Colchicine to prevent another brain bleed from CAA
This trial tests if colchicine can reduce the risk of another stroke caused by bleeding in the brain due to a condition called cerebral amyloid angiopathy (CAA). You may qualify if you've recently had a brain bleed from CAA and have certain signs on brain scans.
BeijingAges 55 years+ - NCT07027891Recruiting
AI ECG test to rule out heart attack in chest pain patients
This study tests if an AI tool reading your ECG can quickly rule out a heart attack in people with chest pain. If you're having chest pain that might be a heart attack, but it's not a severe STEMI type, you may be able to join.

Long-term follow-up of cardiac arrest survivors who had ultra-rapid cooling
This trial checks on the long-term health of people who survived a cardiac arrest and received ultra-rapid cooling as part of an earlier study (OverCool). The goal is to see how they are doing over time.
AngersAges 18 years+ - NCT07028970Recruiting
Long-term follow-up study for equecabtagene autoleucel recipients
This registry study will follow people who have received the CAR T-cell therapy equecabtagene autoleucel to monitor their long-term health and outcomes. It is open to those who completed or withdrew from an earlier study of this treatment.
BeijingAges Any age - NCT07029503RecruitingPhase 2
Heart failure and kidney function study
This trial tests a new treatment for people with heart failure and severely reduced kidney function. It aims to see if the treatment can help protect both the heart and kidneys.
StockholmAges 18 years+ - NCT07029906Recruiting
Testing if beta-blocker side effects are due to expectations
This study tests whether some side effects from beta-blockers are caused by your expectations (the nocebo effect) rather than the drug itself. If you have heart failure and stopped a beta-blocker due to symptoms, this study may help understand your experience and potentially find better ways to manage it.
LondonAges 18 years+ - NCT07031739Recruiting
Managing high blood pressure and food insecurity
This study tests different ways to help people with high blood pressure who also struggle to get enough food. It aims to improve blood pressure control and reduce food insecurity.
Winston-Salem, North CarolinaAges 18 years+ - NCT07032129RecruitingPhase 1/Phase 2
Targeted cell therapy for multiple myeloma that returned or didn't respond
This trial tests a new type of treatment using your own immune cells (called CAR-T cells) that target two proteins on myeloma cells: BCMA and GPRC5D. It's for people whose myeloma has come back or stopped responding to standard treatments, and who may have few other options left.
Beijing, Beijing MunicipalityAges 21–90 - NCT07032714RecruitingPhase 1
Mezigdomide and talquetamab for relapsed multiple myeloma
This trial tests a combination of two drugs, mezigdomide (a pill) and talquetamab (an injection), for people with multiple myeloma that has come back or not responded to at least three prior treatments. The goal is to see if this combination can help control the disease.
Boston, MassachusettsAges 18 years+ - NCT07032792RecruitingPhase 2
FEIBA versus plasma for bleeding after heart surgery
This trial compares two treatments for bleeding after heart surgery: a medicine called FEIBA (which helps blood clot) and fresh frozen plasma (a blood product). The goal is to see which works better as a first treatment for bleeding during recovery.
Manhasset, New YorkAges 18 years+ - NCT07032987Recruiting
Improving sedation with a new care plan for ICU patients
This trial tests a new sedation protocol for adults in intensive care who need strong pain relief or sedation medicines. It aims to make sedation safer and more comfortable, and includes people on ECMO (a heart-lung machine) or a ventilator (breathing machine) for severe breathing problems.
London, LondonAges 18–100 - NCT07034157Recruiting
Ultrasound screening and treatment for artery disease
This study tests if using ultrasound to screen for blocked neck and head arteries can improve treatment plans for people getting heart artery stents. It aims to find hidden blockages and tailor therapy to reduce stroke and other risks.
BeijingAges 18 years+ - NCT07034599Recruiting
Negative pressure breathing after heart pump implant
This study looks at how a breathing machine that uses negative pressure (like a vacuum) affects the heart and blood flow in people who have a left ventricular assist device (LVAD), a type of heart pump. It may help doctors learn the best way to support breathing after surgery.
