Personalized immunotherapy prediction for melanoma and other cancers
This trial is testing a new way to predict which immunotherapy might work best for your cancer. It uses a sample of your tumor to look for personal markers, so your treatment can be tailored to you.
Sydney, New South WalesAges 18 years+ - NCT06537726Recruiting
Breath test for fungal infections in leukemia patients
This trial tests if a simple breath analysis can detect invasive fungal infections early in people with acute leukemia who are undergoing chemotherapy and have a low white blood cell count. Early detection could help start treatment sooner.

Los Altos, CaliforniaAges Any age - NCT06539234Recruiting
Testing angiotensin II for vasoplegic shock
This trial gives a drug called angiotensin II to people in vasoplegic shock (a type of shock where blood vessels stay too relaxed despite other medicines). It tests how the drug affects a kidney-related hormone (renin) and if it can help raise blood pressure.
MariborAges 18 years+ - NCT06539325Recruiting
Rapid testing for fever after travel to the tropics
This trial uses a rapid test to find the cause of fever in people who recently returned from tropical areas. It aims to detect new or unusual infections early, when you are still in the emergency department.
Paris, ParisAges 18–99 - NCT06539832Recruiting
Gut bacteria and immunity in people with an abnormal blood protein
This study looks at how your gut bacteria (intestinal flora) and immune system relate to a condition called monoclonal gammopathy, where an abnormal protein is found in the blood. The trial will check samples from your blood, plasma, and stool to understand these connections.
Guanzhou, GuangdongAges 45 years+ - NCT06541028Recruiting
Quick-start HIV treatment study for people who inject drugs
This study tests a rapid-start antiretroviral therapy (ART) approach for people who inject drugs and have HIV. The goal is to see if starting HIV medicine quickly helps reduce stigma and improve health outcomes.
KajangAges 18 years+ - NCT06543290RecruitingPhase 1
Azithromycin before inducing labor
This study tests whether giving the antibiotic azithromycin before starting labor can help prevent infections in mothers. It is for pregnant women who will have their labor induced for medical reasons or after 39 weeks.

ParisAges 18 years+ - NCT06545838Recruiting
Testing renin levels to predict septic shock severity
This trial checks if a blood test measuring renin (a kidney hormone) can help predict how severe septic shock will be and how well patients recover. It looks for early clues in ICU patients with sepsis.
MoscowAges 18 years+ - NCT06546020Recruiting
Haskap berries for gut and metabolic health
This study tests whether a berry called Haskap can improve your gut health and how that might affect your overall health. Researchers are looking for people with and without certain metabolic risk factors to see who benefits most from adding these berries to their diet.
Bozeman, MontanaAges 35–65 - NCT06546579RecruitingEarly Phase 1
Testing if you can collect your own skin sample for scabies
This study tests whether you can collect your own skin samples at home to help diagnose scabies. If you have or might have scabies, this study could offer an easier, less embarrassing way to check for it.
Nijmegen, GelderlandAges 18 years+ - NCT06550622Recruiting
Better Detection of Hepatitis B Virus After Treatment
