- NCT07189377RecruitingPhase 4
Light, ex-vivo treatment and antivirals for lungs from hepatitis B donors
This trial tests a new way to safely use donor lungs that carry the hepatitis B virus (HBV). It combines a special light treatment, ex-vivo lung perfusion (cleaning the lungs outside the body), and antiviral medicines to prevent infection in the recipient. If you are on the lung transplant list and have been vaccinated against hepatitis B, this study may help expand your donor options.
Toronto, OntarioAges 18 years+ - NCT07189936RecruitingPhase 2
Testing 2-HOBA for Immune Issues in Long COVID with POTS
This trial tests if a medication called 2-HOBA can help with ongoing immune system issues in people with Long COVID who also have POTS. It aims to reduce fatigue and other symptoms by calming overactive immune responses.
Nashville, TennesseeAges 18 years+ - NCT07190560Recruiting
Study of a treatment for newborns exposed to chikungunya
This trial tests a new treatment (PC-CHIK-V) for newborns whose mothers had chikungunya around the time of birth. The goal is to see if the treatment can prevent or reduce the infection in babies. Babies who are not treated will also be followed for comparison.

Survey on tick-borne encephalitis knowledge for French doctors
This trial asks general practitioners in France to complete a survey about their knowledge of tick-borne encephalitis (a virus spread by ticks that can cause brain swelling). It helps researchers understand how well doctors know about this disease and how to prevent it.
StrasbourgAges 18 years+ - 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+ - NCT07195032RecruitingPhase 4
MMR vaccine safety in kids after heart transplant
This trial tests whether the MMR (measles, mumps, rubella) vaccine is safe and works well for children who have had a heart transplant. It may help protect you from these diseases if you haven't had the vaccine or no longer have immunity.
Kansas City, MissouriAges 1–17 - 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.
Munich, BavariaAges 18–65 - 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.
Badalona, BarcelonaAges 18 years+ - NCT07199998Recruiting
How tampons and cups affect your vaginal health
This study looks at how tampons and menstrual cups affect your body's natural defenses and the healthy bacteria in your vagina. You might join if you are a healthy woman between 18 and 49 who has regular periods and uses or is willing to use these products.
Paris, Île-de-France RegionAges 18–49 - NCT07200193RecruitingPhase 1/Phase 2
Study of CRMA-1001 for chronic hepatitis B
This trial tests a new drug called CRMA-1001 in people with chronic hepatitis B who are already on antiviral therapy. The goal is to see if it can help control the virus better.
LyonAges 18–64 - NCT07202052RecruitingPhase 2/Phase 3
Antibiotics or immunoglobulin for infections in blood cancer
This trial compares two treatments—antibiotics or immunoglobulin (a blood product with infection-fighting antibodies)—to see which better prevents infections in people with certain blood cancers like CLL, multiple myeloma, or non-Hodgkin's lymphoma.
Adelaide, South AustraliaAges 18 years+ - NCT07202065RecruitingPhase 2/Phase 3
Preventing infections with antibiotics or immunoglobulin in blood disorders
This study looks at whether a different dose of IVIg (antibody treatment through the vein) or adding antibiotics can help prevent infections in people with low antibody levels. It's for patients already on steady IVIg who cannot safely stop it.
Adelaide, South AustraliaAges 18 years+ - NCT07202078RecruitingPhase 2/Phase 3
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+ - NCT07202091RecruitingPhase 2/Phase 3
Stopping or extending immunoglobulin therapy to prevent infections
This trial tests whether it is safe to stop or extend immunoglobulin (Ig) therapy for people with low antibody levels, or if switching to preventive antibiotics works just as well to prevent infections.
Adelaide, South AustraliaAges 18 years+ - NCT07202949RecruitingPhase 2
High-dose antibiotics plus methenamine for chronic UTI in women
This trial compares a new treatment approach—high-dose antibiotics combined with methenamine hippurate—against standard care for women with chronic urinary tract infections (UTIs). It aims to find if the combination works better at relieving persistent symptoms like pain and frequent urination.
LondonAges 18 years+ - NCT07203755RecruitingPhase 1
Combination vaccine for whooping cough, Hib, and meningitis
This trial tests a new combination vaccine that protects against whooping cough, Haemophilus influenzae type b (a cause of meningitis and pneumonia), and several types of meningococcal disease (a cause of meningitis and bloodstream infections). It may help reduce the number of shots needed for children.
Shangqiu, HenanAges 2 months–6 years - NCT07203833Recruiting
Vasorin test for shock diagnosis and outlook
This study looks at a protein called vasorin in the blood to see if it can help diagnose and predict outcomes in people with severe shock in the ICU. It compares patients with septic shock (caused by infection) to those with shock from other causes.
AmiensAges 18 years+ - NCT07204457RecruitingPhase 2/Phase 3
Meningococcal vaccine trial for healthy adults 19 to 55 years old
This trial tests a new meningococcal conjugate vaccine (EG-MCV4) in healthy adults to see how well the body's immune system responds and if it's safe. If you qualify, you'd help researchers learn if this vaccine can prevent meningococcal disease.
SeoulAges 19–55 - NCT07204756Recruiting
Remote blood pressure monitoring after pregnancy
