Evrysdi is designed to address the underlying cause of SMA

People with spinal muscular atrophy (SMA) have low levels of an important protein

Missing SMN icon

SMA is a genetic condition that causes muscles throughout the body to break down.

This happens when the body can’t produce enough of a key protein called “survival motor neuron,” or SMN, which is needed for specialized nerves called motor neurons to function properly.

This happens when the body can’t produce enough of a key protein called “survival motor neuron,” or SMN, which is needed for specialized nerves called motor neurons to function properly.

Evrysdi is designed to help the body make more SMN protein

Within 4 weeks of treatment with Evrysdi, SMN protein levels in the blood more than doubled, and they were maintained for Types 1, 2, and 3 SMA throughout 2 years of the studies*
