The 22C3 and SP142 assays show analytical concordance for overall PD-L1 status but significant variability in IC scoring. Given the variability in PD-L1 expression across UC-s, precise characterization of both TC and IC staining per assay is crucial. These findings support incorporating UC-s subtype and assay-specific PD-L1 profiles into routine diagnostics to optimize immunotherapy decisions.
P3, N=673, Terminated, Novartis Pharmaceuticals | Trial completion date: May 2026 --> Jan 2026 | Active, not recruiting --> Terminated; Results of primary analysis showed addition of canakinumab to combination treatment did not improve tumor response or overall survival; the decision to stop the trial was not due to safety concerns
Only three cases exhibited copositivity for both ALK and ROS1, with an odds ratio of about 1.17 (95% CI: 0.20-6.58) and a p-value of approximately 0.95, indicating no significant association. Conclusion The expression of PD-L1 is independent of ALK and ROS1 alterations in lung adenocarcinoma, suggesting that these biomarkers do not significantly correlate with one another.
