Mutations in SOD1 gene can cause #familialALS in a process involving dissociation of the #SOD1 dimer. This study shows that a novel cyclic thiosulfinate cross-linker can stabilize the SOD1 dimer in vivo, with therapeutic implications for fALS #PLOSBiology https://plos.io/3UpT8yL

#FDA just approved Qalsody (tofersen) for #ALS with #SOD1 mutation (~2% of ALS cases), based on a of the #biomarker neurofilament (NFL) in the plasma.
ALS is a progressive neurodegenerative disorder, attacking nerve cells that control voluntary muscles (e.g., breathing)
Qalsody is given intrathecally (in the spine) with 3 initial doses at 14-day intervals and maintenance every 28 days
Most common side effects were pain, fatigue, joint pain, white blood cells in the CSF, and muscle pain
