Xuzhou, JiangsuAges 1 day–18 years - NCT03859050Recruiting
Study immune-cell changes after a controlled endotoxin exposure
This study tests how your lungs’ immune cells respond after a controlled exposure to endotoxin. It may help researchers understand and prevent harmful lung inflammation, even though it is a short, research-focused intervention.
Denver, ColoradoAges 18–50 - NCT03883269RecruitingPhase 4
Tests topical antibiotics’ anti-inflammatory effect in acne
This trial studies whether putting antibiotic creams on mild-to-moderate facial acne reduces inflammation. It may help answer whether topical erythromycin or clindamycin can improve acne-related redness and swelling.
LeidenAges 18–45 - NCT03899428RecruitingPhase 2
Immune therapy versus targeted therapy for advanced liver cancer
This trial compares an immune “checkpoint” medicine to a targeted cancer medicine in people with advanced liver cancer who have hepatitis B in the blood. It aims to lower hepatitis B surface antigen (HBsAg) levels and see which approach works better and is safest.
Hong Kong, Hong Kong SARAges 18 years+ - NCT03996824Recruiting
Gene therapy study for certain vestibular schwannoma surgeries
This trial tests delivering gene therapy into the inner-ear hearing balance nerve cells during surgery for vestibular schwannoma. It may help by improving how the inner ear functions after tumor removal, but you must meet several specific surgery and safety requirements.
Le Kremlin-Bicêtre, Île-de-France RegionAges 18 years+ - NCT05989893Recruiting
Mapping human thinking during brain surgery
This study maps how thinking works in people with epilepsy or brain lesions near important brain areas. It involves testing during brain surgery procedures to help researchers understand healthy brain function.
Houston, TexasAges 18–75 - NCT04016649Recruiting
Study measures how leg veins move and respond
This study measures the properties of human saphenous and popliteal veins. If you’re having certain lower-leg procedures, your care team may collect information to better understand vein function and support future treatment.
Limerick, LimerickAges 18 years+ - NCT04038840RecruitingPhase 1
Brain PET-MR imaging to study schizophrenia connections
This early (Phase 1) study uses a special brain scan to look at synapses—the contact points between brain cells—in people with schizophrenia-related conditions. It helps researchers understand brain activity and connection patterns, which may guide future tests or treatments.
Palo Alto, CaliforniaAges 18–65 - NCT04048993Recruiting
Uses exercise testing to study health in a biobank
This study builds a biobank (a library of health samples and data) using people who can do difficult exercise. It aims to understand how the body works by collecting physical measurements, which may help future research and treatments.
