- Change from Baseline in Hemoglobin A1c (HbA1c) [ Time Frame: Baseline, Week 26 ]
- Time in Glucose Range [ Time Frame: Week 22 to Week 26 ]Time in glucose range between 70 and 180 milligram/deciliter (mg/dL) [3.9 and 10.0 millimole/liter (mmol/L)] inclusive, measured by continued glucose monitoring (CGM) 4 weeks prior to week 26
- Nocturnal Hypoglycemia Event Rate [ Time Frame: Baseline to Week 52 ]The event rate of participant-reported clinically significant nocturnal hypoglycemia (<54 mg/dL or severe) measured during treatment phase up to week 52.
- Change from Baseline in Fasting Glucose [ Time Frame: Baseline, Week 26 ]Change from baseline in fasting glucose measured by self-monitoring of blood glucose (SMBG).
- Glucose Variability [ Time Frame: Week 22 to Week 26 ]Glucose variability measured by CGM 4 weeks prior to week 26
- Basal Insulin Dose [ Time Frame: Week 26 ]
- Bolus Insulin Dose [ Time Frame: Week 26 ]

- Rate of Composite Level 2 and 3 Hypoglycemia Events [ Time Frame: Baseline to Week 52 ]
- Change from Baseline in Body Weight [ Time Frame: Baseline, Week 26 ]
- Time in Hypoglycemia Range [ Time Frame: Week 22 to Week 26 ]Time in hypoglycemia range defined as time in hypoglycemia with glucose <54 mg/dL, measured by CGM 4 weeks prior to week 26.
- Time in Hyperglycemia Range [ Time Frame: Week 22 to Week 26 ]Time in hyperglycemia range defined as glucose >180 mg/dL, measured by CGM 4 weeks prior to week 26.
- Change from Baseline in Diabetes Treatment Satisfaction Questionnaire-Status Version (DTSQ) [ Time Frame: Baseline, Week 26 ]DTSQ consists of 8 items and assesses the overall treatment satisfaction and perceived frequency of hyperglycemia and hypoglycemia.
