Invivoscribe – NPM1 MRD Assay now available globally

Invivoscribe’s NPM1 MRD Assay is an NGS-based, targeted, deep-sequencing assay that detects and monitors DNA sequences specific to identified mutations from the primary sample identified at diagnosis with an allelic sensitivity level of 5×10-5. This assay identifies and reports mutation variants ‘A,’ ‘B’, ‘D’, and ‘Other’ in subjects with no overt evidence of disease.  

In addition, the NPM1 MRD Assay can be multiplexed with the FLT3 ITD MRD Assay to improve throughput and reduce cost.

FLT3 ITD MRD Assay & NPM1 MRD Assay

Background

Measurable residual disease (MRD) is a critical biomarker in acute myeloid leukemia (AML) research and discovery. While each genetic profile of AML differs, the combination of genetic aberrations, such as the presence of FLT3-ITD and NPM1 insertions, can provide information over the course of this disease. In a study evaluating the persistence of residual FLT3-ITD and NPM1 mutations among subjects with AML in first remission prior to allogeneic cell transplant, those with an allele fraction ≥0.01% trended towards elevated risk of relapse and mortality compared to those without these mutations. 1,2
NPM1 MRD Assay Workflow - 2025

Principle of the Procedure

Invivoscribe’s targeted, deep-sequencing assays are easily implemented together, following identical, streamlined workflows. Designed for high-throughput laboratories, each kit configuration includes 24 master mixes, each containing a carefully-selected, unique dual-index to prevent cross-contamination due to barcode hopping. FLT3 ITD MRD Software and NPM1 MRD Software analysis is initiated through REST-API or command line interface. The data is output in a tab-separated value (TSV) file.
