About this study

Official title: Metabolism and Toxicity of Acetaminophen in Preterm Infants

The purpose of this study is to investigate how acetaminophen (APAP) is released into the urine and blood; to determine how the blood levels of acetaminophen and its breakdown products affect the preterm infant's health; to decrease adverse drug reactions; and to collect data on how the genetic make-up or characteristics affect how APAP is handled within the preterm infant. By taking several blood and urine samples during the study, we will be able to check the blood levels (called pharmacokinetics) of APAP in preterm babies.

Read the detailed description

Study procedures: The decision to replace standard intravenous morphine therapy with APAP will be made by the attending neonatologist.

Length of participation: 60 hours. No patient will be prescribed the medication specifically for the study purposes in the study protocol.

What participants receive

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

  • Acetaminophen/APAPDrug

    Also called Tylenol

    In preterm and term neonates with a GA of 28 weeks or more a 15 mg/kg dose of APAP will be given every 8 hrs by an intravenous infusion over 30-minute.

    In preterm and term neonates with a GA of less than 28 weeks a 15 mg/kg dose of APAP will be given every 8 hrs by an intravenous infusion over 30-minute

What is being measured

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

  1. primary endpoint PK analysis

    Blood and urine levels of APAP and metabolites

    Measured: 48 hours

Secondary outcomes (1)
  1. Developmental stage

    To assess both the magnitude and statistical significance of any evidence of relationship between developmental stage and toxicity-associated metabolite levels.

    The analyses will also hold constant APAP dose, BID or TID and possible confounding variables such as birth order, maternal smoking status, and maternal age. We will plot the relationship between stage of development and measures of APAP Metabolism, taken at different gestational and postnatal ages. A hierarchical, cross sectional time series models will be used.

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Acetaminophen/APAP in people with Pain, run by John van den Anker at 2 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 5 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 2 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Results are not available in the source record.

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?

primary endpoint PK analysis (time frame: 48 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 NCT01328808, which also lists 3 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 2 Mar 2022.
