Abstract
Duchenne muscular dystrophy (DMD) is a severe inherited neuromuscular disorder characterized by a dystrophin gene mutation, leading to progressive muscle weakness and structural degradation. Current management strategies focus on multidisciplinary approaches to mitigate symptoms and enhance quality of life. Conventional glucocorticoids present challenges due to their complex nature and severe side effects. Vamorolone, a first-in-class dissociative steroidal drug recently Food and Drug Administration (FDA) - approved, distinguishes itself through enduring anti-inflammatory effects with reduced safety concerns. Pharmacologically, Vamorolone's mechanism of action, differentiating it from traditional corticosteroids, involves selective glucocorticoid receptor (GR) modulation and mineralocorticoid receptor (MR) antagonism, offering improved safety and tolerability. Notably, its unique ?9,11 modification prevents adverse receptor interactions, demonstrating superior safety in inhibiting inflammation across various cell types. This article explores Vamorolone's pharmacokinetics, drug interactions, and adverse effects, underscoring its well-tolerated profile with reversible hypothalamic-pituitary-adrenal axis suppression as a notable concern. Comparative studies against prednisone reveal Vamorolone's efficacy in improving muscle strength with minimal side effects, validated through the pivotal Phase IIb VISION-DMD study. Ultimately, Vamorolone has attained a breakthrough status in DMD treatment. Its endorsement by the FDA underscores Vamorolone as a transformative linchpin, heralding a new era in revolutionizing DMD care.
