And secondly John, if you could just review the characteristics that you look forward for a go/no-go decision on 702? Thanks, like I said, date is coming Q3."

    John Alam

    "Well, I actually can't provide you any specifics on the back up on the follow on program. It's just for let's say it�s a highly competitive field and we have a research program that's ongoing.

    << backup compounds to TVR >> is not a correct word to say. He, of course, meant to say he wants to know about the second generation compounds. John understood what Meg meant, and answered that Vertex has a program to generate such compounds which would be competitive against other 2nd generation compounds.
