AMLN -question re: intranasal

Dew,

I understand why clincal trials take so long when switching from daily (Byetta) to weekly (LAR). But if intranasal would also be given daily, and the safety/efficacy of Exenatide have already been established with Byetta, does there really need to be a "full" phase I trial? I would have thought that something as simple as a head-to-head test between Byetta injection and Exenatide intranasal to see if efficacy remained the same would almost be a "Phase II" trial.

Sorry if that's a dopey question.

Best regards,
Geoff
