Test of a TB vaccine for newborns in sub-Saharan Africa
This Phase 3 study tests whether MTBVAC can safely protect newborn babies from tuberculosis and whether it helps the baby’s immune system learn to fight TB. If you enroll, the goal is to see safety and immune response in real newborn settings in sub-Saharan Africa.
Worcester, Western CapeAges 5 minutes–1 week - NCT04978571Recruiting
Electrical nerve stimulation for long-lasting concussion symptoms
This study tests whether a device that delivers gentle electrical signals to nerves through the skin can help children and teens with concussion symptoms that have lasted at least 3 months. You may be asked to attend clinic visits for the nerve stimulation setup if you meet the safety and scheduling requirements.
Orange, CaliforniaAges 11–18 - NCT04983251Recruiting
REACH Equity: community support and health action for women
This study looks at women’s health awareness and community resiliency, with an emphasis on environmental health actions. It may help by testing ways to connect people to resources and improve health behaviors in underrepresented communities.
Research Triangle Park, North CarolinaAges 18–100 - NCT04989491RecruitingPhase 4
Single-dose rituximab to prevent EBV after kidney transplant
This trial tests whether one dose of rituximab (given around the time of transplant) can help prevent a first Epstein-Barr virus (EBV) infection and related abnormal lymph node or immune growths after kidney transplant. It is specifically for adults who are EBV-negative before receiving an EBV-positive donor kidney.
StrasbourgAges 18 years+ - NCT04990908Recruiting
Screening children in ICU for immune problems after severe infection
This study checks children in pediatric intensive care for possible “immune system problems” after a severe infection. The goal is to find primary immunodeficiencies early, which may change follow-up and treatment for the child’s immune health.
MontpellierAges 3 months–16 years - NCT05007340Recruiting
ILD and autoimmune conditions registry and sample storage
This study collects health information and may store blood or other samples to learn more about interstitial lung disease (ILD) and autoimmune-related conditions. Joining could help researchers understand different causes of ILD and improve future care.
Montreal, QuebecAges 18 years+ - NCT05013632Recruiting
COVID-19 pregnancy medicine registry for expecting or recent mothers
This study is a registry that collects information about COVID-19 during pregnancy, including what treatments were used and pregnancy outcomes. It may help doctors better understand the safety and effects of COVID-19 medicines in pregnancy.
Los Angeles, CaliforniaAges 18–50 - NCT05013944Recruiting
Join a patient registry to support future research
This trial is a “patient registry,” which collects health information over time to help researchers plan and run future studies. It may help by contributing your experience so new treatments can be tested more effectively.
Arlington Heights, IllinoisAges 18 years+ - NCT05017142Recruiting
Pediatric brain inflammation registry for Swiss patients
This study is a registry that collects health information from children and teens in Switzerland diagnosed with certain inflammatory brain and spinal cord conditions. It helps researchers understand these illnesses better over time and may guide future treatments.
Aarau, Canton of AargauAges Up to 36 years - NCT05017766Recruiting
Study for infections from antibiotic-resistant bacteria
This study looks at new ways to fight antibiotic-resistant bacteria in people with certain common infections. It may help by testing approaches tailored to the specific germs found in your urine, lungs, or deeper infections.
BaselAges 18 years+ - NCT05019495Recruiting
Study to improve quit-smoking support for people with HIV
This trial tests ways to deliver tobacco-quit treatment more effectively for people living with HIV. You may help researchers compare different quit-support approaches to see what works best.
Charleston, South CarolinaAges 21 years+ - NCT05022238Recruiting
Screening for drug-resistant TB hotspots in Namibia
This study tries to find more cases of drug-resistant tuberculosis (TB that doesn’t respond to usual medicines) by checking people in specific regions, households, hospitals, and high-risk “hotspots.” It may help detect TB earlier and link more people to treatment.
WindhoekAges Any age - NCT05022446Recruiting
Survey study on how COVID-19 affected lung procedures
This study is a survey sent to U.S. lung doctors to understand how COVID-19 changed the way certain lung procedures are done. Your answers could help improve future care and planning during respiratory outbreaks.
Houston, TexasAges Any age - NCT05022862Recruiting
Check how incentives and vDOT help latent TB treatment

Study of severe HPV disease and why it keeps coming back
This study follows people with severe or hard-to-treat HPV-related conditions (and some closely related partners/household contacts) to learn how the virus causes illness and how the immune system responds. It may help doctors better predict who will develop severe disease and guide future treatments.
