Brief summary

The primary objective was to demonstrate the superiority of insulin glargine over sitagliptin in reducing Glycosylated Hemoglobin A1c (HbA1c) from baseline to the end of the treatment period. Secondary objective was to assess the effect of insulin glargine in comparison with sitagliptin on: * HbA1c level * Fasting Plasma Glucose (FPG) * 7-point plasma glucose (PG) profiles * Percentage of patients with HbA1c \<7% and \<6.5% Safety objectives consisted of: * Hypoglycemia occurrence * Body weight * Overall safety

Participant flow

Recruitment details

EASIE was a multicenter, international, randomized, open-label trial conducted from November 12, 2008 to July 28, 2011.

Pre-assignment details

A total of 732 patients were screened in 96 centers in 17 countries. The study included an initial 2-week screening period. A total of 217 patients were screen failures. The main reason for screen failure was Glycosylated Hemoglobin A1c (HbA1c) inclusion criterion not met (146 patients).

Outcome results

Primary

HbA1c: Change From Baseline to Study Endpoint

Change in HbA1c from baseline to study endpoint defined as the last available HbA1c value measured during the 24-week treatment period.

Time frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14

Population: The population analyzed for this outcome measure consisted of the subset of mITT patients who had both baseline and endpoint measurements.~The Last Observation Carried Forward method was used for imputing missing data for the end of treatment value.

7-point Plasma Glucose Profile: Change From Baseline to Study Endpoint

7-point plasma glucose recorded before and after breakfast, before and after lunch, before and after dinner and at bedtime. Change = study endpoint - baseline.

Time frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14

Population: The population analyzed for this outcome measure consisted of the subset of mITT patients who had valid 7-point plasma glucose profiles (4 points needed for a valid profile) both at baseline and endpoint.~Depending on the time point, few values were missing.~Adjusted means were estimated from ANCOVA model using baseline value as covariate.
