Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Combined Assessment of Function and Survival (CAFS) [ Time Frame: Week 52 ]
    Efficacy


Secondary Outcome Measures :
  1. Incidence and severity of treatment-emergent adverse events (TEAEs) [ Time Frame: Up to Week 104 ]
    Safety

  2. Number of participants with positive responses (yes) to the Columbia Suicide Severity Rating Scale (C-SSRS) [ Time Frame: Up to Week 104 ]
  3. Change from Baseline in the Revised ALS Functional Rating scale (ALSFRS-R) score [ Time Frame: Baseline, Week 52 ]
    Minimum score of 0 and maximum of 48, with higher values representing better function

  4. Change from Baseline in percentage of slow vital capacity (%SVC) [ Time Frame: Baseline, at Week 52 ]
  5. Change from Baseline in muscle strength [ Time Frame: Baseline, Week 52 ]
  6. Time to death, permanent tracheostomy, or permanent assisted ventilation [ Time Frame: Up to Week 52 ]

  • Sporadic ALS diagnosed as definite, probable, or laboratory-supported probable as defined by the revised El Escorial criteria
  • Slow vital capacity (SVC) ≥60% of the predicted value at screening
  • Onset of ALS symptoms within 72 weeks (18 months) prior to screening
  • Total ALSFRS-R score of ≥30 at screening

  • Significant pulmonary disorder not attributed to ALS (eg, chronic obstructive pulmonary disease, pulmonary fibrosis, cystic fibrosis, pulmonary arterial hypertension)
  • If taking riluzole, participant must be on a stable dose for 30 days prior to the start of the screening period. Use of riluzole is not required for participation.
  • If taking edaravone, participant must be on a stable dose for 60 days prior to the start of the screening period. Use of edaravone is not required for participation.
  • Participation in any other investigational drug trial or exposure to other investigational agent, device, or procedure within 30 days or within 5-half lives of the treatment (whichever is longer) prior to the start of the screening period or during study participation
  • Use of any other complement inhibitor within 30 days or within 5-half lives of the treatment (whichever is longer) prior to the start of the screening period or during study participation
