Innovative Intravascular Glucose Monitor Passes First Human Trial, Promises Advanced Diabetes Management

Medical technology company Glucotrack has successfully completed its first human trial of an innovative intravascular continuous blood glucose monitoring (CBGM) system, marking a significant advancement in diabetes care technology. The study, conducted at InCor Hospital in São Paulo, Brazil, evaluated the safety and technical feasibility of a fully implantable device designed to provide real-time blood glucose measurements for insulin-dependent diabetes patients.

With approximately 38.4 million Americans living with diabetes, and 1.7 million adults managing type 1 diabetes, the potential impact of this technology is substantial. Current continuous glucose monitoring methods rely on measuring interstitial fluid, which can introduce delays in glucose level readings, particularly during rapid metabolic changes.

The first-in-human study enrolled six adult participants, including five with type 1 diabetes and one with type 2 diabetes, all undergoing intensive insulin therapy. Researchers implanted the CBGM sensor intravascularly and monitored participants for four days, with follow-up assessments to ensure no complications arose.

The study achieved its primary safety endpoint with no serious adverse events reported. Researchers noted only minor issues such as localized pain and minor bleeding, which were resolved without complications. Furthermore, the device demonstrated impressive technical performance, capturing 99% of data with a Mean Absolute Relative Difference of 6.7% when compared to traditional fingerstick glucose monitoring.

Building on these promising results, Glucotrack is preparing to launch a long-term clinical trial outside the United States. This multicenter study will enroll up to 30 participants and assess the full commercial version of the CBGM system, including the implantable sensor, subcutaneous electronics module, and companion mobile application.

The upcoming trial represents a critical step in developing a potentially transformative diabetes management solution. By measuring glucose levels directly from the bloodstream, the device could offer more accurate and timely information, helping patients better manage their condition and potentially reduce the risk of complications affecting major organs.

While the technology is still in development, this initial human trial signals a significant milestone in diabetes care technology. The potential for a discreet, long-lasting, and highly accurate glucose monitoring system could revolutionize how patients manage their metabolic health, offering hope for more precise and less invasive treatment strategies.
