Penpulimab vs Sintilimab
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.
Sintilimab
Developed by Innovent Biologics and partners
NCT03607539 · Phase 3 · completed
This trial was randomized, quadruple-blinded, and placebo-controlled with a reasonably large sample (397 patients) and used a hard clinical primary endpoint (progression-free survival), which is a strong design overall. However, the results record reports only median PFS values and confidence intervals for each arm (8.9 vs 5.0 months) without a p-value or hazard ratio, so whether the primary comparison reached statistical significance cannot be confirmed from the data provided.
