OBJECTIVE
To investigate the efficacy and safety of dasiglucagon, a novel stable glucagon analog in a liquid formulation, in Roux-en-Y gastric bypass (RYGB)–operated individuals suffering from postbariatric hypoglycemia (PBH).RESEARCH DESIGN AND METHODS
In a randomized, double-blind, placebo-controlled, crossover trial, 10 RYGB-operated participants with continuous glucose monitoring–verified PBH were randomly assigned to 3 trial days, each consisting of a 240-min standardized liquid mixed-meal test with the subcutaneous injection of placebo or 80 μg or 200 μg dasiglucagon.RESULTS
Compared with placebo, treatment with both 80 and 200 μg dasiglucagon raised nadir plasma glucose (PG) (placebo: 3.0 ± 0.2 mmol/L [mean ± SEM]; 80 μg dasiglucagon: 3.9 ± 0.3 mmol/L, P = 0.002; 200 μg dasiglucagon: 4.5 ± 0.2 mmol/L, P = 0.0002) and reduced time in hypoglycemia (PG <3.9 mmol/L) by 70.0 min (P = 0.030 and P = 0.008).CONCLUSIONS
Single-dose administration of dasiglucagon effectively mitigated postprandial hypoglycemia.
