Infection activity in travelers and migrants with chronic schistosomiasis
This trial looks at how active a long-term schistosomiasis infection is in travelers and migrants. It aims to better understand the infection to help guide treatment.
AntwerpAges 5 years+ - NCT07198139RecruitingPhase 1/Phase 2
Testing a new norovirus treatment in healthy adults
This trial tests an investigational medicine called CDI-988 to see if it can prevent or treat norovirus infection. Healthy adults will be intentionally exposed to a mild norovirus strain to see how the medicine works.
Decatur, GeorgiaAges 18–49 - NCT07200193RecruitingPhase 1/Phase 2
Study of CRMA-1001 for chronic hepatitis B
This trial tests a new drug called CRMA-1001 in people with chronic hepatitis B who are already on antiviral therapy. The goal is to see if it can help control the virus better.

GrazAges 18–99 - NCT07202949RecruitingPhase 2
Extended antibiotics with methenamine for chronic urinary tract infection
This trial compares a longer, higher-dose antibiotic course combined with methenamine hippurate (a urinary antiseptic) against standard care (low-dose antibiotics or methenamine alone) for women with chronic urinary tract infections. It aims to see if the extended treatment is more effective at relieving persistent symptoms.
