Invivoscribe^® Technologies Inc., a global company with decades of experience providing clonality and biomarker test solutions for the fields of oncology and personalized molecular medicine^®, announces the release of the Research Use Only (RUO) version of its LymphoTrack^® TRB Assay for the Illumina MiSeq^® platform. Included with the assay is specialized bioinformatics software that allows researchers and pharmaceutical companies conducting clinical trials, to identify and track clonal populations by performing minimal residual disease (MRD) testing of subsequent samples.

Tests that detect TRB clonal rearrangements are useful in the study of T-cell malignancies as leukemias and lymphomas generally share one or more cell-specific or “clonal” antigen receptor gene rearrangement(s). The LymphoTrack TRB Assay on MiSeq^® identifies clonal TRB (VDJ) rearrangements, the associated VDJ region DNA sequences, and provides the frequency distribution of V, D, and J, region segment utilization using the included LymphoTrack bioinformatics software. This assay will increase the probability of identifying T cell receptor beta chain gene rearrangements versus when testing for TRG gene rearrangements only.

The LymphoTrack TRB Assay completes the comprehensive menu of Invivoscribe LymphoTrack Clonality Assays which enable rapid clonal rearrangement identification with the unparalleled accuracy and sensitivity of next generation sequencing (NGS). The LymphoTrack product line allows customers to simultaneously run any combination of assays, thus significantly reducing both cost and time to results. The kit includes LymphoTrack MiSeq^® software which automates the sorting and individual tracking of each sample and IGH, IGK, TRG and TRB target, interprets sequence data, and generates succinct, yet comprehensive reports for each sample and each target. The LymphoTrack MRD software enables temporal tracking of clonal populations, and has demonstrated potential to improve subject monitoring in clinical trial and research settings. Both the LymphoTrack MiSeq^® and MRD software programs facilitate international standardization and objective interpretation for clonality and MRD testing. Invivoscribe will also seek CE IVD marking of a LymphoTrack TRB Assay for sale of kits to laboratories outside North America, and 510(k) clearance in the United States. We have already started this process for our menu of LymphoTrack Clonality Assays.
