Dapagliflozin for type 2 diabetes with high blood pressure
This trial studies whether dapagliflozin (the medicine in Trudapa tabs) is safe and works in people who have both type 2 diabetes and high blood pressure. It may help control blood sugar and blood pressure, while researchers closely watch for side effects.
Incheon, Namdong-guAges 19 years+ - NCT05971394Recruiting
Sirolimus stent for severe blocked leg arteries
This trial tests a special stent-like device placed in blocked arteries below the knee to improve blood flow in people with critical limb ischemia. If you meet the artery and health requirements, the goal is to reduce artery re-blocking and help prevent worsening leg problems over 12 months.
FlorenceAges 18–85 - NCT05971225Recruiting
Testing remote heart monitoring to improve heart outcomes
This study checks whether starting remote wireless heart monitoring for people with heart failure helps improve important heart outcomes. It may help your care team catch warning signs earlier by receiving your heart data from home.
Suwon, Kyonggi DoAges 20 years+ - NCT05971446Recruiting
Healthy Little Eyes study for newborn vision and brain health
This study looks at eye and vision outcomes in babies who have had lack of oxygen around birth (HIE) and also compares them with healthy “well babies.” It may help doctors better understand how HIE affects the eyes and what to watch for over time.
Madison, WisconsinAges Up to 3 years - NCT05972070Recruiting
Telemedicine home cardiac rehab after heart procedure
This trial studies whether cardiac rehabilitation done at home, with help from telemedicine, is safe and helps you stick with the program after a recent heart procedure. It may help you recover with more convenience while still improving heart-related fitness and adherence.
Brookfield, ConnecticutAges 18 years+ - NCT05972018RecruitingPhase 4
Liposomal numbing medicine for belly incisions in vascular surgery
This study compares two numbing options for pain control after open belly (mid-abdominal) vascular surgery: a longer-lasting numbing drug in the belly muscle layer versus a different numbing drug and catheter. It aims to see which approach better reduces postoperative pain and opioid use, and may help improve recovery.
Hartford, ConnecticutAges 18–80 - NCT05972135RecruitingPhase 2
Outpatient injections for multiple myeloma with teclistamab or talquetamab
This Phase 2 trial tests two antibody medicines (teclistamab or talquetamab) given as outpatient injections, to treat multiple myeloma. It also tests preventing and treating side effects with supportive medicines, aiming to improve disease control in people who have already tried other myeloma treatments.
Tucson, ArizonaAges 18 years+ - NCT05972356Recruiting
How heart relaxation affects outcomes in heart surgery
This study looks at whether a measurement of how well the heart relaxes helps predict outcomes after heart surgery. It focuses on patients treated in Amsterdam UMC and uses care data to understand who may be at higher or lower risk.
Amsterdam, North HollandAges 18 years+ - NCT05974150Recruiting
Remote symptom monitoring for several blood and cancer types
This study checks how well remote (at-home) symptom check-ins work for people with certain cancers. It may help patients and clinicians spot problems earlier and improve day-to-day care during treatment and beyond.
New Haven, ConnecticutAges 18 years+ - NCT05976152RecruitingPhase 3
Butyphthalide to improve thinking after a recent stroke
This Phase 3 study tests whether butyphthalide can help thinking and memory improve after an acute ischemic stroke. It compares people who take the study medicine versus usual care, and measures cognitive (thinking) changes over follow-up.
Dandong, LiaoningAges 60 years+ - NCT05977049Recruiting
