Primary: Change From Baseline in Glycosylated Hemoglobin (A1C) at Week 24, A1C is measured as a percent. Change from baseline in A1C at Week 24 was analyzed using constrained longitudinal data analysis (cLDA) method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, renal insufficiency stratum, baseline treatment with insulin stratum, time, the interaction of time by treatment, the interaction of time by renal insufficiency stratum, and the interaction of time by baseline treatment with insulin stratum., Baseline and Week 24|Percentage of Participants Who Experienced at Least One Adverse Event (Phase A: 24-week Placebo Controlled Period), An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue., Up to 28 weeks (including 28 days following the last dose of study therapy for participants who discontinued study drug)|Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (Phase A: 24-week Placebo Controlled Period), An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue., Up to 24 weeks|Percentage of Participants Who Experienced at Least One Adverse Event (Phase A: 24-week Placebo Controlled Period + Phase B: 30-week Active Controlled Period), An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue., Up to 58 weeks (including 28 days following the last dose of study therapy)|Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (Phase A: 24-week Placebo Controlled Period + Phase B: 30-week Active Controlled Period), An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue., Up to 54 weeks | Secondary: Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24, Change from baseline in FPG at Week 24 was analyzed using cLDA method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, renal insufficiency stratum, baseline treatment with insulin stratum, time, the interaction of time by treatment, the interaction of time by renal insufficiency stratum, and the interaction of time by baseline treatment with insulin stratum., Baseline and Week 24|Change From Baseline in A1C at Week 54, A1C is measured as a percent. Change from baseline in A1C at Week 54 was analyzed using cLDA method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, renal insufficiency stratum, baseline treatment with insulin stratum, time, the interaction of time by treatment, the interaction of time by renal insufficiency stratum, and the interaction of time by baseline treatment with insulin stratum., Baseline and Week 54|Change From Baseline in FPG at Week 54, Change from baseline in FPG at Week 54 was analyzed using cLDA method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, renal insufficiency stratum, baseline treatment with insulin stratum, time, the interaction of time by treatment, the interaction of time by renal insufficiency stratum, and the interaction of time by baseline treatment with insulin stratum., Baseline and Week 54|Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at Week 24, Based on an cLDA model including terms for treatment, renal status stratum, treatment on insulin at screening stratum, time, the interaction of time by treatment, the interaction of time by renal status stratum, and the interaction of time by treatment on insulin at screening stratum, with the constraint that the mean baseline is the same for all treatment groups. Excluding data after glycemic rescue or initiation of dialysis as well as participants classified with end stage renal disease (ESRD) on dialysis., Baseline and Week 24|Change From Baseline in eGFR at Week 54, Based on an cLDA model including terms for treatment, renal status stratum, treatment on insulin at screening stratum, time, the interaction of time by treatment, the interaction of time by renal status stratum, and the interaction of time by treatment on insulin at screening stratum, with the constraint that the mean baseline is the same for all treatment groups. Excluding data after glycemic rescue or initiation of dialysis as well as participants classified with ESRD on dialysis., Baseline and Week 54
