What are the possible benefits and risks of SPINRAZA?

SPINRAZA is the first approved therapy for pediatric and adult patients with SMA.

The effectiveness of SPINRAZA was established in the longest clinical trial program in SMA to date, which included the pivotal ENDEAR and CHERISH clinical trials. The ENDEAR pivotal study studied survival without permanent ventilation in 121 children with early-onset SMA. The CHERISH clinical trial studied changes in motor function in 126 nonambulatory individuals with later-onset SMA.

In clinical studies, the most common side effects of SPINRAZA included lower respiratory infection, fever, constipation, headache, vomiting, back pain, and post-lumbar puncture syndrome (headache related to the intrathecal procedure).

Because an increased risk of bleeding and kidney damage has been seen in similar medications,
individuals taking SPINRAZA may be at similar risk.

It is recommended that your healthcare provider (HCP) perform blood and urine testing once before treatment and again before each dose to monitor for signs of these risks.


How does SPINRAZA work?

SMA is a disease of the central nervous system (CNS), caused by an insufficient amount of SMN protein in motor neurons. SPINRAZA is delivered directly to the CNS, where it increases SMN protein production, targeting an underlying cause of SMA.

How is SPINRAZA given?

SPINRAZA is given as an injection into cerebrospinal fluid (the fluid in the spine) during a medical
procedure called an intrathecal injection, an established route of medication delivery used to target
the CNS.
