Important research is ongoing on SMA therapy. The most recently developed Zolgensma is the world’s most expensive drug. The SMA drug nusinersan, which was approved by the FDA in 2016, has been approved for use in our country since 2017. Used in SMA Type 1 cases, this drug helps the SMN gene to secrete protein. Spinraza, which is one of the drugs produced for SMA disease, is injected directly into the cerebrospinal fluid in 4 doses for the first 63 days in babies. Evrysdi, which is used in SMA patients over two months, is given to the patient as a daily dose of syrup.
