Gefitinib vs Icotinib
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.

Gefitinib
Marketed by AstraZeneca
NCT00020709 · Phase 3 · completed
This was a large, randomized, double-blind, placebo-controlled trial with 840 participants and hard clinical primary endpoints of overall survival and progression-free survival. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Next expected readout: October 2026 · NCT03333343 (registry estimate)
Icotinib
Developed by Betta Pharmaceuticals Co.
NCT01040780 · Phase 3 · completed
This was a randomized, quadruple-blind, active-controlled trial with 200 participants assigned to icotinib and 199 to gefitinib, and its primary endpoint was the clinical measure of progression-free survival. Although the reported median favored icotinib, the statistical significance of the primary comparison is not stated, so the result is unclear rather than definitively positive.
Next expected readout: December 2030 · NCT06955325 (registry estimate)
