Johnson & Johnson hid studies showing its Risperdal anti-psychotic drug caused diabetes to protect billions of dollars in sales, a lawyer said in the first personal-injury claim over the medication to go to trial. Researchers at J&J’s Janssen unit knew as early as 1999 that a study found Risperdal caused diabetes at a higher rate than a competing drug and failed to hand over the results to regulators probing links between the disease and anti-psychotic medicines, Fletch Trammell, a lawyer for a former Risperdal user, told a New Jersey jury today in opening statements. “The evidence will show Janssen buried studies for a competitive advantage,” Trammell told jurors in state court in New Brunswick, New Jersey. J&J, the world’s second-largest health-products maker, is based in the city.
