PR Newswire

SOUTH PLAINFIELD, N.J., Oct. 21, 2020 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) today announced that Evrysdi™ (risdiplam) was approved in Brazil by the National Health Surveillance Agency (ANVISA) for the treatment of spinal muscular atrophy (SMA). The approval was obtained within seven months of Roche's initial submission and marks the second country to approve Evrysdi™. Additionally, PTC announced the filing of a New Drug Application (NDA) for Evrysdi™ for the treatment of SMA with the Japanese Ministry of Health, Labor and Welfare (MHLW). The filing in Japan by Chugai Pharmaceutical Co. Ltd., a member of the Roche group, triggers a $7.5 million milestone payment to PTC from Roche.

"We are very pleased with both the rapid approval in Brazil as well as the filing of Evrysdi™ in Japan," said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics. "These important achievements continue to build momentum for Evrysdi™ globally, and we are working hard alongside our partners in the collaboration to make the medicine available to SMA patients around the world. The strong efficacy, excellent safety profile, and convenient oral formulation of Evrysdi™ are so important to the SMA community. Access to a home administered therapy is particularly important during the COVID-19 pandemic."

The NDA in Japan is based on data from the FIREFISH study in infants aged 1 to 7 months old with symptomatic Type 1 SMA and the SUNFISH study in children and young adults with Type 2 or 3 SMA. MHLW previously granted orphan drug designation to risdiplam and the NDA application is subject to priority review.

The U.S. Food and Drug Administration (FDA) approved Evrysdi™ (risdiplam) in August 2020, for the treatment of SMA for adults and children 2 months and older. At this time, applications have been filed for Evrysdi™ in 15 international markets: Australia, Chile, India, Indonesia, Israel, Kuwait, Macedonia, Malaysia, Russia, Singapore, South Korea, Taiwan, Thailand, Ukraine and the United Arab Emirates. In addition, four health authorities worldwide are currently reviewing the application: Canada, China, the European Union and Switzerland.

Evrysdi™ is based on PTC science and is commercialized in the United States by Genentech, a member of the Roche Group. Roche leads the clinical development of Evrysdi™ as part of a collaboration with the SMA Foundation and PTC Therapeutics.

About Spinal Muscular Atrophy (SMA)
Spinal muscular atrophy (SMA) is a severe, progressive neuromuscular disease that can be fatal. It affects approximately 1 in 10,000 babies and is the leading genetic cause of infant mortality. SMA is caused by a mutation of the survival motor neuron 1 (SMN1) gene, which leads to a deficiency of SMN protein. This protein is found throughout the body and is essential to the function of nerves that control muscles and movement. Without it, nerve cells cannot function correctly, leading to muscle weakness over time. Depending on the type of SMA, an individual's physical strength and their ability to walk, eat or breathe can be significantly diminished or lost.

About Evrysdi™ (risdiplam)
Evrysdi™ is a survival motor neuron 2 (SMN2)-directed RNA splicing modifier designed to treat SMA caused by mutations in chromosome 5q that lead to SMN protein deficiency. Evrysdi™ is designed to distribute evenly to all parts of the body, including the central nervous system (CNS). Evrysdi™ is administered daily at home in liquid form by mouth or feeding tube. The U.S. Food and Drug Administration recently approved Evrysdi™ (risdiplam) for the treatment of spinal muscular atrophy for adults and children 2 months and older. Evrysdi™ (risdiplam) is marketed in the United States by Genentech, a member of the Roche Group.

About the Risdiplam Clinical Studies

FIREFISH (NCT02913482) - an open-label, two-part pivotal clinical trial in infants with Type 1 SMA. Part 1 was a dose-escalation study in 21 infants with the primary objective of assessing the safety profile of risdiplam in infants and determining the dose for Part 2. Part 2 is a pivotal, single-arm study of risdiplam in 41 infants with Type 1 SMA treated for two years followed by an open-label extension. Enrollment for Part 2 was completed in November 2018. The primary objective of Part 2 was to assess efficacy as measured by the proportion of infants sitting without support after 12 months of treatment, as assessed in the Gross Motor Scale of the Bayley Scales of Infant and Toddler Development - Third Edition (BSID-III) (defined as sitting without support for five seconds). The study met its primary endpoint.

SUNFISH (NCT02908685) - SUNFISH is a two part, double-blind, placebo controlled pivotal study in people aged 2 to 25 years with Types 2 or 3 SMA. Part 1 (n=51) determined the dose for the confirmatory Part 2. Part 2 (n=180) evaluated motor function using total score of Motor Function Measure 32 (MFM-32) at 12 months. MFM-32 is a validated scale used to evaluate fine and gross motor function in people with neurological disorders, including SMA. The study met its primary endpoint.

Clinical Trial Safety Data

The safety profile of Evrysdi™ was established across FIREFISH and SUNFISH pivotal trials. The most common adverse reactions in later-onset SMA (incidence of at least 10 percent of patients treated with Evrysdi™ and more frequently than control) were fever, diarrhea, and rash. The most common adverse reactions in infantile-onset SMA were similar to those observed in later-onset SMA patients. Additionally, the most common adverse reactions (incidence of at least 10 percent) were upper respiratory tract infection, pneumonia, constipation, and vomiting.

In addition to FIREFISH and SUNFISH, Evrysdi™ is being evaluated in a broad range of people with SMA, including in:

JEWELFISH (NCT03032172) - an open-label exploratory trial designed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) in people with SMA aged 6 months to 60 years who received other investigational or approved SMA therapies for at least 90 days prior to receiving Evrysdi™. The study has completed recruitment (n=174).

RAINBOWFISH (NCT03779334) - an open-label, single-arm, multi-center study, investigating the efficacy, safety, pharmacokinetics, and pharmacodynamics of risdiplam in babies (~n=25), from birth to 6 weeks of age (at first dose), with genetically diagnosed SMA, who are not yet presenting with symptoms. The study is currently recruiting.
