Summary

This study looks at people with inflammatory bowel disease (Crohn's disease or ulcerative colitis) who are in deep remission. It compares two methods for gradually increasing the time between infliximab infusions: one based on symptoms and one based on drug levels in the blood. The goal is to see which approach better maintains remission and reduces the number of infusions needed.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
infliximab
What this could lead to
If successful, this could allow some IBD patients to receive fewer infusions while maintaining remission, reducing treatment burden.
What could go wrong
This is a small, early-stage study. Spacing infusions may increase the risk of disease flare-ups or loss of remission.
