Recruiting studies
- NCT04587739RecruitingPhase 1

This trial studies whether an at-home stool DNA test (Mt-sDNA) can safely and usefully monitor people after colon or rectal cancer treatment. It’s mainly about whether the test is practical and helpful during routine follow-up.
Cleveland, OhioAges 18 years+ - NCT04634383Recruiting
Testing a brain-connected implant to help some blind people see
This early safety study tests an implanted device placed in the brain to help people with very limited sight (no or minimal light). It focuses on whether the implant can be safely used and whether it may support vision-related signals over time.
Chicago, IllinoisAges 19–70 - NCT04751760Recruiting
Test a new blood test for IgE allergy markers
This study checks whether a new blood test can measure allergy-related immune signals (IgE) in people with known or suspected allergies. If it works well, it could help doctors diagnose and track IgE allergies more easily.
ToulouseAges 6 months–99 years - NCT04782232Recruiting
Study of a new blood tube for heart pump patients
This registry study checks whether a new venous blood tube used with a heart pump is safe and practical for people whose right heart is failing and who may need a heart transplant. If you qualify, your care team would monitor how the device works over time.
MunichAges Any age - NCT04803773Recruiting
MRI-guided ultrasound to treat painful bone tumors
This feasibility study tests an MRI-guided focused ultrasound treatment for certain painful bone tumors, including bone metastases and osteoid osteoma. The goal is to see if the treatment can be safely delivered to the right spot and help with pain.
StrasbourgAges 18 years+ - NCT04882839RecruitingPhase 2
Therapy with psilocybin for severe OCD symptoms
This Phase 2 study tests whether psilocybin-assisted psychotherapy can reduce symptoms in adults with severe, treatment-resistant OCD. It also focuses on safety and whether this approach is practical to run.
BeershebaAges 18–65 - NCT04888247Recruiting
Testing a new mitral valve replacement for high-risk patients
This study checks whether an innovative device can safely replace a damaged mitral valve in people who are higher risk for open-heart surgery. It looks at how well the procedure and follow-up work for improving mitral leakage symptoms.
AuchenflowerAges 18 years+ - NCT04894643Recruiting
Pre-surgery proton radiation plus chemo for borderline pancreatic cancer
This trial tests whether giving proton radiation and chemotherapy before surgery can shrink or control “borderline resectable” pancreatic cancer so it can be removed more effectively. It may help by improving treatment response while planning for surgery afterward.
Wiener Neustadt, Lower AustriaAges 18 years+ - NCT04895995Recruiting
Digital CBT program for anxiety after heart or stroke events
This trial tests a scalable online “CBT” program (a structured talking-therapy approach) to reduce generalized anxiety and related health behaviors in people after a recent heart or stroke problem. If you qualify, it may help you learn tools to manage anxiety and health routines in a convenient digital format.
Boston, MassachusettsAges 18 years+ - NCT04910841Recruiting
Testing a glucose-monitoring device in septic shock ICU
This trial checks whether a continuous glucose monitoring system (“CGM GUARDIAN 2”) can be used safely and effectively for people in the ICU who have septic shock and high blood sugar. It may help the medical team track blood sugar more easily while you receive insulin.
NiceAges 18 years+ - NCT04919980Recruiting
Testing a new mitral valve repair device for high-surgery-risk patients
This study looks at a new way to treat a leaky mitral heart valve using the INNOVALVE system. It’s meant for people who have symptoms from mitral regurgitation but are considered high risk for open-heart surgery, to see if the approach can help safely.
Los Angeles, CaliforniaAges 18 years+ - NCT04929899Recruiting
Test of a learning tool during leukemia maintenance
This study checks whether a tablet-based tool (called PeNAT) can be used by children during the usual maintenance treatment phase for ALL (a type of leukemia). It may help families and clinicians better support care at home or during follow-up by testing how well the tool works in real patients.
Los Angeles, CaliforniaAges 4–18 - NCT07170202Recruiting
Mindfulness for young heavy drinkers
This study tests if learning mindfulness can help young adults who drink heavily cut back on alcohol. You'll practice short, easy mindfulness exercises.
Tallahassee, FloridaAges 18–29 - NCT07091968Recruiting
Text-message support for depression in cancer survivors
This study is testing a text-message program to help cancer survivors who feel depressed get connected to mental health support. The goal is to see if this simple, phone-based approach makes it easier to follow up on a referral for depression care.
Charleston, South CarolinaAges 18 years+ - NCT04962672Recruiting
Tested anesthesia approach for survival in high-grade brain tumors
This study checks whether a specific anesthesia plan used during surgery is practical and safe for people having their first operation for a high-grade brain tumor. If it works well, it may help support better outcomes after surgery.
Toronto, OntarioAges 18 years+ - NCT04978857Recruiting
Virtual reality for people with minimal consciousness
This study tests whether guided virtual reality (“VR”) and other senses-based stimulation can help patients in a state of minimal consciousness become more aware. It focuses on whether the experience is safe and tolerable, with the goal of supporting awakening.
AngersAges 18 years+ - NCT05030207Recruiting
Test a new CT scan method for lung cancer radiation planning
This study tests whether a real-time, breathing-adapted CT scan (called 4DCT) can be done safely and work well for planning radiation treatment for lung cancer. It may help make radiation planning more accurate while checking if the scan process is practical for patients.
Blacktown, New South WalesAges 18 years+ - NCT05035901Recruiting
Handwriting practice program for children with poorer handwriting
This study tests a handwriting practice program designed to improve a child’s handwriting. It may help by teaching skills in a structured way, but it is meant for children whose main challenge is handwriting—not severe brain, sensory, or reading/language problems.
TaipeiAges 7–12 - NCT05056350Recruiting
Coaching to help you return to work after breast cancer

MontpellierAges 18 years+ - NCT05061004Recruiting
Testing a new mitral valve treatment delivered through a catheter
This trial tests a new mitral valve device that may improve blood flow in people with significant mitral valve leakage or narrowing, using a catheter instead of open-heart surgery. It’s meant for patients who doctors think this catheter approach is a better fit than surgery.
Phoenix, ArizonaAges 18 years+ - NCT05099874Recruiting
Computer training to improve attention in sickle cell disease
This trial tests whether a computer-based “attention control” training program can improve attention and daily functioning in children with sickle cell disease. To join, you must meet certain criteria and also pass an initial attention screening test during the study.

Common questions
- Are there clinical trials for feasibility?
- Yes. Clin2 currently lists 804 recruiting feasibility 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 feasibility 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 feasibility 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.
