mdx mouse (dystrophin-deficient) proof-of-concept studies with vamorolone
“In vivo proof-of-concept studies were conducted in mdx mice, which harbor a nonsense point mutation in exon 23 that results in production of a truncated and nonfunctional dystrophin protein.”
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
EMA: mdx comparison against a low prednisolone dose (5 mg/kg/day) hampers reliable evaluation of benefits and side effects
“Despite similar molecular weights, oral vamorolone doses between 5 to 30 mg/kg/day were compared with a low 5 mg/kg/day prednisolone dose in mdx mice and in another mouse model of acute lung inflammation, which hampers to reliably evaluate the benefits and side effects of the two corticosteroids.”
