Recruiting studies
- NCT05521503Recruiting
Collecting heart tissue samples for a shared research database
This trial builds a database by collecting and storing biopsy or biopsy-related samples from adults being evaluated for certain heart conditions. It may help researchers study heart disease and amyloidosis by making past tissue samples easier to access for future research.
Lexington, KentuckyAges 18 years+ - NCT05521789RecruitingPhase 4
Erector spinae block for thoracic surgery pain relief
This trial tests a specific pain-block injection (called an erector spinae block) to help with pain during thoracic surgery that removes part of the lung. You might benefit from better pain control and possibly fewer pain medicines, depending on what the study finds.
Washington D.C., District of ColumbiaAges 18–90 - NCT05522218Recruiting
Eluvia stent for blocked or narrowed leg artery
This trial looks at using an Eluvia drug-coated stent to treat a blocked or severely narrowed artery in the upper leg/knee area. It may help improve blood flow to the leg, and the study will follow patients to see how they do over time.
Hangzhou, ZhejiangAges Any age - NCT05525039Recruiting

This trial studies whether a vibration treatment combined with an HMB supplement can improve weak muscle quality and reduce early nerve-to-muscle connection problems. It is mainly for older adults who already have signs of low muscle strength or function.
Hong KongAges 60 years+ - NCT05525312Recruiting
Two breathing strategies during lung surgery for lung cancer
This trial compares two ways of managing breathing while you have surgery to remove lung cancer. It may help doctors figure out which strategy is safer and works better during the operation.
MontpellierAges 18 years+ - NCT05526963Recruiting
Help reduce unnecessary medicines in older adults
This study aims to reduce the number of long-term medicines older adults take when they have multiple chronic conditions. It may help by simplifying medicine routines and improving safety and care coordination with a family doctor.
Halle, Saxony-AnhaltAges 70 years+ - NCT05528744Recruiting
Study genes and symptoms in ANKRD17-related CAGS
This study looks at how a specific gene change in ANKRD17 relates to the symptoms, brain/scan findings, and brain-cells in people with Chopra-Amiel-Gordon syndrome (CAGS). It may help families understand the condition better and connect gene results to what is seen clinically.
Boston, MassachusettsAges Any age - NCT05529459Recruiting
Guidance method for opening heart blockages with stents
This study compares two ways of deciding how completely to open blocked heart arteries using drug-eluting stents. It aims to see which guidance approach improves results and safety for people with coronary artery disease who need a PCI (heart catheter procedure).
AnyangAges 19 years+ - NCT05530408Recruiting
Pulmonary scan imaging registry and blood sample collection
This trial builds a research database from people who take lung scans like pulmonary MRI or CT at the University of Kansas Medical Center. It may help researchers better understand lung disease and improve future diagnosis or treatment.
Kansas City, KansasAges 18 years+ - NCT05531773Recruiting
Study for ongoing symptoms after COVID-19
This trial studies people with mild to moderate COVID-19 symptoms to better understand and help “post-COVID” condition (ongoing effects after infection). You may be eligible if you’re an adult with a recent confirmed COVID-19 test and you agreed to take part.
DüsseldorfAges 18 years+ - NCT05532631Recruiting
Compare stent procedure versus bypass surgery for weak heart
This study compares two ways to improve blood flow to the heart—using stents through a catheter or bypass surgery—in people with heart muscle weakness and blockages in more than one coronary artery. It may help identify which approach leads to better outcomes over at least two years.
Créteil, Val De MarneAges 18 years+ - NCT05536102RecruitingPhase 2
Surgery-plus chemo and immunotherapy for HER2-negative gastric cancer
This Phase 2 trial studies whether adding two medicines (XELOX and tislelizumab) and another chemotherapy drug (PLD) around the time of surgery works better and is safe for people with stage III gastric (stomach) cancer. It is designed for tumors that are HER2-negative and PD-1/L1 positive.
ShanghaiAges 18–75 - NCT05543681RecruitingPhase 2
Study drug for agitation in Alzheimer’s dementia with caregiver support
This Phase 2 trial tests a study medicine to reduce “agitation” behaviors in people with Alzheimer’s dementia. You and your caregiver would complete required assessments and may need genetic and blood testing to check how the body handles the drug.
Maitland, FloridaAges 60 years+ - NCT05543083Recruiting
Therapy plus exercise for teens at risk of type 2 diabetes
This trial tests whether a combination of coaching (cognitive-behavioral therapy) and exercise can improve mood and help teens who are at higher risk for type 2 diabetes. It may be especially helpful if you’re dealing with depression symptoms and a family history of type 2 diabetes.
Aurora, ColoradoAges 12–17 - NCT05544968RecruitingPhase 1
CD30-targeted cell treatment for hard-to-treat blood cancers
This Phase 1 trial studies an experimental treatment that targets a marker called CD30 on cancer cells. It is for adults with certain relapsed or refractory CD30-positive blood cancers to see how well the treatment works and what side effects it causes.
Milwaukee, WisconsinAges 18 years+ - NCT05545306Recruiting
Study tests how extra calories change your daily energy use
This study looks at how eating more calories affects your body’s natural heat production and total energy use over a full day. It may help researchers better understand how the body manages weight and energy.
Phoenix, ArizonaAges 18–60 - NCT05544864Recruiting
Stent or balloon treatment guided by heart scar pattern
This study looks at how to treat blocked heart arteries that have narrowed again after a prior drug-eluting stent. It compares using another drug-eluting stent versus a drug-coated balloon, chosen based on an imaging scan inside the artery (OCT), to reduce repeat narrowing.
Frankfurt am Main, HesseAges 18 years+ - NCT05545865Recruiting
Test how grape-based drinks affect blood flow response
This study tests whether a grape product (“Chardonnay Marc”) can change how your blood vessels respond to stress, measured with a finger sensor. It may help researchers understand how diet influences circulation in people with a low baseline blood-flow response.
Davis, CaliforniaAges 30–50 - NCT05546086Recruiting

Patient-guided blood pressure control in chronic kidney disease
This Phase 3 study tests whether a patient-driven plan for managing blood pressure can better control hypertension in people with chronic kidney disease (CKD). The goal is to see if this approach is safe and helps prevent health problems related to high blood pressure.
Iowa City, IowaAges 18 years+ - NCT05552352Recruiting
VR training to help people prepare for aortic valve procedure

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 recruiting general population (no specific condition or 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 general population (no specific condition or 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 general population (no specific condition or 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.
