Final clinical studies for submission of a pre-market approval application to the FDA for a Bionic Pancreas that automates type 1 diabetes management

? DESCRIPTION (provided by applicant): We have built and extensively tested our bihormonal bionic pancreas (BP) in inpatient and real-world outpatient studies in subjects with type 1 diabetes (T1D). Through an eight-year collaboration between Boston University (BU) and the Massachusetts General Hospital (MGH), we have completed three 1- and 2-day inpatient studies testing a laptop version of the BP and three 5-day outpatient studies testing an iPhone version of the BP in adults with T1D (in downtown Boston), adolescents with T1D (in a diabetes camp), and pre-adolescents with T1D (in a diabetes camp). In collaboration among BU, MGH, the University of Massachusetts Medical Center, Stanford University, and the University of North Carolina, Chapel Hill, we completed an 11-day Bionic Pancreas Multi-Center outpatient study in adults with T1D testing the iPhone version of the BP at home and in the workplace without restrictions on activity or exercise. We have recently built a new bihormonal BP device platform in accordance with Class III medical device standards that integrates a microprecision dual-infusion pump that (1) separately delivers insulin and glucagon, (2) acts as a receiver for an FDA-cleared continuous glucose monitor (CGM), and (3) includes our clinically tested suite of mathematical control algorithms that autonomously determines and commands doses of insulin and glucagon based on CGM glucose data. This new device platform provides a turnkey solution that will standardize, simplify, and improve T1D therapy. Here we propose to conduct the Bionic Pancreas Pivotal Trial (BPPT), which will enroll 480 children and adults with T1D (ages 8 and older, HbA1c
