Kaohsiung CityAges 18–100 - NCT05746442Recruiting
Interactive quitting messages for Khmer-speaking people with HIV
This trial tests whether interactive, personalized messages can help people who smoke cigarettes quit. It is designed for Khmer-speaking adults living with HIV and aims to support a quit attempt within about two weeks.
Phnom PenhAges 18 years+ - NCT05775614Enrolling by invitation
Catheter care rinse study to prevent infections and improve comfort
This study tests a catheter “rinse” product (UroTainer) or plain saline to help keep a permanent catheter working and reduce infection risk. It also looks at comfort and quality of life for people who have had catheter problems like blockage or buildup.
OdenseAges 18 years+ - NCT05774548Recruiting
Study of PrEP use and its cost in HIV prevention
This study looks at how taking PrEP (medicine to prevent HIV) affects HIV prevention and how much it costs in real life. You may be able to join if you are HIV-negative and are interested in starting, currently using, or have used PrEP before.
Bangkok, BangkapiAges 18 years+ - NCT05761197Recruiting
Study of mouth yeast infection and a preventive treatment
This trial studies children ages 9–15 months and looks at oropharyngeal yeast infection in the mouth (often called “OPC”). It may help researchers understand how to prevent or manage this condition.
Philadelphia, PennsylvaniaAges 9 months–1.3 years - NCT05762991Recruiting
AI test to help diagnose stomach bacteria and early stomach changes
This trial checks whether an artificial intelligence (computer) system can help diagnose Helicobacter pylori (a common stomach bacteria) and early stomach “premalignant” changes using endoscopy results. It may help doctors spot problems more accurately when you have a scheduled scope.
TaipeiAges 20–80 - NCT05770622RecruitingPhase 4
Vancocin dosing check in young infants with infections
This trial studies a better way to monitor and adjust vancomycin (an antibiotic) dosing in very young infants. It may help your baby get the right dose while reducing the risk of under- or over-dosing.
Melbourne, VictoriaAges birth–3 months - NCT05763069Enrolling by invitation
Home monitoring for high-risk pregnancies
This study tests whether checking certain pregnancy warning signs at home (with monitoring technology) can help manage high-risk pregnancies. It may allow closer follow-up while you stay at home, aiming to improve safety and decision-making.
OsloAges 18–50 - NCT05769816RecruitingPhase 2
Combination treatment aimed to cure chronic hepatitis B
This Phase 2 study tests a combination therapy to help people with chronic hepatitis B reach a “functional cure,” meaning the hepatitis B surface antigen (HBsAg) is lost for a sustained period. If you qualify, you’ll be closely monitored to see how well the treatment works and whether it’s safe for you.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05769023Enrolling by invitation
Pilot test targeting HIV prevention for people who inject drugs
This pilot program studies where HIV risk is highest and uses that information to decide how prevention efforts should be delivered. If you’ve used opioids recently and you inject drugs, you may be invited to participate to help reduce HIV risk.
Baltimore, MarylandAges 18 years+ - NCT05775718RecruitingPhase 2
Shingrix shot after bone marrow transplant to prevent shingles
This Phase 2 study tests whether an additional Shingrix (RZV) vaccine dose helps prevent shingles in people who previously had an allogeneic bone marrow or stem cell transplant. It focuses on people who are at least a year out from their first two Shingrix doses.
Aurora, ColoradoAges 18–79 - NCT05752500Recruiting
Behavior coaching to help older adults with HIV move more
