NaplesAges 18 years+ - NCT05250375Recruiting
Study of mitochondrial muscle diseases over time
This natural history study follows children and adults with suspected or confirmed mitochondrial myopathy to better understand symptoms and how the condition changes. It may also include healthy participants to compare test results and improve future treatments.
Philadelphia, PennsylvaniaAges birth–100 years - NCT05254782Recruiting
Blood test after lung tumor surgery to find hidden disease
This study uses a special blood test to look for tiny traces of lung cancer after surgery. It aims to find “minimal residual disease,” meaning cancer cells that may still be hiding after your tumor is removed.
Toronto, OntarioAges 18 years+ - NCT05255302RecruitingPhase 2/Phase 3
Shorter immune maintenance for stage IV lung cancer after initial treatment
This trial tests whether giving immune therapy maintenance for a shorter time helps people with stage IV non-small cell lung cancer (NSCLC) who are doing well after initial chemo-immunotherapy. It aims to keep the cancer controlled while possibly reducing treatment exposure and side effects.
Aix-en-ProvenceAges 18–74 - NCT05257967Recruiting
Testing spinal fluid in EGFR-mutant lung cancer with brain covering spread
This trial looks at spinal fluid (also called CSF) in adults with EGFR-mutant lung cancer that has spread to the lining around the brain/spinal cord. The goal is to better understand the disease and what the spinal fluid tests may show to guide care.
Vancouver, British ColumbiaAges 18 years+ - NCT05258981Recruiting
MRI and testing study linking genes and thinking in adults
This study looks at how patterns on brain MRI scans and genes relate to thinking and test performance in adults. It may help researchers better understand long-term brain and cognitive outcomes and how they differ between people with specific early-life heart conditions and healthy controls.
Boston, MassachusettsAges 24–35 - NCT05258448Recruiting
Chemo-radiotherapy for advanced, non-surgical lung cancer
This trial studies treatment that combines chemotherapy and radiation for people with advanced lung cancer that cannot be removed with surgery. It may help improve cure chances for patients who can complete the study tests, including heart scans.
Odense CAges 18 years+ - NCT05260177Recruiting
40 Hz light therapy for mild to moderate Alzheimer’s
This study tests whether a non-invasive 40 Hz light therapy system can help people with early Alzheimer’s. You’ll likely use the device at home and wear a small activity monitor, while doing memory and thinking tests.
RoskildeAges 40 years+ - NCT05260671RecruitingPhase 2
Penpulimab plus cetuximab for advanced head and neck cancer
This trial studies penpulimab (an immune medicine) combined with cetuximab (an antibody drug) for recurrent or metastatic squamous cell head and neck cancer that cannot be treated with surgery or radiation. It aims to shrink tumors and improve survival in people whose tumor shows a specific immune marker (PD-L1).
Changchun, JilinAges 18–80 - NCT05261139RecruitingPhase 3
Trial for PF-07321332 for children at risk from COVID-19
This trial studies whether PF-07321332 (with ritonavir) helps children under 18 who have COVID-19 at home but are at high risk of severe illness. It looks at whether starting treatment early can reduce progression to worse disease.
Phoenix, ArizonaAges birth–17 years - NCT05262907Recruiting
Study of heart imaging in people with one pumping ventricle
This study uses routine heart scans (either echocardiogram or MRI) to better understand single-ventricle heart conditions. It may help improve how doctors evaluate and monitor your heart over time.
Durham, North CarolinaAges Any age - NCT05265299RecruitingPhase 3
Testing the right aspirin dose for COPD symptoms
This Phase 3 trial studies which aspirin dose works best in people with COPD, with the goal of improving disease control. You may be asked to take aspirin and be monitored for safety, especially bleeding risk and heart/brain history.
Baltimore, MarylandAges 40–80 - NCT05266222Recruiting
Collecting respiratory virus samples for a research library
This study collects samples from people who have or might have a cold/respiratory virus, then stores them for future research. It may help researchers better understand respiratory germs and develop better treatments.
Bethesda, MarylandAges 3 years+ - NCT05266872Recruiting
Earlier diagnosis and better treatment study for Parkinson’s
This study is looking to improve how Parkinson’s and related brain conditions are identified and treated sooner. You may be asked to share your health information and provide blood or other samples, and possibly have procedures like a spinal fluid test or a small skin sample.
LuxembourgAges 18 years+ - NCT05266976Recruiting
Exercise types and bone markers in healthy older veterans
This study compares different ways of exercising to see how they affect “bone-related” blood markers in older adults. It may help you and researchers understand which exercise patterns support healthy bones.
Aurora, ColoradoAges 60 years+ - NCT05270616Recruiting
Robotic or video-assisted lung surgery compared
This trial compares robotic surgery and video-assisted surgery for removing part of the lung (lobectomy or segmentectomy). It may help determine which approach is safer or works better for patients who can safely tolerate minimally invasive surgery.
Jinan, ShandongAges 18–85 - NCT05275608Recruiting
Low-carb diet effects in people with metabolic syndrome
This trial studies whether a very low-calorie, low-carb diet (VLCKD) can improve metabolic health in adults with metabolic syndrome, fatty liver, and type 2 diabetes. It may help lower blood sugar and improve related health markers if you fit their specific diabetes and liver/kidney criteria.
Novara, ItalyAges 25–65 - NCT05274854Recruiting
Practice change study for severe unexplained gut symptoms
This study looks at a new approach to care for adults with severe, long-lasting stomach or bowel symptoms when no clear cause has been found. It may help you get more coordinated support through an integrated care clinic.
Woolloongabba, QueenslandAges 18–90 - NCT05278052RecruitingPhase 3
Maintenance therapy alone versus radiation plus maintenance for lung cancer
This trial compares standard maintenance treatment versus adding focused radiation to remaining limited (oligometastatic) spots in the body after initial chemotherapy. It aims to see whether treating those limited spots with radiation can improve outcomes without unacceptable side effects.
Mumbai, MaharashtraAges 18–99 - NCT05277844RecruitingPhase 2
Radiation plus targeted pill vs pill alone for EGFR/ALK-NSCLC
This study tests whether adding focused radiation to a targeted cancer pill works better than the pill by itself. It is for people with advanced non-small cell lung cancer (NSCLC) whose tumor has an EGFR or ALK/ROS driver mutation and who have not gotten worse after starting the targeted pill.
Mumbai, MaharashtraAges 18–99 - NCT05277272Recruiting
Registry study for children with HLH
This study is a disease registry that collects medical information from children who have hemophagocytic lymphohistiocytosis (HLH) or are suspected to have it. It helps doctors better understand HLH and how it affects patients over time.
Cincinnati, OhioAges Any age - NCT05279040Recruiting
Trikafta plus exercise program for adults with cystic fibrosis
This study tests how starting Trikafta affects exercise ability and breathing in adults with cystic fibrosis. You may be asked to do supervised breathing and exercise tests to see if Trikafta helps your lung function and stamina.

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.
