1 Insulin pump treatment compared with multiple daily injections for treatment of type 2 diabetes (OpT2mise): a randomized open-label controlled trial Yves Reznik, Ohad Cohen, Ronnie Aronson, Ignacio Conget, Sarah Runzis, Javier Castaneda, Scott W Lee, for the OpT2mise Study Group www.thelancet.com, Published online July 3 2014 R3 박소영 / Prof. 오승준

2 INTRODUCTION Many patients with advanced type 2 diabetes require treatment with insulin. →Addition of basal insulin →Multiple daily injection However, such intensified regimens →Do not meet glycated haemoglobin targets in about 30% patients →Be associated with increased risks of hypoglycaemia and weight gain These limitations of multiple daily injection treatment show the need for new treatments for this group of patients.

3 AIM To further assess the potential benefits of pump treatment for type 2 diabetes For patients with type 2 diabetes who had not responded to a basal-bolus regimen after active insulin titration. To compare the efficacy and safety of pump treatment and multiple daily injection treatment A randomized, controlled trial (OpT2mise)

4 METHODS Randomized, parallel-group study 36 hospitals, tertiary care centers, referal centers –8 in Canada, 23 in Europe and Israel, 2 in South Africa, and 3 in the USA December 2010 ~ February 2014 Enrolled patients (age 30–75 years) with investigator-diagnosed type 2 diabetes. Exclusion: Pregnancy, ≥2 hypoglycaemia-related seizures or comas within the past 6 months, or significant diabetic complications 2-month run-in period, 6-month randomized phase, 6-month continuation phase

5 To stop all other antidiabetes drugs other than metformin To regulary monitor blood glucose with a minimum of three measurements per day (excluded if they checked their glucose fewer than 2.5 times per day) On completing the run-in phase, – glycated hemoglobin 8.0-12.0 % (64-108 mmol/mol) – daily insulin requirements of 0.7-1.8 units per kg (maximum 220 units per day) Randomly assigned (1:1) On completing the randomized phase, –Follow-up was continued for a further 6 months

6 Primary end points –The between-group difference in change in mean glyceted hemglobin from baseline to the end of the randomized phase Secondary end points –Changes from baseline to 6 months of continuous glucose monitoring data –Mean 24-h glucose concentrations –The area under the curve (AUC) for hypoglycemia and hyperglycemia –The time spent in hypoglycemia and hyperglycemia Safety endpoints –The number of severe hypoglycemic events –The number of ketoacidosis events

16 CONCLUSION Insulin pump treatment Significantly improved glycaemic control compared with multiple daily injection. Be considered a valuable therapeutic option for patients who are unable to reach glycated haemoglobin targets with multiple daily injection regimens.
