Human Leukocyte Antigen Typing and Tumor Antigen Expression Profiling

The purpose of this screening study is to identify human leukocyte antigen (HLA) molecular subtype positive and tumor antigen target(s) positive patients. No treatment intervention will occur as part of this screening study. After diagnosis of advanced and/or solid metastatic cancers, patients will be tested for HLA molecular subtype positivity. Patients that are HLA molecular subtype positive are then assessed to determine if their tumor antigen target(s) is positive (biopsy screening). Fresh tumor tissue obtained by a biopsy for this screening study will be required. If the patient is undergoing a surgical procedure directed towards tumor or palliative treatment (e.g., a resection, debulking surgery, etc.) and has consented to the study, then fresh tissue may be collected during the procedure to avoid the patient being subjected to another biopsy. Tumor antigen targets in fresh tumor samples will be determined by an in vitro diagnostic (IVD) assay. Therefore, any remaining tumor specimens may be used for exploratory biomarker analyses and validation studies for regulatory approval. Immatics is conducting clinical studies which target patients with advanced and/or metastatic solid cancers. Patients who are HLA subtype phenotype positive and whose tumors express one or more of the tumor antigen targets of interest may be eligible for ongoing clinical studies of adoptive cell therapy (ACT).
