Source ID: NCT03954834
Associated Drug: Tirzepatide
Title: A Study of Tirzepatide (LY3298176) in Participants With Type 2 Diabetes Not Controlled With Diet and Exercise Alone
Acronym: SURPASS-1
Status: COMPLETED
Study Results: YES
Results: https://ClinicalTrials.gov/show/NCT03954834/results
Conditions: Type 2 Diabetes Mellitus
Interventions: DRUG: Tirzepatide|DRUG: Placebo
Outcome Measures: Primary: Change From Baseline in Hemoglobin A1c (HbA1c), 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 Baseline + Pooled Country + Prior Use of oral antihyperglycemic medication (OAM) (Yes, No) + Treatment + Time + Treatment\*Time (Type III sum of squares)., Baseline, Week 40 | Secondary: Change From Baseline in Body Weight, Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (\<=8.5%, \>8.5%) + Prior Use of OAM (Yes, No) + Treatment + Time + Treatment\*Time (Type III sum of squares)., Baseline, Week 40|Percentage of Participants With HbA1c Target Value of <7%, Hemoglobin A1c (HbA1c) is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time., Week 40|Change From Baseline in Fasting Serum Glucose, Fasting serum glucose (FSG) is a test to determine sugar levels in serum sample after an overnight fast. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (\<=8.5%, \>8.5%) + Prior Use of OAM (Yes, No) + Treatment + Time + Treatment\*Time (Type III sum of squares)., Baseline, Week 40|Percentage of Participants With HbA1c Target Value of <5.7%, Hemoglobin A1c (HbA1c) is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time., Week 40|Mean Change From Baseline in Daily Average 7-Point Self-Monitored Blood Glucose (SMBG) Values, 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. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (\<=8.5%, \>8.5%) + Prior Use of OAM (Yes, No) + Treatment + Time + Treatment\*Time (Type III sum of squares)., Baseline, Week 40|Percentage of Participants Who Achieved Weight Loss ≥5%, Percentage of Participants who Achieved Weight Loss ≥5%., Week 40|Rate of Hypoglycemia With Blood Glucose <54 Milligram/Deciliter (mg/dL) [<3.0 Millimole/Liter (mmol/L)] or Severe Hypoglycemia, 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 HbA1c Group (\<=8.5%, \>8.5%) + Prior Use of OAM (Yes, No) + Treatment, with log (exposure in days/365.25) as an offset variable., Baseline through end of safety follow-up (up to week 44)|Pharmacokinetics (PK): Steady State Area Under the Concentration Time Curve (AUC) of Tirzepatide, Pharmacokinetics (PK): Steady State Area Under the Concentration Time Curve (AUC) of Tirzepatide. AUC is a combined measure obtained from Week 7, 15 and 23, and a single averaged measure of AUC was reported., Week 7, 15 and 23
