Concentric Analgesics

Concentric Analgesics, Inc. is a San Francisco based clinical-stage biopharmaceutical company developing non-opioid pain therapeutics. Its lead candidate, vocacapsaicin (CA-008), is a first-in-class prodrug that converts to capsaicin, a TRPV1 agonist that selectively desensitizes pain-conducting nerve fibers without sensory numbness or motor weakness, given as a single local injection during surgery. The program holds FDA Fast Track designation (2017) and Breakthrough Therapy designation (2018), and has been evaluated in Phase 2 trials in bunionectomy, total knee arthroplasty and open ventral hernia repair. The company is a drug developer, not a software vendor: it publishes no API, SDK, developer portal or other machine-readable surface, and as of this check its corporate website is an expired Squarespace account that returns HTTP 404 for every path.

Concentric Analgesics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Clinical Trials.

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/concentric-analgesics: open an issue to ask a question, or submit a pull request to add artifacts.
