Liver transplant study for liver cancer patients
This study tests a special way to preserve donated livers before transplant to see if it reduces the chance of liver cancer coming back after surgery.
Modena, MOAges 18 years+ - NCT06236633Recruiting
Blocking an artery before rectal cancer surgery
This trial tests a technique called ischemic preconditioning, where doctors temporarily block a main artery in your gut before rectal cancer surgery to see if it helps reduce complications. If you are scheduled for this type of surgery and meet the health criteria, the study may offer more information about safer recovery.
MontpellierAges 18–90 - NCT06237452RecruitingPhase 3
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.
