The GlucoPred Investigation II (GPI-II)

An Open, Controlled Investigation of Measurement Precision, System Accuracy and User Performance Evaluation in Subjects With Diabetes Mellitus Type 1 Using GlucoPred, a Non-invasive Continuous Blood Glucose Measurement Device

Diabetes mellitus type 1 (DM1) is an autoimmune metabolic disease in which the insulin producing cells in the pancreas are destroyed and the subject is left totally dependent of external supply of insulin. There is no known cure for DM1 except for in very specific situations. Thus, management of DM1 concentrates on keeping blood glucose levels as close to normal levels. As an aid to subjects with DM1 for managing their blood glucose levels as close to normal as possible, blood glucose monitoring systems have been developed. Available blood glucose monitoring systems today require a capillary blood sample that is analysed by a glucose meter. Subjects are normally advised by health care professionals on the appropriate blood glucose monitoring regime for their condition. However, many subjects fail to measure blood glucose as often as needed to achieve good blood glucose control despite every effort from health care professionals. Research and development of non-invasive interstitial blood glucose monitoring methods is ongoing. All attempts to develop a non-invasive continuous glucose measuring device have so far failed. Prediktor Medical AS has developed a non-invasive sensor, GlucoPred, based on the combination of several non-invasive measurement principles and multivariate analysis and dynamic models of glucose/insulin interaction. The device will be body mounted in the form of a bracelet or a watch communicating with a mobile phone or a tablet for data presentation and collection. Development of GlucoPred is now at a stage where testing of the sensor in subjects under controlled settings is required before further development can take place. If successful, this will be a major step ahead for all patients with diabetes and markedly increase their possibility to take care of their disease on a day to day basis without the burden of frequent blood sampling or wearing an invasive device.
