Some things get everywhere
In SMA Treatment, that’s what you want.
Evrysdi is an oral, non-invasive treatment designed to reach parts of the body that need SMN protein, such as the brain and spinal cord, muscles, larynx, GI system and heart.
Evrysdi gives you more choices in how you treat SMA.
See if Evrysdi is right for you.
Evrysdi is a prescription medicine used to treat spinal muscular atrophy (SMA) in children and adults. Evrysdi works by targeting and modifying the SMN2 gene, allowing the body to produce more survival motor neuron (SMN) protein. This helps to slow down the progression of SMA and improve motor function.
Evrysdi comes in two oral, non-invasive forms, liquid and tablet. It is a daily medication that can be taken at home, at work, or on-the-go.* The recommended dosage of Evrysdi is determined by age and body weight.
*If refrigeration is not available, Evrysdi liquid can be kept at room temperature up to 104°F (40°C) for a combined total of 5 days. Please refer to the Instructions for Use for additional information about storage and administration.
The most common side effects of Evrysdi in adults and children with later-onset SMA include fever, diarrhea, and rash. The most common side effects in infants with infantile-onset SMA include fever, diarrhea, rash, runny nose, sneezing, sore throat, constipation, vomiting, and cough. These are not all the possible side effects of Evrysdi.
The safety profile of presymptomatic infants is consistent with the safety profile for symptomatic SMA patients treated with Evrysdi in clinical studies.

Atrophy
The medical term for getting smaller, which is generally what happens to muscles when they are not stimulated by nerve cells.
BSID-III
Stands for the Bayley Scales of Infant and Toddler Development–Third Edition, which is a tool used to assess a range of physical abilities, such as sitting, rolling, and crawling.
CI
Stands for confidence interval, which shows how much a clinical result is likely to vary.
DMT
Stands for disease-modifying treatment, which in the case of SMA, stimulates production of SMN2 protein.
FDA
Stands for Food and Drug Administration.
G-tube
Stands for gastrostomy tube, which is a tube inserted through the belly that brings nutrition directly to the stomach.
Gene
The basic unit of heredity passed from parent to child, made up of sequences of DNA (deoxyribonucleic acid). They contain information that leads to the development of physical traits such as hair color.
GI system
Stands for gastrointestinal system, also called the digestive system, which refers to the group of organs that take in food and liquids and break them down into energy the body can use.
HINE-2
Stands for Hammersmith Infant Neurological Examination–Module 2, which is a tool used to assess 8 developmental milestones for infants, including head control, sitting, voluntary grasp, ability to kick, rolling, crawling, standing, and walking.
Investigational
Term used to describe medical treatments that are currently being studied in clinical trials to determine how well they work and how safe they are to take.
Larynx
Also known as the voice box, is a hollow tube in the middle of the neck, above the windpipe and esophagus. The larynx allows you to breathe and make sounds.
MFM-32
Stands for Motor Function Measure-32 Items, which is a tool designed to capture changes in head, trunk, and limb motor movements using 32 elements in a broad range of people, including those who cannot walk. It uses 3 main categories: standing/transfer movements, upper/lower body movements, and hand/foot movements.
Molecule
The smallest particle of a substance, made up of one or more atoms.
NG-tube
Stands for nasogastric tube, which is a thin, soft tube that goes in through the nose, down the throat, and into the stomach to provide nutrition or medicine to those who cannot consume by mouth.
Non-invasive
Term used to describe medicines or medical procedures that do not require inserting anything (such as a needle) through the skin or into a body opening.
Oral
Refers to anything having to do with the mouth.
PAL
Stands for Partnership and Access Liaison.
Presymptomatic
When someone has not yet displayed any symptoms but may have underlying presence of the disease, as shown through testing or other means.
Previously treated
When someone has taken either an approved or investigational medication specifically for SMA in the past.
Progression
When the symptoms of SMA get worse over time.
Progressive disease
Any condition that gets worse over time instead of improving.
Protein
Large, complex molecules that play many important roles in the body, including making up the structure of cells and ensuring proper function of tissues and organs.
RULM
Stands for Revised Upper Limb Module, which is a tool specifically designed for people 2.5 years and older living with SMA to evaluate strength in arm movements and the ability to perform certain tasks. It includes tests, such as picking up objects, like coins/tokens, tearing paper, raising a cup to the mouth, and opening a plastic container.
Scoliosis
A sideways curve of the spine. Instead of appearing straight, the spine of a person with scoliosis will have an abnormal S or C shape that leads to their hips or shoulders appearing uneven.
Sedation
A state of calmness, relaxation, or sleepiness as a result of medications called sedatives. Sedation can be used to help you relax or fall asleep for a medical procedure.
SMA
Stands for spinal muscular atrophy, which is a genetic disease affecting the central nervous system, peripheral nervous system, and voluntary muscle movement.
SMN
Stands for survival motor neuron, which is a type of protein that your muscles need to function.
Spinal cord
A tube of tissue that runs from your brain down to your lower back and acts as an important part of your nervous system. The spinal cord carries nerve signals from your brain to the rest of your body, which allow you to feel sensations such as pressure or pain.
Type 1 SMA
SMA symptoms that are present at 6 months of age or earlier. This is sometimes called “infantile onset.” Type 1 SMA is characterized by generalized muscle weakness, a weak cry, and muscle distress, often accompanied by failure to meet developmental milestones such as sitting up unassisted.
Type 2 SMA
SMA symptoms that appear between the ages of 6 to 18 months. People with Type 2 SMA cannot stand or walk without help, but they can sit without support.
Type 3 SMA
SMA symptoms that appear after 18 months of age. People with Type 3 SMA can walk independently but may have difficulty doing so or performing other movements such as running, rising from a chair, or climbing stairs.
