NeXT Dx™ Test

The Personalis NeXT Dx™ Test* is a comprehensive genomic testing solution that enables oncologists to identify potential therapies and clinical trial options for cancer patients. The NeXT Dx Test is one of the first cancer diagnostic test to profile ~20,000 cancer related genes in both tumor exome and transcriptome. The clinical report documents the genetic alterations found in 248 clinically-relevant, cancer genes, as well as research data that can provide insights into emerging immunotherapy composite biomarkers of medical importance. Single nucleotide variants (SNVs), insertions/deletions (indels), copy number alterations (CNAs), and gene fusions for targeted therapy selection, as well as tumor mutational burden (TMB) and microsatellite instability (MSI) status, are reported for immunotherapy selection.

Next Generation Cancer Care: Results Unique to Your Patient

Personalis provides clinicians with clinically-focused cancer test results that maximize the chance of identifying an approved therapy or trial for each patient as well as information that can support identification of new, advanced biomarkers. These results are unique to the patient’s tumor, cover cancer genes known to be relevant in solid tumors, and provide more potential treatment options than other limited tests.

  • Improved detection of alterations in difficult-to-sequence regions of clinically important genes via proprietary methods.
  • Analysis of DNA and RNA from the same sample to enable robust identification of gene fusions.
  • Integration of immunotherapy-related biomarkers such as MSI and exome-wide TMB.
  • Determination of TMB by utilizing the gold-standard, exome-wide analysis of non-synonymous somatic mutations (SNVs and indels).
Enhanced Coverage and Uniformity

Personalis’ proprietary technology augments coverage of more complex and problematic regions not adequately addressed by standard panels.

Accurate Identification of SNVs, Indels, CNAs and Fusions

Personalis delivers variant calls through: advanced sequencing alignment tools, sophisticated algorithms, and knowledge of systematic biases inherent in sequencing technologies.

Comprehensive Analysis including MSI and Exome-wide TMB

MSI status is derived using five canonical loci (BAT25, BAT26, NR-21, NR-24, and NR-27). Exome-wide TMB is reported as the number of non-synonymous mutations per megabase.

Clinically Actionable Report

Each variant is reviewed in detail by Personalis’ clinical team, and is assessed for clinical relevance in relation to the latest evidence-based therapy recommendations and available clinical trials.

Results are presented in a clear, intuitive report so healthcare providers can rapidly understand and assess the results.

The NeXT Dx Test report delivers clinically important genomic alterations based on a comprehensive and dynamic variant classification and curation process involving multiple genetic information sources. Our database of potentially relevant therapies and clinical trial matches is continually updated based on the latest scientific and medical evidence.
