Chicago, IllinoisAges 18–70 - NCT06311513RecruitingPhase 4
Concentrated bone marrow injection during repeat ACL surgery
This study tests whether adding a concentrated bone marrow injection during repeat ACL surgery helps healing and recovery better than surgery alone. If you have had a previous ACL reconstruction that failed, you may be eligible.
Atlanta, GeorgiaAges 18–55 - NCT06697314Recruiting
Clot removal for acute pulmonary embolism with heart strain
This study tests a new device (AlphaVac) that removes blood clots from the lungs using a thin tube inserted through a vein. It may be an option for people with acute pulmonary embolism who have signs of heart strain or low blood pressure.
PoznanAges 18 years+ - NCT06951724Recruiting
New device to remove blood clots during a heart attack
This trial tests a special catheter designed to suction out blood clots from the heart's arteries during a heart attack. It may help restore blood flow and limit heart damage.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06164639Enrolling by invitation
Biomarkers and causes of lung injury from reflux
This study looks at why some people on breathing tubes develop lung damage from stomach acid getting into the lungs. It may help find better ways to prevent or treat this injury.
ShanghaiAges 18–99 - NCT06747117Recruiting
Removing blood clots in leg arteries with the Indigo system
This study tests a device that vacuums out blood clots from blocked leg arteries, potentially restoring blood flow without open surgery.
Scottsdale, ArizonaAges 18 years+ - NCT04716803Recruiting
BMAC injection for severe knee osteoarthritis before knee surgery
This trial studies injecting “bone marrow aspirate concentrate” (BMAC) into the knee to help relieve pain from severe knee osteoarthritis. It’s for people who have strong signs of advanced arthritis on X-ray and still have ongoing pain despite usual treatments, before a planned knee procedure.
La Jolla, CaliforniaAges 45–75 - NCT07513493RecruitingPhase 4
Comparing two endometrial biopsy tools for women
This study compares two different devices used to collect tissue samples from the uterus (endometrial biopsy). Doctors use these samples to check for cancer or other problems when women have abnormal bleeding or other concerning symptoms. The trial will help determine which device works better and causes less discomfort.
Brooklyn, New YorkAges 18–95 - NCT07088510Recruiting
Surgery options for early pregnancy loss
This study compares two surgical procedures for removing pregnancy tissue after an early miscarriage: hysteroscopic resection and manual vacuum aspiration. It helps you understand which method might work best.
Cleveland, OhioAges 18–55 - NCT02647177Recruiting
Blood and cyst fluid study for pancreatic cyst conditions
This study looks for “biomarkers,” or measurable lab signals, in blood and (when available) cyst fluid to understand pancreatic cyst problems and related conditions. It may help doctors better predict what these conditions are and how to manage them.
Houston, TexasAges 18–100 - NCT07386548Recruiting
Biologic injection for low back disc problems
This study tests if an injection can help people with a herniated disc in the lower back who have not gotten better with other treatments and are already planning surgery. It aims to see if the injection can reduce symptoms and possibly avoid or improve surgery outcomes.
Manhattan, New YorkAges 18 years+ - NCT04212494Recruiting
Aspirating clot during heart procedure for certain heart attacks
This trial studies whether removing (“aspirating”) a blood clot during an emergency heart procedure works better for people having a specific type of heart attack with a large clot burden. It may help improve blood flow after treatment, but it is only for patients who meet several timing and safety conditions.
Fuzhou, FujianAges 18 years+ - NCT04852588Recruiting
Sample chest lymph nodes during treatment for advanced lung cancer
This study checks lymph nodes in the chest (using a camera-guided test) in people with advanced non-small cell lung cancer who are getting curative-intent radiation. The trial may help doctors better confirm how far the cancer has spread and guide the best radiation treatment plan.
London, OntarioAges 18 years+ - NCT05108896Recruiting
Testing breathing and swallowing recovery after ICU breathing support
This study looks at aspiration (food or liquid going “the wrong way” into the airway) in people who survived a serious ICU breathing problem. It may help doctors better support safe swallowing and breathing recovery after being on a breathing machine.
Stanford, CaliforniaAges 18 years+ - NCT05320263Recruiting
Thrombectomy timing: aspiration tube vs stent for basilar stroke
This trial compares two ways to remove a blockage in the brain’s basilar artery: suction (aspiration) versus a retriever stent. It may help doctors learn which approach works better for restoring blood flow in acute stroke patients.
BordeauxAges 18 years+ - NCT05455359RecruitingPhase 4
Tube-fed children at high risk for aspiration pneumonia
This Phase 4 study looks at gastrointestinal movement (dysmotility) and how it may increase the risk of aspiration pneumonia in children who eat through a tube and have swallowing safety problems. It may help doctors better prevent lung infections in children who cough/choke and need suction often.
Boston, MassachusettsAges 5–21 - NCT05554588Recruiting
Thrombus-finding treatments for heart attack during angioplasty
This trial compares two ways to remove or break up a blood clot during emergency heart artery opening (primary PCI) for a specific type of heart attack (STEMI). It may help patients with a high clot burden by testing whether one approach works better than the other to improve outcomes.
Beijing, Beijing MunicipalityAges 18–80 - NCT05674643Recruiting
Gastric testing during children’s surgery
This trial studies how the stomach is working in children around the time of surgery. It may help improve how doctors assess and manage stomach function to make surgery safer and more comfortable.
Boston, MassachusettsAges 2–18 - NCT05711849RecruitingPhase 2
Stem cell treatment for long-lasting chest pain not helped by meds
This Phase 2 trial tests whether stem cells placed into the heart artery can safely reduce symptoms in people with “refractory” angina (chest pain) despite maximum heart-healthy medication. You may qualify if your chest pain is limiting your activity and other heart procedures (stents/bypass) aren’t possible or are too risky.
London, EnglandAges 18 years+ - NCT05789940Recruiting
