- NCT05732779Recruiting
App-based check-ins to help teens take transplant medicines

Study of flexible care plans across hospitals
This study compares how flexible, integrated treatment projects are carried out across different hospitals nationwide. It’s mainly looking at what happens in routine care, so it may help improve how future care is organized.
MagdeburgAges Any age - NCT05836103Recruiting

Baltimore, MarylandAges 18–30 - NCT05815199Recruiting
E-cigarettes to help smokers with serious mental illness cut down

Phone app support for families before pediatric ear-nose-throat surgery
This trial tests whether a mobile phone app can better support caregivers of children going into tonsil and/or adenoid surgery (sometimes with ear tube placement) around the time of the operation. It may help families feel more informed and prepared before and after surgery.
TriesteAges 2–10 - NCT05696691RecruitingPhase 2/Phase 3

San Antonio, TexasAges 18–70 - NCT05674513RecruitingPhase 4
Study how metabolism differences affect emergency contraception
This trial looks at whether differences in how your body processes a certain emergency contraceptive can change how well it works. You may be asked to provide a progesterone blood test during your cycle to confirm that ovulation is happening.
Portland, OregonAges 18–40 - NCT05840900Recruiting
Mindfulness and optimism program for first-time pregnancy wellbeing
This study tests a mindfulness- and optimism-focused program to support wellbeing and resilience during pregnancy. It may help people, especially those who naturally feel less optimistic, learn stress-support skills during early pregnancy.
Providence, Rhode IslandAges 18 years+ - NCT05484804Recruiting

Chapel Hill, North CarolinaAges 12–99 - NCT05463120Enrolling by invitation
Follow-up study of early growth and puberty timing
This study follows families from an earlier infant feeding study to better understand what affects when puberty starts. It looks at growth and hormone-related health information to explain differences in pubertal development.
Bethesda, MarylandAges 8–100 - NCT05525676Recruiting
Couple check-ins to help reduce suicide risk

Evanston, IllinoisAges 18 years+ - NCT05534321RecruitingPhase 1/Phase 2
Preventive radiation for high-risk spinal bone metastases
This trial tests whether preventive (before serious problems happen) radiation to the spine can help people with high-risk, mostly symptom-free bone metastases. It may reduce the chance of pain escalation or dangerous complications from cancer in the spine.
Miami, FloridaAges 18 years+ - NCT05509933RecruitingPhase 3
Budesonide to prevent engraftment syndrome after stem cell transplant
This Phase 3 study tests whether budesonide can prevent “engraftment syndrome” after people receive a hematopoietic (blood-forming) stem cell transplant. If it works, it may reduce complications around the time the new cells start growing and making blood cells.
Detroit, MichiganAges 18–80 - NCT05407623Recruiting
Behavior game program for Swedish elementary classrooms
This trial tests whether a structured “good behavior game” helps improve the classroom environment in Swedish elementary schools. It targets regular classes in early grades and is delivered by participating teachers, with the school supporting measurements and parent communication.
StockholmAges 6–10 - NCT05426928Recruiting
Study of body heat modeling during HIPEC surgery

Detroit, MichiganAges 18 years+ - NCT05581745Recruiting
Testing a lung transplant approach for certain blood type O patients
This study looks at lung transplants for people getting their first transplant who are blood type O and have low levels of antibodies that may react to donor tissue. It may help doctors choose the safest donor-recipient match for these patients.
Toronto, OntarioAges 18 years+ - NCT05570552Recruiting
Testing health impacts in adults from smoky, arsenic-exposed homes
This study follows adults who took part in an earlier GEOHEALTH study and live in homes that use traditional stoves, with low-to-moderate arsenic exposure in drinking water. It aims to understand how these environmental factors affect health, and what changes might be possible.
DhakaAges 25–70 - NCT05368571Recruiting
CHOICES program for teens at risk of pregnancy and STIs

Houston, TexasAges 14–19 - NCT05350540RecruitingPhase 2
ICG dye to lower leakage after salvage laryngectomy surgery
This study tests whether using a special fluorescent dye (ICG) during salvage laryngectomy can reduce the chance of a surgical “leak” (a fistula) in the throat area. If you’re having salvage surgery after prior radiation, it may help surgeons better see where to place tissue coverage to prevent complications.
Toronto, OntarioAges 18 years+ - NCT05316571Recruiting
