Detailed Description:

This is an open-label, multi-part, first-in-human, proof of concept study in infants with Type 1 spinal muscular atrophy who have exactly 2 copies of SMN2, to evaluate safety, tolerability, PK, PD and efficacy of oral branaplam after 13 weeks treatment.

Parts 1 and 2 are intended to be non-confirmatory. In Part 1 of the study, patients will be dosed once weekly with branaplam. The branaplam dose will be escalated in subsequent cohorts until MTD is determined or when sufficient PK results confirm that the MTD cannot be reached due to a potential pharmacokinetic plateau at higher doses. A decision to dose escalate the next cohort will be made after safety data have been collected for 14 days following the first dose (14-day DLT window). PK will be used to confirm that there is no accumulation of the compound.

Part 2 of the study will enroll new patients into one of up to 3 dose cohorts with once weekly dosing for 52 weeks. The branaplam dose will be escalated in subsequent cohorts after 6 patients have been enrolled and at least 3 patients from the previous cohort will have completed 13 weeks of treatment. After 52 weeks, patients may continue treatment if Novartis, the investigator and the independent DMC agree that this is in the best interest of the patient.

In all cases continuation of the treatment will be done at a dose selected as optimum, considering existing safety as well as efficacy data

Examples are medical disability other than SMA that would interfere with the assessment of safety or would compromise the ability of the subject to undergo study procedures including be assessed by CHOP INTEND motor scale, changes in hematologic parameters or gastrointestinal dysfunction that would compromise the ability of adequate assessment of safety
