Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a pilot, interventional clinical trial to assess the effectiveness and safety of artificial pancreas (AP) using the ARG algorithm closed-loop system in a monitored 3-day period outpatient study. Once the safety of the device has been validated in the open-loop first 3-day period (continuous subcutaneous insulin infusion (CSII) plus continuous glucose monitoring (CGM)) the investigators will move the study to the second 3-day closed-loop period, without carbohydrate (CHO) counting.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Non-hybrid closed-loop system

To compare two types of treatments:

During the first 3 days: Previous or conventional, with CSII plus CGM in open loop.

During the second 3 day period: AP with CSII plus CGM in a closed-loop system, through the ARG algorithm.
