Phase 2, Randomized, Double Blind, Placebo Controlled Multicenter Study of Autologous MSC-NTF Cells in Patients With ALS

Inclusion Criteria 1. Males and females ages 18 to 75 years old, inclusive. 2. ALS diagnosed as possible, laboratory-supported probable, probable, or definite as defined by revised El Escorial criteria. 3. Disease onset, as defined by first reported occurrence of symptomatic weakness, spasticity, or bulbar symptoms, of more than 12 months and less than or equal to 24 months. 4. Current disease symptoms must include limb weakness. 5. ALSFRS-R ≥30 at the Screening Visit. 6. Upright slow vital capacity (SVC) measure ≥65% of predicted for gender, height, and age at the Screening Visit. 7. Subjects must be taking a stable dose of riluzole for at least 30 days prior to enrolment or not be on riluzole, and not have been on it for at least 30 days prior to enrolment (riluzole-naïve subjects are permitted in the study). 8. Capable of providing informed consent and willing and able to follow study procedures, including willingness to undergo lumbar puncture. 9. Geographic accessibility to the study site and willingness and ability to comply with follow-up. 10. Women of child-bearing potential must agree not to become pregnant for the duration of the study. Women must be willing to consistently use two forms of contraceptive therapy throughout the course of the trial, and undergo a pregnancy test one week before bone marrow aspiration. Men must be willing to consistently use two forms of contraceptive if their partners are of child-bearing age. 11. Citizen or permanent resident of the United States. Exclusion Criteria: 1. Prior stem cell therapy of any kind. 2. Inability to lie flat for the duration of intrathecal cell transplantation and/or bone marrow biopsy, or inability to tolerate study procedures for any other reason. 3. History of autoimmune disease (excluding thyroid disease) myelodysplastic or myeloproliferative disorder, leukemia or lymphoma, whole body irradiation, hip fracture, or severe scoliosis. 4. Any unstable clinically significant medical condition other than ALS (e.g., within six months of baseline, had myocardial infarction, angina pectoris, and/or congestive heart failure), treatment with anticoagulants that, in the opinion of the investigator, would compromise the safety of patients. 5. Any history of malignancy including any malignancy affecting the central nervous system and melanoma, within the previous 5 years, with the exception of localized skin cancers (with no evidence of metastasis, significant invasion, or re-occurrence within three years of baseline). 6. Serum AST or ALT value \>3.0 times the upper normal limit. 7. Serum creatinine value \>2.0 times the upper normal limit. 8. Positive test for Hepatitis B, Hepatitis C, HIV. 9. Current use of immunosuppressant medication or use of such medication within 4 weeks of Screening visit (Visit 1). 10. Any history of acquired or inherited immune deficiency syndrome. 11. Exposure to any other experimental agent (off-label use or investigational) or participation in a clinical trial within 30 days prior to Screening Visit (Visit 1). 12. Use of non-invasive ventilation (NIV), diaphragm pacing system or invasive ventilation (tracheostomy). 13. Any history of either substance abuse within the past year, or unstable psychiatric disease according to PI judgment. 14. Placement or usage of feeding tube. 15. Pregnant women or women currently breastfeeding.
