Study Description
Brief Summary:
The objective of the study is for clinical staff to gain experience using the proposed artificial pancreas system named inControl and the inControl Cloud and assess 24/7 in-home usability prior to initiating a large randomized controlled trial.

Condition or disease Intervention/treatment
Diabetes Mellitus, Type 1 Device: Artificial Pancreas

Detailed Description:

Participation in this study will require 5 study visits over 2-4 weeks.

  • Visit 1: screening/enrollment visit to assess study eligibility.
  • Visit 2: continuous glucose monitor (CGM) training and initiation session based upon current or prior use of a CGM; if subject doesn't currently use a CGM, subject will be trained and may be asked to wear the CGM at home for 1 week.
  • Visit 3: subjects will be taught how to use the study insulin pump.
  • Visit 4: subjects will be trained on the use of inControl and wear it at home for 14 days.
  • Visit 5: subjects will return study equipment and to complete questionnaire.

Arms and Interventions

Arm Intervention/treatment
Experimental: Artificial Pancreas
The primary outcome is a qualitative assessment of the system's suitability for use in a large-scale in-home clinical trial based on the results of the Technology Acceptance questionnaire and feedback from clinical staff.
Device: Artificial Pancreas
Subjects will be provided the Artificial Pancreas (AP) system which includes the inControl Diabetes Management Platform, a study insulin pump and continuous glucose monitor. This AP system is designed to help control blood sugar in people living with type 1 diabetes.
Other Name: inControl Diabetes Medical Platform

Outcome Measures

Primary Outcome Measures :
  1. The primary outcome is a qualitative assessment of the system's suitability for use in a large-scale in-home clinical trial based on the results of the Technology Acceptance questionnaire and feedback from clinical staff. [ Time Frame: 2 weeks ]
