Retrospective Study on the Safety and Therapeutic/Improvement Effects of Intravenous Administration of SHED-CM for ALS (SHED-CAH2023)

Amyotrophic Lateral Sclerosis (ALS) is a progressive and irreversible neurodegenerative disease with limited treatment options. Advances in regenerative medicine have opened new avenues for therapeutic interventions. This retrospective cohort study evaluated the safety and efficacy of stem cells from human exfoliated deciduous teeth-conditioned media (SHED-CM) in 24 patients with ALS treated at a single facility between January 1, 2022, and November 30, 2023. Safety assessments included adverse events, vital signs, and laboratory test changes before and after administration, whereas efficacy was measured using the ALS Functional Rating Scale-Revised (ALSFRS-R), grip strength, and forced vital capacity. while ALSFRS-R scores typically decline over time, the progression rate in this cohort was slower, suggesting a potential delay in disease progression. Alternatively, improvements in muscle strength and mobility were observed in some patients. Although adverse events were reported in only 3% of cases (no serious allergic reactions), the treatment-induced changes in vital signs and laboratory results were not clinically significant. The SHED-CM treatment appears to be a safe and potentially effective therapeutic option for patients with ALS. Further research is needed to optimize the SHED-CM treatment; however, this study lays the groundwork for future exploration of regenerative therapies for ALS.
