Another Gilead Exec Exits as CMO Cheng Steps Down

Xconomy San Francisco — 

Another top-level Gilead Sciences (NASDAQ: GILD) executive is stepping down. Andrew Cheng, a 19-year Gilead vet who was named chief medical officer of the Foster City, CA, company just four months ago, is leaving to “pursue another opportunity.” Former research chief Norbert Bischofberger left Gilead in March to run a biotech startup, Kronos Bio. And both CEO John Milligan and chairman (and ex-CEO) John Martin are heading for the exits soon as well. Milligan will step down at the end of the year, while Martin will leave the board when Gilead names a new leader.
