Inclusion criteria

Inclusion criteria: 1. It must consist of archival or fresh tumor tissue submitted for patient enrollment screening for Study BNT323-01;  2. It must be fixed in 10% neutral buffered formalin and consist of a FFPE tissue block or as unstained slides with approximately 4-µm thick sections cut from such a block;  3. It must appear to contain sufficient tissue for interpretation, as determined by a site pathologist’s review of a serially adjacent or nearly serially adjacent slide stained with hematoxylin and eosin (H&E); and  4. The sections for staining must have been cut within the currently documented cut-slide stability (CSS) window in effect at the time of staining.

Exclusion criteria

Exclusion criteria: 1. It is a fine needle aspirate (FNA), any other cytological specimen, or a decalcified bone metastasis

Design outcomes

Primary

MeasureTime frame
•  Primary: Progression-free survival (PFS) by blinded independent central review (BICR) according to response evaluation criteria in solid tumors (Response Evaluation Criteria in Solid Tumors-RECIST 1.1) in participants with HER2- expressing recurrent endometrial cancer and prior immune checkpoint inhibitor treatment. •  Key Secondary: PFS by BICR according to RECIST 1.1 in participants with HER2-expressing recurrent endometrial cancer.  

Secondary

MeasureTime frame
• The secondary endpoint for this study is the final overall staining acceptability rate for the VENTANA HER2/neu (4B5) IUO Assay.
