Nocturnal Insulin-Glucose in Hospital: Tight Control

Not Applicable

Completed

• Conditions: Type 1 Diabetes
• Interventions: Device: Artificial pancreas system consisting of a predictive rule-based algorithm integrated on the Medtronic Portable Glucose Control System (PGCS)

• Registration Number: NCT02160184
• Lead Sponsor: Corporacion Parc Tauli

Brief Summary

The aim of the study is to assess the efficacy and safety of a closed-loop system consisting of a predictive rule-based algorithm integrated on the Medtronic Portable Glucose Control System (PGCS) in patients with type 1 diabetes for controlling the nocturnal and post-breakfast periods. Intervention will be to apply the automated closed-loop system by administering a subcutaneous insulin microbolus every 5 minutes depending on reading from a continuous glucose measurement (CGM) system.
