Safety and efficacy of twice-daily exenatide in Taiwanese patients with inadequately controlled type 2 diabetes mellitus.

Background/purpose: Exenatide has been predominantly studied in non-Asian populations. The purpose of this study was to investigate the safety and efficacy of twice-daily (BID) exenatide versus placebo in a subpopulation of Taiwanese patients from a larger study on Asian patients.

Methods: Patients unable to achieve glycemic control with metformin alone or metformin in combination with sulfonylurea were randomly assigned to self-administer either 5 μg exenatide or placebo BID for 4 weeks, then 10 μg exenatide or placebo BID for an additional 12 weeks, in addition to their regular oral therapy.
