Summary

The primary objectives of Parts A and B of this study are to evaluate the safety, tolerability, and pharmacokinetics (PK) of ascending doses of BIIB067 (tofersen) in adults with ALS and a documented superoxide dismutase 1 (SOD1) mutation. The primary objective of Part C of this study is to evaluate the clinical efficacy of BIIB067 administered to adults with ALS and a confirmed SOD1 mutation. The secondary objective of Parts A and B of this study is to evaluate the effects of BIIB067 on levels of total SOD1 protein in the cerebrospinal fluid (CSF). The secondary objectives of Part C are to evaluate the safety, tolerability, pharmacodynamic (PD), and biomarker effects of BIIB067.
