Re: Forbes and DNDN On the "how does it improve OS and not PFS" question, this was also Dr Scher's (?) position at the AC (and in his letter). And I always considered it absurd. The data said Provenge most likely does slow progression (just not stat sig on the metric used). As a side point, with N = 500 we will likely hit SS in the PFS secondary. Is that why the Forbes artical has added the "counting deaths" talking point?
