Inclusion Criteria

• Age 18 through 80 years inclusive;
• Geographically accessible to the site and able to come to the site once a week for 24 weeks;
• Definite, probable, probable laboratory supported ALS diagnosis according to the revised El Escorial criteria; 4) Disease duration 6 to 24 months from symptom onset;
• Self sufficiency: Satisfactory bulbar and spinal function (score 3+ on the ALSFRS-R for swallowing, cutting food and handling utensils, and walking); 6) Satisfactory respiratory function (FVC ≥80% of predicted); 7) Documented progression of symptoms in the last three months, as measured by the ALSFRS-R scale; 8) Ability to understand and comply with the study requirements and to give written informed consent personally or via a legally authorized representative; 9) Treatment with riluzole 50 mg twice/day for at least 1 month prior to screening visit.

Self sufficiency: this term reflect independence in daily living activities. It is an intuitive parameter to indicate preservation of key functional activities, and - not least - it has shown to be a valid and reliable measure

Exclusion Criteria

• Motor neuron disease (MND) other than ALS;
• Involvement of systems other than motor possibly determining a functional impairment (as measured by the end-points) for the entire duration of the study;
• Other severe clinical conditions (e.g., cardiovascular disorders, neoplasms) with impact on survival or functional disability in the next 12 months;
• Renal insufficiency as defined by a serum creatinine > 1.5 times the upper limit of normal;
