David Hung, M.D.

Founder, President and Chief Executive Officer

Dr. Hung founded Nuvation Bio in 2018 and serves as President and Chief Executive Officer and member of the Board of Directors.

Dr. Hung founded Medivation, Inc., in 2003, raising a total of $433 million in public offerings over the life of the company to reach a market cap of more than $14 billion, providing investors with a return on investment of 21,000%.

For his role in creating Medivation, Dr. Hung was named the Life Sciences category winner and Overall U.S. winner across all categories of the 2014 Ernst & Young Entrepreneur of the Year Award.

Dr. Hung identified, in-licensed and led bench-to-bedside development of enzalutamide (XTANDI®) for advanced prostate cancer. At Medivation, XTANDI was taken from first in vitro laboratory experiment to FDA approval in seven years, one of the fastest development timelines in pharmaceutical history. XTANDI, approved in 60+ countries, reached blockbuster drug status, exceeding $3.7 billion in global annual sales in 2019.

At Medivation, Dr. Hung identified, in-licensed and developed talazoparib, a potentially best-in-class PARP inhibitor, which was approved by the FDA in October 2018, and the immune-oncology agent, pidilizumab, which demonstrated robust effects in Phase 2 studies and is now a promising Phase 3-ready asset.

Between Medivation and founding Nuvation Bio, Dr. Hung served for 10 months as Chief Executive Officer at Axovant Sciences before tendering his resignation. Prior to founding Medivation, he served as President and Chief Executive Officer of ProDuct Health, Inc., a venture-backed startup medical device company founded in 1998 that developed, manufactured and commercialized a breast microcatheter – that he invented – for breast cancer risk assessment.
