Glucotrack Announces Publication of Peer-Reviewed Study Supporting Long-Life Sensor Design for Implantable Continuous Blood Glucose Monitoring Technology

RUTHERFORD, N.J., April 21, 2026 (GLOBE NEWSWIRE) -- Glucotrack, Inc. (NASDAQ:GCTK) ("Glucotrack" or the "Company"), a medical technology company focused on the design, development, and commercialization of novel technologies for people with diabetes, today announced the publication of a peer-reviewed scientific article in the Institute of Electrical and Electronics Engineers (IEEE) Sensors Journal characterizing the long-term in-vitro stability of electrochemical glucose sensors of the type used in the Company's fully implantable continuous blood glucose monitoring (CBGM) system. The findings represent the first year-long measurement of glucose oxidase enzyme decay reported in the literature and support the feasibility of long-life implantable continuous glucose monitors.

The publication, titled "Year-Long Measurement of Glucose Oxidase Deactivation in Electrochemical Glucose Sensors," (Ernst, S. et al.), examined the long-term in-vitro performance and stability of an electrochemical glucose sensor based on glucose oxidase, the enzyme class used in Glucotrack's CBGM, over a one-year period.

The objective of the study was to assess sensor performance during the final year of its intended functional life. Accordingly, sensors used in the study were constructed to reflect approximately two year old devices. The findings represent the first year-long measurement of glucose oxidase enzyme decay, providing higher-confidence in the design of our long-life implantable glucose sensor.

Glucotrack partnered with TTP, a United Kingdom‑based scientific and engineering organization with experience supporting life sciences and medical device innovation, for this study and publication. The article was published on April 7, 2026 in the highly regarded technical journal, the IEEE Sensors Journal, part of the Institute of Electrical and Electronics Engineers, a global organization of over 486,000 leading STEM professionals worldwide, and is available online here.

"This work provides externally reviewed scientific evidence relevant to the design of long-life implantable glucose sensors. Peer-reviewed characterization of foundational sensor data is an important step as we continue to advance our development program and work toward clinical and regulatory milestones," commented Dr. Paul Goode, President and Chief Executive Officer of Glucotrack.

"TTP has a strong reputation in our space, and we had a very positive experience working with their team. We anticipate that this article, among other similar projects we have in process, should serve our team well as we work towards the submission of our IDE with the FDA in the near term," concluded Dr. Goode.

This publication is one part of Glucotrack's ongoing effort to build a transparent, peer-reviewed technical foundation for the development of its CBGM technology. Glucotrack previously reported first-in-human clinical results demonstrating a highly-accurate MARD of 7.7% and a 99% data capture rate, with no procedure- or device-related serious adverse events.
