Testing icotrokinra for moderate to severe Crohn's disease
This study tests a new medicine called icotrokinra for people with moderate to severe Crohn's disease who have not responded well to other treatments. It aims to see if icotrokinra can help reduce symptoms and improve gut health.
Chandler, ArizonaAges 18 years+ - NCT07197944RecruitingPhase 3
Glepaglutide for short bowel syndrome
This trial tests a new medication called glepaglutide to see if it can help people with short bowel syndrome (SBS) who need IV nutrition or fluids at least 3 days a week. The goal is to reduce or even stop the need for these IV treatments.
Chicago, IllinoisAges 18–90 - NCT07193927RecruitingPhase 2
Testing a probiotic mix for fatty liver disease (MASLD)
This trial tests whether a probiotic mixture can improve liver health in people with moderate fatty liver disease (MASLD). It looks at how the probiotic affects liver fat, inflammation, and metabolism.
