The study is an open-label, unmasked, uncontrolled phase I and II trial to evaluate safety and efficacy of two injections of autologous mesenchymal stem cells (MSC) in Amyotrophic Lateral Sclerosis (ALS) patients. Patients will be recruited trough a web-based registration system, open for all ALS Brazilian patients. The patients will be enrolled after in-person screening at the University of Sao Paulo Medical School Clinics Hospital and inclusion criteria fulfilled. There will be 9 national calls for registration, two months apart each. The enrolled patients will be followed for 3 months before bone marrow aspiration (BMA). Patients will receive 2 intrathecal MSC injections, 1 and 2 months after BMA. The patients will be followed for 6 months after the interventions.
The study aims to evaluate primarily safety of two injections of autologous mesenchymal stem cells in Amyotrophic Lateral Sclerosis patients. Secondary outcomes of efficacy will also be evaluated
