Primary Objective:

  • To assess the efficacy of insulin glargine as measured by changes of HbA1c levels from baseline in type 2 diabetes mellitus (T2DM) patients following GLP-1 failure.

Secondary Objective:

  • To determine the change in glycemic control, safety, and treatment satisfaction in insulin glargine use in patients following GLP-1 failure.
