SEATTLE, Dec. 05, 2022 (GLOBE NEWSWIRE) — Adaptive Biotechnologies Corporation (Nasdaq: ADPT), together with its collaborators, will present data from more than 30 abstracts showcasing the benefit of Adaptive’s next-generation sequencing (NGS)-based clonoSEQ

^®

Assay in measuring minimal residual disease (MRD) in blood cancer patients at the 64

^th

Annual Meeting of the American Society of Hematology (ASH) taking place December 10-13, 2022.

clonoSEQ is the only U.S. Food and Drug Administration (FDA)-cleared assay for MRD assessment in multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and B-cell acute lymphoblastic leukemia (B-ALL). Adaptive recently announced the launch of clonoSEQ to assess MRD in the blood of patients with diffuse large B-cell lymphoma (DLBCL) using ctDNA. The assay is widely available to clinicians and patients across the U.S.

“The data presented at ASH continues to reinforce the value of serial MRD testing with clonoSEQ as a sensitive prognostic tool in real-world settings and in clinical trials,” said Nitin Sood, chief commercial officer, MRD, Adaptive Biotechnologies. “Data continues to demonstrate that testing MRD at multiple timepoints throughout a patient’s cancer journey is part of the new standard of care for most lymphoid malignancies and is critical to a physician’s ability to assess prognosis, determine response to treatment, detect relapse, and ultimately optimize care.”

MRD testing allows for direct measurement of the number of cancer cells remaining in the body during and after treatment. Leveraging Adaptive’s immune medicine platform, clonoSEQ can detect one cancer cell among a million healthy cells. Assessment with clonoSEQ provides a standardized, accurate, and sensitive measurement of MRD.

Data generated using clonoSEQ across various blood cancers will be featured in the selected 12 oral presentations and 21 posters listed below at ASH. Five of the presentations are studies using real-world evidence to demonstrate how serial clonoSEQ testing is being utilized in the clinic to inform physician decisions across indications and therapeutic regimens to guide personalized treatment plans, including discontinuation of therapy. Other presentations will highlight the value of utilizing clonoSEQ in clinical trials to assess and predict the effectiveness of investigational, novel therapeutics.

About the clonoSEQ Assay


The clonoSEQ Assay is the first and only FDA-cleared in vitro diagnostic (IVD) test service to detect minimal residual disease (MRD) in bone marrow from patients with multiple myeloma (MM) or B-cell acute lymphoblastic leukemia (B-ALL) and blood or bone marrow from patients with chronic lymphocytic leukemia (CLL). clonoSEQ testing for diffuse large B-cell lymphoma (DLBCL) patients is currently available for clinical use as a laboratory-developed test (LDT) performed at Adaptive’s CLIA-certified lab in Seattle, WA. clonoSEQ ctDNA-based MRD testing in DLBCL has also been approved by New York State’s Clinical Laboratory Evaluation Program (CLEP). Medicare covers clonoSEQ in these four indications and is aligned with clinical practice guidelines which support assessing MRD at multiple time points throughout therapy to monitor treatment response and help predict patient outcomes.

The clonoSEQ Assay leverages Adaptive Biotechnologies’ proprietary immune medicine platform to identify and quantify specific DNA sequences found in malignant cells, allowing clinicians to assess and monitor MRD during and after treatment. The assay provides standardized, accurate, and sensitive measurement of MRD that allows physicians to predict patient outcomes, assess response to therapy over time, monitor patients during remission, and predict potential relapse. Clinical practice guidelines in hematological malignancies recognize that MRD status is a reliable indicator of clinical outcomes and response to therapy, and clinical outcomes have been shown to be strongly associated with MRD levels measured by the clonoSEQ Assay in patients diagnosed with CLL, MM, ALL and DLBCL.

About Adaptive Biotechnologies


Adaptive Biotechnologies (“we” or “our”) is a commercial-stage biotechnology company focused on harnessing the inherent biology of the adaptive immune system to transform the diagnosis and treatment of disease. We believe the adaptive immune system is nature’s most finely tuned diagnostic and therapeutic for most diseases, but the inability to decode it has prevented the medical community from fully leveraging its capabilities. Our proprietary immune medicine platform reveals and translates the massive genetics of the adaptive immune system with scale, precision and speed. We apply our platform to partner with biopharmaceutical companies, inform drug development, and develop clinical diagnostics across our two business areas: Minimal Residual Disease (MRD) and Immune Medicine. Our commercial products and clinical pipeline enable the diagnosis, monitoring, and treatment of diseases such as cancer, autoimmune disorders, and infectious diseases. Our goal is to develop and commercialize immune-driven clinical products tailored to each individual patient.
