Antibodies plus early HIV treatment to try for HIV remission
This study tests whether giving special HIV-fighting antibodies along with starting standard HIV medicine soon after infection can help you reach “HIV remission.” It may reduce or delay the return of detectable virus, but you must be willing to follow close monitoring and specific study steps.
Birmingham, AlabamaAges 18–70 - NCT07200817Recruiting
Blood markers to predict outcome in sepsis patients
This study looks at simple blood tests (like levels of certain white blood cells and a protein called procalcitonin) to see if they can predict how well people with sepsis will do in the intensive care unit. It may help doctors understand your infection better.
CairoAges 18–70 - 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 - NCT06668012Recruiting
Vaginal health study for premenopausal women
This study looks at changes in vaginal bacteria in women before menopause. It aims to understand why some women have higher vaginal pH and how it relates to symptoms.
BarcelonaAges 18–45 - NCT05785169Recruiting
Trial improves clinic support for people with HIV
This study works with specific Ryan White clinics to improve support and well-being for both patients and healthcare staff. It will help test whether an “all-facility” approach in participating clinics can create a better care experience.
New York, New YorkAges 18 years+ - NCT06423612Recruiting
HIV monitoring with a urine test to improve viral suppression
This trial tests whether a simple urine test can help people living with HIV who have not yet achieved viral suppression. The test is done right at the clinic to quickly check if their HIV medication is being taken correctly, so their doctor can offer extra support.
East LondonAges 18 years+ - NCT07189364Enrolling by invitation
Comparing antibiotic prescribing to help doctors improve
This trial tests whether giving doctors a report comparing their antibiotic prescribing to their peers can improve how antibiotics are used. If you are a general medicine patient who stayed in the hospital for a short time, this study may help make antibiotic use safer and more effective.
Toronto, OntarioAges 18 years+ - NCT07186634RecruitingPhase 4
Surgery recovery medicine platform trial
This trial tests different medicines to improve recovery after surgery. It includes adults having surgery that lasts at least 2 hours and requires an overnight hospital stay.
Melbourne, VictoriaAges 18 years+ - NCT05922124RecruitingPhase 4
Testing two antibiotics against resistant lung and bloodstream infections
This trial studies whether cefiderocol plus ampicillin-sulbactam works better than colistin (sometimes with meropenem) for serious infections caused by carbapenem-resistant Acinetobacter baumannii (a hard-to-treat germ). It may help by finding a more effective antibiotic plan for people with these severe hospital-acquired infections.
HaifaAges 16 years+ - NCT06545968Recruiting
Social media to help young people with HIV stay in care
This study tests whether a social media program can help young people with HIV in Uganda stay connected to their medical care. If you are between 15 and 24 years old and are new to care or returning after a break, you may be able to join.
MbararaAges 15 years+ - NCT06841731RecruitingPhase 2
Testing a new antibiotic for hospital-acquired pneumonia
This trial tests a new antibiotic called HRS-8427 for adults with bacterial pneumonia that started in the hospital or while on a ventilator. It may be an option if you need IV antibiotics and haven't already received long-term treatment for this infection.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07180563RecruitingPhase 1/Phase 2
Berberine and doxycycline for chronic endometritis
This trial tests if adding berberine (a plant compound) to the antibiotic doxycycline works better than doxycycline alone for treating chronic endometritis, a long-term inflammation of the womb lining that can affect fertility. It may help women who have this condition.
Yiwu, ZhejiangAges 20 years+ - NCT06848686Recruiting
HIV service ambassador program for people who use drugs
This trial trains people who use drugs to talk with friends in their social network about HIV testing and services. It aims to encourage more people to get tested and linked to care.

Understanding vaccine concerns in pregnant women
This study looks at why some pregnant women might be unsure about getting vaccines. It aims to understand their concerns so that doctors and nurses can better support them.
VanAges 18–45 - NCT07145164Enrolling by invitationPhase 2
IL-15 to boost HIV control after pausing daily meds
This study tests whether giving a small protein called IL-15 can help your immune system keep HIV under control after pausing your daily HIV medications. You will stop your meds for a short time under careful monitoring, and the hope is that your body might learn to fight HIV without daily pills.
San Francisco, CaliforniaAges 18–70 - NCT07158814RecruitingPhase 4
Testing the safety of an RSV antibody in infants
This study checks if it is safe to delay the RSV preventive antibody shot by up to two weeks in infants who are getting their routine vaccines. Your baby will get the antibody at a second visit.
Oakland, CaliforniaAges 1 month–7 months - NCT05642013Recruiting
Short interval exchange surgery for infected hip or knee implants
This study compares how to replace an infected hip or knee implant using a two-step surgery with a shorter waiting time. It aims to reduce the time between surgeries while still safely treating the infection.
MontpellierAges 18 years+ - NCT07148960Enrolling by invitationPhase 4
Does early dual therapy improve outcomes for staph bloodstream infections?
This study looks at whether giving two antibiotics early for a serious staph infection in the blood leads to better results than the standard one antibiotic. It uses existing hospital monitoring and follow-up visits to track progress.
Morgantown, West VirginiaAges 18 years+ - NCT06553911Recruiting
