Fecal transplant to change gut bacteria in C. difficile infection
This trial studies whether fecal microbiota transplantation (a procedure that transfers healthy stool bacteria) can change a person’s gut bacteria after repeated C. difficile infection. It may help reduce recurring infections by restoring a healthier balance of gut microbes.
RomaAges 18–90 - NCT05711446Recruiting
Studying repeat urine leaks and bladder infections after kidney transplant

Reducing infection risk after gum and tooth issues
This study looks at ways to lower the risk of infective endocarditis, a serious heart infection that can happen after certain bacteria enter the bloodstream from the mouth. You may be asked to pause routine dental cleanings for a period while they track dental health and infection risk.
Boston, MassachusettsAges 18 years+ - NCT05743374Recruiting
Diet changes with micronutrients for ulcerative colitis
This trial looks at whether changing your diet with certain vitamins or minerals (micronutrients) and other diet additives can improve health in people with moderately active ulcerative colitis. You may be asked to follow a specific diet plan, while your symptoms and medication stability are monitored.
Malmö, Skåne CountyAges 18 years+ - NCT05729256Recruiting

Tracking hospital infections and germs from nose and rectum swabs
This trial monitors healthcare-associated infections and antibiotic resistance by collecting swabs from the nose and rectum while you are hospitalized. It may help doctors better understand how often these infections happen and how to prevent them.
Philadelphia, PennsylvaniaAges Any age - NCT05711485Recruiting
Platelet-directed whole blood transfusion for malaria in young children
This study is testing a new way to use whole blood transfusions to treat severe malaria in young children. It might help children with very low platelet counts and low hemoglobin recover better.
Baltimore, MarylandAges 1 month–4.9 years - NCT05736354Recruiting
Study causes of problems after breast implants
This study looks at why breast implants can lead to complications and what those problems may involve. You may be asked to let researchers collect information and tissue or fluid samples when you have your implant removed or another breast surgery.
Carmel, IndianaAges 18 years+ - NCT05723653Recruiting
Cell phone social support for people not in HIV care
This study tests a social support intervention delivered through a “support person” (a confidant) to help people stay engaged in HIV care and improve viral suppression. It may help by strengthening support outside of clinic visits and making care easier to follow.
Birmingham, AlabamaAges 18–49 - NCT05735717RecruitingPhase 2
T-cell transplant using depleted receptors for blood cancers
This Phase 2 study tests a specialized stem cell transplant that removes certain immune “T-cell” receptors to help treat blood cancers like acute leukemia. It may help your body rebuild a healthier immune system after high-dose treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT05566483Recruiting
Study long COVID physiology and cardiopulmonary rehab effects
This study looks at how long COVID affects the body and whether cardiopulmonary rehabilitation improves quality of life and physical function. It may help participants better understand their symptoms and see if a structured rehab program improves daily abilities.
Aurora, ColoradoAges 18 years+ - NCT05674643Recruiting
Gastric testing during children’s surgery
This trial studies how the stomach is working in children around the time of surgery. It may help improve how doctors assess and manage stomach function to make surgery safer and more comfortable.
Boston, MassachusettsAges 2–18 - NCT05690841RecruitingPhase 3
Medication campaign to eliminate malaria in nearby villages
This Phase 3 trial tests whether giving malaria medicine to people in high-risk households (a “mass drug administration” campaign) can stop local relapses and eliminate vivax malaria. If you live close to a recent malaria case, you may be offered a preventive dose, based on age and medical safety checks.
IquitosAges Any age - NCT05694637Enrolling by invitationPhase 4
Support to help daily smokers with HIV stay abstinent
This Phase 4 study tests a smoking-quit support approach (reinforcement and coaching) to help people with HIV stop smoking and stay smoke-free. It may help improve smoking abstinence while you continue HIV care.
Francistown, Central DistrictAges 18 years+ - NCT05708508RecruitingPhase 3
Immune-guided vs universal medicine to prevent CMV after kidney transplant
This study compares two strategies to prevent a viral infection called CMV after kidney transplant. It tests whether an “immune-guided” approach (using your immune test results) can prevent CMV as well as or better than giving preventive antiviral medicine to everyone.
RouenAges 18–75 - NCT05674175RecruitingPhase 1/Phase 2
