Key exclusion criteria

* Presence of clinically relevant ECG abnormalities before study drug administration; corrected QT interval using Bazett's method > 460 ms; personal or family history (first degree relatives) of congenital long QT syndrome indicating a safety risk for patients as determined by the investigator. First-degree atrioventricular block or isolated right bundle branch block are allowed
* The infant (and the mother, if breastfeeding the infant) taking any inhibitor of CYP3A4 taken within 2 weeks, any inducer of CYP3A4 taken within 4 weeks, any OCT 2 and MATE substrates within 2 weeks and known FMO1 or FMO3 inhibitors or substrates
* Clinically significant abnormalities in laboratory test results
* Ascertained or presumptive hypersensitivity to risdiplam or to the constituents of its formulation
* Treatment with oral salbutamol or another beta-2 adrenergic agonist taken orally for SMA is not allowed. Use of inhaled beta-2 adrenergic agonists is allowed
