Head-to-head evidence
elecoglipron 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.
Obesity
Shared mechanism: GLP-1 receptor · full Obesity pipeline
elecoglipron
Developed by AstraZeneca
NCT06579092 · Phase 2 · completed
This randomised, triple-blind, placebo-controlled trial in 310 adults living with obesity or overweight reported a 10.5% reduction in body weight on elecoglipron 75 mg against 0.6% on placebo at 26 weeks. Percent weight change is the measure regulators accept as the primary efficacy endpoint in obesity.
Next expected readout: April 2028 · NCT07775404 (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)
