- Drug: Risdiplam
- Biallelic SMN1 deletions

- Confounding neuromuscular disorder other than SMA
Protocol Summary
Risdiplam Exchange (RISE) is a study of spinal muscular atrophy (SMA) patients who crossover to 36 months of open-label risdiplam monotherapy following a comparable period of nusinersen treatment. The schedule of assessments (SOAs) carry over seamlessly for the cohort from studies done while treated with nusinersen and continue to track the most informative outcomes from that trial (e.g. nine hole peg test and grip strength), while adding the Box and Block Test (BBT) as an additional measure of upper limb endurance and function.
