Beijing, Beijing MunicipalityAges 14 years+ - NCT07211997Recruiting
FebriDx test for fever and cold symptoms in children
This study tests a finger-prick blood test (FebriDx) to see if it can quickly tell whether a child's fever and cold symptoms are caused by a bacterial or viral infection. If it works, it could help doctors decide whether antibiotics are needed.
Colton, CaliforniaAges 2–11 - NCT07207291RecruitingPhase 1
Study of JKN2501 in healthy volunteers
This trial tests a new drug called JKN2501 in healthy people to find the best and safest dose. It is the first time this drug is being given to humans.
Changsha, HunanAges 18–45 - NCT06286657Recruiting
Xanthohumol and viral infections study
This study tests whether a natural compound called xanthohumol (found in hops) can help your body fight off common viruses. Healthy adults with a normal BMI are invited to participate.
ViennaAges 18–70 - NCT06731374RecruitingPhase 4
New pneumonia vaccine study for healthy adults 18–50
This study tests a new pneumococcal vaccine (PCV15) to see how well it protects against carrying the bacteria that can cause pneumonia. Healthy adults aged 18–50 who have not had a pneumococcal vaccine in the last 5 years may join.
Liverpool, North WestAges 18–50 - NCT06928259Recruiting
A study of hepatitis C treatments and other medications
This trial looks at how two hepatitis C treatments (GLE/PIB or SOF/VEL) interact with other drugs or recreational substances. It may help doctors understand how to better manage treatment for people taking multiple medications.
CadizAges Any age - NCT06927622Recruiting
COVID-19 study for pregnant women and infants
This study follows pregnant women and their babies to learn more about COVID-19 and how it affects them. By taking part, you help researchers understand the virus and improve care for mothers and children.
Jinan, ShandongAges 18 years+ - NCT06928649Recruiting
Studying cell damage in critically ill ICU patients
This trial looks at specific cell damage processes (called ferroptosis and pyroptosis) in very sick ICU patients. The goal is to learn more about these processes so doctors can better treat life-threatening organ failure caused by conditions like sepsis, trauma, or severe bleeding.
EdegemAges 18 years+ - NCT07206745Recruiting
Chinese and Western medicine for severe pneumonia from drug-resistant bacteria
This trial tests a combination of traditional Chinese and Western medicine for adults with severe pneumonia caused by bacteria that are resistant to multiple antibiotics. It aims to see if this combined approach can improve treatment outcomes.
Zhengzhou, HenanAges 18–80 - NCT07209917Recruiting
Cervical cancer prevention for women with HIV and HPV
This trial tests a new way to prevent cervical cancer in women with both HIV and HPV. It focuses on women in India who are already on stable HIV treatment and have a normal cervical exam.
Bangalore, KarnatakaAges 25–50 - NCT07209189RecruitingPhase 2
Chemo and immunotherapy before surgery for head and neck cancer
This trial tests a combination of chemotherapy and an immunotherapy drug called Toripalimab before surgery for certain head and neck cancers. The goal is to see if this approach can reduce the extent of treatment needed while still being effective.
Baltimore, MarylandAges 18 years+ - NCT07211620Recruiting
Using procalcitonin blood tests to guide antibiotic decisions in the ICU
This study compares two ways of using a blood test called procalcitonin to decide when to start antibiotics in critically ill patients with a new infection. The goal is to reduce unnecessary antibiotic use while still effectively treating infections.
BudapestAges 18 years+ - NCT07203638Enrolling by invitation
Antibiotics to prevent pneumonia in ventilated patients
This trial tests whether giving preventive antibiotics to adults on breathing machines lowers the risk of developing pneumonia during ventilation. It is a double-blind study, meaning neither you nor your doctor will know if you receive the antibiotic or a placebo.
Banhā, Al-QalyubiaAges 18–70 - NCT07204756Recruiting

Vasorin test for shock diagnosis and outlook
This study looks at a protein called vasorin in the blood to see if it can help diagnose and predict outcomes in people with severe shock in the ICU. It compares patients with septic shock (caused by infection) to those with shock from other causes.
AmiensAges 18 years+ - NCT07204457RecruitingPhase 2/Phase 3
Meningococcal vaccine trial for healthy adults 19 to 55 years old

Study of two antibiotics during pregnancy
