Can a second treatment help kids with SMA who stalled after gene therapy?

NCT ID NCT05861999

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether adding risdiplam, a daily oral medicine, can help children under 2 with spinal muscular atrophy (SMA) who stopped getting better or started declining after receiving gene therapy. The study will enroll 28 children and measure changes in motor skills over 72 weeks. The goal is to see if risdiplam can improve movement and function beyond what gene therapy alone achieved.

What this could mean

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

Active substance

Risdiplam (a liquid medicine taken by mouth)

What this could lead to

If it works, this could offer a way to help children with SMA who have stopped improving after gene therapy regain some motor function.

What could go wrong

This is a small, early-phase study with only 28 children, so results may not apply to everyone. Risdiplam may cause side effects, and it is not known if it will reverse the plateau or decline.
