Head-to-head evidence
GZR18 vs semaglutide
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.

GZR18
Developed by Gan & Lee Pharmaceuticals
NCT06737042 · Phase 2 · completed
The study randomized 326 participants and used quadruple masking with placebo and tirzepatide comparator arms; its primary endpoint was the clinical outcome of percentage change in body weight. Because the primary comparison has not yet been reported, it cannot establish whether GZR18 met its efficacy objective.
Next expected readout: June 2027 · NCT07150975 (registry estimate)

NCT03548935 · Phase 3 · completed
This was a randomized, quadruple-blind, placebo-controlled trial of 1,961 participants. At week 68, mean body-weight change was -15.6% with semaglutide versus -2.8% with placebo, and the primary comparison was statistically significant (p<0.0001), supporting strong evidence for this clinical weight-loss endpoint.
Next expected readout: October 2026 · NCT07505303 (registry estimate)
