Overview of SMA 4 SMA is a devastating orphan disease that results in motor neuron loss and progressive weakness; it is the most common genetic cause of infant death Incidence: ~1 in 10,000 live births Caused by reduced SMN (survival motor neuron) protein levels from loss of/defective SMN1 gene SMA divided into sub-categories, Type 1- 4, with Type 1 being most severe Severity correlates with # of copies of SMN2 backup gene Current treatments limited to palliative care

Children with SMA Type 1 Do Not Reach Any Major Motor Milestones Retrospective Study from large multi-center datasets (US and EU) Patients (n=33) have genetically confirmed homozygous deletion of exon 7 in SMN1 gene; categorized according to Dubowitz’s decimal classification (confirmation of SMN1 status and clinical observations) Study visits at baseline, every 2-3 months until the age of 12 months, and every 6 months thereafter, when possible Hammersmith Infant Neurological Examination (HINE) used to assess intermediate steps leading to full achievement of milestones DESIGN Prolongation of survival with supportive care does not impact achievement of motor milestones in SMA Type 1 infants SMA Type 1 infants with symptom onset <6 months: Will not reach any major motor milestones, such as sitting, crawling, standing, and walking Any early intermediate milestones in 1B patients will be quickly lost The highest milestone achieved is seen in the child’s first visit followed by a rapid decline Any improvement or achievement of milestones not usually achieved in a child with SMA Type 1 in a drug intervention trial can be attributed to the drug and not due to survival or enhanced standard of care CONCLUSIONS Developmental Milestones in Type 1 Spinal Muscular Atrophy De Sanctis et al.

AVXS-101 Pivotal Trial in SMA Type 1 Update Based on Ongoing Dialogue and FDA Type B Meeting Minutes Held 9/30/16 17 Study Overview To reflect single-arm design with a natural history comparator Expected to enroll approximately 20 patients Endpoints to include safety, achievement of motor milestones (e.g. ability to sit unassisted), event-free survival Additional trial design details to be provided at time of initiation Acknowledged company’s rationale for single-arm trial Indicated preference for co-primary endpoints consisting of developmental milestones and a clinically meaningful measure of survival Strongly recommended end-of-Phase 1 meeting to evaluate adequacy of data from ongoing study to support future product development, including discussion of whether these data may provide the substantial evidence needed to support a marketing application FDA feedback in late December 2016 on protocol submission resulted in continued alignment on single-arm design and endpoints FDA Feedback Next Steps Complete ongoing Phase 1 trial and continue collaborative discussions with FDA regarding most expeditious pathway for approval Planned trial start in H1’17

SMA Type 2 Strategy Potentially streamlines development of Type 2 clinical data set Eliminates the need for a comparability analysis later in development Simplifies the development pathway by using one, consistent product; FDA in general prefers use of a consistent product process in program development, if at all possible Potentially accelerates the timeframe for gathering clinical data that may be used as part of a data set to support a future SMA Type 2 indication Plan to initiate Type 2 study in Q2 2017, assuming a positive outcome from the planned Type B manufacturing meeting This strategy does not impact the development program for Type 1 Optimal approach to use scalable GMP-derived product in clinical evaluation of AVXS-101 in SMA Type 2 18
