BCAA vs. Rifaximin to Prevent Recurrent Hepatic Encephalopathy
This trial compares two treatments—BCAA supplements and rifaximin—to see which is better at preventing another episode of confusion or coma in people with cirrhosis who have already had one. If you qualify, you would receive one of these treatments for several months.

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+ - NCT07209371RecruitingPhase 2
Rifaximin vs no treatment for early blood protein disorder
This study tests whether an antibiotic called rifaximin can lower the abnormal protein levels in people with MGUS (a condition that can sometimes lead to blood cancers). If it works, it might help keep MGUS from getting worse.
Seattle, WashingtonAges 18 years+ - NCT07285785RecruitingPhase 4
Rifaximin for children with acute diarrhea
This study tests whether a medicine called rifaximin, taken along with oral rehydration solution, helps children aged 6 to 11 recover faster from acute (short-lasting) diarrhea that is likely caused by a bacterial infection. The study compares rifaximin plus oral rehydration versus oral rehydration alone.
Lynwood, CaliforniaAges 6–12 - NCT06772064Recruiting
Rifaximin for bloating caused by SIBO
This study tests whether the antibiotic rifaximin can relieve bloating in people with small intestinal bacterial overgrowth (SIBO). If you have chronic bloating and a positive SIBO breath test, this trial may be a good fit.
Jinan, ShandongAges 18–70 - NCT06058572RecruitingPhase 2
Rifaximin for gut bacteria after stem cell transplant in leukemia
This trial tests whether the antibiotic rifaximin can help protect the healthy bacteria in your gut after a stem cell transplant for acute leukemia. It may reduce infections and other complications during your recovery.
Navi Mumbai, MaharashtraAges 18–70 - NCT05677282RecruitingPhase 4
Single-dose antibiotics for sudden watery diarrhea
This trial compares rifaximin or azithromycin (both antibiotics) taken as a single dose, with loperamide to control symptoms. It’s for people with recent, watery diarrhea who can be treated and followed as an outpatient, to see which option works better and is safer.
DjiboutiAges 18–60 - NCT06743464Recruiting
Rifaximin before liver transplant for better early liver function
This trial tests whether taking the antibiotic rifaximin just before and after a living-donor liver transplant can help prevent early problems with the new liver. It may be an option for adults having this surgery at the study hospital.
New Delhi, National Capital Territory of DelhiAges 18 years+ - NCT07185932RecruitingEarly Phase 1
Rifaximin for fatty liver with metabolic issues
This trial tests if rifaximin, a gut-targeted antibiotic, can help people with fatty liver disease who also have metabolic problems like obesity or diabetes. You need a recent fatty liver diagnosis and a liver fat level of at least 8% on an MRI scan.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07381257RecruitingEarly Phase 1
Rifaximin for fatty liver disease
This trial tests if rifaximin, a gut medication, can help reduce liver fat in people with metabolic fatty liver disease. It may be an option if you have at least one metabolic risk factor and a certain amount of liver fat.
ShanghaiAges 18–75 - NCT05587036RecruitingPhase 2/Phase 3
Rifaximin study to see how gut bacteria affect mood
This trial tests whether a gut-targeting antibiotic called rifaximin changes the gut microbiome (gut bacteria) and affects emotion. It is looking for healthy men so any mood or gut changes can be more clearly linked to the study treatment.
LeuvenAges 18–50 - NCT06312683RecruitingPhase 4
Rifaximin to prevent pouchitis from coming back
This trial tests whether the antibiotic rifaximin can prevent pouchitis from coming back after a first episode. It is for people who had ulcerative colitis, have a J-pouch, and developed pouchitis within the first year after their final surgery.
New York, New YorkAges 18–74 - NCT04043897RecruitingPhase 2
Oral rifaximin for active microscopic colitis flare
This trial tests whether an oral antibiotic called rifaximin can improve symptoms during a microscopic colitis flare. It aims to see if it is safe and effective for people whose colitis was confirmed by colon biopsy.
Evanston, IllinoisAges 18 years+ - NCT04073290RecruitingPhase 4
Rifaximin and lactulose to prevent confusion after TIPS
This trial studies whether taking rifaximin plus lactulose can prevent a brain problem called hepatic encephalopathy (confusion) after TIPS, a procedure to reduce pressure in the liver. It may help people who are having TIPS planned and are at risk of this complication.
LeuvenAges 18–80 - NCT06652087Recruiting
Testing rifaximin for heart failure with preserved pumping
This trial tests whether the antibiotic rifaximin (taken by mouth) can improve heart function in people with a type of heart failure where the heart pumps well but is still weak (HFpEF). Rifaximin might help by changing the bacteria in your gut.

Richmond, VirginiaAges 65 years+ - NCT06298409RecruitingPhase 1
Rifaximin for SIBO: Gut Bacteria Study
This study tests how Rifaximin (a medicine for SIBO) affects the bacteria and other substances in your gut. You'll swallow a small capsule that collects samples as it travels through your digestive system, so researchers can see how your gut changes during treatment.
Mountain View, CaliforniaAges 18–80 - NCT04161053RecruitingPhase 3
Nitazoxanide to prevent repeat liver brain episodes
This Phase 3 trial tests whether nitazoxanide can help stop hepatic encephalopathy (a “liver-to-brain” confusion problem) from coming back. It’s for adults with cirrhosis who have had at least one past episode, aiming to improve safety and prevent recurrence.
TantaAges 20–65 - NCT06483737Recruiting

Common questions
- Are there clinical trials studying Rifaximin?
- Yes. Clin2 currently lists 20 recruiting studies that include Rifaximin, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Rifaximin trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Rifaximin an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Rifaximin or a specific trial is right for you.
