Tracking outcomes during non-heart procedures in children with heart defects
This study looks at how children with congenital heart disease do during routine non-heart procedures, including medical or minor treatments that are not heart-related. It also measures how much health care they use afterward, which may help improve care planning for families.
Los Angeles, CaliforniaAges Up to 21 years - NCT04664569Recruiting
Study of treatments for bacterial meningitis in children
This study enrolls children and newborns with suspected or confirmed bacterial meningitis. The goal is to understand and improve care for serious infections that affect the lining around the brain.
CréteilAges 1 day–18 years - NCT04519229Enrolling by invitation
Feasibility study of child-parent therapy for foster infants and toddlers
This study tests whether a therapy program called Child-Parent Psychotherapy is practical and helpful for very young children in foster care and the adults caring for them. It’s mainly a “feasibility” study, meaning it focuses on whether the program can be delivered and followed in real life.
VaxjoAges birth–6 years - NCT04535661Recruiting
Study of who develops carbapenem-resistant infections in PICU children
This study looks at factors that make some hospitalized children in the pediatric intensive care unit (PICU) develop or carry germs called carbapenem-resistant Enterobacteriaceae. It aims to understand who is at higher risk and why, which may help prevent infections in the future.
Shanghai, Shanghai MunicipalityAges 4 weeks–18 years - NCT04532346RecruitingEarly Phase 1
Hydroxychloroquine for genetic lung disease in children
This early-phase trial studies whether hydroxychloroquine can help children with certain genetic causes of interstitial lung disease (lung scarring/inflammation). It is designed for kids who are currently stable and have not recently taken hydroxychloroquine.
Shanghai, Shanghai MunicipalityAges 1 month–18 years - NCT04504227Recruiting
Testing thickened feeds to improve safe swallowing
This study looks at how using thickened feeds may change swallowing safety and function in children who have swallowing problems (dysphagia) or who are at risk for a type of concerning breathing event. The goal is to see whether thicker liquids help protect the airway and improve swallow patterns.
Boston, MassachusettsAges Up to 21 years - NCT04398901Enrolling by invitation
Study of brain and development outcomes after Zika exposure
This study follows children to compare development in kids exposed to Zika before birth versus similar children not exposed. The goal is to understand what effects Zika exposure may have on early brain development and long-term outcomes.

New treatment strategy for children with newly diagnosed liver cancer
This Phase 3 study tests a modified treatment plan for children newly diagnosed with hepatoblastoma, a type of liver cancer. It may help improve how well treatment works and how safely it can be given by using a structured approach.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT04477460Recruiting
Testing thicker feeds for babies after unexplained brief events
This trial looks at whether using thicker baby feeds can improve health outcomes for infants who have had their first “brief resolved unexplained event” (a short episode with no clear cause). It may help babies who are being monitored after this first episode.
Boston, MassachusettsAges birth–1 year - NCT04391335Recruiting
Breathing tests to spot lung scarring after stem cell transplant
This study checks new ways to measure breathing in children who had a stem cell transplant to better detect a lung condition called bronchiolitis obliterans syndrome. If you join, you’ll do breathing and imaging tests, and researchers will look for patterns that may help with diagnosis.
Toronto, OntarioAges 6–18 - NCT04461821Recruiting
Breath test to study disease in children
This study uses a special machine to analyze exhaled breath to learn about different illnesses in children and teens. It may help researchers find breathing “signals” that reflect conditions like breathing problems, nervous system issues, or new/worsening type 1 diabetes.
BaselAges Up to 22 years - NCT04414046RecruitingPhase 2
Stem cell transplant using T-cell cleanup for immune and metabolism disorders
This Phase 2 study tests a specialized stem cell transplant that removes certain “T-cells” (a type of immune cell) to treat children with serious immune system or inherited metabolic problems. The goal is to improve or stabilize disease by resetting the immune system and supporting the body’s function.
St. Petersburg, FloridaAges Up to 21 years - NCT04356469RecruitingPhase 2
Donor stem cell transplant for serious blood disorders in children
This trial tests a special type of donor stem cell transplant (with donor T-cells removed) to treat serious non-cancer blood problems in children. It may help by resetting the bone marrow so the body can make healthy blood cells again.

Common questions
- Are there clinical trials for children, only?
- Yes. Clin2 currently lists 2,992 recruiting children, only studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a children, only trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a children, only trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
