Clin-TOF Successfully Integrated into VeriStrat® Workflow


Study Results, Presented at MSACL, Advance Biodesix®/Bioyong Agreement

Study results presented today demonstrate the feasibility of running the VeriStrat® test on Bioyong’s Clin-TOF platform, and provide a basis for validating and deploying a version of the VeriStrat® test in Greater China. The data were presented in a poster at the ninth annual conference of the Association for Mass Spectrometry: Applications to the Clinical Lab (MSACL) in Palm Springs, California.

Biodesix (Boulder, CO, USA) and Bioyong Technology Company Ltd. (Beijing, China) announced earlier this month that they have entered into an agreement whereby Bioyong will develop and commercialize a version of Biodesix’s VeriStrat® proteomic blood test for clinical use in Greater China, with potential expansion into other Asia-Pacific countries.

For the study, Bioyong's Chinese FDA (CFDA)-cleared MALDI-TOF device was integrated into the VeriStrat® assay workflow. Biodesix used the same tiered qualification approach that it employs in its CLIA/CLEP-certified laboratory to analyze multiple sample sets with the Clin-TOF instrument. Across a total of 87 samples, concordance was 100%.

“The data from this study show that Bioyong’s Clin-TOF generates high-quality spectra and can support the VeriStrat® assay,” said Biodesix senior scientist Nicholas Dupuis, Ph.D. “Based on these results, we are confident of validating a version of the VeriStrat® test for the China market.”

“We are happy that our Clin-TOF platform has passed Biodesix’s strict qualification requirements,” said Dr. Ma, the founder and chairman of Bioyong. “This positive result gives us confidence that our plan to bring a version of the VeriStrat® test into clinical use in Greater China will be successful.”

With nearly 850,000 new lung cancer diagnoses predicted in 2020, China represent approximately 37% of new cases expected worldwide.

About the VeriStrat® test:

Biodesix’s VeriStrat® test is a predictive and prognostic blood-based proteomic test for patients with non-small cell lung cancer. The test is used to assess disease aggressiveness by characterizing host response to the tumor, classifying patients as either VeriStrat® Good or VeriStrat-Poor.

About Biodesix
Biodesix® is a molecular diagnostics company advancing the development of innovative blood tests in oncology to enable precision medicine. Biodesix discovers, develops and commercializes multivariate protein and genomic diagnostic blood tests, including the GeneStrat® and VeriStrat® tests, that deliver results within 72 hours. The company is changing the standard of care by providing physicians with diagnostic tests for better therapeutic guidance, more accurate prognosis and enhanced disease monitoring to improve patient outcomes. At the forefront of precision medicine, Biodesix is developing new blood tests to identify patients who may benefit from immunotherapies. In addition to developing novel diagnostics independently, the company partners with biotechnology and pharmaceutical companies to develop companion diagnostics for use with therapeutic agents.
