Brief Summary:
This is a Phase II, single centre, randomized, parallel, double blind, placebo-controlled clinical trial to determine the safety of Withania somnifera in participants with Amyotrophic Lateral Sclerosis (ALS).

Condition or disease Intervention/treatment Phase
ALS Drug: Withania somnifera Drug: Placebo Phase 2

Detailed Description:
There will be up to 75 participants randomized 1:1:1 to receive either high dosage Withania somnifera extract (1088 mg daily), medium dosage Withania somnifera extract (544 mg daily) or matching placebo. The study will consist of a Screening Period, Randomization visit, Baseline visit, and Follow-up visits. The treatment period will be 8 weeks and a final follow up call will occur at Week 9.

Primary Outcome Measures :
  1. Incidence of adverse events (safety) [ Time Frame: From Baseline visit until end of study visit (Week 9) ]
    Incidence of adverse events


Secondary Outcome Measures :
  1. Change in SICI values [ Time Frame: Baseline to 8 weeks ]
    Short-interval intracortical inhibition (SICI) measured by transcranial magnetic stimulation (TMS).

  2. Change in RMT values [ Time Frame: Baseline to 8 weeks ]
    Resting motor threshold (RMT) measured by transcranial magnetic stimulation (TMS).

  3. 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).

  4. 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).


Other Outcome Measures:
  1. 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.

  2. 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.
