Randomized trial of continuous subcutaneous delivery of exenatide by ITCA 650 versus twice-daily exenatide injections in metformin-treated type 2 diabetes.

ABSTRACT:

Objective

To evaluate ITCA 650, a continuous subcutaneous miniature osmotic pump delivery system of exenatide versus twice-daily exenatide injections (Ex-BID) in subjects with type 2 diabetes.

Research design and methods

We conducted a randomized, two-stage, 24-week, open-label, phase 2 study in type 2 diabetes inadequately controlled with metformin. Stage I: 155 subjects were randomized to 20 or 40 μg/day of ITCA 650 or Ex-BID 5 → 10 μg. Stage II: 131 subjects were rerandomized to 20, 40, 60, or 80 μg/day of ITCA 650. Change from baseline for HbA1c, weight, and fasting plasma glucose were evaluated at weeks 12 and 24.

Results

HbA1c was significantly lower in all groups after 12 and 24 weeks. Stage I: mean change in HbA1c from a mean baseline of 7.9-8.0% was -0.98, -0
