Gut bacteria study for constipation-predominant IBS with methane
This study looks at the gut bacteria in people with irritable bowel syndrome (IBS) who have constipation and produce high levels of methane gas. It aims to understand how methane relates to symptoms and may guide future treatments.
LyonAges 18 years+ - NCT03339128RecruitingPhase 2
Eluxadoline for diarrhea-predominant IBS in children
This trial tests whether eluxadoline can reduce symptoms of IBS with diarrhea (IBS-D) in children ages 6 to 17. It also asks families to track symptoms with a daily diary to measure whether treatment helps over the study period.
Hot Springs, ArkansasAges 6–17 - NCT05803993Recruiting
Fecal transplant to ease constipation in irritable bowel syndrome
This trial tests whether transferring stool bacteria to the gut (fecal microbiota transplantation) can reduce symptoms of irritable bowel syndrome with constipation. It may help by changing the gut microbiome, but you must meet safety and health requirements.
RomaAges 18 years+ - NCT05803980Recruiting
Fecal transplant to ease IBS diarrhea symptoms
This study tests whether fecal microbiota transplantation (a stool-based treatment to change gut bacteria) can reduce symptoms of irritable bowel syndrome (IBS) that comes with diarrhea. You may be eligible if you’re an adult with diarrhea-predominant IBS and recent colonoscopy results that rule out other intestinal diseases.
RomaAges 18 years+ - NCT06727422RecruitingPhase 2
Rifaximin plus NAC for IBS with diarrhea
This trial tests whether a combination of two medications—rifaximin (a gut antibiotic) and NAC (a supplement that helps break down mucus)—can reduce belly pain and diarrhea in people with IBS whose symptoms are not well controlled. It may be an option if other treatments haven't worked well enough.
Los Angeles, CaliforniaAges 18 years+ - NCT07094035Recruiting
Green tea and probiotics for constipation-predominant IBS
This study tests whether a supplement containing green tea extract and probiotics can improve bowel function in people with irritable bowel syndrome (IBS) that mainly causes constipation. If you have chronic constipation and abdominal pain, this could help.
NaplesAges 18–70 - NCT07168434RecruitingPhase 3
Yeast supplement for irritable bowel syndrome (IBS)
This trial tests if a yeast supplement called Saccharomyces boulardii can help people with irritable bowel syndrome (IBS), except for those with constipation as their main symptom. Participants take the supplement and see if their symptoms improve.
BragaAges 18–65 - NCT07749092Recruiting
Kimchi powder for gut health in IBS
This study tests whether taking kimchi powder (a dried form of the fermented cabbage dish) can improve gut health and symptoms in people with diarrhea-predominant IBS. You'll avoid regular kimchi for about 2 months, then take the powder daily and track how you feel.
