  • Part 2: Change From Baseline in the Total Motor Function Measure 32 (MFM-32) Total Score at Month 12 [ Time Frame: Baseline (Day-1) and Month 12 ]
    The Motor Function Measure 32 (MFM32) is a scale constructed for use in neuromuscular disorders. It comprises 32 items that evaluate physical function in three dimensions: D1 function related to standing and transfer; D2 axial and proximal function; D3 distal motor function. Tasks are scored with a 4-point Likert scale: 0 - cannot initiate the task or maintain the starting position; 1 - performs the task partially; 2 - performs the task incompletely or imperfectly; 3 - performs the task fully and "normally". The 32 scores are summed and expressed on a 0-100 scale for the MFM32 total score. Higher scores indicate increased motor function. A positive change from Baseline indicates improvement. MMRM analysis was performed based on primary efficacy hypothetical estimand, which included participants data assuming no prohibited medication intended for treatment of SMA was received and participants continued on their randomized treatment until the analysis time point at Month 12.

Study Arms  ICMJE
  • Experimental: Part 1 Group A: Adolescents and Adults (Risdiplam)
    Adolescent and adult participants aged 12-25 years will receive risdiplam for at least 12 weeks. Once the placebo-controlled period is completed and Part 2 dose is selected, participants will be switched to Part 2 dose and will be treated in an open-label phase.
    Intervention: Drug: Risdiplam
  • Placebo Comparator: Part 1 Group A: Adolescents and Adults (Placebo)
    Adolescent and adult participants aged 12-25 years will receive placebo matching to risdiplam for at least 12 weeks. Once placebo-controlled period is completed, participants will be first switched to their cohort risdiplam dose. After the Part 2 dose is selected, participants will be switched to Part 2 dose and will be treated in an open-label phase.
    Interventions:
    • Drug: Placebo
    • Drug: Risdiplam
  • Placebo Comparator: Part 1 Group B: Children (Placebo)
    Children aged 2-11 years will receive placebo matching to risdiplam for at least 12 weeks. Once placebo-controlled period is completed, participants will be first switched to their cohort risdiplam dose. After the Part 2 dose is selected, participants will be switched to Part 2 dose and will be treated in an open-label phase.
    Interventions:
    • Drug: Placebo
    • Drug: Risdiplam
  • Experimental: Part 1 Group B: Children (Risdiplam)
    Children aged 2-11 years will receive risdiplam for at least 12 weeks. Once the placebo-controlled period is completed and Part 2 dose is selected, participants will be switched to Part 2 dose and will be treated in an open-label phase.
    Intervention: Drug: Risdiplam
  • Placebo Comparator: Part 2: Placebo
    Participants aged 2-25 years will receive placebo matching to risdiplam for 12 months. After 12 months of treatment with placebo, participants will be switched to risdiplam (5 mg once daily for participants with a body weight (BW) >/=20kg or 0.25 mg/kg for participants with a BW <20) in a blinded manner and participants will continue with treatment until Month 24. After Month 24, participants will be offered the opportunity to enter the open-label phase.
    Interventions:
    • Drug: Placebo
    • Drug: Risdiplam
  • Experimental: Part 2: Risdiplam
    Participants aged 2-25 years will receive risdiplam at the dose selected based on the results from Part 1 of the study (5 mg once daily for participants with a body weight (BW) >/=20kg or 0.25 mg/kg for participants with a BW <20 kg), for 24 months. After 24-month treatment, participants will be offered the opportunity to enter the open-label phase.
