Recruiting studies
- NCT05479448Recruiting
Tracking what predicts response in new PMR or GCA
This study looks at people newly diagnosed with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) and uses their health and treatment information to learn what predicts how well treatment works. It may help your care in the future by improving which patients respond best and how.

Tracking factor X deficiency to improve patient care
This study collects health information and blood samples from people with factor X deficiency (a rare bleeding disorder) and their close family members. The goal is to learn more about how the condition progresses over time, which could lead to better treatment and management.
FlorenceAges Any age - NCT05081115Recruiting
Stress echo imaging for people with heart valve or muscle issues
This trial studies a stress echocardiogram (an ultrasound of the heart during stress) to better understand and improve future heart imaging. It may help by comparing how well the test works for different heart conditions.
BeneventoAges 18–75 - NCT02301663Recruiting
Stress test study of heart blood-flow issues in adults
This study tests a new kind of stress test to understand how small blood-vessel heart problems relate to heart relaxation problems in people with angina (chest pain) but no blocked arteries. It may help doctors learn better ways to diagnose and guide treatment for these conditions.
Los Angeles, CaliforniaAges 18–60 - NCT05620290RecruitingPhase 1
MR-guided ultrasound plus radiation to help skin cancer respond
This Phase 1 study tests a new way to make radiation work better using MRI-guided focused ultrasound. It focuses on improving treatment for malignant melanoma and other skin cancers, while checking safety and how patients experience treatment.
Toronto, OntarioAges 18 years+ - NCT06397677Recruiting
Study of Progressive RA Interstitial Lung Disease
This study is looking at people with rheumatoid arthritis (RA) who also have interstitial lung disease (ILD), a condition that causes scarring in the lungs. It aims to understand how the disease changes over time by using imaging and blood tests, without providing any new treatments right now.
San Francisco, CaliforniaAges 18–90 - NCT07822737Recruiting
Using CT scans to find high-risk heart plaque
This study uses a special CT scan to look at the inside of your heart arteries and find any high-risk fatty deposits (plaque) that might cause problems later. It aims to see if this scan can predict future heart events, so you and your doctor can make better treatment choices.
Beijing, ChinaAges 18 years+ - NCT07770126Recruiting
Stomach bacteria study for gastric conditions and precancer
This study looks for certain stomach bacteria (other than the common H. pylori) that might be linked to stomach diseases or early signs of cancer. If you have a stomach condition, your participation could help doctors understand these bacteria better.
EdegemAges 18 years+ - NCT07749924Recruiting
Watchful waiting vs. bladder chemotherapy for intermediate-risk bladder cancer
This study compares two approaches for people with intermediate-risk bladder cancer whose urine shows no signs of cancer after surgery. One group will be watched closely (active surveillance), while the other will receive chemotherapy directly into the bladder (intravesical chemotherapy). The goal is to see if surveillance alone can prevent unnecessary treatment while keeping the cancer controlled.
DaqingAges 18 years+ - NCT06185972RecruitingPhase 2
MRI-guided ultrasound radiation for breast and chest cancer
This trial tests a new way to give radiation therapy using MRI imaging and ultrasound to make the radiation more targeted and potentially safer. If you have chest-wall or breast cancer and are already scheduled for radiation, this approach might offer a more precise treatment option.
Toronto, OntarioAges 18 years+ - NCT06633601RecruitingPhase 1
Ultrasound and microbubbles with radiation for breast cancer
This trial tests a new way to combine radiation therapy with ultrasound and tiny bubbles to treat breast cancer that has spread to the chest wall or is advanced. It aims to make radiation more effective and safer.
Toronto, OntarioAges 18 years+ - NCT07714499Recruiting
Energy use in healthy people vs. those with intestinal failure
This study looks at how the body uses energy (calories) in people with intestinal failure compared to healthy controls. The results may help improve nutritional care.
LjubljanaAges 18–65 - NCT07610226Recruiting
Cataract Surgery Lens for Prior Myopic Eye Surgery
This study tests a special intraocular lens (an artificial lens implanted during cataract surgery) designed for patients who had prior myopic refractive surgery (LASIK or PRK to correct nearsightedness). The goal is to achieve the best possible vision correction after cataract removal.
Greensboro, North CarolinaAges 18 years+ - NCT07586046RecruitingPhase 2
Radiation treatment for liver tumors
This study tests a higher dose of radiation delivered directly to liver tumors through small beads. It aims to improve tumor control while keeping side effects manageable for people whose liver cancer is not removable by surgery.
Chicago, IllinoisAges 18 years+ - NCT06724536Recruiting
Study of gut bacteria and TKIs in chronic myeloid leukemia
This trial looks at how gut bacteria affect the way chronic myeloid leukemia (CML) patients respond to tyrosine kinase inhibitor (TKI) medications. It may help doctors understand why some people have better outcomes than others.
TorinoAges 18 years+ - NCT07572630Enrolling by invitation
How your brain processes visual information and attention
This research study examines how your brain focuses on and processes visual details. Participants will complete visual tasks while we monitor brain activity using safe imaging technology, helping us understand how attention shapes what we see.
Santa Barbara, CaliforniaAges 18–55 - NCT07574736Recruiting
Finding the right way to place a heart ultrasound probe
This study helps doctors find the easiest way to correctly position a small ultrasound probe in your food pipe to get better pictures of your heart. If you're in the ICU and need this type of heart imaging, this research could improve how safely and quickly the procedure is done.
Merano, BZAges Any age - NCT07555574Recruiting
New imaging technology to see retinal structures clearly
This research study tests a new camera technology that takes detailed pictures of the back of your eye (retina) to better understand eye diseases. Researchers want to compare images from people with eye conditions like diabetes-related eye disease, glaucoma, or age-related macular degeneration with healthy volunteers to see how the new imaging works.
Melbourne, VictoriaAges 18 years+ - NCT07516379Recruiting
Understanding Lung Rejection After Transplant
This study follows people with serious lung disease before and after lung transplant to understand how rejection happens and what warning signs to watch for. By studying your blood, tissue samples, and imaging, researchers hope to better predict and prevent transplant rejection.
Bethesda, MarylandAges 18–75 - NCT07523542RecruitingPhase 1/Phase 2
CAR-T Cell Therapy for Treatment-Resistant Lupus
This study tests a new type of immune cell therapy (CAR-T cells) designed to target and reduce the immune cells driving lupus in patients whose disease hasn't responded to standard treatments. Researchers will first identify which specific immune cells are causing your lupus, then engineer your own immune cells to fight them.
Shenzhen, GuangdongAges 18–70 - NCT07517393Recruiting
Creating a Digital Lung Model Using AI and CT Scans
This study collects information from your chest CT scans and medical history to build an artificial intelligence model of how your lungs work. This 'digital twin' may help doctors better understand and predict lung health in the future.

- How do I know if I qualify for a Definity trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Definity an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Definity or a specific trial is right for you.
