Hi Hana,
Thanks for posting that link. Eli Lily and Amylyn were hoping to have this new weekly version available nearly a year ago but Amylyn, who are doing the clinical testing, were having difficulties in coming up with an appropriate delivery mechanism that would allow the exenatide to remain effective in a patient's body for a week. The article would indicate that this is now being independently tested, which looks like they have at last overcome the problem.
