Recruiting studies
- NCT05356182Recruiting

This early study tests whether a device that uses focused ultrasound (guided by MRI) can be safely used during surgery for women with invasive breast cancer. It mainly looks at feasibility—whether the treatment can be delivered as planned and is safe.
Salt Lake City, UtahAges 18 years+ - NCT05267912Recruiting
Using tumor organoids to guide treatment for advanced cancers
This study tests whether growing a patient's tumor cells in a dish (called an organoid) can help doctors choose the best next treatment. It is for people with advanced colorectal or pancreatic cancer who have run out of standard options.
Bordeaux, FranceAges 18 years+ - NCT05303467RecruitingPhase 1
Safety study of a glioblastoma device for recurring tumors
This early study tests whether a device called TheraSphere is safe when delivered into the brain to treat recurrent glioblastoma. It may help patients by trying a targeted treatment approach, while doctors carefully monitor side effects and safety.
Birmingham, AlabamaAges 18 years+ - NCT04587739RecruitingPhase 1
Radiation before surgery for a single liver tumor
This early feasibility study tests a radiation plan given before surgery for hepatocellular carcinoma (a type of liver cancer) to see if it’s safe and doable. It may help shrink or control the tumor before an operation that aims to fully remove it.
LilleAges 18–70 - NCT05230745Recruiting
Test device for heart failure safety and how well it works
This trial studies whether the ContraBand device can be safely placed in people with long-term, symptomatic heart failure and reduced heart pumping. It also looks at whether the approach is practical and tolerable, and gathers early safety information.
AalstAges 18–85 - NCT05245812Recruiting
Robotic nipple-sparing mastectomy safety and feasibility study
This trial looks at whether a robotic technique for nipple-sparing mastectomy is safe and practical to do. It may help your care team understand whether this approach works well for people who are candidates for nipple-sparing surgery.
Dallas, TexasAges 18–80 - NCT05227937Recruiting
Single-dose antibiotic for uncomplicated bladder infection in the ER
This study tests whether giving one dose of amikacin in the emergency department is practical and safe for treating uncomplicated bladder infections. It also looks at how patients do after treatment over the next 3, 7, and 30 days.
Brooklyn, New YorkAges 14–110 - NCT05141487Recruiting
Testing a nerve stimulation trigger for bladder control
This study tests whether a “triggered” nerve stimulation therapy can help people with nerve-related bladder problems hold urine better and empty their bladder more comfortably. It mainly looks at whether the approach is safe and workable for patients.
Cleveland, OhioAges 18 years+ - NCT05190978Recruiting
Test mesh use for breast reconstruction above the muscle
This study tests whether using surgical mesh can be done safely and works well in breast reconstruction done right away, in front of the chest muscle (pre-pectoral) using tissue expanders. It may help improve how the reconstructed area holds up, but you’d need to meet specific surgical and health requirements.
Los Angeles, CaliforniaAges 22–75 - NCT05102110Recruiting
Check rectal mucus in people with throat or lung cancers
This study looks at a substance called rectal mucus during an exam to learn about changes in people with cancers of the throat/airways (aero-digestive tract). It’s a feasibility study, meaning it mainly tests whether this approach is safe and practical.
ExeterAges 18–99 - NCT05103566Recruiting
Noninvasive vagus nerve stimulation for ruptured brain aneurysm bleed
This trial studies whether a noninvasive device that stimulates the vagus nerve can be safely given soon after a ruptured aneurysm bleed to improve outcomes. It may help calm the brain’s stress response after this type of stroke-like emergency.
Boston, MassachusettsAges 18–85 - NCT05077137RecruitingPhase 1
Testing an immune memory boost with checkpoint therapy
This early study tests whether “immune recall” (training the immune system using specific vaccine-like steps) can improve how well checkpoint drugs work for advanced melanoma. It is designed mainly to see if the approach is feasible and safe, and it may help some people respond better to PD-1 (with or without CTLA-4) treatment.
Durham, North CarolinaAges 18 years+ - NCT04472260Recruiting
Testing safe early standing for adults with severe lung failure
This trial checks whether it’s safe and doable to help people with acute respiratory distress syndrome (ARDS) start standing early, while they are closely monitored. It may help some patients begin upright movement sooner, with the goal of improving safety.
OrléansAges 18 years+ - NCT05061004Recruiting
Cephea valve study for severe mitral valve disease
This study tests a new device called the Cephea valve, which is placed through a small tube (catheter) to treat severe leaking or narrowing of the mitral valve. It may be an option for people who are not good candidates for open-heart surgery.
Phoenix, ArizonaAges 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+ - NCT04949464Recruiting
Smoking quit coaching plus lung scans for people with HIV
This study tests a behavior-change program to help people with HIV quit smoking, along with routine low-dose lung CT scans to find warning signs early. It’s a feasibility study, meaning the main goal is to see if the approach is practical and acceptable, and if people can follow through.
La Jolla, CaliforniaAges 45–80 - 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+ - 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.

Common questions
- Are there clinical trials for feasibility?
- Yes. Clin2 currently lists 795 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.
