Abstract
Generic drugs manufactured in Russia are increasingly being used in clinical practice. This article describes the experience of physicians in the Moscow Oblast of Russia in transitioning children with spinal muscular atrophy (SMA) from the reference formulation of nusinersen to its generic equivalent. We present a clinical case involving a child with type 2 SMA who initially received pathogenetic therapy with the reference nusinersen and was subsequently switched to the Russian-manufactured generic formulation. Improvements in motor function observed during treatment, as assessed by standardized functional motor scales, are reported. As a result, the Russian generic nusinersen demonstrated a favorable safety profile.
