What is SMA and how does Evrysdi help?

SMA is caused by mutations in the SMN1 gene, which normally produces SMN protein. Without enough SMN protein, motor neurons die and muscles weaken over time. SMA affects about one in 10,000 babies born worldwide and is the leading genetic cause of infant death.

Evrysdi is a SMN2-directed RNA splicing modifier, which means it helps the SMN2 gene produce more functional SMN protein. Evrysdi has been shown to improve motor function and survival in people with SMA across different ages and stages of the disease.

Who can take Evrysdi?

Evrysdi is approved for adults and children two months of age and older with SMA. Evrysdi is not recommended for pregnant or breastfeeding women, as it may harm the unborn or nursing baby. Evrysdi may also affect fertility in men. Before taking Evrysdi, talk to your doctor about your medical conditions, medicines you take, and potential side effects.

How to take Evrysdi?

Evrysdi is a liquid medicine that comes in a bottle with a syringe and an adapter. You should receive Evrysdi from the pharmacy as a liquid. Do not mix or dilute Evrysdi with any other liquid.

Evrysdi is taken once daily at about the same time each day. The dose of Evrysdi is based on your body weight and may change over time as you grow. Your doctor will tell you how much Evrysdi to take and when to start taking it.

You can take Evrysdi by mouth or through a feeding tube. If you take Evrysdi by mouth, use the syringe to measure the dose and squirt it into your mouth or onto a soft food such as applesauce. If you use a feeding tube, use the syringe to measure the dose and push it through the tube. After taking Evrysdi, drink some water or liquid food to make sure all of the medicine is swallowed.

What are the benefits of Evrysdi?

Evrysdi has been proven to improve motor function and survival in people with SMA in clinical trials. The trials included people with different types of SMA, ages, and disease severity.

In one trial, 41% of infants treated with Evrysdi achieved a milestone that they were not able to do before, such as sitting without support, rolling over, or standing with assistance. In another trial, 29% of children treated with Evrysdi improved their motor function score by at least three points after one year, compared to 0% of those who received placebo. In a third trial, 38% of adults treated with Evrysdi maintained their motor function score after one year, compared to 0% of those who received placebo.

Evrysdi also reduced the risk of death or permanent ventilation by 61% in infants and by 81% in children compared to natural history data (data collected from people with SMA who did not receive treatment).

What are the risks of Evrysdi?

Evrysdi may cause serious side effects, including:

  • Low platelet count (thrombocytopenia), which may cause bruising or bleeding more easily
  • Eye problems (ophthalmic toxicity), which may cause blurred vision, sensitivity to light, or eye pain
