Starting immunoglobulin for infection prevention in hematology
This trial tests whether giving immunoglobulin to adults with low antibody levels can prevent infections. It aims to compare immunoglobulin with antibiotic therapy or no added treatment for people with blood conditions.
Adelaide, South AustraliaAges 18 years+ - NCT07197138Recruiting
TMS for depression with long COVID
This trial tests whether accelerated TMS (a brain stimulation treatment) can help people with depression who also have long COVID. It may be an option if your depression hasn't improved enough with medication alone.

Stomach decontamination for severe poisoning in the ICU
This trial tests whether giving activated charcoal plus emptying the stomach can help people who are on a breathing machine after severe poisoning. It may lower the amount of poison in the body and improve recovery.
ParisAges 18 years+ - NCT07197164RecruitingPhase 2
Remdesivir for kidney transplant patients with mild COVID-19
This trial tests whether giving remdesivir to kidney transplant patients who test positive for COVID-19 can prevent them from getting severely ill. It is for people who have already had at least three COVID-19 vaccine doses and are scheduled to receive a kidney transplant soon.

Extended antibiotics with methenamine for chronic urinary tract infection
This trial compares a longer, higher-dose antibiotic course combined with methenamine hippurate (a urinary antiseptic) against standard care (low-dose antibiotics or methenamine alone) for women with chronic urinary tract infections. It aims to see if the extended treatment is more effective at relieving persistent symptoms.

SanliurfaAges 18 years+ - NCT04666246Recruiting
Studying breathing effort in people with COVID-19 breathing failure
This study looks at how hard people with COVID-19 are working to breathe when they have serious breathing trouble but are not yet fully on a breathing machine. The results may help doctors better understand breathing support needs and improve care.
ModenaAges 18–80 - NCT06853340Recruiting
Calcium and blood vessel hardening in sepsis shock
This study looks at how calcium buildup in blood vessels and a specific receptor on immune cells might affect recovery from septic shock. It aims to understand if these factors impact how well patients respond to treatment.
AmiensAges 18 years+ - NCT06278337Recruiting
Moesin-associated immunodeficiency study
This study looks at a rare immune system condition caused by changes in the MOESIN gene. It aims to better understand the condition and may help develop future treatments.
Bethesda, MarylandAges 4–80 - NCT06255626RecruitingPhase 1/Phase 2
New COVID-19 booster vaccine study
This trial tests a new type of COVID-19 booster vaccine that targets a protein to help your immune system. It's for people who already had a primary vaccine series and at least one mRNA booster, with the last booster at least 6 months ago.
CréteilAges 18–84 - NCT07184827RecruitingPhase 3
U101 capsules to prevent recurring UTIs in women
This trial tests an oral capsule called U101 to see if it can prevent recurrent urinary tract infections (UTIs) in women who have frequent UTIs. If you've had at least 2 UTIs in the last 6 months or 3 in the last year, you may be able to join.
Chiayi CityAges 20–75 - NCT07191457Recruiting
Testing two head lice treatments for safety and effectiveness
This study compares a new lice lotion to a standard lice shampoo to see how well they work and if they are safe. If you or your child has head lice, participating could help find a better way to get rid of them.
Enid, OklahomaAges 6 months+ - NCT07188038Recruiting
Comparing low vs high breathing tube pressure on diaphragm health
This trial compares two levels of positive end-expiratory pressure (PEEP) in patients on a breathing machine. It looks at how these pressures affect diaphragm function, how well the lungs work, and how efficiently you breathe.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT06944158Recruiting
Antimicrobial resistance study for healthcare workers
This study asks healthcare workers to fill out a simple questionnaire to help understand how antibiotic resistance spreads. It aims to find ways to better protect patients and staff.
AleppoAges 25–65 - NCT07192458RecruitingPhase 2
High vs. Standard Dose Flu Vaccine in Lung Transplant
This study compares a high-dose flu vaccine to the standard dose in lung transplant recipients. It aims to see if a higher dose gives better protection against the flu.
Nashville, TennesseeAges 18 years+ - NCT07189260Recruiting
Breathing exercises to prevent pneumonia after hip fracture
This trial tests whether simple breathing exercises before and after surgery can help prevent pneumonia in people with hip fractures. It is not a medication study—you'd use a small device to help you breathe deeply.
CopenhagenAges 18 years+ - NCT07189208RecruitingPhase 2
