• We explored the effects of tirzepatide (TZP) on counter-regulatory response during a hypoglycemic clamp. Patients with type 2 diabetes (N=42) were randomized to TZP (15 mg) or placebo (PBO) for 12 wk, in a crossover design, with a wash-out period of 8 to 12 wk. The primary objective was the change in glucagon (GCG) during clamp-induced hypoglycemia (HG) from plasma glucose (PG) 100 mg/dL to nadir PG (45 mg/dL). Secondary measures were changes in other counter-regulatory hormones, insulin, and C-peptide during clamp-induced HG and PG recovery from nadir PG to 72 mg/dL. Time to recovery and HG symptom scores were assessed. At 12 wk, HbA1c change from baseline was -1.5% with TZP vs +0.5% with PBO. Increases in GCG from PG 100 mg/dL to nadir PG and during recovery did not differ between treatments (p=0.756 and p=0.565, respectively) (Table). Growth hormone and adrenaline responses did not differ between treatments, while increases in cortisol and noradrenaline responses were delayed with TZP, which explains a lower HG symptom score with TZP vs PBO at nadir (p=0.007). The proportion of patients aware of HG did not differ between treatments. Mean time to recovery from HG was 47 min with TZP and 43 min with PBO (p=0.002); however, nadir PG was lower with TZP (44 vs 47 mg/dL; p=0.015). In conclusion, the response of glucagon to hypoglycemia is maintained with TZP.
