Bayer AG (BAYGn.DE) is set to face a fourth U.S. jury trial over allegations that its Roundup weed killer causes cancer, with four cancer patients in the hometown of its agricultural subsidiary Monsanto scheduled to begin making their case on Friday.
The lawsuit marks the first multi-plaintiff trial in the litigation over whether glyphosate, Roundups active ingredient, is carcinogenic, and is the first trial outside of California.
It is being held in St. Louis, where Monsanto was headquartered before Bayer bought the company in a $63 billion deal in 2018.
Three consecutive juries found the company liable for causing cancer with damages of tens of millions of dollars awarded to each plaintiff. Bayer is appealing those verdicts.
Court-appointed mediator Ken Feinberg has put the number of Roundup cancer claimants at more than 75,000 while Bayer said the claims it has been served with in court were below 50,000.
