Recruiting studies
- NCT04772170Recruiting
Study wearable and symptom monitoring during respiratory virus challenges
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
Bethesda, MarylandAges 18–65 - NCT04781322RecruitingPhase 1
Study drug to reduce LDL cholesterol effects in heavy drinkers
This Phase 1 study tests how safe a cholesterol-lowering antibody (alirocumab) is in people who drink heavily but are not seeking alcohol treatment. It also looks at early drug effects in the body to see how it might change cholesterol-related signals.
Bethesda, MarylandAges 21–65 - NCT04799301RecruitingPhase 1
Measure how much sugar you eat using blood and hair samples
This Phase 1 study tests whether “biomarkers” in your blood and hair can accurately measure how much sugar you consume. It may help researchers find better ways to track dietary sugar intake in future nutrition and health studies.
Phoenix, ArizonaAges 18–65 - NCT03894917Recruiting
Study blood and imaging features in older adults with liver cancer
This study looks at what liver cancer is like in newly diagnosed people who are older and whose cancer cannot be removed by surgery. It may help doctors better understand disease behavior and how treatments may work and affect the body.
San Antonio, TexasAges 18 years+ - NCT04071847Recruiting
Study tracking results after Abbott deep brain stimulator surgery
This study follows people who are getting a new Abbott deep brain stimulator (DBS) device or replacing the battery/implantable pulse generator to see how outcomes change over time. It mainly applies to certain DBS targets and diagnoses, and it uses follow-up visits to track results.
Tucson, ArizonaAges Any age - NCT04640987RecruitingPhase 1
Stem cell transplant with added T-cells for blood cancers
This Phase 1 study tests a stem cell transplant plan that uses donor T-cells that have been specially processed and then added back. It aims to see if this approach is safer and works better for children and adults with serious blood cancers who need a transplant.
Palo Alto, CaliforniaAges 1 month–45 years - NCT04851015RecruitingPhase 3
Low-dose TMP-SMX for Pneumocystis pneumonia (PCP)
This Phase 3 study tests whether low-dose trimethoprim-sulfamethoxazole (also called TMP-SMX) can treat Pneumocystis pneumonia (PCP) in people with weakened immune systems. It may help improve treatment while reducing side effects compared with standard dosing.
Montreal, QuebecAges 18–100 - NCT04791748Recruiting
Virtual reality balance training for kids with inner-ear problems
This study uses virtual reality tasks to understand and compare balance and movement in children with long-term inner-ear (vestibular) problems versus those without. It may help doctors learn what supports best balance and safety during daily activities.
ParisAges 7 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+ - NCT04809688Enrolling by invitation
Study how berries affect metabolism and gut bacteria
This study looks at whether eating Saskatoon berries changes how your body uses energy (metabolism) and how your gut bacteria behave. It’s done in healthy people and may help researchers understand how foods could support overall health.
Winnipeg, ManitobaAges 18–75 - NCT04797286RecruitingPhase 2
Sildenafil for early lung blood-pressure problems in scleroderma
This trial tests whether sildenafil can improve early “high pressure in the lung blood vessels” in people with scleroderma. It may help slow worsening breathing and lung blood-vessel disease before it becomes severe.
New Orleans, LouisianaAges 18 years+ - NCT04785443RecruitingPhase 3
Check whether dye-guided imaging helps find parathyroid glands
This study tests whether using a special camera with a fluorescent dye (called ICG angiography) during total thyroid surgery can help doctors find the parathyroid glands more reliably. It aims to lower the risk of “low parathyroid hormone,” which can lead to low calcium after surgery.
BrestAges 18 years+ - NCT04786223Enrolling by invitationPhase 2
Testing an anti-inflammatory PET imaging treatment in memory loss
This Phase 2 study tests whether targeting “neuroinflammation” (inflammation in the brain) can help in Alzheimer’s disease and related memory disorders. You may help researchers by doing several brain scans (including a special PET/CT scan) along with MRI and amyloid imaging to understand what’s happening in the brain.
Rochester, MinnesotaAges 60 years+ - NCT04848025Recruiting
Custom 3D stents made for blocked airways
This trial studies a computer-planned, custom-made 3D stent to open up narrow, blocked areas of the main airway near the chest. It may help reduce breathing trouble and cough, and prevent complications from the blockage.
Toulouse, ToulouseAges 18 years+ - NCT04778046RecruitingPhase 2
Study lung pressure treatment for people waiting for transplant
This Phase 2 trial is for adults with pulmonary hypertension who are on the lung transplant waiting list at Duke. It aims to test whether the study treatment can improve lung pressure and related health outcomes, while using things like MRI to monitor changes.
Durham, North CarolinaAges 18 years+ - NCT04809506Recruiting
Blood and genetic tests to predict future heart problems
This study looks for new body markers (including possible genetic traits) to better predict who is likely to have future cardiovascular events. Your results could help doctors estimate risk and choose prevention strategies more accurately.
ToulouseAges 18–99 - NCT04812314Recruiting
Study how exercise changes body fat and metabolism
This study looks at how starting exercise changes the structure and function of body fat. It may help you understand how exercise affects things like cholesterol and blood sugar, even if you’re not currently exercising regularly.
Ann Arbor, MichiganAges 18–40 - NCT04815694Recruiting
MRI-guided radiotherapy for rectal cancer
This trial tests whether using MRI scans to guide radiotherapy can improve treatment for people with a certain type of rectal cancer. It focuses on patients whose tumors have not spread to other parts of the body and who have specific tumor features seen on MRI.
Roma, RomaAges 18 years+ - NCT04794530RecruitingPhase 3
Cocoa extract trial for walking problems in blocked leg arteries
This Phase 3 study tests whether cocoa extract (cocoa flavanols) can improve walking ability and circulation in people with peripheral artery disease (PAD). It may help people who have PAD-related walking limits and can safely avoid competing cocoa sources and caffeine.
Chicago, IllinoisAges 55 years+ - NCT04816773Enrolling by invitation
Long-term follow-up for specific knee replacement parts
This study follows people for up to 10 years after a knee replacement done with specific manufacturer parts. It helps the company and doctors understand how well these knee implants work and whether they cause any long-term problems.

Study of enzyme therapy for children with infant-onset Pompe disease
This trial tests how well a new enzyme treatment (cipaglucosidase alfa with miglustat) works and how safe it is in children and babies with infant-onset Pompe disease. It may help by improving muscle function after earlier treatment or, for some babies, starting treatment when no prior enzyme therapy has been given.
Gainesville, FloridaAges Up to 17 years - NCT04838171Recruiting
Study of White Blood Cells in Donors and Patients
This study looks at white blood cells (the body’s immune cells) to learn more about how they behave in health and/or illness. Participation may help researchers understand immune-related changes and support future treatments.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,353 recruiting disease 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 disease 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 disease 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.
