Abstract | OBJECTIVE: MATERIALS/METHODS: We studied 80 T2D patients inadequately controlled [ glycosylated hemoglobin (HbA1c), 7.0%-9.5%] receiving stable metformin for ≥12weeks. They were a subset of participants to a phase 2 trial that received also a 240-min mixed-meal tolerance test (MTT) at baseline and study end. Patients received once weekly (QW) sc injection of taspoglutide 5, 10, or 20mg (n=21, 19, or 19), or placebo (n=21), plus metformin, for 8weeks. We measured postprandial plasma glucose (PPG) and insulin profiles, insulin secretion rate (ISR), oral glucose insulin sensitivity (OGIS) index; β-cell glucose sensitivity, glucagon/ glucose and insulin/ glucagon ratios, and insulin sensitivity-to- insulin resistance (or disposition) index. RESULTS: After 8 weeks of treatment, taspoglutide 5, 10, and 20mg QW doses vs. placebo improved mean PPG0-240 min (relative change from baseline: -22.1%, -25.9%, and -22.9% vs. -8.1%; P<0.005) and mean postprandial ISR0-240 min (+14%, +18%, and +23% vs. +1%; P<0.005 vs dose). Taspoglutide at 20mg QW dose also resulted in improvements from baseline in OGIS, β-cell glucose sensitivity, glucagon/ glucose and insulin/ glucagon ratios and the disposition index during the MTT. CONCLUSION:
