Inclusion Criteria:
- ALS diagnosed as possible, laboratory-supported probable, probable, or definite as defined by revised El Escorial criteria.
- Having onset of ALS disease symptoms, including limb weakness within 24 months at the Screening Visit.
- ALSFRS-R ≥ 25 at the screening Visit.

- Rapid progressors - Participants taking a stable dose of Riluzole are permitted in the study - Citizen or permanent resident of the United States or Canadian citizen able to travel to a US site for all follow-up study visits Exclusion Criteria:
- Prior stem cell therapy of any kind - History of autoimmune or other serious disease (including malignancy and immune deficiency) that may confound study results - Current use of immunosuppressant medication or anticoagulants (per Investigator discretion) - Exposure to any other experimental agent or participation in an ALS clinical trial within 30 days prior to Screening Visit - Use of RADICAVA (edaravone injection) within 30 days of screening or intent to use edaravone at any time during the course of the study including the follow up period - Use of non-invasive ventilation (BIPAP), diaphragm pacing system or invasive ventilation (tracheostomy) - Feeding tube - Pregnant women or women currently breastfeeding

Neurotrophic factors (NTFs) are potent survival factors for embryonic, neonatal, and adult neurons and are considered potential therapeutic candidates for ALS. Delivery of multiple NTFs to the immediate environment of afflicted neurons in ALS patients is expected to improve their survival and thus slow down disease progression and alleviate symptoms. NTF-secreting mesenchymal stromal cells (MSC-NTF cells) are a novel cell-therapeutic approach aimed at effectively delivering NTFs directly to the site of damage in ALS patients. Participants meeting the inclusion and exclusion criteria will be randomized and will undergo bone-marrow aspiration. MSC of the participants randomized to the treatment group will be induced into MSC-NTF cells. Participants will undergo a total of three intrathecal (IT) transplantations with NurOwn® (MSC-NTF cells) or matching placebo at three bi-monthly intervals
