Quincy-sous-SénartAges 18 years+ - NCT05641753RecruitingPhase 4
LDL-lowering study for adults with type 1 diabetes
This study looks at cholesterol lowering in adults with type 1 diabetes and whether it reduces “residual risk,” meaning risk that may remain even with current care. You may be asked to take cholesterol-focused treatment and complete blood tests to track LDL (“bad cholesterol”).
New York, New YorkAges 18–89 - NCT05766670RecruitingPhase 3
Calcium and antibiotic placed inside tibia nail for open fractures
This Phase 3 study tests whether a calcium/antibiotic “depot” released from an intramedullary nail can lower infection risk in certain open tibia fractures. It may help by delivering antibiotics right at the fracture area while the nail fixes the bone.
Los Angeles, CaliforniaAges 18 years+ - NCT05786417RecruitingPhase 4
Medication comparison for older adults with stable heart pain
This trial tests which heart medications work best for older adults who have stable angina (predictable chest pain) and multiple other long-term health problems. You may be asked to start or adjust medications and attend regular follow-up visits to see which approach controls symptoms and outcomes.
New Haven, ConnecticutAges 65 years+ - NCT05845424RecruitingPhase 4
High-intensity cholesterol pills for people with silent calcium
This trial studies whether high-intensity statin plus ezetimibe can improve heart health in people who do not have symptoms but have calcium buildup in their heart arteries. It may help lower cholesterol and reduce future heart risks for the right participants.
SeoulAges 40 years+ - NCT05961488Recruiting
Coronary CT scan after cardiac arrest to check heart artery blockage
This trial tests whether a special CT scan (coronary CT angiography) can help rule out coronary artery disease—the common artery blockage causing heart problems—after someone has survived an out-of-hospital cardiac arrest. It may help doctors quickly decide who needs or does not need further heart procedures.
ReimsAges 18 years+ - NCT06041477RecruitingPhase 3
Combining treatments for liver cancer before surgery
This study tests whether giving targeted therapy and immunotherapy at the same time or one after the other is better for shrinking liver tumors that can't be removed right now but might be removable after treatment.
Guangzhou, GuangdongAges 18–75 - NCT06061549RecruitingPhase 1
Gene therapy for stiff heart failure (preserved EF)
This trial tests a one-time gene therapy for people with heart failure who still have normal pumping strength (preserved ejection fraction). It aims to improve how heart cells handle calcium, which may help the heart relax better and ease symptoms.
Durham, North CarolinaAges 50 years+ - NCT06102863RecruitingPhase 2
Progesterone and statins for young women with early endometrial cancer or atypical hyperplasia
This trial tests whether adding a statin to progesterone therapy helps young women with early endometrial cancer or atypical endometrial hyperplasia who want to preserve their fertility. It aims to find a better treatment option for those who may not respond well to progesterone alone.
Beijing, Beijing MunicipalityAges 17–45 - NCT06207253RecruitingPhase 2/Phase 3
Testing diclofenac gel for tooth root infections
This trial tests whether a special anti-inflammatory gel (diclofenac sodium) placed inside the tooth can help treat an infection at the root tip. It is for adults with a restorable tooth and no allergies to the medication.
CairoAges 18–50 - NCT06235112Recruiting
AI Screening for Heart Calcium from Chest CT Scans
This research study uses an artificial intelligence program to screen old chest CT scans for calcium buildup in the heart arteries. If you are between 40 and 75 and have had a chest CT in the last 3 years, this may help identify if you are at risk for heart disease so you can take steps to prevent it.
Boston, MassachusettsAges 40–75 - NCT06247787RecruitingPhase 1
Imetelstat plus chemo for relapsed leukemia in kids
This trial tests a new drug called imetelstat combined with two chemotherapy drugs (fludarabine and cytarabine) for children and teens with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or juvenile myelomonocytic leukemia (JMML) that has come back or not responded to treatment. The goal is to find the safest dose of imetelstat and see if it helps control the cancer.
Birmingham, AlabamaAges 1–18 - NCT06259149Recruiting
