NCT02623699 ↗ An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS) Completed Ionis Pharmaceuticals, Inc. Phase 3 2016-01-20 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.
NCT02623699 ↗ An Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of BIIB067 in Adults With Inherited Amyotrophic Lateral Sclerosis (ALS) Completed Biogen Phase 3 2016-01-20 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.
NCT04856982 ↗ A Study of BIIB067 When Initiated in Clinically Presymptomatic Adults With a Confirmed Superoxide Dismutase 1 Mutation Recruiting Biogen Phase 3 2021-05-17 The primary objective of this study is to evaluate the efficacy of BIIB067 when initiated in presymptomatic adult carriers of a superoxide dismutase 1 (SOD1) mutation with elevated neurofilament (NF). The secondary objectives of this study are to evaluate the safety and tolerability of BIIB067 and to evaluate the effect of BIIB067 on pharmacodynamics (PD)/treatment response biomarkers when initiated prior to versus at the time of emergence of clinically manifest amyotrophic lateral sclerosis (ALS).
NCT06391645 ↗ Nerve Growth Factor Encapsulated With 2-methacryloyloxyethyl Phosphorylcholine Nanocapsules in the Treatment of Amyotrophic Lateral Sclerosis NOT_YET_RECRUITING Beijing Healthunion Cardio-Cerebrovascular Disease Prevention and Treatment Foundation PHASE2 2024-05-01 Amyotrophic lateral sclerosis (ALS) is one of the most lethal neurodegenerative diseases, with most patients dying from respiratory failure 3-5 years after the onset. The purpose of this study is to explore the efficacy and safety of nerve growth factor (NGF) encapsulated with 2-methacryloyloxyethyl phosphorylcholine (MPC) nanocapsules in the treatment of ALS patients.
