Summary
NeXT Dx is a comprehensive genomic profiling assay that accurately detects various cancer alterations, including single nucleotide variants, indels, copy number alterations, and gene fusions, aiding therapy and clinical trial selection for solid tumors.
Area of Science:
- Genomic Medicine
- Oncology
- Molecular Diagnostics
Background:
- Comprehensive genomic profiling (CGP) is crucial for personalized cancer therapy and clinical trial matching.
- Accurate detection of diverse genomic alterations is essential for effective treatment selection in solid tumors.
Purpose of the Study:
- To describe the analytic validation of the NeXT Dx assay for comprehensive genomic profiling.
- To evaluate the assay's performance in detecting various genomic alterations in solid tumors.
Main Methods:
- NeXT Dx utilizes whole exome and whole transcriptome sequencing with proprietary Accuracy and Content Enhanced technology.
- Patient-specific normal samples enhance somatic and germline variant calling.
- RNA sequencing improves gene fusion detection accuracy.
Main Results:
- NeXT Dx demonstrated high analytic sensitivity for SNVs (99.4%), indels (98.2%), CNAs (98.0%), and fusions (95.8%).
- Overall analytic specificity exceeded 99.0%.
- The assay is validated for 401 cancer-associated genes with potential for future expansion.
Conclusions:
- NeXT Dx provides accurate and comprehensive genomic profiling for solid tumors.
- The assay supports informed therapy and clinical trial selection for cancer patients.
