What this trial studies

This observational study focuses on pregnant women who are being treated with non-anti-TNF agents or targeted small molecules for inflammatory bowel disease (IBD). It aims to gather data on the safety of these medications during pregnancy and breastfeeding, as this population is often excluded from clinical trials. The study will include patients from over 60 centers across Spain, although the expected number of participants is relatively low. All eligible patients who consent will be enrolled without a predetermined sample size.

Who should consider this trial

Good fit: Ideal candidates are pregnant women over 18 years old diagnosed with IBD who are being treated with non-anti-TNF biologics or advanced therapies.

Not a fit: Patients who do not accept to participate in the study will not benefit from the findings.

Why it matters

Potential benefit: If successful, this study could provide crucial safety data that informs treatment decisions for pregnant women with IBD.

How similar studies have performed: While this study addresses a critical gap in knowledge, similar observational studies have shown success in gathering safety data for medications in special populations.
