Head-to-head evidence
amycretin vs GZR18
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.

amycretin
Developed by Novo Nordisk
NCT06064006 · Phase 2 · completed
The study was randomized, quadruple-masked, and placebo-controlled, with 125 participants, providing a meaningful controlled design. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
This trial's registered primary endpoint was safety (treatment-emergent adverse events); the figures shown are its prespecified secondary weight-change endpoints as published in The Lancet.
Next expected readout: December 2027 · NCT07587710 (registry estimate)
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)
