Tirzepatide Treatment and Associated Changes in β-Cell Function and Insulin Sensitivity in People With Obesity or Overweight With Prediabetes or Normoglycemia: A Post Hoc Analysis From the SURMOUNT-1 Trial

Diabetes CarePublished Secondary analysis of the SURMOUNT-1 randomised trial

Authors' conclusion

In adults with obesity/overweight without type 2 diabetes, tirzepatide treatment was associated with improved β-cell function and insulin sensitivity, partly independent of weight reduction.

Study context

Population
Adults with BMI ≥27 kg/m² without diabetes, with prediabetes or normoglycemia at baseline
Participants
2,539 adults
Comparison
Tirzepatide vs placebo

Primary result

As reported in the abstract

Insulin sensitivity and β-cell function
  • Tirzepatide associated with body weight reduction and improvements in insulin sensitivity and β-cell function measures, overall and in prediabetes or normoglycemia
  • In multivariate regression, insulin sensitivity improvements associated mostly with weight reduction and partly with tirzepatide; β-cell function enhancement mostly associated with tirzepatide
