- Change from baseline in ALSFRS-R score at Month 12 (or last measurement before death in case of censoring) and survival time. [ Time Frame: 12 months ]The amyotrophic lateral sclerosis functional rating scale-revised, or ALSFRS-R, measures the functional status of subjects with ALS. It is based on 12 items, each of which is rated on a 5-point scale (0 to 4). The rate of total functional disability thus ranges from 0 (maximum disability) to 48 (normal function) points.
- Mean change from baseline of muscle strength measured by hand-held dynamometry [ Time Frame: Baseline, Treatment Phase Week 6, Months 3, 6, 9 and12 time points. ]Hand-held dynamometry, or HHD, is used to measure the force generated by each muscle. The scale ranges from 0 (no visible movement of the part) to 10 (holds test position against strong pressure). Thus, the higher the total score, the higher muscle strength is observed.
- Mean change from baseline on quality of life assessed by ALSAQ-5 at Month 12 [ Time Frame: 12 months ]The Amyotrophic Lateral Sclerosis Assessment Questionnaire, or ALSAQ-5, is a patient self-report questionnaire specifically designed to measure 5 areas of health: physical mobility, activities of daily living and independence, eating and drinking, communication and emotional functioning. The subject is asked about 5 different areas of difficulties in their daily lives: ability to stand up, use of limbs, consuming solid food, level of speech coherence, and degree of hope about the future.Each question provides 5 choices from which to choose: Never, Rarely, Sometimes, Often, and Always or cannot do at all.
- Mean change from baseline of functional activity measured by ALSFRS-R at Month 12 [ Time Frame: 12 months ]The ALSFRS-R assessment tool measures the functional status of subjects with ALS. It is based on 12 items, each of which is rated on a 5-point scale (0 to 4). The rate of total functional disability thus ranges from 0 (maximum disability) to 48 (normal function) points. In this context, the ALSFRS-R total score change (lower, same, higher) is documented.
- Responders, measured in percent of subjects overall, whose ALSFRS-R total score was stable or improved [ Time Frame: 12 months ]Proportion of subjects in which ALSFRS-R total score was stable or improved.
- Time to survival [ Time Frame: 12 months ]Defined by death or permanent dependency to ventilator or tracheostomy.
- Number of Participants with Treatment-Related Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: 12 months ]The incidence of treatment-emergent adverse events (TEAEs), severity (mild, moderate, severe), as well as relationship to study treatment (not related, possibly related, probably related) and whether they are considered serious.
- Changes from Baseline in Laboratory Values [ Time Frame: 12 months ]Incidence of out-of-normal-range values and markedly abnormal change from baseline in laboratory safety test variables by treatment group.
