Roche Evrysdi tablet gets European Commission approval for Spinal Muscular Atrophy

Basel: Roche has announced that the European Commission (EC) has approved a label extension for Evrysdi (risdiplam) to include a new, room-temperature stable tablet for people living with spinal muscular atrophy (SMA).
The 5mg tablet (approx. 6.5mm), which can either be swallowed whole or dispersed in water, can be taken with or without food and does not require refrigeration, when stored at room temperature. Administered at home, Evrysdi is a non-invasive disease modifying treatment available for people living with SMA.
“The new Evrysdi tablet with its flexible administration represents progress toward more versatile SMA disease management," said Levi Garraway, M.D., Ph.D., Chief Medical Officer and Head of Global Product Development, Roche. “With over 18,000 people treated to date, Evrysdi’s proven efficacy, safety and convenience has significantly improved the course of disease for people living with SMA.”
Evrysdi is designed to treat SMA by increasing and sustaining the production of SMN protein throughout the entire central nervous system (CNS) and in peripheral tissues.
“We welcome the development of new treatment formulations that have the potential to further simplify disease management and care for people living with SMA,” Nicole Gusset, Chief Executive Officer, SMA Europe commented. “This is a disease requiring daily management, and it is paramount that people living with SMA, and those who care for them, are given options to optimise treatment administration.”
The approval is based on data from a bioequivalence study (NCT04718181) evaluating the 5mg tablet formulation of Evrysdi, which can either be swallowed whole or dispersed in water. Results presented at SMA Europe’s 4th Scientific International Congress in 2024 demonstrated that the tablet formulation and original oral solution provided bioequivalence to Evrysdi, meaning individuals taking the tablet can expect the same established efficacy and safety as the oral solution.
The 5mg tablet formulation is suitable for people two years of age or older, who weigh 20kg (44 lbs) or more and are able to swallow without the use of a feeding tube. The original oral solution will remain available for those on other doses of Evrysdi and for those who may prefer the oral solution.
Roche leads the clinical development of Evrysdi as part of a collaboration with the SMA Foundation and PTC Therapeutics.
Evrysdi was granted PRIME designation by the European Medicines Agency (EMA) in 2018 and Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) in 2017. In 2021, Evrysdi was awarded Drug Discovery of the Year by the British Pharmacological Society as well as the Society for Medicines Research Award for Drug Discovery. Evrysdi is currently approved in more than 100 countries, with more than 18,000 people with SMA treated globally.
Evrysdi is currently being, or has been, evaluated in numerous global multicenter trials in people with SMA:
- FIREFISH (NCT02913482) – an open-label, two-part pivotal clinical trial in infants with Type 1 SMA. Infants were approximately 5.5 months of age (median) at the time of enrollment and of the 58 infants that completed the first year of treatment, 52 entered the open-label extension study. The study met its primary endpoint and has concluded after 5 years of follow up.
- SUNFISH (NCT02908685) – a two-part, double-blind, placebo-controlled pivotal study in people aged 2-25 years with Types 2 or 3 SMA. The study met its primary endpoint and has concluded after five years of follow up.
- JEWELFISH (NCT03032172) – an open-label exploratory trial designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamics in people with SMA aged 6 months to 60 years who received other investigational or approved SMA therapies prior to receiving Evrysdi. The study has completed recruitment (n=174).
- RAINBOWFISH (NCT03779334) – an open-label, single-arm, multicenter study, investigating the efficacy, safety, pharmacokinetics, and pharmacodynamics of Evrysdi in babies (n=26), from birth to 6 weeks of age (at first dose) with genetically diagnosed SMA who are not yet presenting with symptoms. The study met its primary endpoint.
- MANATEE (NCT05115110) – a Phase II/III clinical study to evaluate the safety and efficacy of GYM329 (RG6237), an anti-myostatin molecule targeting muscle growth, in combination with Evrysdi for the treatment of SMA in patients 2-10 years of age. The FDA Office of Orphan Products Development granted GYM329 Orphan Drug Designation for the treatment of patients with SMA in December 2021. The study is currently recruiting.
- HINALEA 1 (NCT05861986) and HINALEA 2 (NCT05861999) – Phase IV clinical studies to evaluate the effectiveness and safety of Evrysdi in patients under 2 years of age at enrollment, who received onasemnogene abeparvovec gene therapy either pre-symptomatically or post-symptomatically, following a genetically confirmed diagnosis of 5q–autosomal recessive SMA. The studies are currently recruiting.
- PUPFISH (NCT05808764) – a Phase II, open-label study to investigate the pharmacokinetics and safety of Evrysdi in babies with SMA who are under 20 days of age (at first dose). The study is currently recruiting.
