Fault Detection, Zone MPC and DiAs System in T1D

This is a randomized crossover study testing the efficacy of the Fault Detection algorithms using the Zone MPC algorithm and DiAs artificial pancreas platform in adult patients with type 1 diabetes. The trial will last for 6 weeks for each individual subject, with three weeks using the AP algorithm and three weeks using sensor augmented pump in a randomized order

Stanford is currently not accepting patients for this trial.

   completion of any aspect of the protocol

   7. Subject is currently participating in another investigational device or drug study
   within 30 days or 5-half-lives of the drug.

   8. Subject has a history of any cardiac or vascular disorder including, but not limited
   to, myocardial infarction, unstable angina, coronary artery bypass surgery, coronary
   artery stenting, transient ischemic attack, cerebrovascular accident, angina,
   congestive heart failure, arrhythmia or thromboembolic disease

   9. Subject has a history of hepatic disease

10. Subject has renal failure on dialysis

11. Systolic blood pressure > 160 mmHg on screening visit

12. Diastolic blood pressure > 90 mmHg on screening visit

13. Subjects with inadequately treated thyroid disease or celiac disease

14. Subject has a neurologic disorder that in the judgment of the investigator will affect
   completion of the protocol

15. Subject has received inpatient psychiatric treatment in the past 6 months

16. Subject consumes more than an average of 4 standard alcoholic drinks/day in the last
   30 days

17. Subject has an active skin condition that would affect sensor placement

18. Subject is unable to avoid acetaminophen for the duration of the study

19. Current use of oral/inhaled glucocorticoids or other medications, which in the
   judgment of the investigator would be a contraindication to participation in the study

20. Subject is currently on beta blocker medication -
