This is a study to assess the safety and efficacy of the addition of ipragliflozin once daily in Japanese participants with Type 2 diabetes mellitus (T2DM) who have inadequate glycemic control on sitagliptin, diet, and exercise therapy. The primary hypothesis for this study is that the addition of ipragliflozin compared with placebo provides greater reduction in hemoglobin A1C (HbA1c) as assessed by change from baseline at Week 24.

Change From Baseline in HbA1c at Week 24
HbA1c is measured as percent. Thus, this change from baseline reflects the Week 24 HbA1c percent minus the Week 0 HbA1c percent. Statistical analysis based on a constrained longitudinal data analysis (cLDA) model with terms for treatment, time, prior use of AHAs, the interactions of treatment by time, time by prior use of AHAs, treatment by time by prior use of AHAs, and baseline eGFR value with the constraint that the mean baseline HbA1c is the same for both treatment groups.
Time frame: Baseline and Week 24
Percentage of Participants Who Experienced at Least One Adverse Event (AE)
An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
Time frame: Up to 26 weeks
Percentage of Participants Who Discontinued Study Drug Due to an AE
An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
Time frame: Up to 24 weeks
Change From Baseline in FPG at Week 24
Change from baseline in FPG at Week 24 is defined as Week 24 FPG minus Week 0 FPG. Statistical analysis based on a cLDA model with terms for treatment, time, prior use of AHAs, the interactions of treatment by time, time by prior use of AHAs, treatment by time by prior use of AHAs, and baseline eGFR value with the constraint that the mean baseline FPG is the same for both treatment groups.
Time frame: Baseline and Week 24
Change From Baseline in 2-hr PMG at Week 24
Change from baseline in 2-hr PMG at Week 24 is defined as Week 24 2-hr PMG minus Week 0 2-hr PMG. Statistical analysis based on a cLDA model with terms for treatment, time, prior use of AHAs, the interactions of treatment by time, time by prior use of AHAs, treatment by time by prior use of AHAs, and baseline eGFR value with the constraint that the mean baseline 2-hr PMG is the same for both treatment groups.
Time frame: Baseline and Week 24
Change From Baseline in Glucose Total AUC0-2hr After Meal at Week 24
Change from baseline in glucose total AUC0-2hr after meal at Week 24 is defined as Week 24 glucose total AUC0-2hr after a meal minus Week 0 glucose total AUC0-2hr after a meal. Statistical analysis based on a cLDA model with terms for treatment, time, prior use of AHAs, the interactions of treatment by time, time by prior use of AHAs and treatment by time by prior use of AHAs, and baseline eGFR value with the constraint that the mean baseline glucose total AUC0-2hr after meal is the same for both treatment groups.
Time frame: Baseline and Week 24 (just before the loading meal [0 min], 30 min, 60 min and 120 min)
Change From Baseline in Body Weight at Week 24
Change from baseline in body weight at Week 24 is defined as Week 24 body weight minus Week 0 body weight. Statistical analysis based on a cLDA model with terms for treatment, time, prior use of AHAs, the interactions of treatment by time, time by prior use of AHAs and treatment by time by prior use of AHAs, and baseline eGFR value with the constraint that the mean baseline body weight is the same for both treatment groups.
Time frame: Baseline and Week 24
