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.

Fecal transplant study for hard-to-treat C. difficile diarrhea
This Phase 1 study tests defined fecal microbiota (healthy gut bacteria) given to people with C. difficile diarrhea that didn’t go away or came back soon after antibiotics. It may help by restoring a healthier balance of gut bacteria so the infection can stop recurring.
Houston, TexasAges 18 years+ - NCT07190456Recruiting
Study on fear of movement after ACL surgery
This study looks at different types of fear people might feel after ACL surgery, especially when doing jumping tasks. It aims to help understand these fears better so rehab can be improved.
Caparica, AlmadaAges 18–35 - 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 - NCT07004751Recruiting
Finding the cause of fever in Nepal
This study is trying to find the cause of fevers that last from 3 to 21 days in people who are admitted to the hospital. It may help doctors better understand and treat fevers in Nepal.
Lalitpur, BagmatiAges 16 years+ - NCT06581887Recruiting
Measuring behavior and emotions in Duchenne and Becker muscular dystrophy
This study looks at how to measure behavioral and emotional challenges in boys with Duchenne or Becker muscular dystrophy, and in boys without the condition. It aims to find better ways to assess these issues, which could help improve care and treatments.
LondonAges 7–17 - NCT06782776Recruiting
Doppler ultrasound for twin pregnancy risk
This study uses a special ultrasound technique called Doppler echoflowmetry to measure blood flow in mothers pregnant with twins. The goal is to find early signs that might predict complications, so doctors can offer better care.
Bologna, BolognaAges 18–44 - NCT07317193Recruiting
Genetic causes of adult bile duct disease
This study looks for new genes that might cause abnormal liver test results or specific bile duct diseases in adults, when standard testing hasn't found a clear cause. It also uses healthy blood donors as a comparison group.
Milan, MilanoAges 18–65 - 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 - 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+ - 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.

Common questions
- Are there clinical trials studying Definity?
- Yes. Clin2 currently lists 76 recruiting studies that include Definity, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- 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.
