Bionano Genomics announces release of version 6.2 of its Nxclinical software with significant new capabilities for cancer research applications including HRD analysis
Bionano Genomics, Inc. (BNGO), pioneer of optical genome mapping (OGM) solutions on the Saphyr® system and provider of NxClinical™ software, the leading solution for visualization, interpretation and reporting of genomic data, today announced the launch of an integrated genomic scar analysis for homologous recombination deficiency (HRD) in the version 6.2 software release of NxClinical. This feature provides a comprehensive, consistent, and automated analysis of biomarkers from next-generation sequencing (NGS) and microarray data that can help clinical researchers stratify therapeutic response across multiple tumor types.
Integrated HRD genomic scarring has been introduced into this latest version of NxClinical software, developed by BioDiscovery, to measure genomic instability in a platform-agnostic way. This analysis allows cancer researchers to gain important insights from genetic data they are already generating from widely available array and sequencing assays, including several from Illumina, ThermoFisher, and Agilent.
HRD represents a disruption to the normal cellular pathway that repairs double-stranded DNA breaks, which consequentially results in acquired chromosomal breakage. Clinical research has shown that cells with HRD are more sensitive to certain therapies, like Poly(ADP-Ribose) Polymerase (PARP) inhibitors and other DNA repair-targeting drugs; therefore, a measurement of HRD may be an effective pharmacogenetic biomarker across various tumor types.
NxClinical software includes measurement of three genomic scars – Loss of Heterozygosity (LOH), Telomeric Allelic Imbalance (TAI), and Large-Scale State Transitions (LST) – that signal large-scale genomic instability. The automation of genomic scar analysis can simplify and expand access to HRD status assessment of cancer samples and enhance the clarity and transparency of tumor profiles. This analysis has the potential to drive improved stratification for clinical trials and provide pharmacogenomic-driven decisions in a precise manner that is relevant to the underlying biology of the cancer under investigation.
Current tools for assessing HRD status are limited to targeted detection of point mutations in HR genes predicted to be causative of HRD or cannot detect abnormalities across the entire genome. NxClinical software can help resolve this limitation by providing a genome-wide scarring approach coupled with integrated SNV analysis of HR genes that may reveal critical insights to tumor biology. The proprietary analysis method assesses copy number and allelic changes across the genome to identify specific quantifiable signatures of HRD genomic instability.
Related to this new functionality, Bionano is participating as an industry partner with the nonprofit organization Friends of Cancer Research on a research project to harmonize the use of HRD as a biomarker to guide certain treatment types. Diagnostic Laboratory Services (Hawaii) will serve as the collaborator and laboratory testing site, leveraging the HRD measurement capabilities of NxClinical software.
“Scientific interest in tumor HRD status is high, given its potential to serve as a routine and effective biomarker for a wide range of cancer types,” stated Soheil Shams, PhD and chief informatics officer of Bionano. “We believe NxClinical 6.2 software offers an unparalleled visualization of the consequences of HRD and can streamline HRD analysis across different platforms and clinical research settings. Our goal is ultimately to improve cancer care by providing clinical researchers better tools to confidently adopt HRD analysis into their practice, without disruption to their current workflows.”
Erik Holmlin, PhD, president and chief executive officer of Bionano, commented, “With this release of NxClinical 6.2 software, we are significantly expanding the genome analysis capabilities available to the clinical and translational research communities. One of the key steps towards eliminating cancer is for researchers to better identify targeted treatments based on tumor biology, and having an automated, consistent, and comprehensive HRD analysis may unlock new insights and treatments for elevating human health. Once we have successfully integrated OGM data capabilities into NxClinical software, we expect structural variants uniquely identified by OGM to enhance the performance of our HRD analysis capabilities.”
