Abstract

Tirzepatide delayed (GE) in participants with type 2 diabetes after multiple doses.

  • In diet-induced obese mice, tirzepatide delayed GE similarly to semaglutide, but this effect disappeared after 2 weeks.
  • GIP analogue alone did not influence GE or enhance GLP-1's impact on GE.
  • In healthy participants, the GE delay from a single dose of tirzepatide or dulaglutide lessened after multiple doses.
  • Participants with type 2 diabetes experienced a persistent GE delay with an escalation schedule of tirzepatide.
