AcuraStem is a California-based biotechnology company employing cutting-edge technology in its efforts to find treatments and cures for neurodegenerative diseases (NDDs). AcuraStem’s team of PhDs, professors, tech entrepreneurs, and successful drug company veterans are today employing the latest scientific breakthroughs to address one of the most challenging, but we believe tractable, health problems of our time — amyotrophic lateral sclerosis (ALS).

Our best-in-class technology platform consists of complex cellular models from ALS patient cells and sophisticated assays which permit our scientists to model patient tissues in the laboratory. Using this advanced technology, we can evaluate the progression of disease and test existing FDA approved therapeutics, or a combination of therapeutic approaches, to find the most efficacious treatments to slow disease progression.

AcuraStem’s first therapeutic drug candidate, developed with the company’s novel Patient-Based Drug Discovery approach, is expected to enter clinical trials in 2021, after which the company will focus the new strategy on developing treatments for other neurodegenerative diseases.


AcuraStem's founders wanted a name that would communicate the team's vision for utilizing stem cell models in a new way. The name is intended to be a representation of a more accurate way to predict disease progression and a patient's response to therapy. Initially the team focused on the name "AcurateStem," but subsequently changed it to AcuraStem with a capital S emphasizing the use of stem cells. Another meaning embedded in the name is cure. We aim to accurately diagnose, and then potentially cure, the disease that we are working on with stem cells. With the name "AcuraStem," we convey the focus of the entire company in one simple, unique word that reflects the very nature of the endeavor that we are aiming to advance.
