Primary Outcome(s)

Main Objective: Part 1:
•To evaluate the safety, tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) of RO7034067 in patients with Type 2 and Type 3 (ambulant or non-ambulant) SMA, and to select the dose for Part 2 of the study

Part 2:
•To evaluate efficacy of RO7034067 compared to placebo in terms of motor function in Type 2 and non-ambulant Type 3 SMA patients, as assessed by the change from baseline in the total score of the Motor Function Measure (MFM) at 12 months
