DR. I had one of those conversations and my gut feeling was the control group which had a surprising high PFS number may be having a similar OS. While I expect the OS data w/Bavi to be excellent, the control group may also be above historical norms and negate the Bavi results. This would cause the results to be a shoulder shrug rather than a "needle Mover" with our PPS. Again this a personal concern and was not communicated as the actual case by IR. Do you have any reason to believe I am off base?.
