Brief summary
This is a four-way crossover (non-parallel) study with each subject receiving three of the four arms. The study will enroll approximately 30 adult subjects with T2DM from age 20 to 75 inclusive. Following a 7-10 day Screening period, eligible subjects will enter a 3-day single-blind placebo run-in. On Day 4, each subject will be randomized to a treatment sequence that will include three treatment assignments for each of three treatment Periods according to the randomization scheme.
Detailed description
Following the screening, eligible subjects entered a 3-day, single-blind placebo run-in. On Day 4, each subject was randomized to a treatment sequence that included three treatment assignments for each of three treatment Periods according to the randomization scheme. Pre-assignment Details The number of participants receiving each Intervention, in each Period, is reported. Subjects received the randomized treatment from Day 4 through Day 8. There was a 24-hour single-blind placebo washout on Day 9. Each subject received placebo for one of the three treatment periods. Each subject also received 1 of the 3 active doses randomly in each of the two other treatment periods respectively. The dosing order is random.

Recruitment details
Following the screening, eligible subjects entered a 3-day, single-blind placebo run-in. On Day 4, each subject was randomized to a treatment sequence for each of three treatment periods, each period was either placebo or 1 of the 3 treatments). All subjects received placebo and only 2 of the 3 treatments.
Pre-assignment details
The number of participants receiving each intervention, in each Period, is reported. In each treatment period, each subject received randomly either placebo, qd, bid, or tid for each of 3 treatment periods. Subjects received the randomized treatment from Day 4 through Day 8. There was a 24-hour single-blind placebo washout on Day 9.
