Reducing bloodstream infections from ICU catheters
This study tests a new method to prevent infections from central lines (special IVs placed in large veins) in intensive care units. If you have a central line in place for more than 24 hours, this research may help improve your safety by finding better ways to avoid catheter-related bloodstream infections.
Shanghai, Shanghai MunicipalityAges Any age - NCT06709196RecruitingPhase 4
Targeted antibiotics to prevent infections after bladder removal
This trial tests if using a personalized antibiotic approach before surgery can reduce infections compared to the usual one-size-fits-all antibiotics. It focuses on people having their bladder removed (cystectomy) with a specific type of urinary diversion.

Arbovirus infection study in the Indian Ocean
This study looks at patients with suspected, probable, or confirmed arbovirus infections (like dengue, chikungunya, or Zika) to understand what factors lead to hospitalization and how severe the illness can be. It may include adults, children, and even newborns if they might have been exposed.
Saint-PierreAges Any age - NCT07118384Recruiting
Comparing two antibiotics for drug-resistant infections
This trial tests two different antibiotic combinations (ampicillin/sulbactam and cefoperazone/sulbactam) to see which works better against a type of bacteria (Acinetobacter baumannii) that is resistant to many other drugs. It is for critically ill patients with signs of sepsis.
CairoAges 21 years+ - NCT06711575Recruiting
Personalized antibiotics for spinal infections
This trial is studying how to personalize the dose of anti-infection drugs for people with spinal infections. The goal is to find the best treatment for each patient to improve outcomes and reduce side effects.
JinanAges Any age - NCT05361941Recruiting
Antibiotic graft to help bone regrow in infected knee surgery areas
This trial tests an antibiotic “graft” placed into or near infected bone cavities around a knee replacement (TKA) to help new bone grow. You may be considered if you have an infected knee implant area and can safely take part in follow-up visits and treatment.
Los Angeles, CaliforniaAges 22 years+ - NCT05910268Recruiting
Study of HIV care training for clinic teams
This study looks at how HIV care can be improved by collecting feedback from clinic staff and leaders who participate in a training program. It may help shape better support and education for nurses, doctors, and primary care teams.
New Haven, ConnecticutAges 18 years+ - NCT06967753RecruitingPhase 4
Switching to a two-drug HIV regimen for transgender women
This trial tests if switching to a two-drug combination of dolutegravir and lamivudine is safe and effective for transgender women who already have undetectable HIV levels on a three-drug regimen. It aims to simplify treatment and reduce side effects.
Buenos Aires, Buenos Aires F.D.Ages 18 years+ - NCT06717594Recruiting
Study of antibiotics for resistant infections
This trial looks at how well two antibiotics, ceftazidime-avibactam and fosfomycin, work together to treat infections caused by highly resistant bacteria called CRE. It may help find the best way to use these medicines.
Bologna, BolognaAges 18 years+ - NCT06718517Recruiting
Testing drug levels to improve antibiotic therapy in liver transplant patients
This trial checks if monitoring antibiotic levels in the blood can help doctors give the right dose to liver transplant patients with serious bacterial infections. The goal is to make the treatment work better.
BolognaAges 18 years+ - NCT05635591Enrolling by invitationPhase 1
KSD-101 vaccine trial for EBV-related blood cancers
This early-phase trial studies KSD-101 (a vaccine treatment) for people whose blood cancers are linked to EBV and who have not responded or have relapsed after standard treatment. It may help your immune system better control the cancer, especially when other options have already been tried.
Wuhan, HubeiAges 18–70 - NCT07576959RecruitingPhase 3
Bismuth with dual therapy for H. pylori infection treatment
This trial tests whether adding bismuth (a mineral compound) to standard two-drug therapy helps cure H. pylori, a common stomach bacteria that can cause ulcers and inflammation. The goal is to see if this combination works better than dual therapy alone.
TaipeiAges 20 years+ - NCT07557589Recruiting
Radiofrequency Treatment for Pilonidal Disease Safety and Effectiveness
This study tests a radiofrequency (heat-based) treatment to safely and effectively treat pilonidal sinus disease—a condition where an infected cavity forms near the tailbone. Researchers will check if this non-surgical approach reduces infection, works well, and keeps patients satisfied over 6 months.
DaxAges 18 years+ - NCT06002607Recruiting
Shorter vs longer antibiotics for severe skin infections
This study compares a shorter course (about 7 days) of antibiotics to a longer course (about 14 days) for people who had surgery for a severe skin and muscle infection. The goal is to see if a shorter treatment works just as well.
Orange, CaliforniaAges 18 years+ - NCT07102745Recruiting
