Current Primary Outcome Measures  ICMJE
 (submitted: September 2, 2021)
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to Week 364 ]
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, life-threatening event, requires inpatient hospitalization, significant disability/incapacity or congenital anomaly.
Original Primary Outcome Measures  ICMJE
 (submitted: February 28, 2017)
  • Number of participants experiencing AEs and serious adverse events (SAEs) [ Time Frame: Up to 15 months ]
  • Number of participants with clinically significant laboratory assessment abnormalities [ Time Frame: Up to 15 months ]
  • Number of participants with clinically significant vital sign abnormalities [ Time Frame: Up to 15 months ]
  • Number of participants with clinically significant physical examination abnormalities [ Time Frame: Up to 15 months ]
  • Number of participants with clinically significant neurological examination abnormalities [ Time Frame: Up to 15 months ]
  • Number of participants with clinically significant 12-lead electrocardiograms (ECGs) abnormalities [ Time Frame: Up to 15 months ]
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: September 2, 2021)
  • Levels of BIIB067 in Plasma [ Time Frame: Up to Week 364 ]
  • Levels of BIIB067 in Cerebrospinal Fluid (CSF) [ Time Frame: Up to Week 360 ]
  • Change from Baseline in Total SOD1 Protein in CSF [ Time Frame: Baseline to Week 360 ]
  • Change from Baseline in Neurofilament Light Chain (NfL) Concentration in Plasma [ Time Frame: Baseline to Week 364 ]
  • Change from Baseline in Total ALS Functional Rating Scale - Revised (ALSFRS-R) Score [ Time Frame: Baseline to Week 364 ]
    The ALSFRS-R measures 4 functional domains, including respiratory, bulbar function, gross motor skills, and fine motor skills. There are 12 questions, each scored from 0 to 4, for a total possible score of 48, with higher scores representing better function.
  • Change from Baseline in Slow Vital Capacity (SVC) [ Time Frame: Baseline to Week 364 ]
    Vital capacity will be measured by means of an SVC test, administered in the upright position. Upright SVC will be determined by performing 3 to 5 measures, in accordance with criteria established by the American Thoracic Society and the European Respiratory Society.
  • Change from Baseline in Handheld Dynamometry (HHD) Megascore and Individual Muscle Strength [ Time Frame: Baseline to Week 364 ]
    Quantitative muscle strength will be evaluated using HHD, which tests isometric strength of multiple muscles using standard participant positioning. Approximately 8 muscle groups will be examined (per each side) in both upper and lower extremities.
  • Time to Death or Permanent Ventilation [ Time Frame: Up to Week 364 ]
    Time to death or permanent ventilation is defined as the time to the earliest occurrence of one of the following events: Death; Permanent ventilation [≥22 hours of mechanical ventilation (invasive or noninvasive) per day for ≥21 consecutive days].
  • Time to Death [ Time Frame: Up to Week 364 ]
Original Secondary Outcome Measures  ICMJE
 (submitted: February 28, 2017)
  • PK Parameter of BIIB067 in Plasma: Maximum Observed Concentration (Cmax) [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in cerebrospinal fluid (CSF): Cmax [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in plasma: Time to reach the maximum observed concentration (Tmax) [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in CSF: Tmax [ Time Frame: Up to 15 months ]
  • PK Parameter of BIIB067 in Plasma: Area Under the Concentration-Time Curve from Time 0 to Infinity (AUCinf) [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in CSF: AUCinf [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in plasma: Area under the concentration-time curve from time 0 to time of the last measurable (AUClast) [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in CSF: AUClast [ Time Frame: Up to 15 months ]
  • PK Parameter of BIIB067 in Plasma: Apparent Terminal Elimination Half-Life (t½) [ Time Frame: Up to 15 months ]
  • PK parameter of BIIB067 in CSF: t½ [ Time Frame: Up to 15 months ]

Brief Title  ICMJE Long-Term Evaluation of BIIB067
Official Title  ICMJE An Extension Study to Assess the Long-Term Safety, Tolerability, Pharmacokinetics, and Effect on Disease Progression of BIIB067 Administered to Previously Treated Adults With Amyotrophic Lateral Sclerosis Caused by Superoxide Dismutase 1 Mutation
Brief Summary The primary objective of the study is to evaluate the long-term safety and tolerability of BIIB067 in participants with amyotrophic lateral sclerosis (ALS) and confirmed superoxide dismutase 1 (SOD1) mutation. The secondary objectives are to evaluate the pharmacokinetic (PK), pharmacodynamic (PD), biomarker effects, and efficacy of BIIB067 administered to participants with ALS and a confirmed SOD1 mutation.

  • Presence of an implanted shunt for the drainage of CSF or an implanted central nervous system (CNS) catheter.
  • Prior or current treatment with small interfering ribonucleic acid (RNA), stem cell therapy, or gene therapy.
  • Treatment with another investigational drug, biological agent (excluding BIIB067), or device within 1 month or 5 half-lives of study agent, whichever is longer.
  • Current or anticipated need, in the opinion of the Investigator, of a diaphragm pacing system (DPS) during the study period.
