Predictors of Initial and Sustained Glycemic and Weight Response to Tirzepatide: A Post Hoc Analysis of SURPASS-4.

ABSTRACT: This post hoc analysis assessed sustainability of lowered glycated hemoglobin (HbA1c) and weight with tirzepatide in people with type 2 diabetes and increased cardiovascular risk. Participants achieving HbA1c ≤48 mmol/mol (6.5%) or weight loss ≥10% at 52 weeks were evaluated for sustained glycemic or weight control and predictors of initial and sustained efficacy. For tirzepatide-treated participants achieving HbA1c ≤48 mmol/mol (6.5%) at 52 weeks, 75-84% sustained this until study end (median 81 weeks). Factors predicting achievement were higher tirzepatide dose, shorter diabetes duration, and lower HbA1c, higher HOMA of β-cell function (HOMA-B), metformin alone, and absence of albuminuria at baseline. Factors predicting sustained glycemic control were greater weight loss, smaller fasting
