Chicago, IllinoisAges 6–17 - NCT05042219Recruiting
How lung disease treatment may affect heart function
This study looks at how common long-term lung conditions and their treatments may change heart function. It uses heart imaging (an MRI) to see what’s happening, which could help doctors better monitor heart risks in people with lung disease.
AachenAges 18–99 - NCT05048862Recruiting
Brain scan and tests for neuromuscular conditions
This study compares people with neuromuscular disorders to healthy people using questionnaires and brain/neurological tests. It may help researchers understand how these conditions affect the brain and nervous system.
TaipeiAges 20 years+ - NCT05051072Recruiting
MRI study in adults with trigeminal neuralgia pain
This study uses a special MRI scan to look at how the trigeminal nerve system is working in people with essential trigeminal neuralgia (face pain) and whether there is nerve involvement. You may be asked to get MRI scans while resting, which can help doctors better understand the cause and guide future treatments.
ParisAges 18 years+ - NCT05061368RecruitingPhase 2
Sildenafil by mouth to improve breathing in COPD
This Phase 2 trial tests whether sildenafil tablets can improve exercise ability, shortness of breath, and heart-lung function in people with COPD. It also compares against people without COPD to better understand how sildenafil affects breathing tests.
Edmonton, AlbertaAges 40–80 - NCT05061953Recruiting
Eye-tracking test software study in adults with multiple sclerosis
This study checks how well new eye-tracking software can measure eye movements in people with multiple sclerosis. It may help researchers track changes in how the nervous system works using a simple camera-based eye test.
Montreal, QuebecAges 18 years+ - NCT05062369Recruiting
Brain stimulation plus training to support alcohol abstinence
This study tests whether a combination of brain stimulation (tDCS) and cognitive training can help people with alcohol use disorder stay abstinent. You may be included if you are currently not drinking and can commit to the program timeline.
Minneapolis, MinnesotaAges 18–65 - NCT05065372RecruitingPhase 1
