PRINCETON, N.J.--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE: BMY) today announced new 4-year results from the long-term extensions (LTE) of the BENEFIT and BENEFIT-EXT clinical trials of NULOJIX® (belatacept), the first selective T-cell costimulation blocker indicated for the prophylaxis of organ rejection in adult Epstein-Barr Virus (EBV) seropositive patients receiving a kidney transplant, in combination with basiliximab induction, mycophenolate mofetil (MMF), and corticosteroids. Results showed that the safety profile of NULOJIX through year 4 was consistent compared with results at year 3 with no new safety signals being identified, and that the renal function benefit versus cyclosporine was maintained through 4 years in patients enrolled in the LTE from both the BENEFIT and BENEFIT-EXT trials. The new data were presented in oral sessions at the 2012 American Transplant Congress (ATC) in Boston.
