Cell therapy for hepatitis B–related liver cancer
This Phase 1/2 study tests a lab-made cell treatment (SCG101) for people with hepatitis B–related liver cancer who have already had standard treatments. It aims to shrink tumors and improve outcomes in carefully selected patients.
New York, New YorkAges 18–70 - NCT05319067Recruiting
Gut bacteria study in toddlers on long-term reflux antibiotics
This study compares gut bacteria (microbiome) in toddlers who take an antibiotic to prevent urine infections for vesicoureteral reflux, versus other similar children. It may help researchers understand how long-term antibiotic use and reflux affect gut health and future risk.
MontpellierAges 1–3 - NCT05571722RecruitingPhase 4
Antibiotic prevention for surgical site infections
This trial tests whether using linezolid or vancomycin before surgery can better prevent infections at the surgical wound in people at higher risk. You might be considered because you either can’t take certain standard antibiotics (beta-lactams) and/or may carry MRSA bacteria.
MarseilleAges 18 years+ - NCT05734391Enrolling by invitation
Tracking hospital infections and germs from nose and rectum swabs
This trial monitors healthcare-associated infections and antibiotic resistance by collecting swabs from the nose and rectum while you are hospitalized. It may help doctors better understand how often these infections happen and how to prevent them.
Philadelphia, PennsylvaniaAges Any age - NCT05268120Recruiting
Treatment to clear MRSA in people with difficult carriage
This study tests ways to get rid of MRSA bacteria in the body when it is “complicated,” such as having MRSA outside the nose or an ongoing MRSA infection. It may help reduce future MRSA problems or infections by lowering how long the bacteria stay in your body.
LeidenAges 18 years+ - NCT05264259Recruiting
Monoclonal antibodies for BK virus infection
This study tests a new treatment using lab-made antibodies to treat BK virus infection. It may help by controlling the virus in adults who already test BK positive.
StrasbourgAges 18 years+ - NCT05403047RecruitingPhase 4
Preventing mom-to-baby hepatitis B with tenofovir
This study tests whether the medicine tenofovir disoproxil can help prevent passing hepatitis B from mother to baby during pregnancy. It is for pregnant women with an active hepatitis B infection who are early in their pregnancy (less than 24 weeks).
TokonbéréAges 16 years+ - NCT05453513Recruiting
Study how depression and cannabis affect the brain in young adults with HIV
This study looks at brain activity to understand how depression and cannabis use may be linked in young adults living with HIV. It mainly involves questionnaires, mental health screening, and brain scans, which may help researchers better understand risk factors and brain “underpinnings.”
Miami, FloridaAges 18–59 - NCT05368571Recruiting
CHOICES program for teens at risk of pregnancy and STIs
This trial tests a teen-focused program (called CHOICES) to help reduce risky situations that can lead to pregnancy and sexually transmitted infections (STIs). It includes girls ages 14–19 who report recent risk behaviors around sex, condom use, and birth control.
Houston, TexasAges 14–19 - NCT05381194RecruitingPhase 4
Tested medicines for drug-resistant lung tuberculosis
This trial studies a specific drug combination (BPaLM) for adults with drug-resistant pulmonary (lung) tuberculosis. If you qualify, the goal is to see whether this treatment is effective and safe for your type of infection.
Seoul, Songpa-guAges 19 years+ - NCT05276557RecruitingPhase 3
Kids study of a breath test to check H. pylori
This Phase 3 study tests whether a urea breath test (a safe breath test) works well and is safe for children ages 3–17. It may help doctors find and manage an H. pylori infection without using repeated samples.
Doral, FloridaAges 3–17 - NCT05384145Recruiting
Improve HIV testing and follow-up in Alabama clinics
This trial is testing a “whole-people” plan to help more people get HIV tested, get connected to care, and stay on treatment. It is mainly for healthcare and community staff in specific Alabama counties.
Birmingham, AlabamaAges 13 years+ - NCT05350865Recruiting
Thailand study of long-term hepatitis B infection
This study follows adults with long-term (chronic) hepatitis B to better understand the condition over time. If you have chronic hepatitis B, it may help researchers improve care for people with the infection.
Bangkok, BangkokAges 18 years+ - NCT05550298Recruiting
Study of virus infections after pediatric transplants
This study looks at how respiratory viruses behave and how the body responds in children who are about to receive, or have recently received, a transplant. It may help doctors better diagnose and treat viral infections in transplant patients by studying blood samples and test results.
Birmingham, AlabamaAges Up to 18 years - NCT05575024Recruiting
Monitoring blood pressure and heart rhythm during kidney support in sepsis
This study looks at how stable blood pressure and heart rhythm are in people with sepsis who need continuous kidney filtration. If you qualify, it may help researchers better improve care for critically ill patients receiving this treatment.
SeoulAges 18 years+ - NCT05597540RecruitingPhase 3
Shorter antibiotics for kidney transplant kidney infections
This study compares giving antibiotics for 7 days versus 14 days to treat acute kidney infections (pyelonephritis) in people with kidney transplants. It aims to see if the shorter course works just as well and is safer or easier to complete.
BordeauxAges 18 years+ - NCT07226492Recruiting
Cash payments for pregnant women with HIV
This study provides cash payments to pregnant women with HIV who are living on a low income in Botswana. It aims to see if extra money can help improve health outcomes for both mother and baby.
GaboroneAges 18 years+ - NCT05505110RecruitingEarly Phase 1
Vaginal seeding to change a baby’s early gut microbes
This early-phase study looks at whether swabbing a mother’s vagina during a planned C-section (“vaginal seeding”) can help shape a newborn’s early respiratory and gut microbes. The goal is to see if this approach is safe and may influence early-life breathing health.
Nashville, TennesseeAges 18–40 - NCT05143307Enrolling by invitationPhase 1
Follow-up study for adults who received EBT-101 for HIV
This study checks how adults are doing long-term after receiving an HIV treatment called EBT-101 in an earlier study. It helps researchers understand safety and longer-term effects over time.
San Francisco, CaliforniaAges 18 years+ - NCT04979728Recruiting
Check whether home blood drops work for HIV monitoring
This study tests whether people with HIV can safely collect small blood samples at home using finger-pricks and devices (“dried blood spots”). It may help make HIV monitoring easier and more convenient while on certain HIV medicines.
Aurora, ColoradoAges 18 years+ - NCT05159739Enrolling by invitation
Study of family genetic risk for joint implant infections
This study looks at whether certain families have a higher genetic risk for infections around joint implants. It may help researchers understand who is more at risk and how to prevent these infections.

COVID-19 in blood cancer patients
This study looks at COVID-19 in people who have (or have had) blood cancers and are positive for SARS‑CoV‑2. It may help doctors understand how COVID-19 affects people with blood cancers and guide care.

Review of side effects after phage treatment for bone infections
This study looks back at people who were treated with phage therapy for a bone, joint, or implant infection and later had a side effect. It aims to better understand how safe phage therapy is in real-life use.

- What does “Infections” cover here?
- Bacterial, viral, and other infections — from common illnesses to emerging threats. We group each study into infections based on the conditions it studies, so you can scan the whole therapeutic area at once and drill into a specific condition.
- How do I find a infections trial near me?
- Use the search to filter infections studies by location and eligibility. Every Clin2 trial page explains the criteria in plain English and offers a short, optional pre-screen for a fit read — the study team makes the final decision.
