Cancer Genomics Consortium Members Demonstrate 100% Concordance Between Bionano Saphyr and Gold Standard Cytogenetics in Leukemia

Saphyr identifies all variants detected by the standard of care in cytogenetics in over 100 leukemia samples


SAN DIEGO, May 19, 2020 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (NASDAQ: BNGO) announced that in an online presentation hosted by the Cancer Genomics Consortium (CGC) on May 12, 2020, Dr. Brynn Levy from Columbia University and Dr. Rashmi Kanagal-Shamanna from the MD Anderson Cancer Center each presented updates on their work showing 100% concordance between Bionano Genomics’ optical mapping technology and current gold standard cytogenetic methods.

In his presentation, Dr. Levy reported on a blinded, prospective study comparing the results generated by Bionano’s Saphyr instrument to results from routine clinical testing in CLIA laboratories using current gold standard cytogenetic techniques. On 91 samples from patients with Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL) that passed inclusion criteria, Bionano was 100% concordant with karyotyping results. Additionally, Dr. Levy illustrated concordance with chromosomal microarray (CMA) for both the size and the breakpoints of identified aberrations in several cases of ALL and AML. Overall, Dr. Levy noted that Saphyr provided “Tremendous and remarkable concordance with traditional cytogenomic analyses for karyotype, FISH and CMA.”

Dr. Levy described how the current gold standard of leukemia testing requires karyotyping on all samples. When requested by the physician, multiple rounds of FISH with different FISH probes, and/or chromosomal microarray are run in addition. CMA provides a genome-wide scan for copy number variants (CNVs) but cannot detect balanced structural rearrangements or map chromosome structure of large imbalances.

The study run by Dr. Levy is part of the Cancer Genomics Research Network and its members lead cytogenetics departments from Harvard Medical School, PathGroup, Columbia University, Penn State College of Medicine, Mayo Clinic, Seattle Cancer Care Alliance, MD Anderson Cancer Center, Augusta University and Legacy Laboratory Services.

In a second presentation, Dr. Rashmi Kanagal-Shamanna from the MD Anderson Cancer Center gave an update on her study involving 100 samples of patients suffering from Myelodysplastic Syndrome (MDS), a precursor to AML. The clinical management of patients with MDS is largely determined by the number of structural aberrations detected, and therefore a single technology, like Saphyr, that is able to detect all CNVs and balanced rearrangements is desirable. Before the closure of Dr. Shamanna’s lab due to the COVID-19 crisis, she analyzed 13 samples using Saphyr. A combined 39 aberrations that passed inclusion criteria were detected by karyotyping, and all of those variants were detected by Saphyr. Additionally, there was 100% concordance between Saphyr and calls made with CMA. Importantly, Bionano identified critical rearrangements important for prognostication of the disease and identified many novel aberrations that change the R-IPSS risk score, which would alter therapeutic management. 

“The tremendous progress made in the two studies reported here add to similar results of a study on 48 leukemia genomes from Radboud University Medical Center in the Netherlands. The three studies each demonstrate 100% concordance between Bionano’s genome imaging technology and all major cytogenetic methods combined in over 150 leukemia samples,” comments Erik Holmlin, PhD, CEO of Bionano Genomics. “These three studies involving the ten renowned institutes provide significant scientific support for our belief that Saphyr is the future of cytogenetic analysis, and that our technology is ready for widespread clinical adoption.”

Both aforementioned studies are expected to be submitted for publication this quarter. The online presentation from the CGC is available for viewing at https://bionanogenomics.com/library/webinars/.

About Bionano Genomics

Bionano is a genome analysis company providing tools and services based on its Saphyr system to scientists and clinicians conducting genetic research and patient testing. Bionano’s Saphyr system is a platform for ultra-sensitive and ultra-specific structural variation detection that enables researchers and clinicians to accelerate the search for new diagnostics and therapeutic targets and to streamline the study of changes in chromosomes, which is known as cytogenetics. The Saphyr system is comprised of an instrument, chip consumables, reagents and a suite of data analysis tools, and genome analysis services to provide access to data generated by the Saphyr system for researchers who prefer not to adopt the Saphyr system in their labs.
