Invivoscribe Expands Business into Solid Tumors with Assays and Services to Identify and Monitor CAR-T and TCR Immuno-Therapies

Reading time: 2 – 4 minutes

Invivoscribe® Technologies Inc., a global company with decades of experience providing internationally standardized clonality and biomarker testing solutions for the fields of oncology, personalized molecular diagnostics®, and personalized molecular medicine®, reports that its next-generation sequencing (NGS) LymphoTrack® Assay kits are being used by its LabPMM® clinical laboratories, pharmaceutical partners, and cancer centers to identify and monitor chimeric antigen receptor T-cells (CAR-T) and engineered T-cell receptors in peripheral blood of subjects in support of immuno-therapeutic drug development and treatment regimen development for both hematologic and solid tumors.

Immunotherapy is one of the most exciting new areas of precision medicine. The rapidly evolving field is centered on utilizing a patient’s own immune system to surveil, target, and eliminate cancer cells. A number of immuno-therapeutic methods have demonstrated promising clinical value. In order to demonstrate clinical efficacy and move these novel therapies quickly through the regulatory agencies, accurate and standardized tests need to be employed to measure and monitor these bioengineered constructs. Leading stakeholders have turned to using Invivoscribe’s internationally standardized assays to fulfill this need.

A number of Invivoscribe LymphoTrack Assays, formatted for use on both the Illumina MiSeq® and Thermo Fisher Ion PGM™platforms, were designed to detect somatic gene rearrangements within the antigen receptor loci. These assays also recognize conserved elements within the bioengineered immuno-therapeutic constructs of CAR-T and TCRs, making them robust candidates for dual use purposes: (1) identifying and monitoring immuno-therapeutic constructs in the peripheral blood and (2) identifying and monitoring clonotypes associated with malignant B- and T-cell populations. Both capabilities can be achieved simultaneously using the same reagents, bioinformatics software, and workflow.

Once identified, these constructs and malignant clones can be tracked to levels of 1 cell in a million (10-6) sensitivity. Testing can be done either at LabPMM laboratories or entirely in an investigator’s own facility, with the bioinformatics analysis done on customer’s own computers, ensuring rapid turn around times as well as data protection.

“Our internationally standardized, NGS-based LymphoTrack clonality assays with bioinformatics software provide a comprehensive solution in support of laboratories and pharmaceutical companies developing new drugs and immuno-therapies. Having access to these powerful tools will accelerate getting new drugs and immuno-therapies to patients. As importantly, results from standardized assays generate more reproducible and reliable results, leading to better, more accurate treatments. These improved treatments will be a game changer and a huge benefit to patients and to the fields of personalized molecular diagnostics and precision medicine,” said Dr. Jeffrey Miller, Founder, CSO & CEO of Invivoscribe. “A number of our assays and associated bioinformatics software are currently being used by leading cancer centers and pharmaceutical partners in support of optimizing treatments for patients, and to stratify, enroll, and track MRD in patients in international phase II and phase III clinical studies. Our vision is to improve patient care by making these products accessible to all of our partners and customers.”
