Within the scope of the EU project "SPIDIMAN" a new glucose sensor technology is being developed which improves glucose measurement and allows a more exact insulin delivery which leads to a better blood glucose setting in patients with type 1 diabetes. Special target groups of the project are children and adolescents. JOANNEUM RESEARCH coordinates this four year project which comprises a consortium of nine multidisciplinary national and international partners.

The new glucose sensor technology is a so-called “single-port system” which allows glucose measurement and insulin delivery at the same site in the adipose tissue. Together with the insulin delivery needle special the optical glucose sensors are placed into the adipose tissue. The sensors are read-out by a miniaturized measuring device which is placed on the skin. Subsequently, glucose values are calculated.

Now, the new technology was tested in a first clinical study in humans. From a technical point of view, the tested single-port system is comparable with systems currently available on the market. In this first study important knowledge was obtained to further improve and advance the combination of glucose measurement and insulin delivery. This  single-port technology has a great potential to become the central element of an artificial pancreas system.

SPIDIMAN study in humans evaluates sensor performance

With the start of the clinical trial a major milestone within the SPIDIMAN project was achieved leading the project from the technical development phase to the clinical evaluation phase. With successfully completed biocompatibility tests, the clinical trial started end of July and is conducted at the Clinical Research Center of the Medical University of Graz. 12 type 1 diabetic patients volunteered to take part in the study. Each of them will wear two SPIDIMAN glucose readers to assess the sensor performance of the SPIDIMAN system. The 12h sensor tests are planned to start at 8 am in the morning and end at 8 pm in the evening, while glucose dynamics will be induced by high glycemic index breakfast and lunch followed by late and overdosed insulin boli. Reference blood glucose values were taken every 5 min throughout the study.

The statistical data analysis of this study is planned to be finished in October.
