This is a study assessing the feasibility of deploying the iLet bionic pancreas system in the insulin-only configuration to pump-naïve MDI users with type 1 diabetes, in the setting of being recruited from community-based primary care practices and being trained and managed by primary care providers (PC group), and in pump- and CGM-experienced (sensor-augmented pump or hybrid closed-loop) users with type 1 diabetes recruited from, trained, and managed by an academic endocrinology practice (EN group). In both practice settings, the exclusive use of telehealth (TH) visits will be assessed, as will the use of in-person (IP) visits. We will enroll 40 adult volunteers (≥ 18 years old) with type 1 diabetes, 20 who are insulin pump naïve MDI users enrolled from community primary care practices by University of Colorado Family Medicine (PC group) and 20 who are technology-savvy sensor-augmented pump or hybrid closed-loop users enrolled by the Massachusetts General Hospital Diabetes Clinical Research Center (EN group). Ten of the participants at each center will be trained and managed throughout the trial using in-person visits (PC-IP and EN-IP groups) and the other ten from each center will be trained and managed throughout the trial exclusively via telehealth visits (PC-TH and EN-TH groups). This will result in four study cohorts overall (endocrinology in-person, endocrinology telehealth, primary care in-person, primary care telehealth). Subjects in all four groups will each participate, in random order, in one 14-day study arm under their own usual care (UC arm) and one 14-day study arm under the insulin-only configuration of the iLet bionic pancreas (iLet arm).
This is a study assessing the feasibility of using the insulin-only configuration of the iLet bionic pancreas with initiation in pump-naïve people with type 1 diabetes in a primary care practice with either in-person training and follow-up (PC-IP) or with training and follow-up via telehealth (PC-TH). As a comparison, the iLet will be initiated by an academic endocrinology practice with either in-person training and follow-up (EN-IP) or with training and follow-up via telehealth (EN-TH).
