Semaglutide (sema) 0.5 mg is part of type 2 diabetes (T2D) standard of care as initial maintenance dose. While there has been a study conducted on TZP and sema 1.0 mg, showing TZP superiority, currently there is no head-to-head study comparing TZP and sema 0.5 mg. Therefore, the objective of this analysis was to evaluate the efficacy and safety of TZP and sema 0.5 mg using adjusted indirect comparisons.

Adjusted indirect comparisons were performed using the Bucher method to compare the relative efficacy and safety of TZP 5, 10, 15 mg and sema 0.5 mg via a common comparator (sema 1.0 mg) based on trial results from SURPASS-2 (TZP vs sema 1.0 mg) and SUSTAIN 7 (sema 0.5 and 1.0 mg vs dulaglutide 0.75 and 1.5 mg).

All TZP doses showed statistically significant greater reductions in HbA1c, weight and BMI from baseline to week 40 compared to sema 0.5 mg (Figure).

TZP demonstrated a comparative safety profile for adverse events (AEs) but patients had statistically significant greater odds of treatment discontinuations due to AEs for TZP 10 and 15 mg. All TZP doses demonstrated no statistically significant differences vs sema 0.5 mg in the odds or likelihood of gastrointestinal AEs.

In these adjusted indirect comparisons the extent of differences between TZP and sema 0.5 mg regarding HbA1c and weight reductions provide insights on their comparative effectiveness in the absence of a head-to-head study.
