Study of a stent for narrowed lung blood vessels
This study looks at a stent called PALMAZ MULLINS XD that is placed in the lung's blood vessels to help keep them open. It aims to see how well the stent works in real-world use for people with pulmonary artery stenosis.
Sacramento, CaliforniaAges Any age - NCT07097740Recruiting
Study of a new polymer heart valve for mitral or aortic replacement
This study tests a new type of prosthetic heart valve made from a special polymer material. It is for adults who need surgical replacement of either the mitral or aortic valve.
Shanghai, Shanghai MunicipalityAges 50 years+ - NCT07085299Recruiting
Gut bacteria and recovery in brain artery narrowing
This study looks at how the bacteria in your gut might affect outcomes in people with narrowed brain arteries. Researchers will track your health over time to see if there are links between your gut bacteria and your recovery.
Nanjing, JiangsuAges 30–80 - NCT07057297Recruiting
Tracking Artery Narrowing After Carotid Surgery
This study follows patients who have had carotid artery surgery to see if the artery narrows again. It helps doctors understand how well the surgery works over time.
PragueAges 18–90 - NCT07045714Recruiting
Endoscopic back surgery for spinal stenosis
This study looks at a newer, less invasive type of back surgery called endoscopic laminotomy. It may help people with lumbar spinal stenosis (narrowing of the spinal canal) who still have leg or back pain after trying physical therapy and pain medicines for at least 3 months.
San Pedro Garza García, Nuevo LeónAges 18–74 - NCT07052071Recruiting
TAVI's effect on gut bacteria in aortic stenosis
This study looks at how a heart valve procedure called TAVI affects the bacteria in your gut. It may help doctors understand how the procedure impacts your overall health.
AthensAges Any age - NCT07034157Recruiting
Ultrasound screening and treatment for artery disease
This study tests if using ultrasound to screen for blocked neck and head arteries can improve treatment plans for people getting heart artery stents. It aims to find hidden blockages and tailor therapy to reduce stroke and other risks.
BeijingAges 18 years+ - NCT07036991Recruiting
Comparing two treatments for narrowed neck arteries
This trial tests whether adding a PCSK9 inhibitor to a statin is better than a statin alone for people with mild-to-moderate narrowing of the carotid artery (the main artery in the neck). It looks at how well these treatments slow plaque buildup and prevent strokes.
ShanghaiAges 18 years+ - NCT07026552Recruiting
Ligament study for lumbar spinal stenosis
This study looks at the ligament in your lower back to understand how lumbar spinal stenosis develops. It involves analyzing tissue samples and may help find better ways to treat this condition.
Rome, RMAges 50–85 - NCT07007663Recruiting
Directional preference in lumbar spinal stenosis
This study looks at whether people with lumbar spinal stenosis (a narrowing in the lower spine) have a 'directional preference'—a specific movement or position that eases their symptoms. If you have leg or buttock pain when walking, this trial may help find better ways to treat your condition.
Lake Success, New YorkAges 48 years+ - NCT07001800RecruitingPhase 2/Phase 3
Slowing aortic valve disease with ataciguat
This trial tests a new pill, ataciguat, to slow down the progression of moderate calcific aortic valve stenosis (a condition where your aortic valve stiffens). If you have moderate valve narrowing and meet the other criteria, participation could help find a way to delay needing surgery.
Birmingham, AlabamaAges 50 years+ - NCT06394089Recruiting
Spine surgery study for stenosis with mild slippage
This study tests a minimally invasive spine surgery (unilateral biportal endoscopy) to see if it works well for people with lumbar spinal stenosis who also have a mild vertebra slippage (spondylolisthesis). The goal is to improve leg symptoms like pain or numbness when walking.
Beijing, Beijing MunicipalityAges 50–80 - NCT06950242Enrolling by invitation
Laser balloon for narrowed brain arteries
This trial tests a new laser balloon catheter to widen narrowed arteries in the brain that cause stroke symptoms. It may help if you have a severely blocked artery and are healthy enough for the procedure.
Changzhou, JiangsuAges 18–80 - NCT05922137Recruiting
ORIENT diet for brain blood vessel narrowing
This trial studies whether a specific dietary program (the ORIENT diet) can improve brain-related thinking and memory in people with narrowed brain or neck arteries. You may be able to help test whether the diet is safe and beneficial alongside usual care, through repeated assessments over time.
Hangzhou, ZhejiangAges 40 years+ - NCT06935201Recruiting
Digital rehab program for spinal stenosis surgery recovery
This study tests a digital, person-centered rehab program to help people recovering from surgery for lumbar spinal stenosis become more physically active. It aims to see if an online program can improve recovery and quality of life after surgery.
StockholmAges 18 years+ - NCT04552145Recruiting
Physical therapy versus surgery for lumbar spinal stenosis
This study compares physical therapy to surgery to help relieve symptoms from narrowing in the lower spine. It looks at which treatment works best for walking discomfort caused by spinal stenosis.
LillehammerAges 50–80 - NCT06907849Enrolling by invitationPhase 2
Imaging amyloid in spinal stenosis and carpal tunnel
This trial tests a special scan that uses a radioactive tracer to look for amyloid protein deposits in people who have had surgery for lumbar spinal stenosis (narrowing of the spine in the lower back) or carpal tunnel syndrome. The goal is to see if the scan can detect these deposits, which may be linked to ongoing orthopedic issues.

Common questions
- Are there clinical trials for stenosis?
- Yes. Clin2 currently lists 495 recruiting stenosis 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 stenosis 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 stenosis 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.
