Head-to-head evidence
Saxagliptin vs SP2086
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.
Type 2 Diabetes
Shared mechanism: DPP-4 · full Type 2 Diabetes pipeline
Saxagliptin · Onglyza
Marketed by AstraZeneca and partners
NCT00121667 · Phase 3 · completed
Large randomized, double-blind, placebo-controlled phase 3 trial (743 treated participants across three saxagliptin doses and one placebo arm, all on background metformin). The primary endpoint was change from baseline in hemoglobin A1c at Week 24, an accepted hard glycemic measure for type 2 diabetes, and every saxagliptin dose showed a statistically significant improvement versus placebo (adjusted differences of -0.73, -0.83, and -0.72 percentage points, each p<0.0001). Because the trial was adequately powered, double-blind, and placebo-controlled, and the primary comparison was met, this is strong evidence for saxagliptin's efficacy.
Next expected readout: October 2026 · NCT07033585 (registry estimate)
SP2086
Developed by Jiangsu Hengrui Pharmaceuticals
NCT01970033 · Phase 3 · status unknown
This is a large, randomized, quadruple-blind, placebo-controlled trial using the standard glycemic control measure for diabetes as its primary endpoint, but no results have been posted yet, so whether the drug lowered HbA1c more than placebo is unknown. (Independently confirmed by a second model, in-session-confirm:claude-opus-20260822.)
