Ultrarapid lispro (URLi), which has an accelerated pharmacokinetic profile and shows superior postprandial glucose control compared to lispro (Humalog(®)), is a potential candidate for use in these systems. Methods: In this double-blind, crossover trial over two 4-week treatment periods, we evaluated URLi in a hybrid closed-loop system using the Medtronic MiniMed� 670G system (670G). After a 2-week lead-in on lispro, 42 adults with type 1 diabetes were randomized to 1 of 2 treatment sequences of URLi and lispro delivered via the 670G. Primary endpoint was the percentage of time with glucose values within target range 3.9-10.0 mmol/L (70-180 mg/dL; %TIR). Results: Both treatments achieved %TIR over the 24-h period that was above the 70% minimum recommended by the International Consensus Guidance: URLi, 77.0%; lispro, 77.8%; P�=�0.339. %Time <3.0 mmol/L (54 mg/dL) was similar between treatments (URLi, 0.3%; lispro, 0.4%; P�=�0.548) and %time <3.9 mmol/L (70 mg/dL) was lower with URLi (1.5%) versus lispro (2.2%); P�=�0.009, while %time >10.0 mmol/L (180 mg/dL) was higher with URLi (21.5% [309.4 min] vs. 19.9% [287.2 min]; P�=�0.088). Mean sensor glucose was significantly higher with URLi versus lispro with least squares mean difference of 0.17 mmol/L or 3.0 mg/dL (P�=�0.011) between treatments. Insulin dose, %time in Auto Mode per week, and pump settings were similar between treatments. No serious adverse events (AEs) (including severe hypoglycemia) or discontinuations occurred, and the incidence of treatment-emergent AEs was similar between treatments. Although the overall incidence and rate of unplanned infusion set changes were similar between treatments, a significantly higher rate of unplanned infusion set changes due to infusion site reactions was seen during URLi treatment compared with lispro: 0.12 versus 0.00 events/30 days (P�=�0.063). Conclusions: URLi demonstrated good glycemic control that was comparable to lispro and showed a similar safety profile to lispro with the 670G hybrid closed-loop system.
