A Study of Tirzepatide (LY3298176) Versus Insulin Degludec in Participants With Type 2 Diabetes

HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with covariates Baseline + Pooled Country + Baseline Oral Antihyperglycemic Medication (OAM) Use (Metformin (Met), Met plus SGLT-2i) + Treatment + Time + Treatment*Time (Type III sum of squares).

LS mean was determined by MMRM model with Baseline + Pooled Country + Baseline OAM Use (Met, Met plus SGLT-2i) + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment + Time + Treatment*Time (Type III sum of squares) as covariates.

LS mean was determined by MMRM model with variables Baseline + Pooled Country + Baseline OAM Use (Met, Met plus SGLT-2i) + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment + Time + Treatment*Time (Type III sum of squares).

Hemoglobin A1c (HbA1c) is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time. Imputed data includes observed value and imputed value if endpoint measure is missing. Missing endpoint measures are imputed by predictions from an MMRM analysis model using observed data in the efficacy analysis set and adjusted for Baseline Value, Pooled Country, Baseline OAM Use (Met, Met plus SGLT-2i), Treatment, Visit and Visit*Treatment.

The self-monitored plasma glucose (SMBG) data were collected at the following 7 time points: Morning Premeal - Fasting, Morning 2-hour Postmeal, Midday Premeal, Midday 2-hour Postmeal, Evening Premeal, Evening 2-hour Postmeal and Bedtime. LS mean was determined by mixed-model repeated measures (MMRM) model with variables Baseline + Baseline HbA1c Group (<=8.5%, >8.5%) + Pooled Country + Baseline OAM Use (Met, Met plus SGLT-2i) + Treatment + Time + Treatment*Time (Type III sum of squares).

Percentage of Participants who Achieved Weight Loss ≥5%

DTSQc, an 8-item questionnaire, assesses relative change in treatment satisfaction perceived frequency of hyperglycemia, and perceived frequency of hypoglycemia from baseline to week 52 or early termination.The treatment satisfaction score ranges from -18 to 18 where the higher the score the greater the improvement in satisfaction with treatment. The lower the score the greater the deterioration in satisfaction with treatment. The hyperglycemia and hypoglycemia scores range from -3 to 3 where negative scores indicate fewer problems with blood glucose levels and positive scores indicate more problems than before. LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline DTSQs + Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Baseline OAM Use (Met, Met plus SGLT-2i) + Treatment (Type III sum of squares).

The hypoglycemia events were defined by participant reported events with blood glucose <54mg/dL (<3.0 mmol/L) or severe hypoglycemia. Severe hypoglycemia is defined as an episode with severe cognitive impairment requiring the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These episodes may be associated with sufficient neuroglycopenia to induce seizure or coma. The rate of postbaseline hypoglycemia was estimated by negative binomial model: Number of episodes = Pooled Country + Baseline OAM Use (Met, Met plus SGLT-2i) + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment, with log (exposure in days/365.25) as an offset variable.
