Can a new pill ease muscle weakness in myositis?
Disease control Not yet recruitingThis phase III trial tests whether the oral drug nerandomilast can improve symptoms of idiopathic inflammatory myopathies, a group of rare autoimmune diseases that cause muscle weakness and inflammation. Adults with active myositis are randomly assigned to take nerandomilast or a…

Could CAR-T cells tame autoimmune diseases? early safety trial launches
Disease control Not yet recruitingThis early-stage study tests whether a single infusion of a patient's own modified immune cells (CAR-T cells) is safe for people with severe autoimmune diseases like lupus, rheumatoid arthritis, or scleroderma that haven't improved with standard treatments. Only 6 adults aged 18-…
