Introduction • SMA is a severe, progressive neuromuscular disease leading to loss of motor function and reduced life expectancy1 • Increasing evidence suggests that SMA may be a multi-system disorder, where cells and tissues throughout the body, including motor neurons may be selectively vulnerable to low SMN protein levels3,4 • RG7916 is an orally administered, centrally and peripherally distributed SMN2 pre-mRNA splicing modifier that increases SMN protein levels • Preclinical data show similar RG7916 concentrations in blood, brain, and muscle tissue (Poster P48, A. Poirier et al.) • Similar SMN protein increase in brain and muscle in SMA mouse models following RG7916 administration (Poster P48) • Proof-of-mechanism of oral SMN2 splicing modifiers was previously established in preclinical models5 and in Type 2 and 3 SMA patients with RG79166 (Poster P46, E. Mercuri et al.) • The FIREFISH study aims to assess the safety and efficacy of RG7916 in babies with Type 1 SMA. This study is sponsored by F. Hoffmann-La Roche Ltd.

All rights reserved. • Working with patients with Type 1 SMA presents several challenges, mainly related to the age and the severity of the disease • Challenges can affect the infants, family, and staff involved in the studies • As SMA (and especially Type 1) is a rare and devastating disease, we are facing a GLOBALIZATION of clinical research • Families in countries where competing trials and therapies (eg, nusinersen) are not available may ask to be recruited to studies or to access therapies • This may accelerate recruitment and development of new treatments • Give access to potential treatment to a higher number of patients Tips from real-life experience during the implementation of the FIREFISH study

© 2018 F. Hoffmann-La Roche Ltd. All rights reserved. • Real-life experience from investigators must be used to best support patients and families during the FIREFISH trial • The importance of support from advocacy groups and patient/family organizations • Key considerations when conducting a study in Type 1 SMA include: • The need to coordinate a multi-disciplinary team of healthcare specialists dealing with such young babies • The support to relocate families away from their home country • The importance of assuring standard-of-care practices whilst patients participate in the trial Tips from real-life experience during the implementation of the FIREFISH study

© 2018 F. Hoffmann-La Roche Ltd. All rights reserved. • Families in countries where competing trials and therapies (eg, nusinersen) are not available may ask to be recruited to studies or to access therapies • Resource limitations and cultural differences • Relocation is important for the safety of the child and for the good conduct of the study Family relocation

All rights reserved. • A proactive and anticipatory approach is essential to modify the course of the disease • Changing phenotype should be paralleled and supported by the implementation of standard of care (eg, postural control or standing frame as long as the child reaches new motor milestones, etc) The application of SoC remains essential despite the emerging therapies • Need of consistency of management within the study (involving different sites in different countries) • Need for training and dissemination of experience among sites and countries SoC, standard of care. Clinical trials involving relocation should ensure multidisciplinary management

© 2018 F. Hoffmann-La Roche Ltd. All rights reserved. Conclusions • To date, RG7916 has been safe and well tolerated at all doses and there have been no drug-related safety findings leading to withdrawal in any SMA patients exposed to RG7916 • Ophthalmologic monitoring did not show any evidence of the retinal toxicity seen in preclinical monkey studies in any patient exposed to RG7916 • Early interim clinical data reported:  No patient lost the ability to swallow  No patient has required tracheostomy or reached permanent ventilation • Important considerations in conducting such clinical studies:  Co-ordination of a multi-disciplinary team  Family relocation  Application of standard-of-care practices • Study updates will continue to be communicated at congresses in 2018 • Part 2 of the study is expected to start in Q1 2018
