New registry tracks IBD drug risks for moms and babies
NCT ID NCT06337565
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study will follow 1,000 pregnant women with inflammatory bowel disease (IBD) who are taking newer medications (non-anti-TNF biologics or targeted small molecules). Researchers will track serious infections and other adverse events in mothers and their children up to 4 years old. The goal is to fill a critical gap in safety data, since pregnant women are typically excluded from drug trials.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide much-needed safety data on newer IBD drugs during pregnancy, helping doctors and patients make informed treatment decisions.
- What could go wrong
- This is an observational registry, not a controlled trial, so it can show associations but not prove cause and effect. The number of participants may be small, limiting the strength of conclusions.

Who is studied
This is an observational study where pregnant women treated with non-anti-TNF agents or targeted small molecules approved for IBD treatment will be included. Although it is a multicentre, nationwide study, the number of patients to be included is expected to be relatively low (in DUMBO 1, during 5 years of recruitment, 88 patients treated with ustekimunab, 34 treated with vedolizumab, and 2 exposed to tofacitinib were included); however, this registry involved over 60 Spanish centres and it is a paramount study providing with data on the safety of drugs during pregnancy, as patients with this condition are excluded from clinical trials. In this regard, no sample size estimation was made, as we plan to include all patients who meet the inclusion criteria and consent their enrolment.
