On a conference call this evening, Amylin executives said conducting a new study to prove Bydureon does not cause prolonged heart rhythms could take until the end of next year.
These might have predicted, for instance, which Vioxx patients were at low risk for heart attacks but could nottake other painkillers due to stomach problems.
Nissen also points out that the patients in the study are sicker than the average heart patient and that the results may not translate to most patients who take Zetia or Vytorin.
Ms Stacey said the new modular English GCSEs at the heart of the fiasco were too flexible and "not sufficiently resilient" totake the pressure they were put under.
