Study: NCT03577158

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Closed-loop controller with exercise mitigation module
Description: Each subject will undergo three exercise tests, each one at 1-2 week intervals, thus completing the 3 experiments in about 6 weeks. The day of the experiment, the participant will do 3 sets of 15 minutes of cycloergometer at 70% of VO2max with 5 minutes of rest between them. On the first arm, participants will receive Sliding Mode Reference Conditioning (SMRC) Closed-loop insulin administration with a mitigation mode, based on subcutaneous continuous glucose monitoring (First arm, Closed-loop study with mitigation module).~Commercial insulin infusion systems and continuous glucose monitoring devices will be used.
