Dennis Prestholdt credits the past three years of his life to Johnson & Johnson (JNJ)’s Zytiga, the first prostate cancer pill to win U.S. marketing approval in a family of treatments that offer new ways to stymie the male hormones that fuel tumor growth.Prestholdt, 67, a retired engineer at Honeywell International Inc., began taking Zytiga in 2008 as part of a clinical trial. On April 28, the drug was cleared for sale and, within five years, may generate $2.1 billion a year, said Jami Rubin, a Goldman Sachs Group Inc. analyst in New York.
