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.
