November 21, 1996: Merck Official Concerned that Study Would Show that Vioxx Causes Heart Problems
A Merck official writes a memo on the question of whether the company should conduct a trial to demonstrate that Vioxx is gentler on the stomach than other painkillers. The memo notes that such a study would likely show that “there is a substantial chance that significantly higher rates” of cardiovascular problems will occur among the patients taking Vioxx.
