A Phase 3, Randomized Double-Blind, Placebo-Controlled Multicenter Study to Evaluate Efficacy and Safety of Repeated Administration of NurOwn® (Autologous Mesenchymal Stem Cells Secreting Neurotrophic Factors) in Participants With ALS


Brief Summary:

This study will evaluate the safety and efficacy of repeated administration of NurOwn®
(MSC-NTF cells) therapy, which is based on transplantation of autologous bone marrow derived
mesenchymal stromal cells (MSC), which are enriched from the patient’s own bone marrow,
propagated ex vivo and induced to secrete Neurotrophic factors (NTFs).

The autologous NurOwn® (MSC-NTF cells) are back-transplanted into the patient intrathecally
by standard lumbar puncture where neurons and glial cells are expected to take up the
neurotrophic factors secreted by the transplanted cells


Inclusion Criteria:

– ALS diagnosed as possible, laboratory-supported probable, probable, or definite as
defined by revised El Escorial criteria.

to a US site for all follow-up study visits

Exclusion Criteria:

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)
