AcuraStem

AcuraStem, Inc. is a privately held, patient-based biotechnology company headquartered in Monrovia, California, developing therapeutics for neurodegenerative diseases including sporadic ALS (amyotrophic lateral sclerosis) and frontotemporal dementia (FTD). The company's proprietary iNeuroRx drug-discovery platform builds disease models from induced pluripotent stem cells (iPSC) taken from individual patients, in place of animal models, and pairs them with machine-learning analysis to identify and validate targets. Its lead antisense oligonucleotide candidate, AS-241 (PIKFYVE), is advancing toward first-in-human testing with California Institute for Regenerative Medicine (CIRM) grant support. AcuraStem is a therapeutics developer rather than a software vendor: it publishes no public API, developer portal, SDK, or machine-readable contract of any kind. This profile records that absence with the probe evidence behind it.

AcuraStem is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Therapeutics, Life Sciences, and Drug Discovery.

AcuraStem’s developer surface includes engineering blog and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/acurastem: open an issue to ask a question, or submit a pull request to add artifacts.
