简要总结
Patients with Type 2 diabetes and severe insulin resistance with very large insulin requirements who have failed all previous insulin regimens using non-concentrated forms of insulin (U100 insulin formulations) will receive 5X concentrated insulin (U500 regular insulin)infused via insulin pump.
详细描述
Patients with Type 2 diabetes who have severe insulin resistance and very large insulin requirements (over 1.4 units of insulin /kg/day) often fail insulin regimens with persistent poor blood glucose control when standard U-100 insulin formulations are used. This is due in part to poor absorption of the large insulin volumes required using these less concentrated standard insulin preparations. The hypothesis that using a concentrated form of insulin called U-500 Regular insulin and delivering it by infusion via insulin pump will lower the volume of insulin required and therefore improve insulin absorption, which will lead to improved blood glucose control, will be tested.

研究组 & 干预措施
All subjects active
All subjects will receive the experimental treatment (U-500 insulin via Omnipod) since they have already failed all other previous insulin treatment regimens.
干预措施: U-500 Insulin delivered by Omnipod (disposable insulin pump) (Drug)
结局指标
主要结局
Improvement in Glycemic Control as Assessed by Change in Hemoglobin A1c (HbA1c)
时间窗: 1 year
HbA1c is expressed as a percentage. This measurement represents an average of plasma glucose concentration for about 3 months. We will report the change in HbA1c measured at 12 months vs Baseline.
次要结局
- Percentage of Time Spent in Hypoglycemia(baseline versus 12 months)
- Patient Satisfaction With Insulin Delivery Method Via Insulin Delivery Rating System Questionnaire (IDRSQ)(Baseline versus 1 year)
