About this study

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

The primary purpose of this study is determine if a new formulation of Acetadote is at least as effective as the current formulation in the prevention and treatment of acetaminophen overdose related liver injury.

Read the 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.

Being tested
Acetadote EF (Ethylenediaminetetraacetic Acid (EDTA) - Free), Acetadote
Keywords
Acetaminophen overdose; induced hepatotoxicity, liver injury

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AcetadoteDrug

    Also called acetylcysteine

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    Because the study was terminated prematurely due to lack of enrollment, there was an insufficient sample size to conduct an efficacy analysis.

    Measured: 21 hours

Secondary outcomes (4)
  1. To Evaluate the Percentage of Subjects Requiring Continued Therapy

    Because the study was terminated prematurely due to lack of enrollment, there was an insufficient sample size to conduct an efficacy analysis.

    Measured: 21 hours

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

    Because the study was terminated prematurely due to lack of enrollment, there was an insufficient sample size to conduct an efficacy analysis.

    Measured: 42 hours

  3. To Evaluate the Incidence of Treatment Emergent Adverse Events

    Measured: 21-42 hours

  4. To Evaluate the Incidence of Anaphylactoid Reaction.

    Data analysis was conducted on the subjects enrolled in the study prior to study termination. Because the study was terminated prematurely due to lack of enrollment, there was an insufficient sample size to conduct an efficacy analysis.

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Acetadote EF (Ethylenediaminetetraacetic Acid (EDTA) - Free) and Acetadote in people with Acetaminophen Overdose, run by Cumberland Pharmaceuticals at 14 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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 (time frame: 21 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01118663, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2014.
