Qalsody or Tofersen is the first FDA-approved treatment for patients with ALS (amyotrophic lateral sclerosis) associated with a specific mutation in SOD1, targeting neurodegeneration and its progression.
Tofersen
Qalsody or Tofersen is indicated for the treatment of amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene. It is an antisense oligonucleotide that binds to SOD1 mRNA, and thus degrades SOD1 protein and reduces its synthesis by binding to it. Thus, it reduces associated neurodegeneration and its progression. Approved under accelerated approval, Qalsody demonstrated reduction in plasma neurofilament light (NfL), a blood biomarker of neuronal injury, and some studies suggest a slowing of functional decline and preservation of function.
DOSAGE:
Administer Tofersen intrathecally using a lumbar puncture by, or under the direction of, healthcare professionals experienced in performing lumbar punctures. The recommended dosage is 100 mg (15 mL) of Tofersen per administration. Initiate Tofersen treatment with three (3) loading doses administered at 14-day intervals. Administer a maintenance dose every 28 days thereafter.
For missed dose: If the second loading dose is missed, administer Tofersen as soon as possible, and administer the third loading dose 14 days later. If the third loading dose or a maintenance dose is missed, administer Tofersen as soon as possible, and administer the next dose 28 days later.
STRENGTH
Injection: 100 mg/15 mL (6.7 mg/mL) solution in a single-dose vial.

-
Papilledema and Elevated Intracranial Pressure
In clinical studies, 4 patients developed elevated intracranial pressure and/or papilledema.
-
Aseptic Meningitis
1 patient experienced a serious chemical meningitis, resulting in discontinuation of Qalsody. 1 patient experienced aseptic meningitis, which did not lead to discontinuation of Qalsody. Other reported cases of serious reactions include increase in CSF white blood cell and CSF protein.
Monitor for symptoms; diagnostic workup and treatment should be initiated according to the standard of care. Management may require interruption or discontinuation of Tofersen.
