The findings, published in Nature Communications, are the latest research leveraging machine learning to improving the efficiency and accuracy of genomics. The study was co-authored by researchers from NuProbe USA, Rice University, and Microsoft Research UK.
Research published in Nature Biomedical Engineering demonstrates NuProbe’s technology can enable detecting SNVs in DNA with a VAF of ≤0.02% using a sequencing depth of only 250x.
The VarMap Pan-Cancer NGS Panel uses the quantitative blocker displacement amplification technology to enrich, detect, and quantitate over 6500 mutations and indels in 61 clinically relevant genes. The panel can be used on cfDNA samples to detect mutations down to 0.1% variant allele frequency (VAF) using only 1 million NGS reads. The panel can also be applied to FFPE tumor samples or other cellular samples for minimum residual disease (MRD) detection, detecting mutations down to 0.01% VAF.
The lead investors for this financing round are BioTrack Capital and Yonghua Capital. The proceeds will be used to expand the commercial team in both the US and China, develop new NGS products, and file for regulatory approval in China for NuProbe’s clinical products.
NuProbe and Weigao Group will apply NuProbe’s proprietary Blocker Displacement Amplification (BDA) technology to developing a liquid biopsy NGS panel for non-small cell lung cancer (NSCLC). The product will be compatible with the desktop NGS instruments, and the companies plan to later apply for in vitro diagnostic (IVD) registration with NMPA, China’s equivalent of FDA.
The first, Non-Extensible Oligonucleotides (NEO), will allow NuProbe to provide much more rapid development of customized NGS panels, with turnaround time of less than 4 weeks. The second, Linear DNA Assembly (LDA) technology, improves the effective throughput of nanopore sequencing by up to 10-fold for short DNA, such as DNA extracted from FFPE tumor tissues and cell-free DNA from peripheral blood. Concurrently, NuProbe announces the launch of its new VarMap™ Nanopore product line.
Two additional world-renowned oncologists will join NuProbe’s clinical advisory board: Amir A. Jazaeri, M.D., from the University of Texas MD Anderson Cancer Center and Abhijit Patel, M.D., Ph.D., from Yale University School of Medicine
NuProbe and QIAGEN will collaborate to develop next-generation sequencing (NGS)-based cancer diagnostic tests for non-invasive liquid biopsy. NuProbe and QIAGEN will explore integrating their two amplicon-based enrichment and sequencing technologies: NuProbe’s proprietary Blocker Displacement Amplification (BDA) technology and QIAGEN’s Single Primer Extension (SPE) technology,
Oxford Nanopore has licensed NuProbe’s Blocker Displacement Amplification technology globally for undisclosed consideration. The technology combination offers the potential to combine Oxford Nanopore sequencing, which offers real-time, rapid turnaround, scalable sequencing of any length DNA or RNA fragments, with the NuProbe technique to enable greater detection sensitivities and quantification of somatic mutations at less than 5% allele frequency.
