Summary

This phase 3 study tests a drug called salanersen (BIIB115) in people aged 15-60 with spinal muscular atrophy (SMA). The drug is designed to help the body produce more of a protein needed for nerve and muscle function. Participants receive an injection into the spine once a year for up to 5 years. The study includes people who have never been treated for SMA and those who have taken risdiplam. Researchers will measure changes in motor function using movement tests and track any side effects.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

salanersen (BIIB115)

What this could lead to

If successful, this could provide a new treatment option for spinal muscular atrophy that helps improve or stabilize motor function with once-yearly dosing.

What could go wrong

This is an early-phase open-label study with no placebo group, so results may be less reliable. The drug requires injection into the spine, which carries risks like headache or infection. It may not work for everyone.
