SPINRAZA has been studied in the largest clinical trial conducted to date in spinal muscular atrophy (SMA) and evaluated in individuals across a broad range of SMA types and levels of function. Clinical trials enrolled patients aged 3 days to 16 years old and included patients with later-onset SMA.‡
‡Clinical outcomes may vary in patients older than the studied population.
QUESTIONS + ANSWERS
Did motor function improve in people on SPINRAZA with later-onset SMA?
Improvements in motor function were seen over 15 months in CHERISH, a well-controlled clinical study of 126 nonambulatory individuals aged 2 to 9 years old. Motor skills such as sitting, rolling, and arm strength were measured primarily by the Hammersmith Functional Motor Scale—Expanded (HFMSE) and supported by the Revised Upper Limb Module (RULM).
The long-term effects of SPINRAZA were evaluated in the CS2/CS12 study over a 3-year period (1050 days) in 11 individuals with Type 2 and 17 individuals with Type 3 SMA ranging from 2 to 16 years old. CS2/CS12 was an open-label study and all individuals received SPINRAZA. Limitations included differences in dosing compared with the approved regimen and the lack of an untreated group.
Some individuals taking SPINRAZA improved or maintained motor function over nearly 3 years, regardless of their level of function before starting treatment (baseline).

Who is SPINRAZA for?
SPINRAZA is indicated for both adults and children with SMA.
How many adults with SMA have been treated with SPINRAZA?
Over 1200 adults with SMA have been treated with SPINRAZA in the US,* and a total of over 10,000 infants, children, and adults with SMA have been treated with SPINRAZA worldwide, including early access and commercial patients, as well as clinical trial participants (through December 2019).
*Based on commercial patients in the US (including Puerto Rico) through December 2019.
