Evaluation of the Effects of Heating the Vicinity of the Insulin Delivery Site by the InsuPatch Device During Daily Life

2014-08-27 03:14:05 | BioPortfolio

Summary

The aim of this study is to test the performance of the InsuPatch device in daily life. The primary target of the study is to evaluate safety aspect of daily device use. Additional aspects to be evaluated in the study are: the effect of the device on post prandial glucose level.

Description

Despite the recent years advance in rapid acting insulin analogues early postprandial hyperglycemia and late post prandial hypoglycemia are still common in insulin treated diabetic patients. It appears that even with these rapid acting insulins there is still a significant delay time and variability in the delay time between the changes in blood glucose levels following the meals and the absorption kinetics of insulin injected subcutaneously. Past studies using regular human insulin have demonstrated that using local stimulation at the injection site can dramatically improve regular insulin kinetics. The assumption was that local stimulation induces local increase in blood perfusion which improves insulin absorption from the injection site.

Following the above Insulin has developed the InsuPatch device. The intended use of the InsuPatch device is to improve insulin delivery into the blood when the insulin is infused using an insulin-infusion pump by controlled heating of the area surrounding the point of infusion.

The InsuPatch device consists of two components:

I) InsuPatch single-use, flat, heating pad with electrical wire which is attached by adhesive to the bottom of the Medtronic MiniMed Quick-set® infusion set. The user attaches the device to the infusion set prior to insertion of the infusion set catheter.

II) The InsuPatch case is used as a case for the Medtronic MiniMed Paradigm insulin infusion pump. The InsuPatch case contains an electronic unit and batteries.

The effect of the device on the pharmacokinetics (PK) and pharmacodynamics (PD) of the injected insulin were tested in Euglycemic clamp and meal tolerance test (MTT) studies. The effect of the device on insulin PK was evaluated by comparing insulin concentration in the meal MTT study with and without operation of the device. The effect of the device on insulin PD was evaluated using Euglycemic clamp protocol with and without operation of the device. The effect of the device on postprandial glucose excursions was tested by comparing the post meal glucose levels with and without operation of the device.

The main results of the study were:

1. An increase of 49% in the available insulin in the blood during the first 30 minutes post injection and 37% in during the first hour post injection (PK).

2. A reduction of 25% in the average glucose level during post-meal first two hours (PD).

3. A reduction of 43% in the time to peak action of insulin (PD).

The aim of this study is to test the performance of the InsuPatch device in daily life. The primary target of the study is to evaluate safety aspect of daily device use. Additional aspects to be evaluated in the study are: the effect of the device on post prandial glucose level.

Medical and Biotech [MESH] Definitions

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

The state of PREGNANCY in women with DIABETES MELLITUS. This does not include either symptomatic diabetes or GLUCOSE INTOLERANCE induced by pregnancy (DIABETES, GESTATIONAL) which resolves at the end of pregnancy.

Excessive thirst manifested by excessive fluid intake. It is characteristic of many diseases such as DIABETES MELLITUS; DIABETES INSIPIDUS; and NEPHROGENIC DIABETES INSIPIDUS. The condition may be psychogenic in origin.
