Rida has a median progression-free survival of 17.7 weeks compared with GSK's 4.6 months. Sounds about the same to me........

Great observation. It raises a question for me also, is, or should the placebo arm be considered as the "what if we did nothing arm", or would the "what if we did nothing arm" comparator only observable in people not even in a study.

In either case, Rida gets you the same as GSK, placebo's notwithstanding. And as you point out kipster, there should be an explanation for the differences in placebo effects given that the drugs had the same effects.
