Basel, 20 May 2021 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the Swiss agency for therapeutic products (Swissmedic) has approved Evrysdi™ (risdiplam) for the treatment of 5q spinal muscular atrophy (SMA) in patients two months of age and older. SMA is a leading genetic cause of death in infants, and 5q SMA is the most common form of the disease. The condition causes muscle weakness and progressive loss of movement, and significant unmet need remains, particularly in adults living with this condition.
“We are pleased to be able to provide a new treatment option for people living with SMA in Switzerland. Evrysdi represents the first and only SMA treatment with proven efficacy that can be taken at home,” said Jean-Marc Häusler, M.D., Roche’s Country Medical Director in Switzerland. “By avoiding the need for in-hospital administration, Evrysdi can reduce the treatment burden on those living with SMA, their caregivers and the healthcare system.”
The approval is based on data from two clinical studies, designed to represent a broad spectrum of people living with SMA: FIREFISH in symptomatic Type 1 infants aged 2 to 7 months and SUNFISH in symptomatic Type 2 and 3 children and adults aged 2 to 25 years. SUNFISH is the first and only placebo-controlled trial to include adults with Types 2 and 3 SMA. Evrysdi demonstrated a favourable efficacy and safety profile, with the safety profile established across both trials.
The approval of Evrysdi was handled according to the Swissmedic fast track procedure. Swissmedic's accelerated approval procedure grants fast access to new therapies if the following conditions are cumulatively fulfilled: a. It is a promising prevention or therapy against a serious, disabling or life-threatening disease. b. Treatment options with previously approved drugs are either unavailable or unsatisfactory. c. A high therapeutic benefit is expected from the use of the new drug.
Evrysdi has been approved in 40 countries and submitted in a further 33 countries.
About FIREFISH
In FIREFISH, 29% (12/41; p<0.0001 compared to natural history) of infants treated with Evrysdi for 12 months were able to sit without support for at least five seconds, as assessed by the Gross Motor Scale of the Bayley Scales of Infant and Toddler Development Third Edition. This is a key motor milestone never achieved in the natural history of Type 1 SMA. In addition, 93% (38/41) of infants were alive and 85% (35/41) were event-free (alive with no permanent ventilation). Furthermore, 5% (2/41) of infants were able to stand with support, as measured by the Hammersmith Infant Neurological Examination, and 83% (34/41) were able to feed orally. 90% (37/41) had a CHOP-INTEND* score increase of at least 4 points, with 56% (23/41) achieving a score above 40; the median increase was 20 points. The median age at enrolment was 5.3 months.

About SUNFISH
In SUNFISH, children and adults treated with Evrysdi experienced a clinically meaningful and statistically significant improvement in motor function at 12 months compared to placebo (1.55 point mean difference; p=0.0156; Evrysdi: 1.36 points [95% CI: 0.61, 2.11]; placebo: -0.19 points [95% CI: -1.22, 0.84]), as measured by the change from baseline in the Motor Function Measure-32 (MFM-32) total score. Children and adults also experienced significant improvement in upper limb function, a key secondary endpoint, at 12 months compared to placebo (1.59 point mean difference; p=0.0469; Evrysdi: 1.61 points [95% CI: 1.00, 2.22]; placebo: 0.02 points [95% CI: -0.83, 0.87]), as measured by the change from baseline in the Revised Upper Limb Module (RULM). The median age at enrolment was nine years. Patients treated with Evrysdi for 2-years overall experienced maintenance of improvement in motor function between month 12 and month 24. The mean change from baseline for MFM32 was 1.83 (95% CI: 0.74, 2.92) and for RULM was 2.79 (95% CI: 1.94, 3.64).
Evrysdi demonstrated a favourable efficacy and safety profile, with the safety profile established across the FIREFISH and SUNFISH trials. The most common adverse events were upper respiratory tract infection, pneumonia, nasopharyngitis, pyrexia, constipation, rhinitis, diarrhoea, headache, cough and vomiting. There were no treatment-related safety findings leading to withdrawal from either study.
About Evrysdi™ (risdiplam)
Evrysdi is a survival motor neuron 2 (SMN2) splicing modifier designed to treat SMA caused by mutations in chromosome 5q that lead to SMN protein deficiency. Evrysdi is administered daily at home in liquid form by mouth or by feeding tube.
Evrysdi is designed to treat SMA by increasing and sustaining the production of the survival motor neuron (SMN) protein. SMN protein is found throughout the body and is critical for maintaining healthy motor neurons and movement.
Evrysdi is currently being evaluated in four multicentre trials in people with SMA:
About SMA
SMA is a severe, progressive neuromuscular disease that can be fatal. It affects approximately one 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.
