The Ondansetron Premedication Trial in Juvenile Idiopathic Arthritis

University of British Columbia·interventional·Posted Nov 20, 2019·Updated Jun 29, 2025

In Brief

A clinical study evaluating Methotrexate, Ondansetron, and 1 other intervention for Juvenile Idiopathic Arthritis. Completed, enrolled 52 participants across 11 sites.

Detailed Summary

Far too many kids and families live in dread over the weekly nausea and vomiting caused by methotrexate - a medicine that controls joint swelling in Juvenile Arthritis patients. If methotrexate is not tolerated, expensive alternative biological medications may be started. This registry-based pragmatic randomized controlled trial will evaluate if routine premedication with the anti-emetic drug Ondansetron, reduces nausea and vomiting and increases the proportion of children able to continue methotrexate. By preventing nausea before it starts, the investigators hope to give kids and families a better quality of life and see a more cost-effective use of medication.
