CAR-T cell therapy for active autoimmune disease flare-ups
This study tests an immune-cell treatment (CAR-T, called BRL-301) in people with certain autoimmune diseases that are active and hard to control. It may help your immune system calm down if standard treatments have not worked or your disease has returned.

Breath and heart tests to study lung disease stiffness
This study uses breath analysis and heart/electrical heart testing to look at how stiff the arteries are in people with long-term lung conditions. It may help researchers better understand lung disease effects on the cardiovascular system.
MoscowAges 18 years+ - NCT05706220Enrolling by invitation
Eye tests to measure visual speed in multiple sclerosis
This study tests how fast and how accurately your eyes process visual information and how eye movements look in people with multiple sclerosis. It may help researchers understand vision-related effects of MS using objective eye measurements.
