Inclusion criteria

Inclusion criteria: To be eligible for staining with the VENTANA PD-L1 (SP263) CDx Assay in this diagnostic study, a specimen must meet all of the following criteria: 1. It must be a formalin-fixed, paraffin-embedded (FFPE) NSCLC tumor specimen submitted for Study GCT1046-06 and processed in accordance with standard practice; 2. It must contain sufficient tumor tissue for interpretation at the discretion of the reviewing pathologist; and 3. If an FFPE tissue block is unavailable, unstained FFPE slides can be submitted.

Exclusion criteria

Exclusion criteria: A specimen will be excluded from staining with the VENTANA PD-L1 (SP263) CDx Assay in this diagnostic study based on any of the following: 1. It is known to be fixed in 95% alcohol or other alcohol-based fixative, alcohol-formalinacetic acid (AFA), or PREFER; 2. It is a fine needle aspirate (FNA) or cytology specimen; 3. It consists of tissue containing bone that has been decalcified; or 4. Cut slides were prepared more than 12 months prior to staining.

Design outcomes

Primary

MeasureTime frame
Primary Endpoint: The primary endpoint for the clinical performance study is the primary efficacy endpoint defined in the Study GCT1046-06 protocol: overall survival (OS). Primary Acceptance Criteria: The clinical performance of VENTANA PD-L1 (SP263) CDx Assay will be considered acceptable if the primary efficacy analysis of OS in the Study GCT1046-06 supports the efficacy of acasunlimab (GEN1046) in combination with pembrolizumab treatment in the population selected using the assay.

Secondary

MeasureTime frame
Additional Endpoints: Additional endpoints for this study include the following staining performance measures of the VENTANA PD-L1 (SP263) CDx Assay: - Initial and final staining acceptability rates for the assay - Initial and final tissue morphology acceptability rates for the assay - Initial and final background acceptability rates for the assay There are no pre-determined acceptance criteria associated with these additional endpoints.
