Trial of immune therapy for newborns with congenital CMV
This Phase 2 trial tests an immune treatment made from donor T-cells to help the body fight congenital CMV infection in newborns. It may be an option if your baby is very young, has evidence of CMV infection, and meets specific blood, kidney, and liver safety limits.

Study pause of HIV treatment in people already enrolled
This study looks at what happens when HIV treatment (ART) is intentionally paused in people who are already enrolled in a specific research study (RV254) and recently joined a protocol that included an earlier treatment pause. It may help researchers understand safety and how to manage treatment changes, but it has strict participation and consent requirements.
Bangkok, BangkokAges 18 years+ - NCT02543866RecruitingPhase 1
Fecal transplant to clear resistant gut bacteria in children
This Phase 1 study tests whether transferring stool microbiome (a fecal microbiota transplant) can help clear antibiotic-resistant bacteria living in the gut. It’s meant for children and teens who have had infections from these resistant bacteria and who can safely take the study’s planned treatment.
Seattle, WashingtonAges 7–21 - NCT02055105Recruiting
Study tests a blood test pattern in children with sepsis
This trial studies how a specific pattern in blood (called “molecular fingerprinting”) changes in children with suspected or developing sepsis. The goal is to help doctors better recognize sepsis early and understand how it progresses, which may improve care.
Phoenix, ArizonaAges 1–18 - NCT02539407Recruiting
Study drug levels in critically ill children
This trial measures how anti-infective medicines move through a child’s body while they are in the hospital or during follow-up. The goal is to better understand dosing and drug exposure in critically ill children.
ParisAges 1 day–18 years - NCT02328131Recruiting
Registry study for adults with H. pylori infection
This study is a registry that follows adults who have Helicobacter pylori (a common stomach bacteria) to learn how it’s managed in real life. It may help improve care by tracking treatments and outcomes over time.
ViennaAges 18 years+ - NCT01868373Enrolling by invitationPhase 1
Fecal transplant study for hard-to-treat C. difficile diarrhea
This Phase 1 study tests defined fecal microbiota (healthy gut bacteria) given to people with C. difficile diarrhea that didn’t go away or came back soon after antibiotics. It may help by restoring a healthier balance of gut bacteria so the infection can stop recurring.
Houston, TexasAges 18 years+ - NCT03705585RecruitingPhase 4
Check how typhoid and cholera vaccines work in adults
This study gives (or follows) typhoid and/or cholera vaccines and measures how your immune system responds. It is done in adults who are already scheduled for an upper endoscopy (EGD) and/or colonoscopy, using small tissue samples if appropriate.
Baltimore, MarylandAges 18 years+ - NCT05689034RecruitingPhase 2/Phase 3
Azvudine for early COVID-19 in higher-risk adults
This trial studies azvudine in adults with early COVID-19 symptoms to see if it can prevent the illness from getting severe. You may qualify if you’re within about 5 days of symptom start and have risk factors for worsening disease.
Beijing, Beijing MunicipalityAges 18–120 - NCT05888987Recruiting
New test for severe corneal infection diagnosis
This study tests a new method for identifying bacteria causing severe corneal infections. It may help doctors choose the right treatment faster by improving how the infection is identified from corneal samples.
ReimsAges 18 years+ - NCT07668271RecruitingPhase 4
HPV 9-valent vaccine lot consistency trial for women
This trial tests whether different batches of the HPV 9-valent vaccine work consistently. It's for Chinese women aged 18 to 30 who have not had any HPV vaccine or abnormal cervical screening results.
Zhangping, FujianAges 18–30 - NCT06075745RecruitingPhase 2
CMV Vaccine Study for Liver Transplant Candidates
This trial tests a vaccine to prevent cytomegalovirus (CMV) infection in people awaiting a first liver transplant. You may be eligible if you have never been infected with CMV and are scheduled to receive a liver transplant within the next 1 to 12 months.
Birmingham, AlabamaAges 18 years+ - NCT02998411Recruiting
Blood sample study of antibiotics in hospitalized patients
This study looks at how antibiotics move through the body in adults who are hospitalized. By measuring antibiotic levels in blood (or other body samples), the team may better understand dosing for safer, more effective treatment.
Paris, ParisAges 18 years+ - NCT03307109Recruiting
Quality of life study for adults with an infected joint implant
This study looks at how treatment affects quality of life for adults who have an infection around a joint implant. You may be asked to complete questionnaires to understand symptoms and daily well-being.
LyonAges 18 years+ - NCT03346694Recruiting
Testing a new chest dressing to prevent wound infections
This trial looks at whether a different dressing placed on the chest incision during certain heart surgeries can lower the risk of surgical wound infections. If you are having a sternotomy (a cut through the breastbone), this could help keep your incision cleaner while you heal.
Stanford, CaliforniaAges 18 years+ - NCT03083184RecruitingPhase 3
Ethanol lock solution to prevent catheter infections
This Phase 3 study tests whether a medicine-filled “lock” put into a dialysis catheter can lower the risk of infections. It is meant for people on regular dialysis with a tunnelled catheter who already have it in place.
Clermont-FerrandAges 18 years+ - NCT07142798Enrolling by invitation
14-day triple therapy for H. pylori infection
This trial tests a 14-day treatment using bismuth, amoxicillin, and a stomach acid reducer (PCAB) to see how well it clears H. pylori, a bacteria that can cause stomach ulcers. It may be an option if you have H. pylori and haven't had stomach surgery or certain serious health conditions.
Kaohsiung CityAges 18–80 - NCT07111078RecruitingPhase 1
New Flu Vaccine (Stem) with or without Booster
This trial tests a new type of flu vaccine that targets a part of the virus that doesn't change much (the stem). It is given with or without a special booster, and researchers want to see if it provides broader protection against different flu strains.
Bethesda, MarylandAges 18–50 - NCT06075979Recruiting
Microbes and spine health: a surgical study
This study looks at whether certain microbes (tiny living things) are linked to spine problems like herniated discs or narrow spinal canals. It involves people who need spine surgery, and the findings might help explain why some spines wear out faster.

Injectable HIV treatment trial for people with unsuppressed virus
This trial tests if switching to a long-acting injectable medication can help people with HIV who have trouble keeping their virus suppressed with daily pills. You would receive shots in the buttocks every few months instead of taking pills every day.
KeelungAges 18 years+ - NCT06197412RecruitingPhase 4
