A Compassionate Use Study to Administer NurOwn® (Autologous Mesenchymal Stem Cells Secreting Neurotrophic Factors) to Treat Amyotrophic Lateral Sclerosis (ALS)


About this study

The purpose of this study is to provide up to three intrathecal injections of NurOwn® (MSC-NTF cells, autologous Mesenchymal Stem Cells [MSC] Secreting Neurotrophic Factors [NTF]) given two months apart to patients who have completed all scheduled treatments and follow-up assessments in the BCT-002-US clinical trial. A bone marrow aspiration will be required as part of this program. It will take about 30 weeks for participants to complete the program.
