Mobile, AlabamaAges 18 years+ - NCT06045416Recruiting
Borrelia (Lyme) blood test study
This trial is testing a new blood test to help diagnose Lyme disease (borrelia infection) in children. If you are at the emergency room with symptoms that might be Lyme disease and you have a healthy immune system, you might be able to join.
ZurichAges 1 month–17 years - NCT06852352Recruiting
Modified brain lymph surgery for Alzheimer's or Parkinson's
This study tests a new, less invasive surgery to improve lymph drainage from the brain. It may help clear harmful proteins linked to Alzheimer's or Parkinson's disease.
Hangzhou, ZhejiangAges 50–80 - NCT06965062Recruiting
Neck surgery for Alzheimer's: a first test
This study tests a new surgery called cervical lymphatic bypass to see if it can help people with Alzheimer's disease. The surgery creates a new connection in the neck to improve drainage of waste from the brain, which may slow memory loss.
SingaporeAges 50–80 - NCT06530732RecruitingPhase 3
Neck drainage surgery for Alzheimer's disease
This study tests a new surgical treatment for Alzheimer's disease. The surgery aims to improve drainage in the neck to help clear waste from the brain. This is a first-of-its-kind pilot study to see if it is safe and might help thinking and memory.
Hangzhou, ZhejiangAges Any age - NCT07335341Recruiting
Liberant thrombectomy system case survey
This survey collects feedback from doctors who used the Liberant system to remove blood clots. The results help understand how well the device works in real-life procedures.
Washington D.C., District of ColumbiaAges 22 years+ - NCT07760363Recruiting
Foot exercise device for leg swelling
This study tests if using a foot pedal device while lying down can help reduce leg swelling in the hospital. It aims to see if this simple exercise can improve comfort and outcomes for people with fluid buildup.
Tulsa, OklahomaAges 18 years+ - NCT02219984Recruiting
Survey of adults taking blood thinners in a patient registry
This study builds a registry by asking adults who take blood thinners (anticoagulants) about their experiences. It may help improve care by learning how these medicines are used in real life.
Bologna, BOAges 18 years+ - NCT02280733Recruiting
Chronic wound registry for real-world care documentation
This study is a real-world registry that collects information about chronic wounds and ulcers as they’re treated in everyday settings. It may help improve how care is tracked and supported, even if you don’t get a new medicine from the study.
The Woodlands, TexasAges Any age - NCT06711120Recruiting
Comparing two treatments for varicose veins in the lower legs
This study compares two minimally invasive treatments (radiofrequency ablation and microwave ablation) for varicose veins in the small saphenous vein. If your varicose veins cause symptoms like pain, swelling, or heaviness, this trial may help determine which treatment works better.
ChengduAges 18–90 - NCT04536220Recruiting
Blood-based tests to help diagnose pancreatic cancer
This study uses blood taken from a vein to build and check diagnostic models for pancreatic cancer. It may help doctors identify pancreatic cancer more accurately in people who have a suspected mass on imaging.

Common questions
- Are there clinical trials for venous disease?
- Yes. Clin2 currently lists 59 recruiting venous disease 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 venous disease 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 venous disease 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.
