Penpulimab 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.

Penpulimab
Marketed by Akeso
NCT03866993 · Phase 3 · completed
This randomized, placebo-controlled trial kept participants, care providers, investigators and outcome assessors blind to treatment assignment, with disease progression assessed by an independent radiology committee. Its primary endpoint, progression-free survival, was clearly met, roughly doubling median progression-free survival versus placebo plus chemotherapy.
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)
