Recruiting studies
- NCT04451044Enrolling by invitation
Guided heart stent planning using an inside pressure sensor
This study tests whether using a tiny pressure sensor in heart arteries during a procedure can better guide where to place a stent. It may help doctors choose the safest and most effective stent plan by more accurately measuring artery narrowing.
Birmingham, AlabamaAges 18 years+ - NCT04308707Enrolling by invitation
Training surgeons to deliver difficult news better
This study tests a structured “how to break bad news” training tool for doctors and surgical residents. It may help improve how carefully and clearly clinicians communicate in serious situations.
BarcelonaAges 18 years+ - NCT04279496Enrolling by invitation
CT heart scan registry to track outcomes over time
This is a research registry that follows people who are already getting a CT scan of their heart arteries for medical reasons. It aims to better understand how these scans relate to future heart outcomes, while collecting follow-up health information.
Charlottesville, VirginiaAges 18 years+ - NCT04243356Enrolling by invitation
ICU nurse involvement in a post-ICU follow-up clinic
This study looks at whether having ICU nurses actively involved in a follow-up clinic after ICU discharge improves patients’ recovery and follow-up care. It focuses on patients who were cared for in the ICU and the registered nurses who cared for them.
Ann Arbor, MichiganAges 18 years+ - NCT04240119Enrolling by invitation
Study blood vessel growth markers in certain brain artery narrowing
This study looks at “angiogenic markers,” which are blood measures that may reflect how blood vessels grow, in people with significant narrowing of a brain artery. It aims to better understand these changes and how they relate to cerebrovascular disease.
Ages 18 years+ - NCT04147559Enrolling by invitation
Long-term follow-up for a specific hip replacement stem
This study checks how well a particular hip replacement stem (the PROFEMUR Preserve Classic Femoral Stem) and matching parts keep working over many years. You may be invited if you had that exact hip replacement combination and can return for long-term checkups.
Scottsdale, ArizonaAges 21 years+ - NCT04145401Enrolling by invitation
Long-term follow-up for a specific knee revision implant
This study tracks how well a particular knee revision implant performs over many years. It may help you by closely monitoring your knee after revision surgery and adding to long-term safety and performance data.
Englewood, ColoradoAges 21 years+ - NCT04145375Enrolling by invitationPhase 1/Phase 2
Continue the same study drug if it’s helping you
This trial is for people who already finished a Zenith Epigenetics study with the drug ZEN003694 and are still getting benefit. It checks whether continuing the same treatment on schedule is safe and useful for you.
San Francisco, CaliforniaAges 18 years+ - NCT04123457Enrolling by invitation
Study blood and skin samples to improve lymphedema care
This study collects samples (like blood and possibly lymph fluid-related tests) to help doctors better tailor treatment for lymphedema. It may help researchers find ways to improve outcomes for people treated for swollen, fluid-rich tissue.
Jacksonville, FloridaAges 18 years+ - NCT04112355Enrolling by invitation
Tracking children’s immune response after routine vaccinations
This study measures how a child’s immune system responds after standard childhood vaccines, like DTaP-IPV/Hib, pneumococcal, MMR, varicella, flu, and COVID shots. It may help researchers better understand what a “healthy” immune response looks like after vaccination.
Rochester, MinnesotaAges 4 months–21 years - NCT04074356Enrolling by invitation
Tests for esophagus function using noninvasive body measurements
This study looks for noninvasive ways to measure how well your esophagus is moving. It may help doctors better evaluate swallowing and esophagus movement without relying only on invasive testing.
Nashville, TennesseeAges 18 years+ - NCT04064008Enrolling by invitation
Long-term follow-up for a specific hip revision stem
This study follows people who had a hip replacement redone (revision) because of bone healing problems or hardware removal, using a specific revision femoral stem. It checks how the stem does over time and follows up for up to 10 years after surgery.
OtwockAges Any age - NCT04002505Enrolling by invitation
Study for low-risk head injury after a bump to the head
This trial studies people with a recent, blunt head injury who are considered low risk and may be getting a head CT scan. It may help improve how doctors decide when CT scans are needed after a concussion or possible brain bleeding.
Rochester, MinnesotaAges 18–65 - NCT03984591Enrolling by invitationPhase 4
Compare spironolactone vs eplerenone for heart failure patients
This study uses Denmark’s heart failure registry to compare two common tablet medicines—spironolactone and eplerenone—for people with symptomatic systolic heart failure. It aims to see which one leads to better health outcomes over time.
CopenhagenAges Any age - NCT03970005Enrolling by invitation
Step-based program for teens with early signs of psychosis
This trial tests a staged (“step-based”) mental health program for people ages 12–25 who have early warning signs that could develop into psychosis. It may help by targeting symptoms early and reducing the chance of worsening over time.
Columbus, OhioAges 12–25 - NCT03681977Enrolling by invitation
Compare two knee replacement systems for osteoarthritis outcomes
This study compares results from two specific knee replacement systems for people with knee osteoarthritis. It may help find which device works better for pain and function after knee replacement surgery.
Montreal, PQAges 18–80 - NCT03675724Enrolling by invitationPhase 2
Fisetin for frailty and inflammation in older adults
This trial studies whether fisetin, a supplement-like drug, can reduce frailty and inflammation in people age 70 and older. It may help improve health measures related to aging, but you must meet several safety and medication rules to join.
Rochester, MinnesotaAges 70 years+ - NCT03618186Enrolling by invitationPhase 2
Brain scan study for African Americans age 30+
This Phase 2 study uses brain imaging (including PET and MRI) to learn more about brain changes. It may help researchers improve how brain patterns are measured and understood, which could guide future care.
Jacksonville, FloridaAges 30 years+ - NCT03610906Enrolling by invitation
Study of blood/tissue targets in suspected childhood brain tumors
This study looks at biological “targets” (things in the body) to help guide future medical treatments for children and teens with suspected craniopharyngioma. It will collect and analyze tissue samples from planned care to understand what therapies might work best.
Aurora, ColoradoAges 4 weeks–21 years - NCT03576573Enrolling by invitation
Follow-up study for specific hip replacement components
This study checks outcomes after a specific type of hip surgery using specific brand parts. You may help by sharing follow-up visit information so the sponsor can confirm the components work as expected in everyday patients.
BuxtehudeAges 21 years+ - NCT03501589Enrolling by invitation
Medicine aims to help regrowing growth cartilage
This trial is testing a treatment intended to affect the growth plate—the cartilage area that helps bones grow—in people who still are growing. It looks at whether changing signals in the growth plate can improve healing or regrowth after surgery removes part of that area as part of routine care.
Rochester, MinnesotaAges Any age - NCT03432936Enrolling by invitation
Uses Philips iSuite during MRI-guided procedures
This study tests a software tool (Philips iSuite) to help doctors during MRI-guided, minimally invasive procedures. You may be able to participate if you’re already scheduled for this type of procedure, unless you are pregnant.
Rochester, MinnesotaAges 18–90 - NCT03423303Enrolling by invitation
Screening test to find early prostate cancer sooner
This trial checks whether an early prostate cancer screening approach can detect clinically significant prostate cancer sooner. It may help participants catch the disease at an earlier stage when treatment can be more effective.
HelsinkiAges 50–63 - NCT03414242Enrolling by invitation
Neck and brain tests after a sports head or neck injury
This study looks at how sports-related injuries may affect thinking and how well your neck moves and feels strong. You may be eligible if you’re an athlete and can do simple neck movement and strength checks.
