Medical doctor Patrick Soon-Shiong invented the cancer drug Abraxane. It became a blockbuster thanks to its efficacy against pancreatic cancer. He sold his drug companies Abraxis in 2010 and American Pharmaceutical Partners in 2008 for a combined $9.1 billion. He took his cancer drug maker NantKwest public in 2015 and his biotech startup NantHealth public in 2016. He owns NantWorks, a network of health startups, and has stakes in media firm Tribune Publishing and the Los Angeles Lakers. He bought the Los Angeles Times and San Diego Tribune for $500 million in June 2018. In May 2020, Soon-Shiong's ImmunityBio was selected for the federal government's "Operation Warp Speed" to help quickly develop a Covid-19 vaccine.
