Head-to-head evidence
Aflibercept vs HLX04-O
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.

NCT00509795 · Phase 3 · completed
The trial randomly assigned 1,217 participants and used quadruple blinding with ranibizumab as an active comparator. Its hard clinical primary endpoint—maintaining vision at week 52—met the prespecified non-inferiority criterion for all three aflibercept regimens, supporting a strong evidence grade.
Next expected readout: December 2026 · NCT06856577 (registry estimate)
HLX04-O
Developed by Shanghai Henlius Biotech
NCT04740671 · Phase 3 · completed
The trial randomized 410 participants to HLX04-O or the active comparator ranibizumab and masked both participants and investigators. Its primary clinical endpoint was the mean change in best-corrected visual acuity at Week 36, but no statistical comparison or outcome result is available yet.
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
