Kalangala, SseseAges 15 years+ - NCT07534007Recruiting
Shingles vaccine response in patients on immune-modifying drugs
This study tests a new shingles vaccine in people with psoriasis or myelofibrosis, some of whom take immune-modifying medications. Researchers want to understand how well the vaccine works and how the immune system responds in these groups.
Pavia, LombardaAges 18–100 - NCT07066540Recruiting
Trial of Reamberin for Viral Stomach Infections in Children
This trial tests if the drug Reamberin, given through an IV, can help children aged 1 to 6 recover faster from a viral stomach infection. It's for kids who need fluids through a vein and have symptoms like vomiting, fever, and tiredness.

Making medicine use better in Elche
This study works with the community to find ways to use medications like antidepressants, blood pressure drugs, and antibiotics more wisely. It is a collaboration among residents, healthcare workers, and local groups to create solutions together.
Elche, AlicanteAges 18 years+ - NCT07606950RecruitingPhase 3
Testing HRS-5635 to improve hepatitis B treatment
This study tests whether adding a new drug called HRS-5635 to your current hepatitis B medicine works better than your current treatment alone. You may qualify if your hepatitis B is already controlled with antiviral pills and your viral levels are very low.
Guangzhou, GuangzhouAges 18 years+ - NCT07614165Enrolling by invitation
HIV Prevention Decision Tool for Young Adults
This study tests a simple online tool to help young people decide whether PrEP (a daily pill that prevents HIV) might be right for them. The tool uses information from an at-home HIV test and is designed to make PrEP information easier to understand.
Ann Arbor, MichiganAges 18–39 - NCT07696884Recruiting
Vascular graft and endograft infection study
This study looks at how the body responds to infections in artificial blood vessels (vascular grafts or endografts). It may help understand why some people get infections and how to better treat them.
AarhusAges 18 years+ - NCT05911997RecruitingPhase 1
Compare stool treatment options for repeat C. difficile infection
This Phase 1 study tests a stool-based treatment approach for people who keep getting C. difficile diarrhea that returns after antibiotics. The goal is to see whether the treatment is safe and works to stop future episodes.
New York, New YorkAges 18 years+ - NCT07035535Enrolling by invitation
Using genetic tests to predict antibiotic resistance in lung infections
This trial looks at whether a special genetic test (tNGS) can predict which antibiotics will work for bacteria causing lung infections. It may help doctors choose the right treatment faster.
Nanjing, JiangsuAges 18 years+ - NCT05208710RecruitingEarly Phase 1
Study new HPV vaccine in healthy adults
This early study tests a new HPV (human papillomavirus) vaccine to see if it can safely trigger an immune response in healthy adults. It’s for people who have not had an HPV vaccine before and can follow study vaccination and pregnancy-prevention rules.
HeidelbergAges 18–45 - NCT06749054RecruitingPhase 2
Long-acting HIV treatment for teens and children with drug resistance
This trial tests a long-acting injection called lenacapavir for children and teens with HIV who have tried other treatments and still have detectable virus. It may be an option if current medicines aren't working well enough.
Atlanta, GeorgiaAges Up to 17 years - NCT07525674Recruiting
Vacuum Sealing Drainage for Infected Surgical Wounds
This trial tests whether a special vacuum-sealed dressing (called VSD) helps heal surgical wounds that became infected after obstetric or gynecological surgery. The goal is to see if this treatment speeds healing and reduces complications.
MinyaAges 18–70 - NCT05071079Recruiting
Study infects volunteers with a malaria germ to test treatment
This study gives healthy volunteers a controlled infection with a type of malaria (vivax) to see how the infection behaves and how well curative anti-malaria medicine works. It may help researchers better design and test future malaria vaccines and treatments.
