New drug cocktail aims to tame stubborn IBD
NCT ID NCT07487311
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether combining guselkumab with JAK inhibitors (upadacitinib or tofacitinib) can help people with inflammatory bowel disease that hasn't improved with other treatments. About 80 participants will receive the drug combination and be monitored for 12 and 52 weeks to see if their symptoms and gut inflammation improve. The goal is to find a new option for those with limited choices.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- guselkumab and JAK inhibitors (upadacitinib or tofacitinib)
- What this could lead to
- If it works, this combination could offer a new treatment option for people with inflammatory bowel disease that hasn't responded to other therapies.
- What could go wrong
- This is a small, early-phase study with only 80 participants, so results may not apply to everyone. Combining two strong drugs also raises the risk of side effects like infections.
