Study Arms:
- Part 1 Group A: Adolescents and Adults (Risdiplam) (Type: EXPERIMENTAL): 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.
- Part 1 Group A: Adolescents and Adults (Placebo) (Type: PLACEBO_COMPARATOR): 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.
- Part 1 Group B: Children (Placebo) (Type: PLACEBO_COMPARATOR): 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.
- Part 1 Group B: Children (Risdiplam) (Type: EXPERIMENTAL): 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.
- Part 2: Placebo (Type: PLACEBO_COMPARATOR): 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.
- Part 2: Risdiplam (Type: EXPERIMENTAL): 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.

Based on this trial design, predict the completion outcome and termination type (if applicable).
