A Caregiver’s Guide to ZOLGENSMA Indication ZOLGENSMA® (onasemnogene abeparvovec-xioi) is a prescription gene therapy used to treat children less than 2 years old with spinal muscular atrophy (SMA). ZOLGENSMA is given as a one-time infusion into a vein. ZOLGENSMA was not evaluated in patients with advanced SMA. Important Safety Information ZOLGENSMA can cause acute serious liver injury . Liver enzymes could become elevated and may reflect acute serious liver injury in children who receive I’ll always remember the ZOLGENSMA. Patients will receive an oral corticosteroid before and after infusion day we received the with ZOLGENSMA and will undergo regular blood tests to monitor liver function. one-time-only Contact the patient’s doctor immediately if the patient’s skin and/or whites of the eyes appear yellowish, or if the patient misses a dose for SMA dose of the corticosteroid or vomits it up. Please see additional Important Safety Information on page 17 and the Malachi, treated at ~4 months and pictured at 4 years, accompanying Full Prescribing Information. was diagnosed with SMA Type 1. 2 ZOLGENSMA stops the progression of SMA with a one- time-only dose This guide will help you learn more about ZOLGENSMA® (onasemnogene abeparvovec-xioi), a one-time infusion for the treatment of children less than 2 years old with spinal muscular atrophy (SMA). Ask your doctor if ZOLGENSMA is the right choice for your child with SMA. Watch Evelyn’s video Evelyn, treated at ~2 months and pictured at 41/2 years, was diagnosed with SMA Type 1. Important Safety Information Viral respiratory infections before or after ZOLGENSMA infusion can lead to more serious complications. Contact the patient’s doctor immediately if you see signs of a possible viral respiratory infection such as coughing, wheezing, sneezing, runny nose, sore throat, or fever.

As a result, things many of us take for granted, like breathing, eating, speaking, and lifting the head, become difficult.Once motor neuron cells die, they cannot be brought back. SMA affects about 1 in every 11,000 11K babies born each year. Learn more about the cause of SMA *Calculations are based on an estimated US population of 330 million. ∠ Table of contents FACTS ABOUT SMA 5 The role of a backup gene The SMN1 and SMN2 genes There is a backup gene for the SMN1 gene, called the SMN2 gene. People can have 1 or more copies of this Unaffected person sufficient SMN protein backup gene. This gene, like the SMN1 gene, tells the body to make SMN protein. For people with SMA, SMN2 the SMN2 gene is the main source of SMN protein backup production; however, it is unable to produce as much genes protein as the SMN1 gene. That is why it is essential SMN1 to replace the function of the missing or nonworking SMN1 gene. In fact, the SMN2 gene makes only about 10% of working SMN protein compared to the protein produced by the SMN1 gene. Even people with several copies of the SMN2 gene may not produce as much SMN protein Person living with SMA as those with a working SMN1 gene, and their motor less SMN protein neuron cells may not work as they should. Usually, the SMN2 more copies of the SMN2 gene a person has, the less backup severe his or her SMA is. genes SMN1 Learn how SMA progresses without treatment missing or nonworking ∠ Table of contents FACTS ABOUT SMA 6 A mother’s powerful persistence When Maisie was diagnosed with spinal muscular atrophy (SMA) Type 1, her mother, Ciji, knew she would need to become a powerful advocate for her daughter. From the beginning, Ciji wanted her daughter to be treated with ZOLGENSMA® (onasemnogene abeparvovec-xioi). However, when Maisie was diagnosed, ZOLGENSMA was not yet FDA-approved, and she didn’t qualify for the clinical studies. Ciji understood that time is of the essence in SMA, so she started Maisie on an FDA-approved treatment when she was ~6 months old. Despite this, Ciji was still drawn to ZOLGENSMA as a treatment option because it targets the genetic root cause of SMA with one dose. Her determination to advocate for her daughter prevailed Watch Maisie’s video when Maisie was treated with ZOLGENSMA at about 20 months old. At 2 years old, Maisie has achieved mobility milestones, Maisie, treated with ZOLGENSMA at ~20 months and pictured at but for Ciji, the greatest milestone will always be the first 2 years, was diagnosed with SMA Type 1. Maisie started another time Maisie said, “Momma.” SMA treatment when she was ~6 months old but discontinued after receiving ZOLGENSMA. Important Safety Information Thrombotic microangiopathy (TMA) has been reported to occur approximately one week after ZOLGENSMA infusion. Caregivers should seek immediate medical attention if the patient experiences any signs or symptoms of TMA, such as unexpected bruising or bleeding, seizures, or decreased urine output.

ZOLGENSMA is not a cure and cannot reverse damage already caused by SMA before the treatment treatment. of SMA How ZOLGENSMA is given ZOLGENSMA is given as a one-time infusion into a vein over 60 minutes at a treatment center. Important Safety Information Talk with the patient’s doctor to decide if adjustments to the vaccination schedule are needed to accommodate treatment with a corticosteroid. Protection against respiratory syncytial virus (RSV) is recommended.

Important Safety Information Temporarily, small amounts of ZOLGENSMA may be found in the patient’s stool. Use good hand hygiene when coming into direct contact with bodily waste for 1 month after infusion with ZOLGENSMA. Disposable diapers should be sealed in disposable trash bags and thrown out with regular trash.
