Antibiotics to prevent infections in hemodialysis catheters
This trial tests whether taking preventive antibiotics (or a placebo sugar pill) can lower the risk of infections in people who receive hemodialysis through a catheter. It may help protect you from serious catheter-related infections, but you must be able to follow the study’s medicine and consent rules.

New York, New YorkAges 18 years+ - NCT05247112Recruiting
Tracking antibiotic resistance in H. pylori infections in Korea
This study looks at how resistant H. pylori (a stomach germ) is to different antibiotics in Korea. It uses stomach endoscopy samples to test which antibiotics may or may not work, helping guide future treatment choices.
Seongnam-si, Gyeonggi-doAges Any age - NCT05332444RecruitingPhase 4
Check if stomach-bacteria testing improves rescue treatment for H. pylori
This study compares two ways to treat Helicobacter pylori (H. pylori) infection that didn’t go away with prior therapy. One approach uses test results to guide which medicines to use, and the other uses standard (“empiric”) treatment. The goal is to see which works better and more safely as a rescue plan.
TaipeiAges 20 years+ - NCT04702022Recruiting
Extra PET scan to check for silent kidney transplant rejection
This study tests whether an additional PET scan can help detect and guide treatment for “subclinical” (silent) rejection in people with kidney transplants. It may help doctors spot problems earlier and manage them more appropriately.

Surgery for a one-eye surface tumor in people with HIV
This study looks at whether removing a suspected pre-cancer/cancer growth on the surface of the eye can be done safely in people living with HIV. It is a feasibility (safety and practical) study, helping doctors refine the best surgical approach and follow-up.
KampalaAges 18 years+ - NCT05319353RecruitingPhase 3
Maribavir for kids with CMV after transplant
This Phase 3 trial tests maribavir (an anti-CMV medicine) in children and teens who get CMV infection after a stem cell or solid organ transplant. It aims to see whether the drug is safe and well-tolerated, and whether it can reduce the virus in the body.
Wilmington, DelawareAges Up to 17 years - NCT04663152Recruiting
Study support to help you stay on treatment
This study tests integrated support that includes counseling, help with following your treatment plan, and research activities to improve treatment adherence. You may be a good match if you live in Miami-Dade and meet the viral load requirement.

Antibiotic plans and outcomes after two-stage joint revision
This study looks at how antibiotic treatment (especially the course length and approach) relates to infection control and results after a two-step surgery for joint infections. If you’ve had a spacer placed, finished at least 6 weeks of antibiotics, and then had the second surgery, the research team may want to follow your outcomes over time.

Help increase HPV vaccine completion in Denver families
This study tests an educational program to help people in Denver who have not yet started the HPV vaccine (or haven’t finished it) complete the vaccine series. It may help families understand the vaccine and follow through with completing the recommended doses.
Denver, ColoradoAges 18 years+ - NCT04678154RecruitingPhase 3

ParisAges 18 years+ - NCT05377463Recruiting
Behavior coaching to help keep HIV virus levels controlled
This study tests a counseling program (bio-behavioral intervention) designed to help people with HIV keep their virus levels under control over time. It may be especially relevant if your current HIV treatment has been hard to stick with or you haven’t had recent viral load checks.
Ciudad Juárez, ChihuahuaAges 18 years+ - NCT04858217Recruiting
Testing blood and joint fluid tests for hip or knee infection
