LondonAges Any age - NCT04942041Recruiting
Thrombectomy for large stroke blockages at low-volume centers
This study tests whether using a procedure called mechanical thrombectomy at smaller stroke centers can improve outcomes after a large-vessel stroke. It may help people who have a major artery blockage get timely treatment, with measured effects on complications and survival.
Kristiansand, AgderAges 18–100 - NCT04945473Recruiting
Testing weight-loss surgery follow-up and gastric “recalibration”
This trial studies what happens after a weight-loss procedure called endoscopic sleeve gastroplasty (ESG) and whether a “recalibration” approach can improve results. You may be considered if you have long-term obesity that did not improve with lifestyle/medical treatment.
StrasbourgAges 18–75 - NCT04841057Enrolling by invitation
Study of blood and stool changes after weight-loss surgery
This study looks at how your body’s metabolism changes after a specific weight-loss surgery (gastric bypass). It may help researchers better understand what to expect and how to tailor care, while requiring blood draws and stool samples before and after surgery.
Columbia, MissouriAges 18–80 - NCT04852198Recruiting
Compare two weight-loss surgeries in people with high BMI
This study compares two types of bariatric surgery to see which one works as well as the other for weight loss and health. You may be a candidate if you have a high BMI and specific related health problems, and if certain stomach and digestive issues don’t apply to you.
Almere StadAges 18–65 - NCT04766801Recruiting
Survey for teens seeking weight-loss surgery
This study is a health and survey project for teenagers who are considering bariatric (weight-loss) surgery. It aims to better understand the teen experience and support needs before surgery.
Angers, Maine Et LoireAges 14–20 - NCT04663893Recruiting
Study of fractures around implants after injury or surgery
This study looks at how often certain shoulder, elbow, hip, and knee fractures happen around orthopedic hardware (implants), and how they affect recovery and outcomes. Results may help doctors choose better treatment and predict risks for patients with these fracture types.
BarcelonaAges 18 years+ - NCT04679584Recruiting
Study of long-term effects after COVID-19 infection
This study looks at how COVID-19 can affect health and quality of life over the long term. It may help researchers understand symptoms that can last and what changes people experience after recovery.
Würzburg, BavariaAges 18 years+ - NCT04422405Recruiting
One-anastomosis stomach bypass study for reflux and stomach changes
This study looks at how a one-anastomosis gastric bypass changes how your stomach and esophagus work, especially relating to acid reflux. You may be offered the planned surgery if you fit the weight and heartburn/reflux-related conditions, and the team will measure changes before and after.
Schlieren, Canton of ZurichAges 18–65 - NCT04405700Recruiting
Tracking birth outcomes and birth defects after delivery
This study follows pregnant people and their babies to better measure adverse outcomes and possible congenital (from birth) conditions. It may help improve how birth risks and birth defects are identified and recorded at the clinic.
EldoretAges Any age - NCT04326192Recruiting
Spinal cord stimulation to reduce stubborn back and leg pain
This trial tests whether spinal cord stimulation (a treatment where a device sends mild signals to the spinal cord) can improve persistent nerve-type back and leg pain. It is mainly for adults who are already planning to try spinal cord stimulation but have not tried it before.
Portland, OregonAges 21–70 - NCT04232566Recruiting
Study links in obesity surgery and liver scarring
This study looks at how the immune system relates to liver scarring in people with obesity who are getting gastric bypass surgery. If you qualify, you may help doctors better understand liver disease and who is at higher risk.
Scottsdale, ArizonaAges 30–70 - NCT04040413Recruiting
Database update for bariatric weight-loss surgery

Common questions
- Are there clinical trials for morbidity?
- Yes. Clin2 currently lists 208 recruiting morbidity 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 morbidity 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 morbidity 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.
