Recruiting studies
- NCT06511583Recruiting
Bronchoscopy for aspiration pneumonia in the ER

PoznanAges 18 years+ - 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 - 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 - NCT05985785Recruiting
Bone Marrow vs Steroid Injection for Knee Arthritis
This study compares two different knee injections—one using your own concentrated bone marrow cells (BMAC) and the other using a steroid (cortisone)—to see which works better for long-term knee pain from osteoarthritis.
Chicago, IllinoisAges 18–70 - NCT04418258Recruiting
Test a new scope suction catheter during endoscopy
This study tests a special aspiration (suction) catheter used during an upper GI endoscopy to see how well it works during routine care. It may help doctors improve how they clear fluid or residue during the procedure.
Los Angeles, CaliforniaAges 18–85 - 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 - 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+ - 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+ - NCT06003101RecruitingPhase 3
Blood treatments for hip labrum tear surgery
This study tests whether adding platelet-rich plasma (a blood concentrate), platelet-poor plasma, or bone marrow concentrate during hip surgery helps people with a torn labrum recover better. If you need hip arthroscopy and haven't had prior hip surgery, you may be able to join.
Boston, MassachusettsAges 18 years+ - NCT07568990Recruiting
Ureteral Access Sheaths for Kidney Stone Removal Surgery
This trial tests different types of tubes (called ureteral access sheaths) used during a minimally invasive kidney stone removal procedure called RIRS. The goal is to see which type works best and causes the least damage to your ureter (the tube that carries urine from your kidney).
Çorum, ÇorumAges 18–75 - NCT06559475Recruiting
Testing a new aspiration catheter for large vessel stroke
This trial tests a new catheter (Super-Bore 8/7F) to remove blood clots in people having a major stroke caused by a blocked large artery in the brain. The goal is to see if it is safe and effective at restoring blood flow when used within 24 hours of stroke symptoms starting.
Hefei, AnhuiAges 18 years+ - NCT06740097Recruiting
Testing tissue monitoring during brain tumor surgery
This study looks at a new way to check brain tumor tissue during surgery. If you are having surgery for an aggressive brain tumor, the doctors want to see if this monitoring technique is practical and helpful.
Kuopio, Northern SavoniaAges 18 years+ - NCT07515989Recruiting
Testing a nerve biopsy method to diagnose leprosy
This study tests a new way to diagnose leprosy by taking a tiny sample from a nerve under the skin using ultrasound guidance. The goal is to see if this method can accurately detect leprosy and help doctors know when treatment is working.
Brasília, Federal DistrictAges 14 years+ - 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 - 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+ - NCT02418832Recruiting
Sperm aspiration test for men with no sperm in semen
This study looks at a procedure that removes sperm directly from the testicles to help with IVF when a man has no sperm in his ejaculate. It may help couples try for pregnancy when standard semen samples don’t contain sperm.
JerusalemAges 16–80 - 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+ - NCT07255950Recruiting
Comparing lung biopsy methods for suspected lung cancer
This study compares two ways of doing a lung biopsy with a needle guided by ultrasound. It aims to see which method gives better samples for diagnosing lung cancer.
Yogyakarta, Special Region of YogyakartaAges 18 years+ - NCT07242729Recruiting
Compare two treatments for chronic heel pain from plantar fasciitis
This study compares two treatments—bone marrow aspirate and platelet-rich fibrin—to see which works better for long-lasting heel pain caused by plantar fasciitis. It may help if your pain has not improved with standard treatments like stretching or physical therapy.

Common questions
- Are there clinical trials for aspiration?
- Yes. Clin2 currently lists 264 recruiting aspiration 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 aspiration 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 aspiration 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.
