San Francisco, CaliforniaAges 18 years+ - NCT04770584Recruiting
Fear and avoidance study in PTSD and healthy volunteers
This study looks at how people with current PTSD—or people without PTSD—respond to fear and avoiding things they might find threatening. It may help researchers understand these patterns and how they differ after trauma.
Houston, TexasAges 18–70 - NCT04771156RecruitingPhase 4
Ketorolac pain relief during cleft palate repair
This trial tests whether ketorolac (a pain medicine similar to other NSAIDs) helps control pain during palatoplasty, the surgery to repair a cleft palate. It may help make recovery more comfortable for people having their first palate repair.
Houston, TexasAges 6 months+ - NCT04774159RecruitingPhase 3
Low-dose colchicine to lower risk in leg artery disease
This trial tests whether low-dose colchicine can reduce “residual” risk—future heart and blood-vessel problems—in people with peripheral artery disease (PAD). It targets PAD symptoms and complications like poor blood flow in the legs, even after certain procedures.
New Haven, ConnecticutAges 18 years+ - NCT04778761Recruiting
Video program to help with end-of-life care planning
This trial tests a video-based program that helps people with a life-limiting illness plan their future healthcare wishes. If you may benefit, it may make conversations about advance care planning easier and more structured.
Jersey City, New JerseyAges 21 years+ - NCT04783168Recruiting
Using a step-tracking device to improve recovery after lung surgery
This study tests whether tracking daily steps with a wearable and app can help people recover better after lung surgery (especially a lobectomy). You may be asked to wear a device and follow a recovery plan while your activity is monitored.
Houston, TexasAges 18 years+ - NCT04794686Recruiting
Study for children with a brain tumor with multilayer rosettes
This registry research program collects information and tumor samples from people with a specific type of brain embryonal tumor (with multilayer rosettes). It may help researchers understand the tumor better and improve future treatments.
Hackensack, New JerseyAges Any age - NCT04798274Recruiting
Brain wiring study in autism using safe hearing tasks
This study looks at how a brain chemical related to calming signals (“GABA”) may affect how people process sounds in autism. The goal is to understand brain function during hearing tasks, which could help guide future treatments.
Bethesda, MarylandAges 11–25 - NCT04806620Recruiting
Online app study for brain inflammation lifestyle data
This study uses a digital platform (app/website) to collect lifestyle and symptom information to better understand brain inflammation. You may qualify if you have certain conditions like Long COVID, migraines, autoimmune disease, inflammatory gut issues, mood disorders, or if you are a healthy comparison person.
Delafield, WisconsinAges 2 years+ - NCT04811014RecruitingPhase 4
Helping young adults stop opioids after an emergency visit
This study offers an engagement program for young people who tested positive for opioids and meet criteria for opioid dependence. The goal is to help participants stop opioid use safely and learn whether this approach works well in the real-world emergency setting.
Houston, TexasAges 13–17 - NCT04810858Recruiting
Study how chronic marijuana affects brain inflammation in HIV
This study looks at whether ongoing marijuana use changes “brain inflammation” and brain cell injury in people living with HIV. It may help researchers understand potential risks or protective effects and how treatment and brain health interact.
Winston-Salem, North CarolinaAges 25–59 - NCT04811209Recruiting
Testing better pain control and recovery after orthopedic surgery
This trial looks at how well a pain-control plan works after certain orthopedic surgeries and how it affects recovery and patient-reported outcomes. It may help determine what level of pain relief is meaningful to patients after surgery.
Toronto, OntarioAges 18–80 - NCT04814082Recruiting
