abstract = {Tofersen is the first effective and approved therapy for
superoxide dismutase 1 (SOD1)-associated amyotrophic lateral
sclerosis (ALS [SOD1-ALS]). Following treatment with
tofersen, neurofilament levels in patients' cerebrospinal
fluid (CSF) and serum seem to respond earlier than clinical
parameters. This evidence prompted us to hypothesize that
this novel treatment could provide an opportunity to
identify additional biomarkers responsive to therapy in
SOD1-ALS.We investigated a panel of 120 neural, glial, and
inflammatory markers in CSF and serum samples longitudinally
collected from a total of 28 SOD1-ALS patients at baseline,
and after 3, 6 and 12 months of treatment with tofersen,
followed by validation with conventional methodology.We
identified a set of proteins, including neurofilament light
chain, neurofilament heavy chain, amyloid-beta 1-40 and
amyloid-beta 1-42, neuropeptide Y (NPY), and ubiquitin
C-terminal hydrolase L1 (UCHL1), whose CSF levels both
differed between SOD1-ALS and the control group, and were
responsive to tofersen at 3 and 6 months after treatment
initiation. Another group of markers, including the
neuropentraxin (NPTX) family members NPTX1, NPTX2 and NPTXR,
did not separate untreated SOD1-ALS from controls, but was
responsive to tofersen. At 12 months on tofersen the levels
of neurofilament light chain, neurofilament heavy chain,
NPTX1, NPTX2, and NPTXR remained reduced compared with
baseline, and correlated with the clinical response to
tofersen. Consistent with increasing CSF pleocytosis and
intrathecal immunoglobulin production, inflammatory markers
were significantly increased after 12 months of
treatment.Our results highlight a complex, time-dependent
differential response of CSF biomarkers to tofersen
treatment, and may pave the way for developing a panel of
responsive proteins to make biomarker endpoints more robust
in clinical trials for SOD1-ALS and beyond. ANN NEUROL
