Recruiting studies
- 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.
Arlington Heights, IllinoisAges 18 years+ - NCT05030337Recruiting
Closed-loop oxygen control for very preterm babies on ventilators
This trial tests a computer-guided (“closed-loop”) oxygen control system for very preterm babies who need breathing support. It aims to keep oxygen levels safer and more consistent than standard care.
LondonAges Any age - NCT05120492Recruiting
Program for severe knee arthritis and extreme weight
This feasibility study tests a practical approach to help people with very severe knee arthritis and very high body weight. It aims to find an effective and safe way to manage both conditions together in real-world care.
Halifax, Nova ScotiaAges 18–65 - NCT05242835Recruiting
Study for weight regain after sleeve stomach surgery
This trial studies a specific type of metabolic (weight-related) surgery for people whose sleeve gastrectomy did not lead to enough weight loss or has caused significant weight regain. It may help improve long-term weight and related health problems.
Québec, QuebecAges 18–60 - NCT05264051Recruiting
MRI scan to predict outcomes in liver disease
This study looks at MRI images taken as part of routine care to see if they can help predict future health problems in people with liver disease. If you already have an MRI scheduled for clinical reasons, this may help doctors better estimate risk over time.
Chicago, IllinoisAges 18 years+ - NCT05305313RecruitingPhase 4
Testing a new propofol dosing method for higher BMI surgeries
This trial studies whether adjusting how propofol (an anesthesia medicine) is dosed based on total body weight improves anesthesia delivery during longer surgeries. It mainly targets people with a higher body mass index having surgery that lasts over an hour.
New Delhi, National Capital Territory of DelhiAges 18–65 - NCT05404061Recruiting
Study for people who don’t lose weight after bariatric surgery
This study looks at people who have had bariatric surgery but still struggle to lose weight (or lose it poorly). It aims to better understand how to help “poor responders” and what might be interfering with weight-loss results.
LondonAges 18–70 - NCT05440331Recruiting
Study of safer handoffs during major surgery in operating rooms
This trial looks at how well information is passed (a “handoff”) between anesthesia team members during major surgery. The goal is to improve safety by reducing preventable mistakes around the time patients move from one caregiver to another.
Boulogne-BillancourtAges 18 years+ - NCT05521776Recruiting
Early pregnancy screening to reduce complications after high blood pressure
This trial studies whether extra screening in the first trimester for preeclampsia (dangerous blood pressure problems in pregnancy) can reduce health problems for both the mother and baby. You may be offered a screening plan that helps identify risk earlier so care can be adjusted.
AngersAges 18 years+ - NCT05554016Recruiting
Ultra-processed food study in kids with obesity
This study looks at how eating ultra-processed foods affects metabolism and body weight in children and teens with obesity, and compares them with healthy peers. Your participation may help scientists understand whether diet choices contribute to weight and metabolic problems.
NaplesAges 6–18 - NCT05554224Recruiting
Personalized treatment based on obesity-related fatty liver tests
This study uses multiple types of health data (“multi-omics”) to help choose a personalized treatment plan for people with obesity-related fatty liver disease. It may help match treatment to your biology to improve outcomes.
Reus, TarragonaAges 18 years+ - NCT05558501RecruitingPhase 1/Phase 2
Intermittent low-oxygen therapy for sleep apnea and health risks
This early-stage study tests a treatment that briefly reduces oxygen during sleep to improve “plasticity,” with the goal of helping people with obstructive or mixed sleep apnea. It also looks at related conditions like high blood pressure and pre-diabetes or cholesterol problems, especially in people who haven’t tried CPAP yet.
Detroit, MichiganAges 30–60 - NCT05618054Recruiting
Explaining nerve signals in teens with POTS
This study looks at how a specific brain–vagus nerve connection works in people with POTS and tries to understand what happens over time. It may help researchers better explain symptoms and other health problems that can occur with POTS.
Richmond, VirginiaAges 12–21 - NCT05698966Recruiting
Low-dose steroid shot to help late preterm baby lungs
This study tests whether a low dose of a steroid medicine given to pregnant people late in pregnancy can help a baby’s lungs if delivery happens early. If you’re due for late-preterm delivery soon, the trial may help reduce breathing problems in the newborn.
AfulaAges 18–45 - NCT05711758Recruiting
Endoscopic stomach muscle cut for weight loss
This trial tests whether an endoscopic procedure that cuts a stomach outlet muscle can help with weight loss and be safe. You would be screened to make sure you don’t have certain stomach, heart/lung, or pregnancy-related conditions that could make the procedure unsafe.
Boston, MassachusettsAges 18–70 - NCT05726786RecruitingPhase 3
Immunonutrition before bladder removal surgery
This study tests whether a special nutrition drink given before open bladder surgery can reduce complications and improve the body’s immune response after surgery. It’s for adults having bladder removal and is compared against standard care.
Lausanne, Canton of VaudAges 18 years+ - NCT05759078RecruitingPhase 4
IV iron treatment after a heart attack for low-iron patients
This trial tests whether giving IV ferric carboxymaltose can lower the risk of death and heart complications after a recent heart attack, and improve quality of life. It is for adults with low iron levels and specific heart/health risk factors identified soon after their heart attack.
Bydgoszcz, Kuyavian-Pomeranian VoivodeshipAges 18–90 - NCT05777928Recruiting
Tests satiety changes after bariatric surgery revision
This study looks at how feelings of fullness (satiety) change in people getting bariatric surgery—either a sleeve gastrectomy or a revision procedure. It may help improve how well weight-loss stays on track after surgery.
MilanAges 18–65 - NCT05783466Recruiting
Testing how dairy affects heart risk in people with high weight
This study looks at whether eating more dairy (from cow’s milk) changes markers linked to heart and metabolic risk in adults with higher body weight. It mainly aims to understand how diet affects the body’s metabolism and related risk factors.
Pierre-BéniteAges 18–70 - NCT05788120Recruiting
Study heart rhythm problems in adults on VA ECMO
This study looks at how often abnormal heart rhythms happen and how serious they are in adults who are supported with VA ECMO for severe heart failure. It mainly involves using medical information, aiming to better understand complications in this critical situation.

Testing a gut bacteria supplement side effects during prostate hormone therapy
This early-phase study looks at how changing gut bacteria (especially Akkermansia) affects metabolic side effects in men starting prostate hormone therapy (ADT). It may help researchers understand how to reduce or manage side effects for people on ADT.
London, OntarioAges 18 years+ - NCT05816798RecruitingPhase 2/Phase 3
Laser treatment to reduce chronic knee pain before weight-surgery
This trial tests whether photobiomodulation (a type of laser/light therapy) can reduce chronic pain in both knees for people preparing for bariatric (weight-loss) surgery. If you have knee pain that limits daily life, the treatment may help you feel better while you’re in the pre-surgery rehabilitation period.

Common questions
- Are there clinical trials for morbidity?
- Yes. Clin2 currently lists 217 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.
