Glucotrack, Inc. announced that it is expanding its glucose monitoring technology to include measuring glucose in the epidural space. A continuous glucose monitoring system that takes readings in the spinal epidural space may be integrated with existing treatments for patients with Painful Diabetic Neuropathy (PDN). PDN is a progressive neurological disorder that affects approximately one-fifth of the more than 38 million Americans with diabetes, equating to more than 7 million individuals.

Its symptoms include pain and fatigue in the feet, legs, and hands which can significantly impact patients' quality of life and functional ability. Recently, Spinal Cord Stimulation (SCS) technology has been indicated as a treatment option providing significant long-term pain relief to these patients. A spinal cord stimulator is an implanted device, with electrodes placed in the epidural space, that sends low levels of electricity directly into the spinal cord to achieve pain.

Glucotrack's sensor has the potential to be integrated with existing SCS devices to measure epidural glucose in patients with PDN who are undergoing SCS treatment. Combining SCS and continuous glucose monitoring (CGM) could provide several possible advantages, such as simplifying device management for those patients. This is the second application of Glucotrack's technology for implantable continuous glucose monitoring, in addition to its development of a long-term Continuous Blood Glucose Monitoring (CBGM) system.

The preclinical testing compared the Glucotrack sensor against blood glucose and a commercially available subcutaneous CGM in an acute large animal model while varying blood glucose levels for several hours. The results demonstrated the Glucotrack epidural glucose values closely tracked both the blood glucose and subcutaneous CGM values. The study was completed with no adverse effect on the animals.

A second acute study successfully confirmed the repeatability of these results.
