Recruiting studies
- NCT05010343RecruitingPhase 2
Carbon ion radiation guided by scans for prostate cancer
This Phase 2 trial tests whether using detailed scans (PSMA PET/CT and MRI) to guide carbon ion radiation—delivered in a focused way—can treat localized prostate cancer. It may help target the treatment more precisely while avoiding areas that are not involved.
ShanghaiAges 45–85 - NCT04890821Recruiting
Percutaneous ring repair for leaking tricuspid valve
This early study tests a minimally invasive device that helps tighten (repair) the tricuspid valve ring to reduce severe leaking. It may help people who still have symptoms from right-sided heart failure even after taking the best available medicines.
Hackensack, New JerseyAges 18 years+ - NCT04306432Recruiting
Check how cognitive tests change after brain tumor radiation
This trial studies how radiation therapy affects thinking and memory in adults with certain brain tumors. It may help doctors understand which patients are more likely to have cognitive side effects and how to measure them over time.
Copenhagen, Capital RegionAges 18–100 - NCT05289245Recruiting
Registry study for Chinese people with cystic fibrosis
This study keeps a national record of people diagnosed with cystic fibrosis (CF) in China. It aims to better understand CF over time and may help future care by improving how patients are tracked and studied.
Beijing, Beijing MunicipalityAges Any age - NCT04612322Recruiting
Study registry for microvascular angina patients
This registry study collects information from adults with microvascular angina (chest pain from small blood vessels in the heart). It may help researchers better understand how to assess and manage this condition over time.
Mainz, RLPAges 18–85 - NCT04393181Recruiting
Study how donor heart function affects transplant outcomes
This study looks at how well donor hearts work and how that affects outcomes after heart transplantation. It may help transplant teams choose and use donor hearts more effectively.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT03096366Recruiting
Blood flow restriction rehab after ACL knee surgery
This trial studies whether a special exercise method that limits blood flow to the thigh (called blood flow restriction training) can improve quadriceps strength and function during recovery after arthroscopic ACL surgery. If you qualify, you would join a structured physical therapy program and follow the study’s rehab plan.
Houston, TexasAges 14–55 - NCT05307367Recruiting
Study exercise and body muscle changes in advanced lung cancer
This study looks at why cancer can cause loss of muscle in people with advanced non–small cell lung cancer, and whether exercise can improve or explain those muscle changes. You may be asked to do physical testing and answer questionnaires while receiving standard palliative cancer treatment.
Copenhagen, DKAges 18–100 - NCT05459090Recruiting
Study of how brain “brakes” work in drug-resistant temporal epilepsy
This study looks at how the brain’s natural “braking” system works in people with drug-resistant temporal lobe epilepsy. It may help researchers better understand the condition in order to improve future treatments.
Pozzilli, IserniaAges Any age - NCT05281887Recruiting
Study of eye changes after ischemic stroke
This trial looks at how changes in the retina (the light-sensing tissue in the back of the eye) track with vision and eye function after an ischemic stroke. The goal is to understand which eye changes are linked to the stroke, which could help doctors monitor recovery.
Guangzhou, GuangdongAges 18 years+ - NCT05412823Recruiting
Testing neurologic function after emergency breathing tube placement
This study looks at how well a person’s brain and nerve function works after doctors place an emergency breathing tube. It may help improve care after urgent intubation, especially for people who were functioning fairly well before the event.
JeddahAges 18 years+ - NCT03206190Recruiting
Study for early SPG4 symptoms in family members
This study looks at people in families with a known SPG4 gene change (a SPAST mutation) to understand early, subtle signs and the beginning of symptoms. It may help researchers find better ways to detect SPG4 earlier, before full walking problems start.
TübingenAges 18–70 - NCT03240328RecruitingPhase 1
CAR-T therapy study for rebuilding HIV immune defenses
This early-stage study tests whether CAR-T cells can help rebuild the immune system’s ability to fight HIV. You may be a candidate if your HIV is well controlled on standard treatment and you don’t have certain serious infections or organ problems.
Guangzhou, GuangdongAges 18–60 - NCT05539781Recruiting
Blood flow and brain function monitoring after carotid procedure
This trial studies how blood flow and brain function change after a carotid artery revascularization procedure (opening a narrowed carotid artery). It may help doctors understand what to expect after treatment, especially in people with significant artery narrowing.
Beijing, Beijing MunicipalityAges 18–85 - NCT05553093RecruitingPhase 4
Tirzepatide vs insulin for diabetes and brain effects
This study tests how tirzepatide and insulin glargine affect blood sugar, fat metabolism, and brain function in adults with type 2 diabetes. It may help researchers learn which treatment changes diabetes-related body and brain processes.
Nanjing, JiangsuAges 18–75 - NCT05228262Recruiting
Testing blood-vessel function and muscle strength in osteoporosis
This study looks at how well your blood vessels work and how strong your muscles are, in women after menopause with osteoporosis. You may be asked to start standard osteoporosis treatment, and the researchers will study pain and changes related to vascular function and sarcopenia (loss of muscle and strength).
Clermont-FerrandAges 50 years+ - NCT05009433Recruiting
Exercise plans in pregnancy and afterward for mom and baby health
This study compares two types of exercise—short, intense intervals versus moderate steady activity—during pregnancy and looks at effects on mothers and children. It also checks how participants do on health, fitness, and well-being tests before, during, and after pregnancy.
Gdansk, Pomeranian VoivodeshipAges 18–45 - NCT04883502Recruiting
Testing a technique to rebuild bone lost after injury
This study looks at a surgical method that creates an “induced membrane” to help rebuild bone after traumatic injury. It may help people whose limb bones were damaged and are missing part of the bone.
ClamartAges 18 years+ - NCT03981653Recruiting
Placenta study around normal third-trimester pregnancy
This study looks at how the placenta is working in pregnancies that are planned for cesarean delivery after at least 37 weeks. Researchers compare different pregnancy situations (including some common complications) and check placenta function to better understand placental health.
CréteilAges 18 years+ - NCT05619068Recruiting
Study tracking outcomes in Moyamoya disease

Beijing, Beijing MunicipalityAges 10–60 - NCT04858347Recruiting
Study of a specific knee implant and recovery outcomes
This trial looks at how well a particular knee replacement (a GEMINI SL fixed-bearing prosthesis) works and how people function after surgery. It may help doctors learn what to expect for recovery and long-term results with this implant.

Testing blood pressure targets during heart-lung bypass
This trial compares different strategies for keeping a specific blood pressure level during heart-lung bypass surgery. It may help reduce complications by finding the safest blood pressure target during the operation.

Check how two bowel-reconstruction options affect daily life
This study looks at how surgeons rebuild the esophagus using either a jejunum (small intestine) or a colon (large intestine) piece, and how that affects your day-to-day function and quality of life. It may help doctors choose the approach that best supports recovery and independence for patients needing esophageal reconstruction.

Common questions
- Are there clinical trials for functionality?
- Yes. Clin2 currently lists 2,474 recruiting functionality 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 functionality 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 functionality 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.
