What this trial studies

This study evaluates the concentrations of risankizumab, a medication used for inflammatory bowel disease (IBD), in the breast milk of lactating women. It involves approximately 10 adult women who are at least 5 weeks postpartum and exclusively breastfeeding. Participants will have received at least two doses of risankizumab maintenance therapy prior to enrollment. The study will collect breast milk samples and conduct regular medical assessments over a duration of about 7 months.

Who should consider this trial

Good fit: Ideal candidates are lactating women with a diagnosis of Crohn's disease or ulcerative colitis who are receiving risankizumab treatment.

Not a fit: Patients who are not lactating or those with planned major surgeries during the study may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the safety and transfer of risankizumab through breast milk, aiding treatment decisions for lactating women with IBD.

How similar studies have performed: While studies on drug concentrations in breast milk are common, this specific assessment of risankizumab in lactating women with IBD is novel.
