Delaware Court Sides With Zantac Makers on Cancer Claims

The Delaware Supreme Court rejected the legitimacy of expert testimony linking the heartburn drug Zantac to cancer, in a major win for makers of the product.

In a unanimous ruling Thursday, the state’s highest court agreed with the argument of companies including GSK Plc, Pfizer Inc. and Boehringer Ingelheim Pharmaceuticals that Superior Court Judge Vivian Medinilla erred in allowing the cancer testimony and letting the cases proceed to trial.
