Reading about the upcoming FDA Advisory Committee meeting about the "son of Vioxx", Arcoxia, it appears that the same mistake is being made all over again.

Once again we have a COX-2 inhibitor being compared to an active comparator only. This time we have diclofenac instead of naproxen, another non-COX-2 and older NSAID. Again we have a conclusion of no difference between the two drugs--with no placebo arm against which we can compare the COX-2 inhibitor--and a conclusion of cardiovascular safety.

What is really needed is a study less like the VIGOR study and more like the APPROVe study, ie. one that also includes a placebo arm. That would allow one to infer conclusions that would be more meaningful to the public health.
