing EDTA]
Drug: Acetadote
Acetadote [old formulation] 150 mg/kg in 200 mL diluent over 60 minutes; then Acetadote 50 mg/kg in 500 mL diluent over 4 hours; then Acetadote 100 mg/kg in 1000 mL diluent over 16 hours.
Other Name: acetylcysteine

Detailed Description:

The primary objective of this study is to demonstrate non-inferiority of efficacy determined by the proportion of subjects who develop hepatotoxicity when treated with a new formulation of Acetadote and the proposed new dosing regimen compared to the rate of hepatotoxicity with the current formulation of Acetadote and the current dosing regimen.

  Eligibility

Ages Eligible for Study:   12 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

1) Any subject requiring treatment with acetylcysteine for acute acetaminophen toxicity

Exclusion Criteria:

  1. History of allergy or hypersensitivity to acetylcysteine or any component of Acetadote.
  2. Exposed to investigational drugs within 30 days before Clinical Trial Material (CTM) administration.
  3. Pregnant or nursing.
  4. Less than 12 years of age.
  5. Have a baseline alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >1000 U/L.
  6. Have a baseline International Normalized. Ratio (INR) > 2.0
  7. Be on dialysis or having existing renal injury such that the volume of the study drug administration would render the patient unsuitable for the study, in the opinion of the investigator.
  8. Have congestive heart failure such that the volume of the study drug administration would render the patient unsuitable for the study, in the opinion of the investigator.
  9. Inability to understand the requirements of the study. Subjects must be willing to provide written informed consent or consent of parent/legal guardian (as evidenced by signature on an informed consent document approved by an Institutional Review Board [IRB]), and agree to abide by the study restrictions. (If the subject is incapacitated, informed consent will be sought from a legally acceptable representative).
  10. Refusal to provide written authorization for use and disclosure of protected health information.
  11. Be otherwise unsuitable for the study, in the opinion of the Investigator.
