Sysmex Inostics Launches New Ultra-Sensitive Leukemia Blood Test for Early Detection of Cancer Cells Following Initial Therapy

Sysmex Inostics (Baltimore, MD, USA) has developed a new CLIA-validated liquid biopsy test for the detection of Minimal Residual Disease (MRD) in Acute Myeloid Leukemia (AML) to better help in the fight against cancer.

The new test, AML-MRD-SEQ, uses a targeted Next Generation Sequencing (NGS) panel and adds to the portfolio of ultra-sensitive Plasma-Safe-SeqS technology NGS tests available through Sysmex Inostics' CLIA lab services. Previous generations of AML MRD tests were only able to detect a limited number of mutations that have an established therapeutic indication. AML-MRD-SEQ offers a more expansive panel covering 68 regions across 20 genes, including established MRD markers such as NPM1, and demonstrating significant potential for use as an investigational tool for other markers with prognostic values that are not yet well-established. The new highly sensitive AML-MRD-SEQ test with broader genomic coverage offers the opportunity for early intervention and clinical trial enrollment.

AML-MRD-SEQ offers reliable detection of molecular MRD with 50 to 100 times greater sensitivity versus other currently available NGS pan-heme tests. Such ultra-sensitive detection of low-level mutant molecules allows clinical trial sponsors to execute on clinical development timelines more efficiently. AML is one of the deadliest blood cancers and relapses usually result in a poor prognosis, making it necessary to test patients for MRD after initial treatment as a prognostic indicator of therapeutic effectiveness and relapse risk. Applying Sysmex Inostics' ultra-sensitive liquid biopsy NGS technology, Plasma-Safe-SeqS, to the detection of gene mutations associated with AML MRD enables accelerated clinical development timelines, cost savings, and improved outcomes throughout the clinical trial process.

"The new test, AML-MRD-SEQ, offers clinical trial sponsors, and eventually physicians and patients, an early signal for the presence of cancer cells following initial therapy. This new liquid biopsy solution is a major step in developing treatment strategies to support the fight against a devastating disease," said Shinichi Sato, CEO of Sysmex Inostics, Inc.
