Testing a malaria infection in healthy adults
This study gives healthy adults who have never had malaria a controlled infection with the parasite that causes malaria, to see if it is safe and if mosquitoes can pick up the parasite from them. It may help develop new ways to prevent malaria.
Bethesda, MarylandAges 18–54 - NCT06617091RecruitingPhase 1
HIV vaccine trial for healthy adults with and without HIV

West Palm Beach, FloridaAges 18–65 - NCT04748796RecruitingPhase 3
Landiolol to prevent death in ventilated septic shock patients
This trial tests whether landiolol (a short-acting heart-rate–lowering medicine) can reduce deaths compared with standard care in people in septic shock who have a fast heart rate and strong heart pumping. It is meant for a very specific type of critically ill patient while they are on a breathing machine.
AmiensAges 18 years+ - NCT06615232Recruiting
Vaginal washing study for cervical health
This study looks at how vaginal washing (cleaning inside the vagina) might affect inflammation in the cervix. If you wash inside your vagina, you may be able to take part and help us learn more about its effects on your body.

This study tests whether giving a baby’s own stool back to them (after it was stored before antibiotics) can help restore healthy gut bacteria. It’s for healthy infants and toddlers up to 4 years old who haven’t recently taken antibiotics.
New Brunswick, New JerseyAges 1 month–4 years - NCT06602557RecruitingPhase 2
Inhaled antibiotic for lung infection during ECMO support
This trial tests whether adding an inhaled antibiotic (amikacin) to standard IV antibiotics can better treat a serious lung infection (pneumonia caused by Gram-negative bacteria) in patients on a heart-lung machine (ECMO) and a breathing tube. If you or your loved one is on ECMO and has this type of pneumonia, this study may offer a new treatment approach.
ParisAges 18 years+ - NCT06601712RecruitingPhase 4
