Detecting causes of infectious eye inflammation
This trial looks for germs causing eye inflammation (uveitis) that may be due to an infection. It could help identify the best treatment for your condition.
ShanghaiAges Any age - NCT07514416RecruitingPhase 1
Safety study of LCFA-01 drug in healthy women
This study tests a new drug called LCFA-01 to make sure it's safe and works as expected in healthy women. The drug is being developed to treat bacterial vaginosis, a common vaginal infection.
Brisbane, QueenslandAges 18–40 - NCT06570850RecruitingPhase 4
Colistin alone vs colistin plus fosfomycin for CRAB infections
This study compares colistin by itself versus colistin combined with fosfomycin to see which works better for certain infections caused by CRAB bacteria. The goal is to help patients with pneumonia, urinary tract, skin, or bloodstream infections.
Chiang MaiAges 20 years+ - NCT07390474RecruitingPhase 1
HIV vaccine safety and immune response study for healthy adults
This study tests two experimental mRNA-based HIV vaccines to see if they are safe and create an immune response. It is for healthy adults aged 18 to 55 who do not have HIV.
Atlanta, GeorgiaAges 18–55 - NCT05156151Enrolling by invitation
Lenticule Implant for Herpes-Related Cloudy Cornea
This trial implants a small lens-shaped tissue (called a lenticule) into the cornea to help restore its clarity and improve vision in people with vision problems from repeated herpes infections. If you've had ongoing issues with herpes in your eye, this treatment might reduce scarring and help you see better.
PristinaAges 21–46 - NCT06574399Recruiting
Staph blood infection study: understanding severity
This study looks at different types of Staph aureus blood infections to understand which ones are more likely to cause severe illness or death. It may help doctors predict who needs more aggressive treatment.
