Centrexion Therapeutics

Centrexion Therapeutics is a late clinical-stage biopharmaceutical company headquartered at One Boston Place, Suite 3520, Boston, Massachusetts, developing novel non-opioid, non-addictive therapies for chronic pain alongside an emerging portfolio in immunology and inflammation. The company was founded by Sol Barer, Ph.D. — a founder of Celgene, who chairs the board — and by James N. Campbell, M.D., president and chief scientific officer and Professor Emeritus of neurosurgery at Johns Hopkins University School of Medicine. Jeffrey B. Kindler, formerly chief executive of Pfizer, joined as chief executive officer in 2013. Its lead asset, CNTX-4975, is a highly purified synthetic trans-capsaicin injected directly into the painful joint that produces analgesia by reversibly deactivating the end terminals of TRPV1-expressing primary afferent pain fibers, delivering pain relief that can last months while clearing the body within 24 hours; the FDA granted it Fast Track designation for moderate-to-severe osteoarthritis knee pain. Centrexion runs no developer program and publishes no product API, developer portal, API documentation, SDK or status page. The only machine-readable surface reachable without credentials is the WordPress REST content API behind centrexion.com, catalogued here, together with an llms.txt the site generates for AI crawlers.

Centrexion Therapeutics publishes 10 APIs on the APIs.io network, including Comments API, Custom Types API, Discovery API, and 7 more. Tagged areas include Company, Biopharmaceutical, Pharmaceuticals, Chronic Pain, and non-opioid-analgesics.

Centrexion Therapeutics’ developer surface includes authentication and 20 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.

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