INTRODUCTION: There are a few therapeutic approaches for Amyotrophic Lateral Sclerosis (ALS) which can only slow down or stop the disease progression for a limited period of time. Since it has been proven that Mesenchymal Stromal Cells (MSCs) produce neurotrophic factors and have some neuroprotective effects, stem cell therapy has been proposed as an alternative or add-on treatment for ALS patients.
METHOD & MATERIAL: In this open-label clinical trial, two-repeated dose of 60 million GMP compliant Wharton's Jelly-derived Mesenchymal Stromal Cells (WJ-MSCs) were transplanted intrathecally (#6 patients) or intravenously (#6 patients) twice with a 3-month interval.
RESULTS: No adverse events related to the intervention or injected cells were reported. While no significant improvement in the total revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R) score or overall clinical efficacy was achieved, patients reported improvements in specific sub-items such as salivation, swallowing, and their speech. Additionally, reductions in muscle tremors and fasciculations, as well as increased muscle strength were observed.
CONCLUSION: In conclusion, using WJ-MSCs is safe and feasible in ALS patients, but the efficacy of these cells should be assessed in future studies with more patients, different routes of cell administration, and maybe with higher doses of the injected cells.
