Placebo Comparator |
- Incidence of adverse events (safety) [ Time Frame: From Baseline visit until end of study visit (Week 9) ]Incidence of adverse events
- Change in SICI values [ Time Frame: Baseline to 8 weeks ]Short-interval intracortical inhibition (SICI) measured by transcranial magnetic stimulation (TMS).
- Change in RMT values [ Time Frame: Baseline to 8 weeks ]Resting motor threshold (RMT) measured by transcranial magnetic stimulation (TMS).
- Change in recovery cycle [ Time Frame: Baseline to 8 weeks ]This is a lower motor neuron excitability parameter measured by threshold tracking nerve excitability testing (NET).
- Change in strength duration time constant [ Time Frame: Baseline to 8 weeks ]This is a lower motor neuron excitability parameter measured by threshold tracking nerve excitability testing (NET).
- Incident cases of ALSFRS-R score changes of 4 or more points [ Time Frame: Baseline to 9 weeks ]Any incident case of ≥ 4-point increase in the ALS Functional Rating Scale-Revised (ALSFRS-R) scores or significant clinical improvement at week 8 will be reported. Changes in pro-inflammatory tests (CRP and IL-6) from baseline to Week 8 will be assessed.
- Change in serum IL-6 levels [ Time Frame: Baseline to 8 weeks ]Serum IL-6 levels will serve as an indirect marker of NF-kB inhibition and target engagement.
