In this completed, 20-week, open-label, parallel-arm trial at an academic hospital, 103 individuals aged 30–80 years with <7 years duration of T2DM were randomized (by computer-generated sequence) to 8-weeks treatment with (i) insulin glargine (Glar; n = 33), (ii) glargine + thrice-daily lispro (Glar/Lispro; n = 35), or (iii) glargine + twice-daily exenatide (Glar/Exenatide; n = 35), followed by 12-weeks washout. Here, INS is linked to type 2 diabetes mellitus.
