Recruiting studies
- NCT03554902Recruiting
Endoscopic procedure for gastric tubulization
This trial is for people who are already planned to have a specific stomach (gastric) procedure using an endoscope (a flexible camera). It mainly aims to study how this procedure is done and how patients do afterward.
StrasbourgAges 18–65 - NCT03868592Recruiting
Weight loss study in people with very high body weight
This trial looks at how to support long-term weight loss and improve how your body handles fat breakdown. It may help people who have severe obesity after bariatric (weight-loss) surgery, but it has several health and lifestyle limits.
Rochester, MinnesotaAges 18–65 - NCT03875625Recruiting
Tracking body fat and liver fat after weight-loss treatment
This study looks at how body fat and liver fat change after bariatric (weight-loss) surgery or a lifestyle program. You may join if you have overweight or obesity and can safely have MRI scans, so researchers can compare results between treatment approaches.
Hong Kong, ShatinAges 18–65 - NCT03919188Recruiting
Compare air versus skin-touch care for very preterm babies
This study looks at two ways of providing control or calming in incubators for very preterm babies (born before 32 weeks) to see how they affect growth and health problems. It may help caregivers learn which method supports safer, healthier development.
Amiens, PicardieAges Up to 1 day - NCT04020263RecruitingPhase 3
Levosimendan early treatment vs placebo for cardiogenic shock
This study tests whether giving levosimendan early (a heart-strengthening medicine) improves outcomes compared with placebo, on top of standard inotropic support, in people with cardiogenic shock. It mainly looks at whether patients have fewer serious complications or deaths.
Strasbourg, Bas-RhinAges 18 years+ - NCT04040413Recruiting
Database update for bariatric weight-loss surgery
This trial is a “database maintenance” study related to bariatric (weight-loss) surgery. It helps keep the records up to date and may support future care by organizing information about patients who get surgery.
Ramat GanAges Any age - 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 - 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 - 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 - 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 - NCT04626050Recruiting
PTSD and stress support study for healthcare workers
This study looks at psychological distress, including post-traumatic stress disorder (PTSD), in healthcare workers after work-related trauma. You may be eligible if you are an adult healthcare worker with PTSD (and otherwise stable) who can complete regular study check-ins.
New York, New YorkAges 18 years+ - 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+ - 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 - NCT04767490Recruiting
New weight-loss surgery method for eligible adults with obesity
This trial compares a new type of weight-loss surgery (single anastomosis) to the standard duodenal switch. It’s meant for adults with severe obesity and aims to see which operation is safer and works better for weight and health.
Québec, QuebecAges 18–60 - 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 - NCT04894838Recruiting
Testing a bypass revision surgery for weight regain
This study looks at whether a specific stomach bypass revision (a “distal gastric bypass”) can improve outcomes after Roux-en-Y gastric bypass when weight loss was not enough or weight was regained. You may be considered if you meet weight-loss goals criteria and can join follow-up and possibly surgery.
Arnhem, GelderlandAges 18–65 - NCT07698665Recruiting
Ketamine vs dexmedetomidine in scalp block for brain tumor surgery
This trial compares two medicines, ketamine and dexmedetomidine, added to a scalp nerve block during brain tumor removal surgery. The goal is to see which provides better pain control and recovery after surgery.
Cairo, GovernorateAges 20–60 - NCT07699666Recruiting
Cord clamping timing for preterm babies
This study compares waiting a bit before clamping the umbilical cord versus clamping it right away for babies born between 32 and 37 weeks of pregnancy. It helps determine which approach may be better for preterm infants.
Tunis, Tunis GovernorateAges birth+ - 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 - NCT05000996Recruiting

Nashville, TennesseeAges 21–65 - NCT05013944Recruiting
Join a patient registry to support future research
This trial is a “patient registry,” which collects health information over time to help researchers plan and run future studies. It may help by contributing your experience so new treatments can be tested more effectively.

Common questions
- Are there clinical trials for morbidity?
- Yes. Clin2 currently lists 218 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.
