Testing a new oral vaccine to prevent shigella and ETEC infection
This trial tests an oral vaccine designed to protect against two common causes of severe diarrhea: shigella and ETEC bacteria. Healthy adults aged 18 to 50 will receive the vaccine and later be exposed to the bacteria to see if it works.
Baltimore, MarylandAges 18–50 - NCT07047989RecruitingPhase 1
NWRD09 for HPV-16 related cervical high-grade changes
This trial tests a new drug called NWRD09 for women with high-grade cervical cell changes (CIN 2/3) caused by HPV type 16. The goal is to see if the drug can help clear these abnormal cells without needing surgery.

Ruxolitinib cream study for hidradenitis suppurativa
This study tests a cream called ruxolitinib for people with hidradenitis suppurativa (HS). The goal is to see how much of the cream is absorbed when it's applied to a large area of the body.
Phoenix, ArizonaAges 12–75 - NCT07054099RecruitingPhase 3
Testing a chickenpox vaccine for children ages 1 to 12
This study tests a new chickenpox vaccine (MG1111, also called BARYCELA Inj.) in healthy children aged 1 to 12 years. It checks how well the vaccine works and if it is safe, with two doses given over time.
Khon Kaen, Changwat Khon KaenAges 1–12 - NCT05659589Recruiting
Using a kidney toxin level to predict heart effects in AKI
This study looks at whether measuring indoxyl sulfate, a substance that can build up when kidneys are injured, can help predict how blood vessels and the heart are affected during acute kidney injury (AKI). It may help doctors understand who is at higher risk of heart-related problems while AKI is happening.
AmiensAges 18 years+ - NCT07046988Recruiting
Terbinafine study for kids with scalp ringworm
This study looks at how the antifungal drug terbinafine works in children aged 2 to 18 who have tinea capitis (scalp ringworm). It aims to find the right dose to treat the infection effectively.
BeijingAges 2–18 - NCT07045493Enrolling by invitationPhase 2
Combination therapy for soil-transmitted worms in children aged 2-5
This trial tests whether a combination of medicines works better than a single medicine to treat common intestinal worms (like hookworm and roundworm) in young children in Bangladesh. It is for children who are either stunted (shorter than average for their age) or healthy, and who have a confirmed worm infection.
DhakaAges 2–5 - NCT07047053Recruiting
Shingles vaccine study for people with autoimmune diseases
This study looks at how well the shingles vaccine works in people with autoimmune inflammatory diseases. Researchers want to make sure the vaccine provides good protection for patients whose immune systems are affected by their condition or treatment.
ParisAges 18 years+ - NCT07051694Recruiting
Ear nerve stimulation for sepsis patients in the ICU
This trial tests a non-invasive ear stimulation device (taVNS) as an extra treatment for sepsis in the ICU. It may help reduce inflammation and improve recovery.
ChongqingAges 18–80 - NCT07051668Recruiting
Improving Sepsis Diagnosis in Pediatric Emergency Transfers
This study tests a new toolkit to help doctors better diagnose sepsis in children during emergency transfer calls. It looks back at records and call recordings to see if the toolkit improves how sepsis is spotted early.
Aurora, ColoradoAges 1 month+ - NCT07054177Recruiting
Saliva test for gum disease in pregnancy
This study looks at how pregnancy and gum disease might change the chemicals in your saliva. By comparing pregnant women and non-pregnant women, researchers hope to find a simple way to screen for gum problems during pregnancy.
