CAR T-cell therapy for relapsed kappa myeloma
This trial tests a new treatment called CAR T-cells (your own immune cells engineered in the lab) designed to fight kappa-restricted multiple myeloma that has come back or stopped responding to standard drugs. The goal is to see if this treatment can help patients whose cancer has progressed despite previous therapies.
Melbourne, VictoriaAges 18 years+ - NCT07541560Recruiting
Group Activities and Music for Stroke Recovery
This study tests whether group leisure activities and music training can help people recover better after a stroke. You would participate in these activities during your hospital stay in the first few weeks after your stroke.

Mavacamten Treatment Patterns in Obstructive Heart Thickening
This study tracks how mavacamten (a heart medication) works in Japanese patients with obstructive hypertrophic cardiomyopathy—a condition where the heart muscle becomes abnormally thick and blocks blood flow. The trial aims to understand how well the treatment works and how doctors use it in real-world care.
Minato-ku, TokyoAges 18 years+ - NCT07542509Recruiting
Digital sound analysis for newborn heart screening
This study uses digital technology to analyze heart sounds in newborns under 30 days old. The goal is to develop a simple, non-invasive way to detect heart problems early using sound recordings.
Bologna, BOAges 1 week–4 weeks - NCT07542860Recruiting
Comparing two aspirin doses in older heart disease patients
This study compares whether a lower dose of aspirin (50 mg) works as well as a standard dose (100 mg) for older adults who have had heart attacks, strokes, or other heart and blood vessel problems. The goal is to find the safest effective dose to prevent future events.
BeijingAges 60 years+ - NCT07543562RecruitingPhase 3
Selenium supplement for heart failure patients
This study tests whether taking selenium (a mineral supplement) helps heart failure patients feel better and live longer. Researchers will follow patients over time to see if selenium reduces symptoms and hospital visits.
OsloAges 18 years+ - NCT07544771Recruiting
HeartLogic monitoring in heart failure patients
This study tests whether a special monitoring system in your heart device (called HeartLogic) can help detect early warning signs of heart failure getting worse. It uses wireless check-ins to track your condition at home and alert your doctor if you need help.
AmiensAges 18 years+ - NCT07545473Recruiting
Eye Imaging to Detect Brain Disease Markers
This study uses a special camera to photograph the back of your eye in detail. Researchers believe changes in the eye may reflect brain diseases like Alzheimer's or Parkinson's, and this imaging could help detect these conditions earlier.
Melbourne, VictoriaAges 30 years+ - NCT07546864Recruiting
Mirror Therapy vs. Daily Activity Training After Stroke
This study compares two rehabilitation approaches—mirror therapy (using a mirror to help retrain your affected side) and cognitive orientation to daily tasks—for people recovering from stroke. The goal is to see which method helps improve arm, hand, and leg function better.
Bayburt, MerkezAges 18 years+ - NCT07546877Recruiting
Brain Stimulation to Improve Memory After Stroke
This study tests whether a non-invasive brain stimulation technique called high-frequency repetitive transcranial magnetic stimulation (rTMS) can help improve thinking and memory problems that occur after a stroke. If you've had a stroke in the past year and are experiencing cognitive difficulties, this trial may help restore some of your mental abilities.
JinanAges 35–75 - NCT07547007Recruiting
Exercise Program to Improve Life Quality After Myeloma Treatment
This study tests whether a 6-month personalized exercise program—done partly at home and partly at a center—can improve quality of life for patients with multiple myeloma (a blood cancer) who are receiving ongoing chemotherapy or targeted drugs. The program is tailored to your abilities and fits into your regular hospital visits.
