Special Episode: FDA Greenlights Vamorolone for Duchenne Muscular Dystrophy
Nov 07, 2023, 08:00 PM
Welcome to this special episode of the NeurologyLive® Mind Moments® podcast. Tune in to hear leaders in neurology sound off on topics that impact your clinical practice. For major FDA decisions in the field of neurology, we release short special episodes to offer a snapshot of the news, including the main takeaways for the clinical community, as well as highlights of the efficacy and safety profile of the agent in question.
In this episode, we're covering the recent approval of vamorolone (Agamree; Santhera Pharmaceuticals) oral suspension 40 mg/mL for the treatment of patients with Duchenne muscular dystrophy (DMD) aged 2 years and older. The therapy is set to be acquired by Catalyst Pharmaceuticals soon, and is a first-in-class dissociative steroid that aims to retain the anti-inflammatory activity of corticosteroids while decreasing the deleterious adverse events (AEs). We spoke with Barry J. Byrne, MD, PhD, professor and associate chair of pediatrics and director of the Powell Gene Therapy Center at the University of Florida, who discussed the recent FDA approval of Santhera Pharmaceuticals investigational agent vamorolone (now marketed as Agamree, and soon to be acquired by Catalyst Pharmaceuticals in North America), its potential to affect the treatment paradigm as a first-in-class dissociative steroid, and important efficacy and safety information from the phase 2b VISION-DMD study (NCT03439670).
