Advanced MRD detection using NGS and blinatumomab made deeper molecular remission in B-ALL patients achievable. Further large-scale studies are warranted to verify the prognostic value of NGS in detecting lower levels of MRD in ALL patients treated in the current immunotherapy era.
"Genetron Holdings Limited...today announced it has received a CE Mark for its proprietary Human B Lymphocyte Minimal Residual Disease Detection Kit (Reversible Termination Sequencing Method), which is also known as Seq-MRD® (Registration Number: DE/CA20/01-IVD-Luxuslebenswelt-190/22)...Based on high-throughput next generation sequencing (NGS) technology, Seq-MRD® assay is intended to test the CDR3 regional sequence of the IgH/K/L gene of the B cell receptor (BCR) in bone marrow samples collected from patients with B lymphpocytic leukemia (B-ALL/CLL) and multiple myeloma (MM) before and after the treatment. By screening out significant and specific clonal rearrangement form in a patient's tumor cells, this approach can detect minimal residual disease and provide a reference for the follow-up treatment of cancer survivors."
