Tirzepatide (TZP), a novel, once-weekly GIP/GLP-1 receptor agonist, significantly reduced liver fat content (LFC) and volumes of visceral and abdominal subcutaneous adipose tissue (VAT and ASAT) vs insulin degludec in a subpopulation of patients in the SURPASS-3 phase 3 trial. This post-hoc analysis evaluated changes from baseline to Week 52 in these outcomes and other clinical and laboratory parameters in TZP-treated patients achieving or not achieving normoglycemia (HbA1c <5.7%) at Week 52.

LFC, VAT and ASAT volumes were assessed with MRI prior to randomization and at Week 52 in insulin-naïve patients with type 2 diabetes inadequately controlled on metformin with/without SGLT-2i and fatty liver index ≥60 at baseline. Analyses used pooled data from all TZP arms (5, 10, and 15 mg).

Patients achieving HbA1c <5.7% were slightly younger and had lower baseline HbA1c and VAT vs those not achieving HbA1c <5.7%. Substantial reductions in LFC, VAT and ASAT volumes, weight, HbA1c, and overall improvement in lipids profile were observed in both subsets of patients (Table). Among patients achieving HbA1c <5.7% and ≥5.7%, respectively, 56% and 27% achieved LFC <6%, and 91% and 64% achieved ≥30% reduction in LFC.

In summary, in TZP-treated patients, changes in LFC, VAT and ASAT, and lipids were more pronounced in those achieving normoglycemia.
