Testing a blood test to guide antibiotics for lung infections
This trial studies whether using the MeMed BV® blood test in the emergency room or urgent care can help doctors decide when antibiotics are (or are not) needed for suspected lung infections. It may help reduce unnecessary antibiotics while still treating infections when needed.

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 - NCT07043855Enrolling by invitation
Shorter antibiotics after Whipple surgery

Testing antibiotic delivery method for hip replacement surgery
This study compares a new way of delivering antibiotics directly into the bone during hip replacement surgery versus the standard IV method. The goal is to see if this approach prevents infection just as well while potentially improving outcomes.
Somerset, New JerseyAges 18 years+ - NCT07235683RecruitingPhase 4
Stronger CMV treatment for lung transplant recipients
This trial tests adding a drug called letermovir to standard antiviral therapy for lung transplant patients with CMV infection. The goal is to see if the combination helps clear the virus faster and more effectively.
Toronto, OntarioAges 18 years+ - NCT07234331Recruiting
Studying antibiotic resistance in nursing home residents
This trial looks at antibiotic resistance by testing wastewater in nursing homes. It aims to understand how resistance spreads and how to better protect residents.
AngersAges 18 years+ - NCT07232355Recruiting
Cervical cancer prevention with at-home self-sampling
This trial tests a new way to screen for cervical cancer using a self-collected sample at home. It aims to find high-risk HPV types early to prevent cancer.
Sunnyvale, CaliforniaAges 30–64 - NCT07232095RecruitingPhase 4
7-Day treatment for H. pylori with new acid blocker and antibiotics
This trial tests a 7-day combination of vonoprazan, high-dose amoxicillin, and bismuth to treat Helicobacter pylori infection in people who have never been treated for it before. The goal is to see if this short course is effective and safe for curing the infection.
Nanjing, JiangsuAges 18–70 - NCT07231640Recruiting
Improving PrEP care for clinic staff
