About Kyntra Bio Inc
Kyntra Bio, Inc. is a biopharmaceutical company headquartered in San Francisco, California. Once regarded as a promising developer of innovative therapies for anemia and fibrotic diseases, with a market capitalization of roughly $4 billion in 2018–19, the company's value collapsed following late-stage trial failures, regulatory setbacks, and a data manipulation scandal. By 2026, Kyntra was mainly reduced to a single early-stage oncology drug candidate. On January 8, 2026, FibroGen changed its name to Kyntra Bio and ticker symbol to KYNB.
