Pavia, PaviaAges 18 years+ - NCT07288632Recruiting
Lung cancer gene test and blood clot risk study
This study looks at whether certain gene profiles in advanced lung cancer affect the risk of blood clots. It may help doctors better understand and prevent clots in people starting new cancer treatment.
Perugia, PerugiaAges 18 years+ - NCT07294807Recruiting
Salt substitute trial to prevent high blood pressure in pregnancy
This trial tests whether switching to a low-sodium salt substitute can help prevent high blood pressure disorders (like preeclampsia) during pregnancy. It is for pregnant people who are at increased risk and eat most meals at home.

Registry of hypertrophic cardiomyopathy: regional features, genetics and course
This study is a registry that collects information about people with hypertrophic cardiomyopathy (a condition where the heart muscle is thickened) to better understand how it affects different people and to study its genetic causes. By joining, you help researchers learn more about this condition and how it progresses.
Moscow, Moscow RegAges Any age - NCT07290842Recruiting
Dietary nitrate for high blood pressure kidney injury
This study tests whether a natural substance found in leafy greens (dietary nitrate) can help protect the kidneys of people with high blood pressure and early kidney damage. It may offer a simple dietary way to slow kidney disease.
HerningAges 18–70 - NCT07292272Recruiting
Slowing Aging in Blood Cancer Survivors
This study tests a program to help people who have survived a blood cancer stay healthier as they age. It involves exercise and check-ups to see if we can slow down some effects of aging.
Omaha, NebraskaAges 50 years+ - NCT07294937Recruiting
10-year heart health check for people screened in Casablanca
This study checks on people who had a heart health screening 10 years ago to learn more about heart risks and develop a risk score just for Moroccans. Researchers will contact you to see how your heart health is now and what might have changed.
CasablancaAges 40 years+ - NCT07294625RecruitingEarly Phase 1
Gene therapy for relapsed/refractory multiple myeloma
This trial tests a new gene therapy, LVIVO-TaVec200, for people with multiple myeloma that has returned or not responded to other treatments. The goal is to see if it can help control the cancer.
Zhengzhou, HenanAges 18 years+ - NCT07293832Recruiting
Beta-blocker therapy for heart attack patients
This trial tests a heart medication (a cardio-selective beta-blocker) given during a heart attack to see if it reduces damage to the heart muscle. It might help people having their first heart attack who are treated quickly with angioplasty (a procedure to open blocked arteries).
Thessaloniki, ThessalonikiAges 18–80 - NCT07293338Recruiting
Heart muscle blood flow study for dilated cardiomyopathy
This study looks at how small blood vessels in the heart affect outcomes in people with dilated cardiomyopathy (an enlarged, weak heart). You may qualify if you have heart failure with a weak pump and no significant blockages in your main heart arteries.
Hangzhou, ZhejiangAges 18 years+ - NCT07293364Recruiting
Study of C1-inhibitor test for hereditary angioedema diagnosis
This study checks if a blood test measuring C1-inhibitor function can help diagnose hereditary angioedema (HAE), a rare condition that causes painful swelling episodes. If you or a close family member have had swelling without rash or itching that lasts 1-5 days and doesn't get better with allergy meds, this trial may be for you.
