Swiss database for tracking hard-to-treat infections
This study builds a Swiss database using lab genetic testing (whole genome sequencing) plus basic patient information to track outbreaks of serious, drug-resistant, and sometimes high-infectious pathogens. Your data could help researchers understand how these germs spread and how to better prevent them.

Skin prep study to reduce bacteria in shoulder replacement surgery
This study tests whether a specific skin-cleaning method before shoulder replacement surgery can reduce a common bacteria (Cutibacterium acnes) found on skin and deeper samples. It may help lower the risk of infection or contamination during prosthetic shoulder surgery.
AngersAges 18 years+ - NCT04496024Recruiting
How ofloxacin levels may affect older adults with bone infections
This study looks at whether blood levels of the antibiotic ofloxacin in people over 65 are linked to side effects, in older adults hospitalized for bone and joint infections. It may help doctors choose safer doses, especially when switching from IV treatment to pills.
AmiensAges 65 years+ - NCT04444440RecruitingPhase 4
Antibiotic prevention after bladder Botox for overactive bladder
This trial studies whether taking an antibiotic around the time of bladder Botox can lower the risk of urinary infections. It’s for women with overactive bladder who tried standard medicines but didn’t get enough relief.
Edmonton, AlbertaAges 18 years+ - NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT04188743RecruitingPhase 2/Phase 3
Stool transplant to clear antibiotic-resistant gut germs
This trial tests whether a stool (fecal) transplant from a screened donor can help remove antibiotic-resistant gut bacteria (MDRO) that keep coming back in your stool tests. It aims to reduce colonization that makes follow-up and treatment harder.
Ghent, Oost-VlaanderenAges 18 years+ - NCT04358289Recruiting
Trial to reduce unnecessary antibiotic use in community clinics
This study works with local communities and commune health clinics to lower unnecessary antibiotic prescribing for respiratory infections. It uses routine clinic records and community input to test what changes help patients safely get antibiotics only when needed.
Nam ĐịnhAges Any age - NCT04351347RecruitingPhase 2/Phase 3
Testing higher-dose ivermectin for COVID-19
This trial studies whether a higher dose of ivermectin helps people with COVID-19. It looks at how well the treatment works and whether it causes side effects for participants.
TantaAges Any age - NCT04527055Enrolling by invitationPhase 4
Bismuth treatment for H. pylori: 10 or 14 days
This trial compares two common stomach medicine plans that use bismuth for 10 days versus 14 days to clear an H. pylori infection. It may help you find a shorter or more effective treatment schedule if you have H. pylori confirmed by an endoscopy.
TainanAges 18–100 - NCT04161768RecruitingPhase 3
Antibiotic pill study to prevent repeat belly infection in liver disease
This study tests whether taking norfloxacin plus itopride helps prevent another episode of spontaneous bacterial peritonitis (a serious belly infection) in people with cirrhosis and fluid buildup in the abdomen. It compares that combo to norfloxacin alone to see which approach better lowers repeat infections.
TantaAges Any age - NCT04526431Recruiting
Tacrolimus dose study in early kidney transplant patients
This study looks at how tacrolimus (a rejection-preventing medicine) should be dosed in the first days to years after a kidney transplant. It may help personalize dosing by comparing different patient groups, including using genetic testing.
Grenoble, Auvergne-Rhône-AlpesAges 18 years+ - NCT04535661Recruiting
Study of who develops carbapenem-resistant infections in PICU children
This study looks at factors that make some hospitalized children in the pediatric intensive care unit (PICU) develop or carry germs called carbapenem-resistant Enterobacteriaceae. It aims to understand who is at higher risk and why, which may help prevent infections in the future.
Shanghai, Shanghai MunicipalityAges 4 weeks–18 years - NCT04168099RecruitingPhase 3
Oral gemifloxacin versus IV cefotaxime for peritonitis
This trial compares two antibiotic treatments for spontaneous bacterial peritonitis—one taken by mouth (gemifloxacin) versus one given through a vein (cefotaxime). It may help find the best way to treat this infection and improve recovery.
TantaAges 18 years+ - NCT02996656Recruiting
Antibiotic prevention for skin bacteria in shoulder surgery
This study checks whether giving an antibiotic “ahead of surgery” can reduce problems from common skin bacteria (Propionibacterium acnes) during primary shoulder surgery. It may help lower the risk of infection around the new joint/repair.
Montreal, QuebecAges 18 years+ - NCT06821100RecruitingPhase 1
Thymalfasin to Boost COVID-19 Vaccine Response in Older Adults
This trial tests whether a drug called thymalfasin (thymosin alpha 1) can help older adults (65+) get a stronger immune response from their COVID-19 booster shot. It may be especially helpful for those whose immune systems have weakened with age.
Houston, TexasAges 65–100 - NCT03546829RecruitingPhase 1
Testing targeted radiation plus short anti-microbial treatment
This early safety study tests a combination of focused radiation and a targeted anti-microbial (antibiotic/antifungal/antiviral/anti-parasite) plan for certain lung cancer that is starting to progress in a few spots. It aims to see whether this approach is safe and helps control the small areas of progressing cancer after prior treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02822768Recruiting
Packing versus no packing for skin abscesses
This trial compares two common ways of treating a skin abscess after it’s drained: placing a packing material in the wound or leaving it un-packed. The study aims to see which approach leads to better healing and fewer problems after 48 hours.
Fresno, CaliforniaAges 18 years+ - NCT03474822RecruitingPhase 1/Phase 2
Plasmodium immune treatment for breast and liver cancers
This early-phase study tests an immune-based treatment (using Plasmodium) for people with advanced breast cancer or advanced liver cancer. It aims to see whether the treatment is safe and whether it can help the body’s immune system fight the cancer.
Guangzhou, GuangdongAges 18–70 - NCT03636464Recruiting
Antibiotic testing in people on kidney dialysis
This trial studies how common antibiotics move through the body when someone is on kidney replacement therapy (dialysis), including when dialysis starts during treatment. The results may help doctors choose the right antibiotic dose and timing for better infection treatment.
