A Rhode Island doctor has been indicted on 19 federal counts that accuse him of receiving kickbacks on prescriptions of a highly addictive painkiller that were written for patients who didn't need the drug.
Jerrold Rosenberg, a clinical assistant professor at Brown University, pleaded not guilty Thursday.
He's the latest person to be caught up in a federal investigation surrounding the Arizona-based drug manufacturer, Insys Therapeutics. The company is accused of rewarding doctors for prescribing large amounts of its fentanyl spray.
