Trial summary

5-HT3 antagonists (ondansetron) are highly effective medications for the treatment of nausea and vomiting. However, these medications also associated with potentially severe and life-threatening cardiac adverse drug reactions (ADRs), particularly QT prolongation. Read more about this study

About this study

Official title: 5-HT3 Antagonists (Antiemetics) and Cardiac Safety Using an Active Surveillance Approach

5-HT3 antagonists (ondansetron) are highly effective medications for the treatment of nausea and vomiting. However, these medications also associated with potentially severe and life-threatening cardiac adverse drug reactions (ADRs), particularly QT prolongation. Data regarding the cardiac safety and inter-individual variability in cardiac effects of ondansetron when used in vulnerable populations such as children and pregnant women are very limited. The results of this study will enable better-informed therapeutic decision-making regarding the use of ondansetron in children and pregnant women, with the overall goal to improve the safety of these commonly used antiemetic medications. Furthermore, predictive pharmacogenetic markers of severe 5-HT3 antagonist toxicity could be used to identify patients at risk of cardiac toxicity before the drug is administered.

Read the detailed description

The specific objectives are to:

  1. Determine and compare the cardiac safety profile of ondansetron in children, when used for prevention and management of post-operative nausea and vomiting and chemotherapy induced nausea and vomiting. Identify clinical factors including pre-existing cardiac conditions or physiological conditions that predispose to ventricular arrhythmias, concomitant cardiotoxic chemotherapy or concomitant volatile anaesthetic agents and investigate their impact on cardiac adverse effects of ondansetron.
  2. Determine and compare the cardiac safety profile of ondansetron when used in pregnant women or women of a reproductive age for the treatment of hyperemesis gravidarum or post-operative nausea and vomiting. Identify clinical factors including pre-existing cardiac conditions or physiological conditions, which predispose to ventricular arrhythmias that may support implementation of risk mitigation actions.
  3. Identify genetic variants associated with 5-HT3 antagonist-induced prolongation of QT interval.

Questions about this trial

What is this clinical trial studying?

An observational study of Adverse Reaction to Other Drugs and Medicines, run by University of British Columbia at 1 site in Canada.

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 2 inclusion and 2 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: finished, as of the sponsor's last update on 14 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Identify clinical and genetic variants associated with ondansetron-induced prolongation of QT interval (time frame: Up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 May 2021.
