Personalis, Inc. Announces Integration of New ImmunoID NeXT Platform™ Features in Latest Expansion of Immuno-Oncology Biomarker Discovery Applications

Through the deep interrogation and analysis of approximately 20,000 genes in both DNA and RNA, ImmunoID NeXT consolidates multiple biomarker assays into one, providing a multidimensional view of the tumor- and immune-related components of the tumor microenvironment from a single sample. The platform is an end-to-end solution for immuno- and precision oncology biomarker discovery applications, and in addition to these new features, it simultaneously enables the analysis of:

• Tumor escape and primary/acquired drug resistance mechanisms
• Adaptive immune cell receptor clonotypes and repertoire clonality
• Innate immune cells
• Predicted tumor-specific neoantigens
• HLA typing and somatic mutations
• Neoantigen load and tumor mutational burden (TMB)
• Microsatellite instability (MSI) status
• Somatic single nucleotide variations (SNVs), insertions/deletions (indels), gene fusions, and copy number alterations (CNAs)
• Germline variants

Personalis CSO, Richard Chen, MD, said, “With the integration of these additional capabilities, we’re continuing to demonstrate our commitment to maximizing the biological insights that can be derived from single tumor samples, which are often limited in availability. While the roles of the adaptive immune cells and oncoviruses are well documented in many cancer types, HLA LOH has emerged as an important, potential resistance mechanism to immunotherapy. We’re excited to be one of the first commercial providers of this analysis as part of ImmunoID NeXT™, the premier tumor immunogenomics platform for comprehensive biomarker evaluation in both solid and hematologic cancer indications.”
