Designed to target the genetic root cause of SMA

ZOLGENSMA is designed to target the genetic root cause of SMA with a one-time-only dose by replacing the function of the missing or nonworking survival motor neuron 1 (SMN1) gene.

The new gene tells motor neuron cells to produce more survival motor neuron (SMN) protein. Motor neuron cells need SMN protein to survive and support muscle functions.

Time is of the essence

With each day that passes without treatment, motor neuron cells become weak and eventually lose all function and die. As a result, things like breathing, eating, swallowing, and speaking become difficult to impossible. Once these cells stop working, the condition is likely to become life threatening.

ZOLGENSMA is designed to deliver a new, working copy of the SMN gene to produce SMN protein, which preserves motor neuron cells throughout the body. In turn, ZOLGENSMA stops the progression of SMA and sustains the remaining muscle function needed for children to survive. The earlier treatment with ZOLGENSMA is given, the sooner muscle function may be preserved. ZOLGENSMA is not a cure and cannot reverse the damage already caused by SMA before treatment.

After treatment with ZOLGENSMA, we saw Brady again. He eats on his own, uses utensils and he eats everything by mouth.

The efficacy and safety of ZOLGENSMA have been established in clinical studies

ZOLGENSMA has been evaluated in clinical studies and continues to be evaluated in long-term follow-up. The purpose of these clinical studies is to evaluate the safety and efficacy of ZOLGENSMA.

The studies are also evaluating how ZOLGENSMA may help patients achieve important milestones like breathing, eating, speaking, and sitting up without support.

What is natural history?

Natural history of SMA refers to the progression of a disease in a person over time without treatment.

Important Safety Information

What is the most important information I should know about ZOLGENSMA?

  • ZOLGENSMA can increase liver enzyme levels and cause acute serious liver injury or acute liver failure.
  • Patients will receive an oral corticosteroid before and after infusion with ZOLGENSMA and will undergo regular blood tests to monitor liver function.

Important Safety Information

What is the most important information I should know about ZOLGENSMA?

  • ZOLGENSMA can increase liver enzyme levels and cause acute serious liver injury or acute liver failure.
  • Patients will receive an oral corticosteroid before and after infusion with ZOLGENSMA and will undergo regular blood tests to monitor liver function.
  • Contact the patient’s doctor immediately if the patient’s skin and/or whites of the eyes appear yellowish, if the patient misses a dose of corticosteroid or vomits it up, or if the patient experiences a decrease in alertness.

What should I watch for before and after infusion with ZOLGENSMA?

  • Infections before or after ZOLGENSMA infusion can lead to more serious complications. Contact the patient’s doctor immediately if you see any signs of a possible infection such as coughing, wheezing, sneezing, runny nose, sore throat, or fever.
  • Decreased platelet counts could occur following infusion with ZOLGENSMA. Seek immediate medical attention if the patient experiences unexpected bleeding or bruising.
  • 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.

What do I need to know about vaccinations and ZOLGENSMA?

  • 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.

Do I need to take precautions with the patient’s bodily waste?

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.

What are the possible or likely side effects of ZOLGENSMA?

The most common side effects that occurred in patients treated with ZOLGENSMA were elevated liver enzymes and vomiting.

Indication

What is ZOLGENSMA?
ZOLGENSMA 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.

The safety information provided here is not comprehensive. Talk to the patient’s doctor about any side effects that bother the patient or that don’t go away.

You are encouraged to report suspected side effects by contacting the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch, or Novartis Gene Therapies, Inc. at 833-828-3947.
