Objective: To determine if the bihormonal bionic pancreas (BHBP) improves glycemic control and reduces hypoglycemia in individuals with congenital hyperinsulinism (HI) and post-pancreatectomy diabetes (PPD) compared with usual care (UC).

Methods: Ten subjects with HI and PPD completed this open-label, crossover pilot study. Co-primary outcomes were mean glucose concentration and time with continuous glucose monitoring (CGM) glucose concentration <3.3 mmol/L.

Results: Mean (SD) CGM glucose concentration was 8.3 mmol/L (0.7) in the BHBP period vs. 9 mmol/L (1.8) in the UC period (p=0.13). Mean (SD) time with CGM glucose concentration <3.3 mmol/L was 0% (0.002) in the BHBP period vs. 1.3% (0.018) in the UC period (p=0.11).

Conclusion: Relative to UC, the BHBP resulted in comparable glycemic control in our population.
