Automated 'Artificial Pancreas' Controls Blood Glucose Levels in Diabetes Patients for First Time

Date:6/8/2009

thm that is robust and straightforward to implement. It's become the gold standard." The UCSB APS software platform is also being used by a number of other teams working on the artificial pancreas project, but no other team has advanced yet to wholly-automated clinical trials.

Closed loop trials were performed in four patients for a mean duration of 5 hours (range of 2-7 hours) and included a meal of 30 grams of carbohydrates. The mean Low Blood Glucose Index was 0.02 (range 0-0.06), the mean High Blood Glucose Index was 9 (range 4.2-15), and the median Daily Risk Range was 'low' (range 'low' to 'moderate').

The poster was presented in New Orleans by Matthew Percival of Doyle's research group. Other researchers in the study included Dr. Eyal Dassau, senior investigator, and Dr. Benyamin Grossman, both of Doyle's group; and Sansum's Dr. Lois Jovanovic, CEO and Chief Scientific Officer, and Dr. Howard Zisser, Director of Clinical Research.

The research is part of the artificial pancreas project, which is funded by the Juvenile Diabetes Research Foundation and is being conducted by an international group of diabetes research centers. The project's first goal is to integrate an insulin pump and continuous blood glucose monitor to closely replicate a healthy pancreas for patients with type 1 diabetes--patients whose pancreases no longer produce insulin, which is used by the body to control blood glucose levels. An artificial pancreas will allow for tighter and automated control of blood glucose levels, which would significantly help to avoid the long-term complications of the disease.

UC Santa Barbara is a leading research institution. The two groups at UCSB involved in this study are the Department of Chemical Engineering, in 2007 ranked ninth in the United States and second in the University of California by U.S.
