Study of mother-to-baby gut germs and baby health
This study looks at how germs in a mother can be passed to her baby and whether that affects the baby’s health. If you join, your baby (and the other parent or legal guardian) may be asked to share consent so researchers can follow the pregnancy and early life.

Switching HIV treatment: 2-drug versus 3-drug plan
This trial compares two different HIV treatment plans: keeping you on a 2-drug regimen versus switching to a 3-drug regimen. It’s designed for people whose HIV is well controlled and looks at whether the switch is safe and effective.
GhentAges 18 years+ - NCT05267821RecruitingPhase 2/Phase 3
Testing anakinra to reduce inflammation in pediatric sepsis MODS
This study tests whether a medicine called anakinra can “turn down” harmful inflammation in children with severe illness from sepsis. It aims to improve organ function when multiple organs are starting to fail.
Birmingham, AlabamaAges 1 day–17 years - NCT04098133Recruiting
Tracking germs that resist key antibiotics in Swiss hospitals
This study collects and studies lab-detected germs in hospital patients that produce special enzymes making some antibiotics less effective. It helps researchers understand how these resistant germs spread over time in Switzerland.
BaselAges 18 years+ - NCT03731559RecruitingPhase 2
HIV treatment with dolutegravir plus rifampicin during TB care
This Phase 2 study tests how well and how safely an HIV medicine (dolutegravir) works when given with rifampicin, a common anti-TB medicine, for people starting HIV treatment during TB treatment. It also studies drug levels in the body to help confirm dosing and safety while treating both infections.
Bangkok, BangkokAges 18 years+ - NCT03236987RecruitingPhase 3
Clarithromycin versus azithromycin for lung MAC infection
This Phase 3 trial compares two antibiotics—clarithromycin and azithromycin—to treat lung infection caused by Mycobacterium avium complex (MAC). It may help by showing which antibiotic works better and is safer for people who need MAC treatment.
Amiens, PicardieAges 18 years+ - NCT05446571RecruitingPhase 3
Letermovir in pregnancy versus valaciclovir for fetal CMV
This trial tests whether letermovir can treat a baby’s early (first-trimester) congenital CMV infection in pregnancy, compared with the standard drug valaciclovir. The goal is to reduce serious effects from CMV while monitoring safety and pregnancy outcomes.
ParisAges 18 years+ - NCT02154035Recruiting
Measuring HIV reservoir in Ugandans with suppressed virus
This study in Uganda looks at the HIV 'reservoir' (where the virus hides in the body) in people whose HIV is already well-controlled with medications. It involves blood draws and genetic testing to learn more about the virus.
KalisizoAges 18–49 - NCT03174977RecruitingEarly Phase 1
How HIV medicine moves through the body on MRI scans
This early study measures how raltegravir (an HIV medicine) spreads in the body using a special scan called PET/MR. It may help doctors better understand how to deliver and monitor HIV treatment, even though it focuses on measuring drug behavior rather than curing HIV.
San Francisco, CaliforniaAges 18 years+ - NCT05387005Recruiting
Check who should be tested for H. pylori to prevent stomach cancer
This study looks at a screening plan to prevent stomach cancer by identifying people who should be tested and treated for H. pylori, a common stomach germ. If you have never had H. pylori testing or treatment, the trial may help determine the best approach for prevention.
TaipeiAges 20 years+ - NCT02801253Recruiting
Study of infections around hip, knee, or shoulder implants
This study follows people who have an infection around a hip, knee, or shoulder implant (prosthesis). It uses standard infection tests (like cultures and blood tests) to confirm the diagnosis and better understand this problem after surgery.
Paris, Île-de-France RegionAges 18 years+ - NCT02437981Enrolling by invitation
PrEP for HIV prevention in high-risk adults in Thailand
This trial checks how well PrEP pills (TDF/FTC) prevent HIV in people who are at high risk and are HIV-negative. It may help you understand whether PrEP is a good prevention option for your situation.
Bangkok, PathumwanAges 18 years+ - NCT00796263RecruitingPhase 3
Test HIV medicines for people with new or long-term HIV
This Phase 3 study looks at antiretroviral treatment (HIV medicines) for adults with either recent (acute) or long-term (chronic) HIV. It’s designed to see how well and safely ongoing HIV treatment works, and it may help you get structured care and monitoring.
BangkokAges 18 years+ - NCT05426499Recruiting
Modeling how pediatric anti-infective drugs behave in kids
This trial studies how certain anti-infective medicines (for bacterial and fungal infections) move through the body in children. The goal is to use that information to improve how these medicines are dosed and used safely in pediatric care.
Poznan, Greater Poland VoivodeshipAges Any age - NCT01336855Recruiting
Provide blood for studies comparing HIV groups
This study collects blood to help researchers run multiple projects, including comparing people who are HIV-negative with people who have HIV. It may help advance knowledge that could improve future testing or treatments.
San Francisco, CaliforniaAges 18 years+ - NCT01558804Recruiting
Study for children with strep throat using beta-lactam antibiotics
This study looks at children ages 5–15 who test positive for Group A strep (often called strep throat). It may help by testing an antibiotic approach with beta-lactam medicines for children who are expected to need treatment.
Madison, WisconsinAges 5–15 - NCT02096536RecruitingPhase 4
Studying how vancomycin is handled in newborns
This study looks at how the antibiotic vancomycin moves through and acts in newborn babies. It may help doctors dose the medicine more safely and effectively for babies in intensive care.
Leuven, Vlaams-BrabantAges 1 day–1.9 years - NCT00796146Recruiting
Study people newly infected with HIV to learn early changes
This study enrolls adults with a very recent (“acute”) HIV infection to follow them over time and better understand what happens early after infection. Your participation may help researchers improve how acute HIV is detected and managed.
Bangkok, BangkokAges 18 years+ - NCT05432778RecruitingPhase 2
Letermovir to prevent CMV in new heart transplant patients
This Phase 2 trial tests whether the medicine letermovir can prevent a common viral infection (CMV) after a new heart transplant. It may help reduce CMV infection or illness in people who are at moderate to high CMV risk.
LjubljanaAges 18–70 - NCT04793152Recruiting
Tested vancomycin dosing for serious MRSA using different lab targets
This trial compares two ways of dosing vancomycin (an antibiotic) for serious MRSA infections by using different blood test targets. The goal is to see if the newer approach works at least as well as the standard one, while keeping patients safe.
Hamilton, OntarioAges 18 years+ - NCT04099082Recruiting
Predicting lung scarring after a specific viral infection
This study looks at how your immune response to a particular virus (PIV) might predict future lung scarring called bronchiolitis obliterans. It may help doctors better identify who is at higher risk after a stem cell transplant.
Paris, Île-de-France RegionAges 18 years+ - NCT03893188Recruiting
SwissPrEPared program study for HIV-negative teens and adults
This study looks at people who join the SwissPrEPared program and who are HIV-negative. It tests how well the program’s steps can be followed and how participants do while enrolled.

Preventing CMV after a haploidentical stem cell transplant
This Phase 2 study tests a preventive “cell therapy” made from a donor’s immune cells to lower the risk of CMV infection after a haploidentical stem cell transplant. If you’re at risk for CMV, this may help protect you during the early post-transplant period.
