Adaptive Biotechnologies Announces Launch of clonoSEQ® to Assess Minimal Residual Disease (MRD) in Patients with Diffuse Large B-Cell Lymphoma (DLBCL) Using Circulating Tumor DNA (ctDNA)
SEATTLE, Dec. 01, 2022 (GLOBE NEWSWIRE) -- Adaptive Biotechnologies Corporation (Nasdaq: ADPT), a commercial stage biotechnology company that aims to translate the genetics of the adaptive immune system into clinical products to diagnose and treat disease, today announced the launch of its clonoSEQ® Assay to detect minimal residual disease (MRD) in blood for patients with diffuse large B-cell lymphoma (DLBCL). DLBCL is the most common type of non-Hodgkin lymphoma (NHL), affecting more than 100,000 people in the U.S. Because DLBCL is an aggressive but also potentially curable disease for many patients, disease monitoring plays a central role in patient management.
clonoSEQ can assess a patient’s MRD status in DLBCL by measuring ctDNA, the fragments of DNA released into the blood from dying cancer cells which can serve as a measure of tumor burden. clonoSEQ is available in DLBCL as a CLIA-validated laboratory developed test (LDT), and beginning this week the company will accept DLBCL blood samples in Streck® tubes, enabling broader access to ctDNA-based MRD testing for clinicians and patients.
“We are excited to continue to expand access to clonoSEQ as a highly specific and less invasive tool for DLBCL monitoring which will complement the current standard imaging methods,” said Nitin Sood, chief commercial officer, MRD, Adaptive Biotechnologies. “By measuring ctDNA in blood, clonoSEQ provides clinicians with a sensitive and quantitative assessment of disease burden so that they can detect relapse sooner and are better equipped to create a more precise treatment plan for each patient.”
clonoSEQ MRD testing is covered by Medicare in DLBCL, with coverage extending to all DLBCL patients regardless of line of therapy, treatment regimen, or testing timepoint. clonoSEQ is the first and only MRD test to receive Medicare coverage in DLBCL.
Robust peer-reviewed evidence supports the use of clonoSEQ as a powerful blood-based prognostic tool in DLBCL. Data published in the post-frontline surveillance setting, the transplant setting, and post-CART demonstrate the utility of clonoSEQ ctDNA assessment to accurately predict which patients are likely to relapse. When used in conjunction with or as a supplement to imaging-based methods established in clinical practice guidelines, clonoSEQ has the potential to help oncologists optimize DLBCL patient care.
“The continued development of new treatments for DLBCL requires novel, precise ways to monitor disease progression. Imaging is an important monitoring tool but also has known clinical limitations and drawbacks for patients,” said Dr. Tara Graff, hematologist/oncologist at Mission Cancer and Blood. “clonoSEQ testing in blood can serve as a complement to imaging, aiding in my work-up and decision-making process for DLBCL patients and in some cases, helping spare patients from unnecessary procedures and treatments.”
In addition to its availability as a CLIA-validated LDT in DLBCL in blood, clonoSEQ is also available as an FDA-cleared in vitro diagnostic (IVD) test service provided by Adaptive Biotechnologies to detect 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).
About the clonoSEQ Assay
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.
