Recruiting studies
- NCT05758467Enrolling by invitation
Study linking adult oral health, social factors, and heart health
This study looks at how people’s oral health in adulthood relates to social factors and heart health. To join, you must have already taken part in specific past health surveys.
BergenAges 71–72 - NCT05709743Enrolling by invitation
Tests visual switching in healthy adults
This study looks at how people switch attention between different visual targets during a visual search task. It may help researchers better understand how visual focus and thinking work in everyday situations.
Bethlehem, PennsylvaniaAges 18 years+ - NCT05674539Enrolling by invitationPhase 3
Less intense transplant regimen for AML or MDS patients
This trial tests whether a less intense chemotherapy and transplant plan can work for adults with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) who are getting a stem cell transplant. It may help reduce transplant-related harm, especially in people considered higher risk due to age or other health factors.
Wuhan, HubeiAges 18 years+ - NCT05667493Enrolling by invitationPhase 3
Long-term safety follow-up for eplontersen in ATTR heart disease
This is a long-term study to check the safety of eplontersen over time in adults with transthyretin-mediated amyloid cardiomyopathy (ATTR-CM). It is mainly for people who already took the study medication before, or who joined an earlier related study and are doing well.
Scottsdale, ArizonaAges 18 years+ - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.
Baton Rouge, LouisianaAges Any age - NCT05559567Enrolling by invitation
Study for new adults with early myopia and no treatment
This study checks eye measurements (like “axial length,” the distance inside the eye) in adults with new-onset nearsightedness who are not using any myopia-control treatment yet. The results may help guide how myopia-control strategies are best applied.
St Louis, MissouriAges 21–35 - NCT05315596Enrolling by invitation
Tracking pain and recovery answers after surgery
This study checks how patients report pain and recovery over time after surgery. It may help improve how hospitals understand and manage pain after operations.
JenaAges 18 years+ - NCT05307666Enrolling by invitationPhase 4
Older adults using many medications may get simpler care
This study looks at whether older adults do better when their medication plan is simplified. You may be able to join if you’re at least 80, live in the community, and take 6 or more regular oral medications.
Edmonton, AlbertaAges 80 years+ - NCT05183503Enrolling by invitation
Study of pain, stress, anxiety, and depression in jaw disorder
This study looks at how chronic jaw pain from temporomandibular disorder (TMD) relates to stress, anxiety, and depression in adults. Your results may help researchers better understand what affects symptoms and how people respond to care.
WroclawAges 18–80 - NCT04984447Enrolling by invitation
Imaging the small intestine using a tube through the nose
This study uses a thin tube placed through the nose to take pictures of the small intestine. It aims to improve how the gut can be safely viewed without traditional scopes.
Boston, MassachusettsAges 18–60 - NCT04848506Enrolling by invitationPhase 2/Phase 3
Long-term safety follow-up with aficamten for adults with HCM
This study checks how safe and well-tolerated aficamten is over the long run in adults with hypertrophic cardiomyopathy (HCM). You may be eligible if you finished a prior Cytokinetics aficamten study and your heart pumping strength is in the required range.
Birmingham, AlabamaAges 18–85 - NCT04836390Enrolling by invitationPhase 2
Donor immune cell treatment after transplant for high-risk AML
This trial tests an additional immune therapy made from donor natural killer (NK) cells given around the time of a special stem cell transplant for children and young adults with high-risk acute myeloid leukemia (AML). It aims to help prevent the leukemia from coming back or not responding after transplant.
Phoenix, ArizonaAges birth–25 years - NCT04202094Enrolling by invitation
Fertility options for young men after childhood cancer treatment
This study looks at fertility outcomes in young men who had cancer or blood disorders as children and then received high-risk treatment that can affect future fertility. It also compares people who did or did not store testicular tissue through a biopsy when they were younger.
BrusselsAges 18 years+ - NCT04129229Enrolling by invitation
Tongue device study for moderate-to-severe sleep apnea and snoring
This trial tests a tongue retractor device to help treat obstructive sleep apnea and reduce snoring in adults. You may be eligible if you have moderate-to-severe sleep apnea and can avoid other common treatments during the study.
Brighton, MassachusettsAges 18 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+ - 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+ - NCT03628612Enrolling by invitationPhase 2
Long-term follow-up after CAR T cell treatment
This study checks how people do over the long run after receiving a personalized, genetically modified CAR T cell treatment. It may help researchers understand long-term safety and outcomes, which can improve future care.
Miami, FloridaAges 1 year+ - NCT03541135Enrolling by invitation
Study of heart health, diet, and activity in older adults
This study looks at heart health, food, and physical functioning in people age 65 and older living in Madrid. It may help researchers understand how lifestyle affects aging and cardiovascular wellbeing.
MadridAges 65–95 - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT03254667Enrolling by invitation
Track outcomes in adults with moderate-to-severe psoriasis
This study keeps track of how people with moderate-to-severe psoriasis do over time while using Siliq or other approved treatments. It may help researchers understand how treatments compare in real life.
