Early antibiotic treatment guided by a blood test to prevent severe infection
This study tests whether giving an early antibiotic (meropenem) based on a new blood test (PSP) can prevent serious infections (sepsis) in people who come to the emergency department with signs of infection. The goal is to find out if this approach helps them get better faster and avoid more severe illness.
Athens, AtticaAges 18 years+ - NCT06492187Recruiting
Survey to see if you qualify for infectious disease studies
This trial is a quick survey to see if you might be eligible for future infectious disease studies. It helps researchers understand your health background and find the right study for you.

Testing right heart strain to predict fluid response in septic shock
This study tests whether measuring the strain (stretch) of the right upper heart chamber with ultrasound can predict if a patient with septic shock will benefit from more fluids. Septic shock is a severe infection that causes very low blood pressure and organ damage.
AmiensAges 18 years+ - NCT04805164Recruiting
Gentamicin bone paste to treat stubborn long-bone bone infection
This study tests a bone filler/paste called Cerament-G that releases the antibiotic gentamicin directly at the infected bone site. It aims to improve treatment of chronic bone infection (chronic osteomyelitis) in long bones after surgery.

Fecal transplant for preventing colon polyp return
This study tests whether taking capsules of healthy bacteria (fecal microbiota transplant) can help prevent colon polyps from coming back after they have been removed. It might be an option for people who have had an adenoma polyp removed and want to reduce the chance of recurrence.
Guangzhou, GuangdongAges 18–75 - NCT07805707RecruitingPhase 3
Flu vaccine study for adults 65 and older
This study tests a new flu vaccine in adults aged 65 and older to see how well it prevents the flu. If you are generally healthy or manage chronic conditions well, you may be able to join.
Anniston, AlabamaAges 65 years+ - NCT05784038Recruiting
Study of monkeypox infection in Brazil
This is an observational study that follows people with confirmed monkeypox (mpox) to better understand the illness over time. It may help doctors learn what to expect and improve care, but it does not test a new treatment.
Belém, ParáAges 18 years+ - NCT07802639Recruiting
Botulinum toxin injections for uneven lower lip in children
This study tests a weekly injection of botulinum toxin type A (a muscle-relaxing medication, like Botox) to see if it can improve the appearance and movement of an uneven lower lip in children with craniofacial microsomia. If successful, this treatment might reduce the visible asymmetry when smiling or baring teeth.
BeijingAges 5–18 - NCT07807410Recruiting
Special dialysis filter for septic shock with kidney failure
This study tests whether using a special filter (oXiris) during dialysis can better remove harmful toxins from the blood in people with septic shock and kidney failure, potentially helping them recover faster.
Guangzhou, GuangdongAges 18 years+ - NCT07805590Recruiting
How respiratory viruses interact in hospitalized patients
This study looks at how different respiratory viruses interact in hospitalized patients during the winter seasons. It does not involve any new treatment or extra tests – it just reviews existing test results to learn more about these viruses.

Registry for severe, uncontrolled chronic sinusitis in Italy
This trial is a registry that enrolls people with severe, hard-to-control chronic sinusitis. It helps doctors better understand this specific type of inflammation and how it affects symptoms and quality of life.
Rozzano, MIlanAges 18 years+ - NCT06005298Recruiting
Testing SBIRT to help with PrEP and alcohol use
This study looks at whether talking about alcohol use can help people stick with their PrEP routine. It tests a simple program called SBIRT (Screening, Brief Intervention, and Referral to Treatment) to support your health and HIV prevention.
Louisville, KentuckyAges 18–85 - NCT06511583Recruiting
Bronchoscopy for aspiration pneumonia in the ER
This trial tests if using a thin, flexible scope (bronchoscopy) to suck out fluid and debris from the lungs helps adults with aspiration pneumonia in the emergency room. It is for those who need help clearing their airways due to swallowing problems or pneumonia on imaging.
Florence, Tuscany/ItalyAges 18 years+ - NCT06514560Recruiting
Optimizing miltefosine treatment for leishmaniasis patients
This trial tests how well miltefosine works for people with leishmaniasis, a skin infection from a parasite. It aims to find the best way to use this medicine to help patients get better.
Addis AbabaAges 2 years+ - NCT07794748RecruitingPhase 3
Pneumococcal vaccine study for adults aged 18 to 49
This study tests a new pneumococcal vaccine to see if it is safe and triggers a good immune response. It may help protect you from infections like pneumonia, but you must not have had any pneumococcal vaccine since age 5.
Birmingham, AlabamaAges 18–49 - NCT07798648RecruitingPhase 3
COVID-19 vaccine study for children and adults
This study tests a COVID-19 vaccine in children and adults. It may help protect against COVID-19.
Homestead, FloridaAges 5 years+ - NCT06521944Recruiting
RSV vaccine safety registry for pregnant people
This registry follows pregnant people who received an RSV vaccine during a specific window (32 to 36 weeks) to monitor safety. If you got the shot in that time, your information helps researchers understand how well the vaccine works in pregnancy.
Wilmington, North CarolinaAges 18–50 - NCT06519032Recruiting
