Clinical Details

Official title: A Multi-center, Double-blind, Randomized, Controlled Study to Determine the Efficacy and Safety of a New Formulation of Acetylcysteine Injection

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The Incidence of Hepatoxicity as Measured by the Percentage of Subjects With an Alanine Transaminase (ALT) or Aspartate Transaminase (AST) Value > 1000 U/L Versus Those With an ALT and AST < 1000 U/L

Secondary outcome:

To Evaluate the Percentage of Subjects Requiring Continued Therapy

To Evaluate the Incidence of Clinical Need for Therapy Beyond the Current 21 Hour FDA Approved Dosing Regimen.

To Evaluate the Incidence of Treatment Emergent Adverse Events

To Evaluate the Incidence of Anaphylactoid Reaction.

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.


Minimum age: 12 Years. Maximum age: N/A. Gender(s): Both.


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.
