TROP2 NMR Concordance Study

Sponsor: AstraZeneca

View on ClinicalTrials.gov

Summary

This is a two-stage, multi-center study to compare concordance of Local solution and Mixed solution with a Reference solution in testing TROP2 NMR in untreated advanced NSCLC patients, as well as clinical application and robustness in real world labs. TROP2 NMR testing by QCS is composed of three main components: IHC assay, digital scanner and QCS algorithm. This study mainly focuses on end-to-end comparisons from different solutions or real-world labs. TROP2 NMR status results will be compared and the end-to-end concordance between solutions or labs will be assessed by PPA, NPA, and OPA. Three different solutions will be included in this study: Reference solution\\Local solution\\Mixed solution. Stage 1 will evaluate concordance of Local solution and Mixed solution with Reference solution in a central lab. Totally about 600 samples will be tested using Local solution, Mixed solution and Reference solution. When solutions concordance in stage 1 is achieved, the study will proceed to stage 2. Stage 2 will then assess the robustness and reproducibility of different solutions in real world pathology labs. About 1,000 TROP2 NMR positive (TROP2 NMR+) and 1,000 TROP2 NMR negative (TROP2 NMR-) samples will be identified by central lab using Reference solution, then these status-known samples will be distributed to approximately 50 participating site labs with 20 TROP2 NMR+ and 20 TROP2 NMR- per site, and subsequently tested at site labs in a blinded manner using Reference solution, and/or Local solution and/or Mixed solution, depending on Stage 1 results.

DEVICE

Reference solution

Reference solution incorporates a TROP2 IHC assay, scanner and image analysis RUO algorithm into a solution for TROP2 NMR testing that has been well-established and validated. Pathologists may interpret the results; they may also perform quality control steps and negative selection of nontumor areas, if needed.

DEVICE

Mixed solution

Mixed solution for TROP2 NMR testing is defined as TROP2 IHC staining using identical clone with Reference, and stained slides will be transformed into digital images using KFBIO scanner (KF-PRO series). Images will be analysed by QCS algorithm RUO and the pathologist role is same as Reference solution.

DEVICE

Local solution

Local solution for TROP2 NMR testing is defined as TROP2 IHC staining using the identical assay with Reference, and stained slides will be transformed into digital images using KFBIO scanner (KF-PRO series). Images will be analysed by QCS algorithm RUO and the pathologist role is same as Reference solution.
