Tranexamic acid trial for adults with sepsis in ICU
This trial studies whether early tranexamic acid (a medicine that can reduce bleeding) can change the body’s inflammatory response in people with sepsis. If it works, it may help improve outcomes for certain ICU patients—but you must meet specific safety and eligibility checks.

Hemoperfusion with Polymyxin B for septic shock after heart surgery
This trial studies a blood-filter treatment (hemoperfusion with Polymyxin B) to reduce harmful substances in the blood for people who develop septic shock after heart surgery. It may help by lowering inflammation and improving safety, but it also requires meeting specific signs of severe infection and blood/bleeding conditions.
MoscowAges 18–80 - NCT04921943RecruitingPhase 4
Hypertonic saline to treat MAC lung infection
This trial tests whether inhaled hypertonic saline can improve symptoms and lung health in people with a specific lung infection called MAC. It targets adults with confirmed MAC infection and bronchiectasis who are not already on certain MAC medications.
New York, New YorkAges 18 years+ - NCT04923828Recruiting
Study drug resistance in very sick children with infections
This trial enrolls children in the pediatric intensive care unit (PICU) who have a severe infection. It aims to better understand germs and drug resistance so future treatments can be more effective.
Shanghai, Shanghai MunicipalityAges 1 month–16 years - NCT04923958Recruiting
Testing new TB screening and diagnostic tests
This study tests rapid TB screening and lab-style diagnostic methods to see how well they find TB disease and TB that is resistant to rifampin (a key TB drug). It may help doctors diagnose TB faster and more accurately, especially in people at higher risk.
TbilisiAges 12 years+ - NCT04931225RecruitingPhase 3
Landiolol for heart-rate and circulation problems in septic shock
This Phase 3 trial tests whether landiolol (a short-acting heart-rate–lowering medicine) can improve blood circulation in adults with septic shock whose heart rate is too fast. Doctors will also check that the medication is safe in this critical-care setting.
ParisAges 18 years+ - NCT05735717RecruitingPhase 2
T-cell transplant using depleted receptors for blood cancers
This Phase 2 study tests a specialized stem cell transplant that removes certain immune “T-cell” receptors to help treat blood cancers like acute leukemia. It may help your body rebuild a healthier immune system after high-dose treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT07224490RecruitingPhase 1
Kisspeptin test for brain function after COVID-19
This study tests how the brain's reproductive hormone system works after a COVID-19 infection using a substance called kisspeptin. It may help explain symptoms like changes in periods or hormone levels in people with long COVID.
Boston, MassachusettsAges 18–60 - NCT04067674Recruiting
Study immune changes in adults with septic shock
This trial looks at how the immune system changes after septic shock in adults in the ICU. It may help doctors better predict or manage complications by studying blood markers a few days after starting treatment.
LyonAges 18 years+ - NCT07536308RecruitingPhase 1
Nasal COVID-19 booster vaccine safety trial
This trial tests a new nasal spray COVID-19 booster vaccine. It aims to see if the vaccine is safe and produces a strong immune response when given through the nose and inhaled, in people who have already been vaccinated.
Decatur, GeorgiaAges 18–64 - NCT07697937RecruitingPhase 2
YH02 injection for advanced solid tumors that didn't respond to treatment
This trial tests a new injection, YH02, directly into tumors for people with advanced solid tumors (like head and neck, breast, or melanoma) that are no longer responding to standard treatments. The goal is to see if it can shrink tumors or slow disease progression.
TianjinAges 18 years+ - NCT00028080Recruiting
Evaluation and treatment for active Lyme disease
This study evaluates and treats people who currently have active Lyme disease, as defined by CDC criteria. It aims to provide expert care and follow-up while studying the disease.
Bethesda, MarylandAges 2–99 - NCT07266831RecruitingPhase 2/Phase 3
Study of islatravir and ulonivirine for new HIV patients
This trial tests two new HIV medications, islatravir and ulonivirine, in people who have never taken HIV treatment before. It aims to see if this combination can safely control the virus.
Los Angeles, CaliforniaAges 18 years+ - NCT07525544RecruitingPhase 1
Safety Study of VH4770359 in Healthy Adults
This is an early-stage safety study testing a new investigational drug (VH4770359) in healthy volunteers. Researchers want to understand how the body processes the drug and ensure it is safe and well-tolerated.
