MS drug ofatumumab may shield brain cells, lab study suggests

This study looked at whether a multiple sclerosis (MS) drug called Ofatumumab (Kesimpta) can make immune cells less toxic to brain cells. Researchers took blood samples from 40 people with relapsing-remitting MS before and after 6 months of treatment. They tested if the chemicals released by immune cells after treatment were less damaging to mouse brain cells grown in a dish. The goal was to understand how the drug works, not to test a new treatment.
