Adaptive Biotechnologies Announces Data Supporting the Clinical Benefits of MRD Assessment with clonoSEQ® To Be Presented at the Upcoming 2024 ASCO Annual Meeting and EHA2024 Hybrid Congress

SEATTLE, May 31, 2024 (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, announced that its next-generation sequencing (NGS)-based clonoSEQ® test for measurable residual disease (MRD) assessment will be included in several oral and poster presentations at the American Society of Clinical Oncology (ASCO) Annual Meeting taking place May 31-June 4 in Chicago and at the European Hematology Association (EHA) Hybrid Congress taking place June 13-16 in Madrid and virtually.

“The data that will be presented at ASCO and EHA this year build on the expansive evidence base supporting the clinical significance and actionability of MRD testing with clonoSEQ within the quickly evolving blood cancer treatment landscape,” said Susan Bobulsky, chief commercial officer, MRD, Adaptive Biotechnologies. “clonoSEQ continues to be the gold standard in MRD assessment, empowering clinicians with the most reliable insights to navigate complex treatment decisions and arming drug developers with a highly sensitive and standardized assay to confidently advance the most promising therapeutics.”

MRD status is a powerful predictor of outcomes in blood cancers. Routine MRD testing offers a personalized approach to monitor and evaluate an individual’s response to treatment, identify early signs of relapse before symptoms occur, and inform shared decision-making to optimize care. Beyond clinical applications, clonoSEQ assay technology is used extensively in drug development as a robustly validated tool to understand treatment efficacy and determine depth and kinetics of response. It is also increasingly being used as a primary endpoint in clinical trials.

The clinical trial data and real-world evidence to be presented at ASCO and EHA further underscore the clinical benefit of specific and sensitive MRD assessment with clonoSEQ. Highlights include:

About clonoSEQ

clonoSEQ 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 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 treatment, inform changes in therapy, monitor disease burden over time, and detect potential relapse early. 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 clonoSEQ 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.
