- NCT05117398RecruitingPhase 3
Dalbavancin vs standard antibiotics for catheter bloodstream infection
This trial tests whether dalbavancin (an antibiotic given as a dose or doses) works as well as standard antibiotics to treat bloodstream infections related to a removed IV catheter caused by Staphylococcus aureus. It may help reduce treatment time and dosing complexity if you qualify.
GarchesAges 18 years+ - NCT05123755RecruitingPhase 2
Testing a new medicine in hospitalized pneumonia patients needing oxygen
This Phase 2 trial tests an investigational medicine (given in increasing doses) for hospitalized people with pneumonia who need supplemental oxygen. It aims to see if the medicine is safe and potentially helps the pneumonia process in the early hospital period.
Newport Beach, CaliforniaAges 18 years+ - NCT05124977Recruiting
Antibiotic plan study for ventilator pneumonia in ICU
This trial tests an “antibiotic stewardship” approach—choosing and adjusting antibiotics in a smarter way—for a first episode of pneumonia in patients on a breathing machine. It may help ensure the right antibiotics are used at the right time, while avoiding unnecessary or overly broad treatment.
Clichy-sous-BoisAges 18 years+ - NCT05127252Recruiting
Study how gut bacteria may affect time to pregnancy
This study looks at whether differences in the gut (microbiome) are linked to how long it takes to get pregnant and pregnancy outcomes. It may help researchers understand who might benefit from future microbiome-focused approaches.
Stockholm, HuddingeAges 18–40 - NCT05127980Recruiting
Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues. You might be offered a chance to help doctors understand why some people get longer or more intense symptoms from infectious mononucleosis.
BaselAges 18 years+ - NCT05137119RecruitingPhase 4
Adaptive study of treatments for staph bloodstream infection
This trial tests the best treatment approach for bloodstream infections caused by Staphylococcus aureus (“S. aureus”). It uses a flexible design to decide which treatment track you fit into, and may help improve recovery while avoiding unnecessary medications.
Houston, TexasAges Any age - NCT05141058RecruitingPhase 1
T cell therapy to help prevent COVID-19 after transplant
This Phase 1 trial tests a donated immune-cell treatment (T cells) to help immunocompromised people fight or resist COVID-19 after they recently received a bone marrow or stem cell transplant. It aims to see if the treatment is safe and if it helps the body respond better to the virus.
Washington D.C., District of ColumbiaAges 2–80 - NCT05146336Recruiting
CytoSorb registry for critically ill patients needing blood treatment
This registry collects information about critically ill patients who receive the CytoSorb 300 mL blood treatment. It may help doctors better understand when the treatment works best and when it should not be used.
KlagenfurtAges Any age - NCT05147519Recruiting
Observes HIV and other infections to learn who gets them
This is an observational study that follows people to better understand how HIV and other infections (like sexually transmitted infections) happen and change over time. It may help researchers improve prevention and care, but it is mainly for monitoring rather than testing a new treatment.
Kericho, Kericho CountyAges 14–55 - NCT05153694Recruiting
Study of infections after bladder removal
This observational study follows people after surgery to remove the bladder to learn how often infections happen and what they look like. It may help doctors better prevent and manage complications after this operation.
Munich, Outside U.S./CanadaAges Any age - NCT05153824Recruiting
Study of normal E. coli in the gut microbiome
This study looks at how a common gut bacterium (E. coli) naturally changes over time in healthy adults. It may help scientists understand how healthy gut bacteria behave and evolve.
ParisAges 18–65 - NCT05157685RecruitingPhase 3
Azithromycin for chronic pus-filled sinus inflammation
This Phase 3 trial tests whether the antibiotic azithromycin can improve chronic sinus problems where there is persistent pus and swelling. It’s for adults who have not improved despite at least two prior antibiotics.
BordeauxAges 18–70 - NCT05159466Recruiting
Transplant from HIV-positive donors to HIV-positive recipients
This trial studies whether it’s safe and effective for HIV-positive people to receive organ transplants from HIV-positive donors. It focuses on matching HIV treatment before and after transplant and checking for major complications.
Metairie, LouisianaAges 18 years+ - NCT05164744Recruiting
MRI study of heart tissue changes after COVID-19
This study uses a heart MRI to look for leftover (healing) changes in heart tissue after COVID-19. It may help researchers better understand what ongoing heart effects can happen after infection.
Brooklyn, New YorkAges 18 years+ - NCT05166850Recruiting
Preventive cholera help for households for 7 days
This study tests a 7-day preventive intervention for cholera-like diarrhea in households without running water. It may help reduce illness spread and protect young children when families lack safe water at home.
Bukavu, South KivuAges Any age - NCT05172089Recruiting
Treating recurring infection in diabetic foot ulcers
This trial studies an approach to treat bacteria living in a diabetic foot ulcer and help prevent the ulcer from coming back. You may be able to join if you have an open diabetic foot ulcer and good blood flow to the wound.
Tucson, ArizonaAges 18 years+ - NCT05179499RecruitingPhase 3
Early norepinephrine for low blood pressure in sepsis
This Phase 3 trial tests whether starting a medicine called norepinephrine early can improve outcomes for adults with sepsis (a serious body-wide response to infection) and low blood pressure. You might be considered if you’re very early in hospital care and meet specific blood pressure and lactate tests.
AintreeAges 18 years+ - NCT05181696Recruiting
Study of chest X-ray severity scores in ICU COVID-19 pneumonia
This study reviews past chest X-rays from people who were hospitalized in the ICU for COVID-19 pneumonia caused by SARS-CoV-2. It aims to see how well a chest X-ray severity scoring system reflects how sick the lungs were.
OsijekAges 18–90 - NCT05182463RecruitingPhase 4
Peginterferon test for inactive chronic hepatitis B
This trial studies whether pegylated interferon can help people with inactive chronic hepatitis B stay stable or improve outcomes. You may qualify if your virus levels and liver blood tests are currently low and you’ve never used antiviral treatments.
Guangzhou, GuangdongAges 18–60 - NCT05183490RecruitingPhase 1
Cell therapy for repeated viral infections after transplant
This early-phase (Phase 1) study tests an immune cell treatment (R-MVST) to help people whose immune system has been weakened by a past transplant and who keep getting viral infections reactivated or not responding well to standard treatment. It may help your body control viruses like EBV, CMV, adenovirus, or BK virus.
New York, New YorkAges 18 years+ - NCT05188612Recruiting
Hospital patients with confirmed COVID-19 survey study
This study collects information from adults who are in the hospital for confirmed COVID-19. The goal is to better understand what happens during acute (early) COVID-19 and improve care.
Bologna, BolognaAges 18 years+ - NCT05190978Recruiting
Test mesh use for breast reconstruction above the muscle
This study tests whether using surgical mesh can be done safely and works well in breast reconstruction done right away, in front of the chest muscle (pre-pectoral) using tissue expanders. It may help improve how the reconstructed area holds up, but you’d need to meet specific surgical and health requirements.
Los Angeles, CaliforniaAges 22–75 - NCT05190718Recruiting
Pharyngeal electrical stimulation for swallowing trouble after brain injury
This trial tests a non-drug therapy that uses gentle electrical stimulation to help people swallow safely when swallowing is affected by certain brain or nerve conditions. If you qualify, you may receive this approach to improve swallowing and reduce choking risk.
Tulln, Low AustriaAges 18 years+ - NCT05191381Recruiting
Immune treatment using exosome therapy for severe COVID-19
This trial tests whether immune-supporting treatment made from exosomes can help people with critically severe COVID-19 and lung damage. If you qualify, you may receive this therapy as part of the study to see if it improves outcomes.
