Can clearing old cells boost brain and body in MS? new trial aims to find out
NCT ID NCT07270120
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests whether a combination of two drugs, dasatinib and quercetin, can safely remove aged, damaged cells that may contribute to inflammation and nerve damage in people with secondary progressive multiple sclerosis (MS). The study enrolls 30 adults aged 50-85 who have not taken MS medications recently and have noticed worsening symptoms. Participants take the drugs every two weeks for three months and are followed for one year to see if their physical and cognitive function improves.
