Testing antibiotic dose levels for MAC lung infection
This trial studies how much medicine is needed (based on lab results) to treat MAC lung disease, an infection in the lungs. If you already have MAC and are receiving the recommended core antibiotics, your care may help researchers link treatment details to lab measurements.
ShanghaiAges 18 years+ - NCT05422508RecruitingPhase 2
Second chickenpox shot for healthy kids after one prior vaccine
This study gives a second chickenpox vaccine dose to healthy children who were vaccinated once before. It mainly checks safety and measures the body’s immune response to see how well the second dose works.
AnsanAges 4–6 - NCT06226441Recruiting
Aminoglycoside antibiotics for sepsis with low kidney function
This study tests how well aminoglycoside antibiotics work in people with sepsis who also have low kidney function. It may help find the best way to treat serious infections in patients with kidney problems.
Larissa, ThessalyAges 18 years+ - NCT07854288Recruiting
Shoulder exercises with or without massage for frozen shoulder
This study compares two types of physical therapy for frozen shoulder (a condition where the shoulder becomes stiff and painful). It looks at whether adding a specific massage technique to a standard joint exercise gives better results than the exercise alone.
LahoreAges 40–60 - NCT07856225Recruiting
Breast cancer outcomes by tumor type
This study looks at how different types of breast cancer respond to treatment. It reviews medical records of patients treated at a specific hospital to understand outcomes better.
Bogotá, Bogota D.C.Ages 18 years+ - NCT03962920Recruiting
Personalized care for urologic cancer based on gut and urine bacteria
This study looks at how your body’s bacteria (microbiome in and around the urinary/genital area) may help guide personalized treatment for localized urologic cancers. The goal is to see whether tailoring treatment to your bacteria could improve outcomes.
RoskildeAges 40–70 - NCT05285735Recruiting
Safety study for IV artesunate during pregnancy
This study follows people who were pregnant while receiving IV artesunate to better understand the treatment’s safety for both the mother and the baby. It does not test a new treatment—it collects safety information from real-world care.
Piscataway, New JerseyAges 15–100 - NCT05616546RecruitingPhase 4
Study of immune responses during and after flu infection
This study looks at how your immune system (your body’s infection-fighting system) responds during and around the time of a flu illness. It’s meant to help researchers better understand immune changes in healthy adults and may guide future flu care.
Atlanta, GeorgiaAges 18–64 - NCT03225586Recruiting
Study of health differences in urban and rural communities
This study enrolls consenting adults to understand how health differs between people living in cities versus rural areas. Your participation may help researchers learn what factors influence health over time.
Rosario, Santa Fe ProvinceAges 35–70 - NCT05971537RecruitingPhase 4
Antibiotic lock treatment for repeat peritonitis in catheter patients
This trial studies using an “antibiotic lock” inside a Tenckhoff catheter to prevent relapsing or repeat peritonitis in people on peritoneal dialysis. It may help stop infections that come back soon after antibiotics, especially when the same germ is causing them.
Tai PoAges 18 years+ - NCT05824442Recruiting
Testing a new PCR test for echinococcosis diagnosis
This study checks whether a new lab test (a PCR blood/tissue test) can more accurately diagnose echinococcosis. It may help doctors confirm the infection faster and more reliably so you can get the right treatment.
BesançonAges 18 years+ - NCT04807712Recruiting
Testing a pertussis workup for children at home visits
This trial studies children who might have pertussis (“whooping cough”). It looks at children in outpatient/home-care settings when the child’s doctor suspects pertussis and orders a lab test, to help guide evaluation and care.
CréteilAges 1 day–18 years - NCT04653610Recruiting
Study immune signals in untreated HIV using extra samples
This study looks at tiny cell “messengers” in blood and stool to understand how HIV behaves before and after starting treatment. You may be eligible if you have untreated HIV (or you’re a healthy volunteer) and can commit to many sample visits, including long-term storage for 20 years.
Ghent, Oost-VlaanderenAges 18–65 - NCT04471493Recruiting
Study of children’s common infections in a clinic program
This trial is for children under 16 who have one of several common infections seen in outpatient or clinic visits. It aims to better study and manage these illnesses using a specific clinical documentation software.
CréteilAges 1 day–16 years - NCT07866118Recruiting
Immune recovery treatment for adults with sepsis
This study tests a medicine called thymalfasin, which may help the immune system recover in adults with sepsis (a severe infection that causes organ damage). It aims to see if this treatment can improve immune function and possibly outcomes.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05756582Recruiting
Screening for hidden TB infection in hospital staff and students
This trial checks hospital workers and certain medical students to see how many have “latent TB,” meaning TB bacteria in the body that may not cause symptoms. The goal is to better understand who might need follow-up and prevention.
RomaAges 18–72 - NCT05215704Recruiting
Lab study of dormant HIV using samples from you
This trial collects blood samples from people living with HIV to study dormant (inactive) HIV cells in the lab. The goal is to better understand how to target these hidden cells as part of an eventual cure.
RotterdamAges 18 years+ - NCT05638724Recruiting
Long COVID health registry for people of all ages
This study builds a health registry to learn how long COVID affects children, teens, and adults over time. It may help by improving understanding of symptoms and care, even if it does not test a new drug.
Munich, BavariaAges Any age - NCT07859852Recruiting
Blood test for bloodstream infections
This study tests a new blood test that may find bloodstream infections faster and more accurately than standard methods. It could help doctors start the right treatment sooner.
Orange, CaliforniaAges Any age - NCT06263439Recruiting
Watching hand, foot, and mouth disease in children
This study simply watches children with hand, foot, and mouth disease or herpangina to learn more about these illnesses. Your child's regular care won't change, and no extra treatments are given.
Clermont-FerrandAges Up to 10 years - NCT07870525Recruiting
Chest x-ray vs low-dose CT in emergency department
This trial compares two types of chest imaging for adults in the emergency department who might have community-acquired pneumonia (CAP). It helps find out if a low-dose CT scan is better than a regular chest x-ray for diagnosing this condition.
AabenraaAges 18 years+ - NCT07860333Recruiting
Moving after stroke treatment
This trial tests whether starting mobilization earlier after a stroke procedure improves recovery. It may help patients get moving sooner and regain function faster.
TampereAges 18 years+ - NCT07864194Recruiting
Suction vs standard stone removal for kidney stones
This trial compares two ways of removing kidney stones during a procedure called ureterorenoscopy (a tube with a camera is used to reach and remove the stone). The aim is to see if using suction during the procedure helps remove stones more effectively than the standard method.
Çorum, ÇorumAges 18–75 - NCT05977283Recruiting
Follow-up study for people whose hepatitis B test improved
This study follows people with hepatitis B (HBV) blood tests that have improved over the last year. It aims to learn what happens after the hepatitis B surface antigen (HBsAg) goes down, and may help doctors better predict outcomes.
