Screening for Lymphedema in Breast Cancer Targeted Therapy
This study is looking at whether targeted therapy for breast cancer changes the risk of arm swelling (lymphedema). It is a screening trial that uses a machine to measure arm size and check for any swelling early on.
Boston, MassachusettsAges 18–80 - NCT07536308RecruitingPhase 1
Nasal COVID-19 booster vaccine safety trial
This trial tests a new nasal spray COVID-19 booster vaccine. It aims to see if the vaccine is safe and produces a strong immune response when given through the nose and inhaled, in people who have already been vaccinated.
Decatur, GeorgiaAges 18–64 - NCT07417605Recruiting
Using a new PET scan to tell cancer from inflammation after radiation
This study uses a special PET scan to tell the difference between leftover cancer and inflammation caused by radiation in people treated for head and neck cancer. It may help doctors know if more treatment is needed.
BrestAges 18 years+ - NCT05829044Recruiting
How light exposure affects sleep and body clock by sex and age
This study looks at how non-visual light (light that isn’t just for seeing) affects your sleep timing and circadian rhythms, and whether the effects differ by sex and age. It may help researchers design better light-based or sleep-support strategies in the future.
Boston, MassachusettsAges 18–85 - NCT05943535RecruitingPhase 3
Breathing treprostinil to slow progressive lung scarring
This Phase 3 trial tests whether inhaled treprostinil can slow progression of lung fibrosis (scarring) that keeps getting worse despite standard care. It also looks at safety, because inhaled medicine can cause side effects and needs careful monitoring.
Birmingham, AlabamaAges 18 years+ - NCT07355192Recruiting
Group singing for heart health
This study tests whether singing in a group can improve heart health in people with a history of coronary artery disease. If you join, you'll sing with others and see if it helps your heart function.

This study looks at how metabolism and inflammation relate to diabetes risk in teenagers. It may help researchers understand why some teens develop type 2 diabetes.
Ann Arbor, MichiganAges 14–18 - NCT07611968Recruiting
Physician-Modified Stent Grafts for Aortic Aneurysms
This trial tests a custom-made stent graft (a tube that reinforces the aorta from inside) for patients with large aortic aneurysms who may be too sick for traditional open surgery. The goal is to prevent rupture and complications while avoiding major surgery.
Jacksonville, FloridaAges 50 years+ - NCT07314736Recruiting
Study on values and ethics for ultra-rare diseases
This study aims to understand the perspectives of parents, caregivers, family members, and professionals involved with children who have ultra-rare genetic disorders. It uses interviews or focus groups to explore ethical and value-based questions.
Memphis, TennesseeAges Any age - NCT04936854RecruitingPhase 2
Sirolimus or steroid drops for active Graves eye disease
This Phase 2 study compares sirolimus versus corticosteroids to treat active thyroid eye disease. It aims to see which treatment works better to calm eye inflammation and improve symptoms, without needing urgent eye surgery.
Bergen, HordalandAges 18–80 - NCT04937868Recruiting
Guiding CT scans for belly and pelvis injuries after blunt trauma
This study looks at how to make a better decision tool for when to order a CT scan of the belly and pelvis after a blunt injury in the emergency department. It aims to help clinicians choose the right patients for imaging during the first evaluation.
Los Angeles, CaliforniaAges Any age - NCT04939571Recruiting
Registry for babies with retinopathy of prematurity
This study is a European registry that collects medical information (stored electronically) about babies who have retinopathy of prematurity (ROP) severe enough to need treatment. It may help doctors understand outcomes and improve care by tracking real-world results.
SalzburgAges Any age - NCT04951622RecruitingPhase 3
Testing nipocalimab for adults with generalized myasthenia gravis
This Phase 3 study tests nipocalimab, a medication given by infusion (and in some groups by injections under the skin), to improve symptoms in adults with generalized myasthenia gravis (MG). It may help reduce weakness in daily activities, especially if you meet specific symptom and safety criteria.
Paradise Valley, ArizonaAges 18 years+ - NCT04952480RecruitingPhase 2
Adaptive chest radiation for newly diagnosed small cell lung cancer
This study tests a customized (“adaptive”) way to give radiation to the chest for newly diagnosed small cell lung cancer. It aims to improve how well treatment targets the tumor while safely adjusting to tumor changes during therapy.
Edmonton, AlbertaAges 18 years+ - NCT04952870Recruiting
Study breathing treatment and early immunity in newborns after COVID
This study looks at how newborns’ bodies are affected by COVID-19 around birth and whether a breathing support treatment (inhaled nitric oxide) changes outcomes. It also compares COVID-exposed babies and a similar group of babies without COVID who are not receiving the breathing treatment.
LilleAges Up to 3 months - NCT04954599RecruitingPhase 1/Phase 2
CP-506 for hard-to-treat cancers with DNA repair defects
This Phase 1/2 study tests CP-506 in people with advanced solid tumors that have specific DNA repair problems (homologous recombination or Fanconi anemia-related defects). It may be used alone or combined with carboplatin or an immune therapy, aiming to shrink tumors or improve control when standard options are limited.
BrusselsAges 18 years+ - NCT04954820RecruitingPhase 2
Second round Lutathera for intestinal NET after regrowth
This Phase 2 study looks at whether giving Lutathera again (a second round) can control an intestinal neuroendocrine tumor (NET) that came back or progressed after the first treatment. It mainly targets adults whose scan shows tumors still take up the right “target” signal and who previously benefited for at least 12 months.
AngersAges 18 years+ - NCT04957095Recruiting
Testing brain wiring signals during planned deep brain stimulation
This study looks at how brain networks work during a procedure used to treat movement symptoms in Parkinson’s disease. It may help researchers better understand the brain signals involved, which could improve future deep brain stimulation planning.
Dallas, TexasAges 18–89 - NCT04964310Recruiting
Testing genetic risk for acetaminophen-related liver injury
This study looks at whether certain genes can predict who is more likely to get liver injury after taking acetaminophen (also found in some cold/flu medicines). By comparing people who were affected with people who were not, it may help doctors identify higher-risk patients in the future.
Nanjing, JiangsuAges 14 years+ - NCT04966351Recruiting

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.
