For Patients and Caregivers

Evrysdi increases SMN protein production throughout the body1,2

Designed to go everywhere2

Evrysdi is formulated as a small molecule that can cross the blood-brain barrier, allowing it to reach tissues and organs throughout the body that need SMN protein, such as*:

*As observed in animal models.2

How Evrysdi works

Evrysdi is formulated to address the underlying cause of spinal muscular atrophy (SMA)1,2

SMN2 splice-modifying technology increases the production of functional SMN protein in the blood1,2

In SMA, a deletion or mutation in the SMN1 gene leads to a deficit in SMN protein2

The SMN2 gene also produces SMN protein, but not enough to compensate for the mutation2

Evrysdi is a SMN2-splicing modifier that increases the production of full-length SMN protein in the blood1*

*Proposed mechanism of action. In preclinical studies, risdiplam was shown to increase exon 7 inclusion in SMN2 messenger ribonucleic acid (mRNA) transcripts and production of full-length SMN protein in the brain.1

Evrysdi works daily to sustain increased SMN protein levels in the blood1

Treatment with Evrysdi approximately doubled SMN protein levels

SMN protein levels were sustained in the blood throughout the 2-year treatment period, regardless of SMA type, weight, or age*

Important Safety Information and Indication

Indication

EVRYSDI is indicated for the treatment of spinal muscular atrophy (SMA) in pediatric and adult patients.

Interactions with Substrates of MATE Transporters

  • Based on in vitro data, Evrysdi may increase plasma concentrations of drugs eliminated via MATE1 or MATE2-K, such as metformin
  • Avoid coadministration of Evrysdi with MATE (multidrug and toxin extrusion) substrates. If coadministration cannot be avoided, monitor for drug-related toxicities and consider dosage reduction of the coadministered drug if needed

Pregnancy & Breastfeeding

  • Evrysdi may cause embryofetal harm when administered to a pregnant woman. In animal studies, administration of Evrysdi during pregnancy and/or lactation resulted in adverse effects on development. Advise pregnant women of the potential risk to the fetus
  • Pregnancy testing is recommended prior to initiating Evrysdi. Advise female patients to use contraception during treatment with Evrysdi and for at least 1 month after the last dose
  • There is a pregnancy exposure registry that monitors pregnancy and fetal/neonatal/infant outcomes in women exposed to Evrysdi during pregnancy. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves by calling 1-833-760-1098 or visiting https://www.evrysdipregnancyregistry.com.
  • The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Evrysdi and any potential adverse effects on the breastfed infant

Potential Effects on Male Fertility

  • Counsel male patients that fertility may be compromised by treatment with Evrysdi. Male patients may consider sperm preservation prior to treatment

Most Common Adverse Reactions

  • The most common adverse reactions in later-onset SMA (incidence in at least 10% of patients treated with Evrysdi and more frequent 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, adverse reactions with an incidence of at least 10% were upper respiratory tract infection (including nasopharyngitis, rhinitis), lower respiratory tract infection (including pneumonia, bronchitis), constipation, vomiting, and cough
  • The safety profile for presymptomatic patients is consistent with the safety profile for symptomatic SMA patients treated with Evrysdi in clinical trials

You may report side effects to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. You may also report side effects to Genentech at 1-888-835-2555.
