Byetta LAR or as it is now called Bydureon didn't get FDA approval, but the issues raised were mainly to do with labeling. It looks like no issue with thyroid cancer was raised, unlike the black box labeling requirement with Liraglutide. The FDA have not requested any additional clinical trials.
Approval is now expected within 10 weeks. My Consultant reckons approval here will be quicker than normal because Bydureon is likely to be cheaper than Victoza. Byetta is already cheaper.
Who knows, but Bydureon will likely be a very good addition to the drugs available.
