Updates in the Use of Vamorolone and Steroids in the Treatment of Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is a devastating, life-limiting neuromuscular disorder that has a global prevelance of 21.4 cases per 100,000 live male births. DMD is caused by mutations in the dystrophin gene, which is integral to muscle membrane stability. Mutations in the dystrophin gene lead to inflammation and muscle fibrosis. Current standard-of-care treatments include the use of chronic (or classic) corticosteroids, which can cause significant side effects. Vamorolone is a first-in-class dissociative steroid that acts as a partial agonist to glucocorticoid receptors but as an antagonist to mineralocorticoid receptors, leading to a more favourable side effect profile. Clinical data has shown that vamorolone has similar anti-inflammatory benefits to classic corticosteroids but an improved side effect profile. [ABSTRACT FROM AUTHOR]
