This is a 48-week, randomised, multi-centre, double-blind, placebo-controlled, parallel group investigation of the efficacy and safety of intravenous (IV) ozanezumab (GSK1223249) compared to placebo in subjects with Amyotrophic Lateral Sclerosis (ALS). Following a screening period of up to four weeks, eligible subjects will be randomised (1:1) to receive IV placebo or 15 milligram (mg)/ kilogram (kg) IV ozanezumab every 2 weeks for a period of 48 weeks with a follow-up visit around 14 weeks after the last infusion. A total of approximately 294 eligible subjects will be randomised from approximately 37 centers worldwide. The primary objective is to assess the effect of ozanezumab on the physical function and survival of ALS subjects over a treatment period of 48 weeks. Function will be measured using the ALS Functional Rating Scale - Revised (ALSFRS-R). Secondary objectives include the evaluation of other clinical outcomes associated with ALS (respiratory function, muscle strength, progression free survival and overall survival) in support of the primary objective. Quality of life, safety, tolerability, immunogenicity and pharmacokinetics (ozanezumab and riluzole) will also be assessed.

Primary Outcome Measures:
  • To assess the effect of ozanezumab on the function and survival of ALS patients [ Time Frame: Over 48 weeks ]
    The effect of ozanezumab on the function and survival of ALS patients will be measured by the joint rank scores for combined analysis of function and survival measured by the ALS Functional Rating Scale-Revised (ALSFRS-R) over 48-weeks.

Secondary Outcome Measures:
  • Change from Baseline in amyotrophic lateral sclerosis functional rating scale-revised (ALSFRS R) [ Time Frame: Week 48 ]
  • Change from Baseline in Slow Vital Capacity (SVC) [ Time Frame: Week 48 ]
  • Change from Baseline in Muscle Strength as measured by Hand Held Dynamometry (HDD) [ Time Frame: Week 48 ]
  • Proportion of Clinical Global Impression - Improvement Scale (CGI-I) responders at Week 48 [ Time Frame: Week 48 ]
  • Overall Survival (at Week 48 and Week 60) [ Time Frame: Up to Week 48 and up to Week 60 ]
    Defined as time from randomisation to death or censored at Week 48 / Week 60 whichever comes first

  • Progression-free Survival [ Time Frame: Up to Week 48 ]
    Defined as time from randomisation to progression or death or censored at Week 48 whichever comes first

  • Change from Baseline to Week 48 in EuroQol-Short form (EQ 5D-L) [ Time Frame: Week 48 ]
  • Change from Baseline to Week 48 in amyotrophic lateral sclerosis assessment questionnaire-40 (ALSAQ 40) [ Time Frame: Week 48 ]
  • Incidence and severity of adverse events (AEs) [ Time Frame: Throughout the study (screening upto follow-up) ]
    Number of subjects with incidence of AEs

  • Change from Baseline in vital signs (systolic blood pressure, diastolic blood pressure and heart rate) and weight [ Time Frame: up to Week 60 ]
  • Change from Baseline in routine laboratory tests [ Time Frame: up to Week 60 ]
  • Change from Baseline in electrocardiogram (ECG) parameters [ Time Frame: up to Week 60 ]
  • Plasma PK parameters at steady state [ Time Frame: W0, W2 (only part A), W4, W8, W12, W24, W36, W44, W48, W60 ]
    Estimates of individual ozanezumab PK parameters, including AUC(0-tau)ss, Cavgss, will be listed and summarized

  • Plasma concentrations of riluzole [ Time Frame: W0, W2 (only part A), W4, W8, W12, W24, W36, W44, W48, W60 ]
  • To assess the immunogenicity of IV ozanezumab [ Time Frame: W0, W12, W24, W36, W48 and Follow-up (W>=60) ]
    Incidence of anti-ozanezumab antibodies and relationship to trough concentration in serum will be measured

  • Rate of decline over 48 weeks in amyotrophic lateral sclerosis functional rating scale-revised (ALSFRS R) total score [ Time Frame: Week 48 ]

Inclusion Criteria:

  • Onset of muscle weakness no more than 30 months before screening visit.
  • Slow Vital Capacity (SVC) of at least 65% predicted for gender, age, ethnicity and height at Screening.
  • If on riluzole, the dose must have been stable for at least 28 days prior to Baseline visit.

Exclusion Criteria:

  • Patients with other neuromuscular disorders (including a history of polio) which in the opinion of the investigator could have contributed to the muscular atrophy or weakness caused by ALS
  • Patients with primary lateral sclerosis, monomelic ALS, ALS Parkinsonism dementia complex.

  • Subjects who have participated in a clinical trial involving receipt of a biopharmaceutical product within 6 months prior to the first dosing day.
  • Exposure to non-biological experimental agents 1 month or 5 half-lives prior to Baseline visit (whichever is longer).
