CARLSBAD, CA — (BUSINESS WIRE) — Thermo Fisher Scientific, the world leader in serving science, today announced the U.S. Food and Drug Administration (FDA) has approved the Oncomine™ Dx Express Test on the Ion Torrent™ Genexus™ Dx Integrated Sequencer as an in vitro diagnostic (IVD) assay for use as a companion diagnostic (CDx) for Dizal’s ZEGFROVY® (sunvozertinib) and in tumor profiling. 

This approval brings rapid next-generation sequencing (NGS) to decentralized clinical settings closer to where patients receive care. With the ability to deliver essential genomic insights in as little as 24 hours*, this approval helps advance the accessibility of precision oncology tools and enables more timely decision making.

A patient’s tumor profile has the potential to guide precision oncology care. However, delays in obtaining results can hinder clinicians’ ability to make informed decisions, potentially causing patients to miss out on targeted therapies, which can impact treatment efficacy and patient outcomes. 

Furthermore, a significant number of patients miss out on targeted therapies due to inefficiencies or lack of access to testing, highlighting the critical role of timely genomic profiling. The Oncomine Dx Express Test was designed to simplify the NGS workflow and connect patients everywhere to precision oncology.

Now with the Oncomine Dx Express Test on the Ion Torrent Genexus Dx Integrated Sequencer, laboratories across a variety of clinical settings can deliver rapid genomic profiling with exceptional accuracy and ease, helping to ensure patients can benefit from the latest advancements in precision oncology.

The Oncomine Dx Express Test is intended for use as a companion diagnostic for ZEGFROVY (sunvozertinib), a targeted therapy from Dizal, to identify patients with non-small cell lung cancer (NSCLC) harboring EGFR exon 20 insertion mutations. In addition, the test has been approved for tumor profiling in solid tumors and detects cancer mutations with evidence of clinical significance and potential clinical significance across 46 genes.

Accelerating informed precision oncology care

The Genexus Dx Integrated Sequencer automates the NGS workflow—from sample preparation to data analysis and reporting—making the technology accessible to more laboratories, including those that are smaller and without previous NGS expertise. It also enables laboratories to generate timely CDx results as well as tumor profiling reports in as little as 24 hours, helping accelerate insights and access to precision oncology.

“NGS has been instrumental in advancing precision oncology, but these insights often aren’t available early enough to inform real-world care,” said Kathy Davy, president of Clinical Next-Generation Sequencing at Thermo Fisher Scientific. “With our rapid NGS solutions, we aim to deliver timely results to clinicians and their patients prior to the initiation of treatment. We’ve been leading companion diagnostics in collaboration with our pharma partners for a decade, and this approval signifies the next step in our journey bringing rapid, decentralized NGS CDx to drug development. We are proud of our collaboration with Dizal to bring ZEGFROVY to the US market.”

Biodesix, one of Thermo Fisher’s collaborators in the validation of Oncomine Dx Express Test on the Genexus Dx Integrated Sequencer, will be the first lab to launch testing services.

“The Biodesix team is excited at the prospect of using the newly FDA approved Genexus Dx Integrated Sequencer for clinical testing using the Oncomine Dx Express test and for supporting our biopharma client projects,” said Gary Pestano, PhD, chief development officer at Biodesix. "Automation of the systems for nucleic acid purification, library preparation, sequencing and report generation has the potential to significantly improve our NGS laboratory workflows by reducing hands-on time and by delivering rapid turnaround times - from sample receipt to results.”

*Timing varies by number of samples and type of run.
