VE303 to prevent repeat C. diff infections
This trial tests a new medicine called VE303, a live bacterial therapy, to prevent C. diff infections from coming back. It is for people who have had C. diff at least once in the last 6 months, or who are at high risk for a repeat infection due to age or other health problems.
Huntsville, AlabamaAges 12 years+ - NCT06236932Recruiting
Infection risk in obesity study
This study looks at how obesity and related conditions affect your body's ability to fight infections. It may help find ways to prevent illness in people with obesity.
NaplesAges 18–65 - NCT06237660Recruiting
Wheeze study for young children
This study looks at young children (ages 1-5) who have had severe wheezing episodes that needed hospital care. It aims to find biomarkers (clues in the body) that could help predict which children might develop asthma later.
LondonAges 1–5 - NCT06238297Recruiting
Testing early stopping of MRSA antibiotics for pneumonia
This trial tests whether a simple nasal swab can help doctors safely stop unnecessary MRSA antibiotics sooner in people with pneumonia. If the swab shows no MRSA, the antibiotic can be stopped early, which may reduce side effects and drug resistance.
BariAges 18 years+ - NCT06245746RecruitingPhase 1
Exosomes for low blood counts after chemo in leukemia
This trial tests whether umbilical cord mesenchymal stem cell exosomes can help restore blood cell counts after chemotherapy in adults with acute myeloid leukemia who are in remission. It aims to reduce the risk of infection and bleeding while waiting for bone marrow recovery.

Finding HDV in Turkey Study
This trial is looking for adults in Turkey who have had a hepatitis B infection (HBsAg positive) for at least 6 months. The goal is to see if they also have a hepatitis D virus (HDV) infection. This may help doctors better understand and treat these infections.
AnkaraAges 18 years+ - NCT06250985RecruitingPhase 3
New treatment for infected heart device: quick re-implant
This trial tests if a new, faster approach to replacing an infected pacemaker or defibrillator is safe. If you have a heart device infection and meet recovery milestones, you might be able to get a new device sooner than usual.
CopenhagenAges 18–110 - NCT06250023Recruiting
Oral antibiotics for spinal infection treatment
This trial tests whether oral antibiotics, taken as pills, work as well as IV antibiotics for treating spinal infections. It may be an option if your infection is already improving with a short course of IV antibiotics.
