John Kapoor, founder of Insys Therapeutics convicted

BOSTON — A federal jury found the top executives of Insys Therapeutics, a company that sold a fentanyl-based painkiller, guilty of criminal racketeering charges involving bribing doctors to prescribe dangerous opioids to patients who didn’t need them, New York Times reported.

The jury, after deliberating for 15 days, convicted the company’s founder, the onetime billionaire John Kapoor, 75, of all charges in the case.

During the 10-week trial, federal prosecutors had detailed how Insys’s audacious marketing plan — which included paying doctors for sham educational talks and luring others with lap dances — sought to spur sales of its painkiller, Subsys, an under-the-tongue spray that was approved to treat patients with cancer.

In addition to Mr. Kapoor, the other executives found guilty in the case were Richard M. Simon, the former national director of sales; Sunrise Lee and Joseph A. Rowan, both former regional sales directors; and Michael J. Gurry, former vice president of managed markets.

The former chief executive, Michael L. Babich, pleaded guilty to conspiracy and mail fraud charges.
