Design outcomes

Primary

MeasureTime frame
Main Objective: Primary objective is to evaluate the effect of RT001 on the ALSFRS-R in subjects with ALS. ;Secondary Objective: Secondary Objectives: • To evaluate the effect of RT001 on ALS clinical outcomes • To evaluate the effect of RT001 on various functional assessments, pulmonary functional assessments and motor assessments • To assess the long-term safety and tolerability of RT001 ;Primary end point(s): Primary endpoints: Change from baseline in the ALSFRS-R total score at 24 weeks of the double-blind treatment period ;Timepoint(s) of evaluation of this end point: 24 weeks (Day 168) of the double-blind treatment period

Secondary

MeasureTime frame
Secondary end point(s): Secondary endpoints are: - Time to Death or a Specified State of Disease Progression (composite of death, loss of independent ambulation, decline of ALSFRS-R from baseline of more than 6 points, loss of upper arm function, need for tracheostomy, use of respirator, or use of tube feeding) - Change from Baseline in ALS Assessment Questionnaire (40 Items) (ALSAQ40) - Change from baseline in SVC Exploratory endpoints Double-blind part of the study: - Change from Baseline in the Clinical Global Impression of Change (CGI-C) scale - Change from Baseline in the Clinical Global Impression of Severity (CGI-S) - Change from Baseline in evaluation of upper- and lower-limb muscle strength using hand-held dynamometry (HHD) Open-label part of the study: Change from baseline in ALSFRS-R at 24 weeks of the extension treatmen period Safety endpoints - Safety will be evaluated by AEs, physical examination results, vital signs, ECG findings, and clinical laboratory test results. All descriptive statistics will be presented by treatment group. ;Timepoint(s) of evaluation of this end point: 24 weeks (Day 168) 24 weeks (Day 168) of the double-blind treatment period and at 24 weeks of the extension treatment period
