Participant Flow
Recruitment Details | Overall, 26 infants with spinal muscular atrophy (SMA) were enrolled in the study across 7 different sites in 7 countries. |
Pre-assignment Details | The study enrolled infants aged from birth to 6 weeks who were genetically diagnosed with SMA but were not yet presenting with symptoms. Study arms were based on the number of copies of the SMN2 gene. |
Arm/Group Title | 2 SMN2 Copies, Risdiplam | 3 SMN2 Copies, Risdiplam | >/=4 SMN2 Copies, Risdiplam |
---|---|---|---|
Arm/Group Description | Infants with 2 copies of SMN2 were enrolled to receive risdiplam orally once daily at a dose selected to achieve the targeted exposure range of close to 2000 ng*hr/mL. | Infants with 3 copies of SMN2 were enrolled to receive risdiplam orally once daily at a dose selected to achieve the targeted exposure range of close to 2000 ng*hr/mL. | Infants with 4 or more copies of SMN2 were enrolled to receive risdiplam orally once daily at a dose selected to achieve the targeted exposure range of close to 2000 ng*hr/mL. |
