MONROVIA, Calif., 9/21/20 — AcuraStem (, a patient-based drug discovery platform company developing novel therapeutics for amyotrophic lateral sclerosis (ALS) and neurodegenerative diseases, announced today that Robert P. Bowser, Ph.D., Professor and Chair of Neurobiology at the Barrow Neurological Institute, and founder of Iron Horse Diagnostics, has been elected to AcuraStem’s scientific board of advisors. 

“We are excited to add our collaborator Dr. Robert Bowser to our advisory board. Bob is a worldwide leader in ALS biomarker development. His expertise will be critical as we look to validate key, CNS-specific, mechanistic biomarkers for our PIKFYVE programs,” said Sam Alworth, co-founder and chief executive officer of AcuraStem.

The disease-modifying potential of PIKFYVE inhibition for ALS was discovered by AcuraStem’s co-founder and close collaborator, Dr. Justin Ichida, in a landmark study appearing in Nature Medicine in 2017 (Shi Y et al Nature Med 2018). Reducing PIKFYVE levels in ALS patient motor neurons helps to prevent neurodegeneration, and could translate to improved motor function and survival for ALS patients. Supported by the National Institutes of Health and the Muscular Dystrophy Association, AcuraStem has been developing PIKFYVE-targeting therapies which are soon to enter IND-enabling studies.

Profiling these treatments across a large panel of ALS patient motor neurons on AcuraStem’s iNeuroRx® technology platform has shown that targeting PIKFYVE works broadly for both familial and sporadic forms of ALS, a large patient population lacking effective treatments in the development pipeline. The iNeuroRx technology platform is composed of disease-relevant neurons from many ALS patients and machine learning-driven assays. AcuraStem has discovered several novel and potentially disease-modifying therapeutic opportunities on the platform, and it is building out a robust pipeline of treatments. 

“Bob’s wealth of biomarker experience, co-chairing the Northeast ALS Consortium Biorepository and leading the Target ALS and ALS Association TDP-43-focused biomarker initiative, will be extremely valuable to expedite our programs into clinical trials and maximize their chances of success,” said Mr. Alworth.
