GZR18 vs orforglipron
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)
orforglipron · Foundayo
Marketed by Eli Lilly
NCT05803421 · Phase 3 · completed
The study is randomized and active-controlled with a large sample of 2,749 participants, but it is open-label rather than blinded. Its primary endpoint is a hard clinical cardiovascular outcome; however, the comparison cannot be judged because no results are currently available.
Next expected readout: February 2027 · NCT06672549 (registry estimate)
