Vamorolone is an investigational drug that was developed as a novel dissociative steroidal anti-inflammatory. This means that its chemical profile is such that it shows chemical separation of efficacy (clinical benefit) from some safety concerns (side effect profiles) typically seen with corticosteroids, such as negative effects on growth and bone. Vamorolone is being tested in children that are otherwise chronically treated with corticosteroids. It is hoped that this is the patient population where it may show the most benefit.
