The dietary supplement maker at the center of a federal trial of former Virginia Gov. Bob McDonnell and his wife says it's halting sales of its product called Anatabloc.
Rock Creek Pharmaceuticals Inc. said Monday it is voluntarily stopping sales while it sorts out issues with the Food and Drug Administration.
Last year, the federal agency sent a warning letter to the company known as Star Scientific saying that its products contain a new dietary ingredient that requires approval before it can be marketed.
The agency also said the company's website had improperly promoted Anatabloc as a drug by suggesting it can be used to treat various diseases.
The McDonnells are charged with accepting gifts and loans from Star Scientific's former CEO in exchange for promoting his products.
