Background: AstroRx® is an allogeneic cell therapy, composed of healthy and functional human astrocytes derived from pluripotent embryonic stem cells. An intrathecal injection of a fresh formulation of AstroRx® cells for the treatment of Amyotrophic Lateral Sclerosis (ALS) was evaluated in an early-phase I/IIa clinical trial. The results of this study indicated that the treatment is safe and showed a signal of a clinical benefit in attenuating ALS progression. Due to the logistical challenges associated with the manufacturing and distribution of a fresh cell product and to allow completion of safety and quality control testing before cell administration, a cryopreserved formulation of AstroRx® was developed. The cryopreseved AstroRx® product includes 3.5% DMSO as a cryoprotectant. Upon thawing at the clinical.. View More»
