Background

Risdiplam is an orally bioavailable mRNA splicing modifier used for the treatment of spinal muscular atrophy (SMA). It increases systemic SMN protein concentrations by improving the efficiency of SMN2 gene transcription. This mechanism of action is similar to its predecessor nusinersen, the biggest difference being their route of administration: nusinersen requires intrathecal administration, as does the one-time gene therapy onasemnogene abeparvovec, whereas risdiplam offers the ease of oral bioavailability.

Risdiplam was approved by the FDA in August 2020 for the treatment of spinal muscular atrophy (SMA). Set to be substantially cheaper than other available SMA therapies, risdiplam appears to provide a novel and relatively accessible treatment option for patients with SMA regardless of severity or type.

Indication

Risdiplam is indicated for the treatment of spinal muscular atrophy (SMA).
