LY2189265, Sitagliptin + LY2189265
First Intervention Period: A single 1.5-milligram (mg) subcutaneous (SC) injection of LY2189265 on Day 1 (Treatment 1). Second Intervention Period: 100 mg of sitagliptin, administered orally, once daily on Day 1 to Day 18 with single SC injections of 1.5 mg LY2189265 immediately prior to the sitagliptin dose on Day 5 and Day 12 (Treatment 2). There was a washout of at least 21 days between treatments.
