Cygnus preclinical data

CYGN (Redwood City, Calif.) published results comparing its transdermal extraction electrode system prototype with measures of serum glucose by finger sticks. Using three different measures, the flux of glucose extracted across the skin correlated with the finger stick measure.

As reported in Nature Medicine, results from five diabetics showed that only 4 of 140 data points deviated from a clinically acceptable variation in correlation between the two methods of glucose measurement. Average correlation coefficient was 0.89. Mean absolute error was 12.9 percent, a value comparable to currently available self-testing glucose monitors. ...
