Echo Therapeutics, Inc., a medical device company developing its Symphony® CGM System as a non-invasive, wireless continuous glucose monitoring system, announced positive results from its multi-center clinical trial of the Symphony CGM System in surgical patients in hospital critical care units.
Symphony met the primary safety and effectiveness endpoints of the trial which involved the continuous monitoring of glucose levels in 32 subjects in the critical care units at four investigational sites. Using over 630 Symphony CGM glucose readings paired with reference blood glucose measurements in thirty-two (32) study subjects, CG-EGA showed that 97.9% of the readings were clinically accurate and 1.8% were benign errors, with a combined A+B value of 99.7%. The MARD (mean absolute relative difference) for the study was 12.5%. There were no adverse events reported from the skin preparation or the Symphony CGM sensor session. The range of glucose values was 49 - 324 mg/dL.
