Retifanlimab vs Serplulimab
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.

Retifanlimab
Marketed by Incyte
NCT04205812 · Phase 3 · completed
Participants were randomly assigned and double-blinded to receive retifanlimab or placebo with standard chemotherapy, with 391 in the retifanlimab group and 192 in the control group. The hard clinical primary endpoint of overall survival was met, favoring retifanlimab (hazard ratio 0.75; p=0.0042).
Next expected readout: December 2027 · NCT07219576 (registry estimate)
Serplulimab
Developed by Shanghai Henlius Biotech
NCT05807893 · Phase 2/3 · completed
The study treated 40 participants in a non-randomized, open-label, single-arm design without a comparator group. Its primary endpoint was intracranial 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 · NCT06848699 (registry estimate)
