Abstract
We conducted a non-inferiority randomized crossover trial to alleviate carbohydrate counting (CC) in people with diabetes using automated dual-pump delivery of faster aspart (Fiasp) and pramlintide. Adults (N=15, 9 F, 39 ± 14 years, A1c 7.2 ± 0.9%) and adolescents (N=15, 8 F, 16 ± 1 years, A1c 8.4 ± 0.9%) used (i) Fiasp and placebo with CC, (ii) Fiasp and pramlintide with meal announcement (MA) , and (iii) Fiasp and placebo with MA for 2 weeks. Fiasp and pramlintide were delivered at a fixed 1 U:µg ratio to mimic a co-formulation. MA arms delivered fixed, user-specific priming meal boluses, independent of carbohydrate content. Prior to the first arm, participants had a 1-week run-in with automated Fiasp (single pump) delivery and CC, with mean time in range (70-180 mg/dL) of 71% in adults and 64% in adolescents. In adults, mean time in range was 65% on Fiasp and placebo with CC, 71% on Fiasp and pramlintide with MA, and 64% on Fiasp and placebo with MA; non-inferiority with a pre-defined 6.25% margin was achieved in both MA arms with pramlintide and placebo (difference -6 [95% CI -12.6, 0.5]; 1 [-3.0, 4.6]) . In adolescents, mean time in range was 51%, 55%, and 46% in the three respective arms; non-inferiority was only achieved on Fiasp and pramlintide with MA (-4 [-9.0, 1.7]) . We conclude that automated Fiasp and pramlintide delivery may alleviate CC without degrading glucose control. Disclosure E.Cohen: None. E.Palisaitis: Other Relationship; Eli Lilly and Company.
