PATIENTS ACHIEVING GOOD GLYCEMIC CONTROL (HBA1c <7%) EXPERIENCE A LOWER RATE OF HYPOGLYCEMIA WITH INSULIN DEGLUDEC THAN WITH INSULIN GLARGINE: A META-ANALYSIS OF PHASE 3A TRIALS

ABSTRACT Objective: Meta-analysis to compare hypoglycemia rates of basal insulin degludec (IDeg) with insulin glargine (IGlar) in patients with diabetes achieving good glycemic control (hemoglobin A1c [HbA1c] <7% at end of trial). Methods: In a preplanned meta-analysis, patient data from 7 randomized, treat-to-target, 26- or 52-week trials in patients with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) who administered IDeg (n = 2,899) or IGlar (n = 1,431) once daily were analyzed. Using a negative binomial regression model, this meta-analysis compared hypoglycemia rates in patients achieving HbA1c <7% at end of trial with IDeg (n = 1,347) and IGlar (n = 697). Results: In all trials, IDeg was noninferior to IGlar in HbA1c reduction from baseline. At end of trial, 2,044 patients (T2DM, n = 1,661; T1DM, n = 383) achieved HbA1c <7%. The overall confirmed hypoglycemia rate, defined as plasma glucose <56 mg/dL or severe hypoglycemia if requiring assistance, was significantly lower with IDeg...
