FibroGen, Inc.
FibroGen, Inc. is a San Francisco biopharmaceutical company that spent three decades building first-in-class medicines around hypoxia-inducible factor (HIF) and connective tissue growth factor (CTGF) biology. Its best-known drug, roxadustat, is an oral treatment for anemia approved in China, Japan and Europe. After selling its China business to AstraZeneca in 2025 and paying down debt, the company rebranded as Kyntra Bio (Nasdaq: KYNB) in January 2026 to concentrate on oncology and rare disease, led by FG-3246, a first-in-class CD46-targeting antibody-drug conjugate for metastatic prostate cancer.
Pat Cotroneo
Pat Cotroneo is a seasoned life sciences financial executive who spent over two decades at FibroGen, Inc. (now Kyntra Bio), serving as Chief Financial Officer from 2008 to 2021. During his tenure, he guided FibroGen through two defining transformations: its landmark 2014 IPO - the largest biotech public offering in 12 years - and its evolution into a commercial-stage company with the launch of roxadustat in China in 2019. With 25+ years of senior financial leadership in life sciences, Cotroneo built his career at Deloitte & Touche, SyStemix (a Novartis subsidiary), and ultimately FibroGen, where he oversaw finance, accounting, human resources, and information technology before transitioning to Executive Advisor to the CEO.
