Head-to-head evidence
Sasanlimab 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.
Non-Small Cell Lung Cancer
Shared mechanism: PD-1 · full Non-Small Cell Lung Cancer pipeline
Sasanlimab
Developed by Pfizer
NCT04181788 · Phase 1/2 · completed
Phase 1/2 open-label study in advanced malignancies (155 participants). The primary endpoints are dose-limiting toxicities and pharmacokinetic exposure, reported descriptively; no efficacy hypothesis was tested as a primary comparison.
Next expected readout: October 2026 · NCT06447662 (registry estimate)
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.
Next expected readout: December 2026 · NCT06198907 (registry estimate)
