Head-to-head evidence
Sintilimab vs Toripalimab
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.

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.

Toripalimab
Marketed by Coherus BioSciences, Inc. and partners
NCT03856411 · Phase 3 · completed
This randomized, quadruple-blind, placebo-controlled trial of 465 patients met its primary endpoint: median progression-free survival was 8.4 months with toripalimab plus chemotherapy versus 5.6 months with placebo plus chemotherapy, a highly statistically significant improvement.
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.
Next expected readout: December 2026 · NCT06426511 (registry estimate)
