These results indicate that HK532-IGF-1 transplantation can impact learning and memory deficits, as well as Alzheimer’s pathology. The researchers found the results to be encouraging and recommend further study. HK532-IGF-1, Neuralstem’s second stem cell line, is a proprietary line of cortical neural stem cells engineered to express insulin-like growth factor-1 (IGF-1), which has been shown to have wide-ranging neuroprotective properties.
Neuralstem’s patented technology enables the commercial-scale production of multiple types of central nervous system stem cells, which are under development for the potential treatment of central nervous system diseases and conditions.
Neuralstem’s ability to generate human neural stem cell lines for chemical screening has led to the discovery and patenting of compounds that Neuralstem believes may stimulate the brain’s capacity to generate neurons, potentially reversing pathologies associated with certain central nervous system (CNS) conditions. The company has completed Phase Ia and Ib trials evaluating NSI-189, its first neurogenic small molecule product candidate, for the treatment of major depressive disorder (MDD), and is expecting to initiate a Phase II study for MDD and a Phase Ib study for cognitive deficit in schizophrenia in 2015.
Neuralstem’s first stem cell product candidate, NSI-566, a spinal cord-derived neural stem cell line, is under development for treatment of amyotrophic lateral sclerosis (ALS). Neuralstem has completed two clinical studies, in a total of thirty patients, that met primary safety endpoints. In addition to ALS, NSI-566 is also in a Phase I trial in chronic spinal cord injury at UC San Diego School of Medicine, as well as in clinical development to treat ischemic stroke.
Neuralstem’s next generation stem cell product, NSI-532.IGF, consists of human cortex-derived neural stem cells that have been engineered to secrete human insulin-like growth factor 1 (IGF-1). In animal data presented at the Congress of Neurological Surgeons 2014 Annual Meeting, the cells rescued spatial learning and memory deficits in an animal model of Alzheimer’s disease.
