A Johnson & Johnson subsidiary and a California investment firm have agreed to an $11.5 million settlement resolving whistleblower claims over a cancer treatment system that was allegedly marketed off label to children.

The U.S. Attorney’s Office for the Eastern District of Pennsylvania, which announced the settlement, said J&J subsidiary Medical Device Business Services Inc. will provide $10 million toward the settlement, while The Gores Group, an investment firm based in Los Angeles, will pay $1.5 million.
