An ongoing IRB-approved multi-site study evaluated 331 sets of individual samples from 202 unique samples at 5 sites for provisional measurements of key parameters:
- Standard of Care Agreement (SOC) – 97.7% [214 out of 219 samples]
- Partially concordant with SOC – 2.3% [5 out of 219 samples]
- SOC concordance for pathogenic variant calls – 100% [219 out of 219 samples]
- Chromosome microarray concordance (MAC) – 100% [103 out of 103 samples]
- First pass success rate for GMOs – 94% [311 out of 331 samples]
- Reproducibility of analytical QC from one site to another – 98.8% [171 out of 173 replicates]

SAN DIEGO, January 10, 2022 (GLOBE NEWSWIRE) – Bionano Genomics, Inc. (BNGO), pioneer of optical genome mapping (GMO) solutions on the Saphyr® N system and providerXClinical ™, the leading software solutions for visualization, interpretation and communication of genomic data, today announced the publication of the first reading of the ongoing clinical trial designed to support the establishment of the GMO in the standard of care (SOC) framework in the diagnosis of genetic diseases for postnatal patients. This publication reports on the diagnostic component of postnatal genetic diseases of Bionano’s study to assess GMOs as an alternative to SOC workflows in four key clinical areas: prenatal and postnatal genetic diseases, hematologic malignancies and solid tumors. . The studies will compare GMO to SOC, including concordance, reproducibility, technical success rates, turnaround time (TAT), diagnostic yield, health economics, and patient outcomes. This first intermediate reading is designed to assess parameters related to analytical performance in key areas of technical performance and reproducibility of the GMO.
“The process of establishing a trial program with a consortium like this is made possible by knowledgeable principal investigators and leading sites,” commented Alka Chaubey, PhD, FACMG, Chief Medical Officer of Bionano . “We believe the trial has started well, with a total of 813 subjects enrolled to date and, as the intermediate reading of 202 subjects and 331 samples shows, GMO has performed well. We look forward to investigators proceeding with the remaining samples and assessing other critical parameters such as comparative diagnostic yields, turnaround times, and economic health impacts. “
Study design
The study is an Institutional Review Board approved, double-blind, multicenter trial with 202 clinical research subjects analyzed in a total of 331 sample sets. All samples had been previously tested with traditional methods such as karyotyping, fluorescence in situ hybridization (FISH) and chromosome chip (CMA). Samples were from cases with genetic diagnosis (152), cases without genetic diagnosis (6) and controls (44).
The sites carrying out the study and their main investigators are as follows:
- University of Rochester Medical Center (Dr M. Anwar Iqbal)
- Medical College of Wisconsin (Dr Ulrich Broeckel)
- Columbia University Medical Center (Dr Brynn Levy)
- Greenwood Genetic Center (Dr Roger Stevenson)
- Georgia Medical College, Augusta University (Dr Ravindra Kolhe)
- Praxis Genomics (Dr Peter L. Nagy)
- University of Iowa Health Clinics (Dr. Aaron Bossler)
Main conclusions
This publication describes GMO performance metrics such as first pass success rate and site-to-site, operator-to-operator, and cycle-to-cycle reproducibility for the very first. times and for the largest number of samples studied with GMOs to date.
The main findings for the technical parameters were reported as follows:
- Agreement with SOC – 97.7% [214 out of 219 samples]
- Partially concordant with SOC – 2.3% [5 out of 219 samples]
- SOC concordance for pathogenic variant calls – 100% [219 out of 219 samples]
- Agreement with CMA – 100% [103 out of 103 samples]
- First pass success rate for GMOs – 94% [311 out of 331 samples]
- Reproducibility of analytical QC from one site to another – 98.8% [171 out of 173 replicates]
- Reproducibility of pathogenic variant calls from one site to another – 100% [173 out of 173 replicates]
Key points to remember
The publication concluded that these results demonstrate high technical performance of the GMO workflow from DNA isolation to data analysis. The authors reported that the performance of the replicates demonstrates the reproducibility of the GMO, suggesting that it can be adapted and validated. The authors further pointed out that GMO is not limited to the analysis of copy number variation, but can also solve balanced structural rearrangements, repeated size expansions like FMR1 and repeat the contractions as D4Z4. In summary, the authors concluded that a unique approach, like GMO, can enable genetics labs to deliver rapid results with a cost-effective solution, which can benefit both the lab and those affected.
“The OGM community is evaluating the entire workflow. The performance we have seen is in line with our expectations and we are delighted with this publication announcing that GMO is performing well at multiple sites, ”commented Erik Holmlin, PhD, President and CEO of Bionano. “5 I look forward to seeing the outcome for all test subjects on the remaining endpoints. We believe we can change the standard of care in genetic testing with GMOs and these studies can provide important supporting data. “
