Study sedative effects on ongoing brain inflammation after severe COVID
This study looks at whether a specific ICU sedative (dexmedetomidine) affects long-term inflammation in the brain after severe COVID with ARDS and deep sedation. It uses PET and MRI scans and special tracers to understand persistent inflammation and why it may last.
ParisAges 18–74 - NCT06746701Recruiting
Peginterferon with NA to prevent liver cancer in hepatitis B
This study tests whether combining peginterferon alpha-2b with a nucleoside analog can lower liver cancer risk in people with chronic hepatitis B who have a family history of liver cancer. It compares the combination therapy to nucleoside analog alone.
Guangzhou, GuangdongAges 18–65 - NCT03691883Recruiting
Using an algorithm to stage tuberculosis
This trial helps doctors organize and “stage” tuberculosis (TB) using a structured approach. It may improve how care decisions are made by using confirmed TB information and donated samples/data.
Badalona, BarcelonaAges Any age - NCT05300035RecruitingPhase 2
HIV treatment add-on antibodies during early infection
This study tests whether adding two antibody medicines to standard HIV treatment helps people control HIV better after stopping treatment. It focuses on people with recently diagnosed (“primary”) HIV infection, aiming to improve long-term control after ART is interrupted.
BobignyAges 18–70 - NCT06020716RecruitingPhase 4
Antibiotics for chronic wet cough in toddlers
This study tests whether the antibiotic Augmentin helps children aged 9 months to 3 years with long-lasting wet cough (more than 4 weeks). It aims to find better ways to treat and understand this common problem in toddlers.
ÅlesundAges 9 months–3 years - NCT06254313Recruiting
Studying neutrophils in flu-related lung injury
This trial looks at how a type of white blood cell affects lung inflammation in people with severe influenza. It may help researchers find better treatments for respiratory failure caused by the flu or other infections.
BordeauxAges 18 years+ - NCT07536308RecruitingPhase 1
Nasal COVID-19 booster vaccine safety trial
This trial tests a new nasal spray COVID-19 booster vaccine. It aims to see if the vaccine is safe and produces a strong immune response when given through the nose and inhaled, in people who have already been vaccinated.
Decatur, GeorgiaAges 18–64 - NCT06670963RecruitingPhase 4
Epoetin alfa and iron for anemia in sepsis
This trial tests whether a combination of epoetin alfa (a medicine that boosts red blood cell production) and iron derisomaltose (an iron supplement) can safely treat anemia in people with sepsis or septic shock. It may help improve your energy and recovery.
KatowiceAges 18 years+ - NCT06693362RecruitingPhase 1
Stem cell therapy for severe viral pneumonia
This trial tests whether injecting stem cells from the womb's blood supply can help treat severe viral pneumonia. It aims to improve recovery for people who are very sick and need hospital care.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT07534865Recruiting
Heat and Hydrogen Peroxide Patch for Common Warts
This study tests a new patch that combines gentle heat with hydrogen peroxide to treat common warts on hands, feet, or fingers. The patch is applied directly to the wart and may help your body clear the infection.
