Adaptive Biotechnologies Highlights New Data at 2025 ASCO Annual Meeting and EHA 2025 Congress Demonstrating How clonoSEQ® MRD Assessment is Optimizing Patient Care and Drug Development in Lymphoid Cancers
30 scientific abstracts will be presented using clonoSEQ for MRD assessment across multiple types of blood cancers
SEATTLE, May 30, 2025 (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 that its next-generation sequencing (NGS)-based clonoSEQ® test for measurable residual disease (MRD) assessment will be included in 30 presentations, including a total of 14 oral presentations, across the American Society of Clinical Oncology (ASCO) Annual Meeting taking place May 30-June 3 in Chicago and the European Hematology Association (EHA) Congress taking place June 12-15 in Milan. These presentations include notable new data supporting the clinical actionability of clonoSEQ in both multiple myeloma (MM) and chronic lymphocytic leukemia (CLL).
"The breadth of new MRD evidence being shared across various blood cancer types at ASCO and EHA this year highlights the transformative impact MRD is having on clinical care and drug development," said Susan Bobulsky, Chief Commercial Officer, MRD, Adaptive Biotechnologies. "These data presentations are a testament to the central role that clonoSEQ MRD testing now plays in clinical management and drug development across lymphoid cancers, particularly when combined with several clonoSEQ data presentations in diffuse large B-cell lymphoma (DLBCL) anticipated at the 18th International Conference on Malignant Lymphoma (iCML) on June 17-21, 2025 in Lugano, Switzerland."

About clonoSEQ clonoSEQ® is the first and only FDA-cleared in vitro diagnostic (IVD) test for detecting and tracking minimal (or measurable) residual disease (MRD) in patients with multiple myeloma (MM) or B-cell acute lymphoblastic leukemia (B-ALL) using bone marrow, and in patients with chronic lymphocytic leukemia (CLL) using blood or bone marrow. clonoSEQ is also available in diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and other lymphoid cancers and specimen types as a CLIA-validated laboratory developed test (LDT). clonoSEQ is covered by Medicare for MM, CLL, ALL, DLBCL and MCL.
clonoSEQ identifies and quantifies DNA sequences in malignant cells—detecting one cancer cell in one million healthy cells—to help clinicians and researchers assess and monitor MRD with precision over time. It delivers standardized, sensitive results that inform treatment decisions, predict outcomes, and detect relapses earlier.
clonoSEQ is CE-marked under the EU In Vitro Diagnostic Regulation (IVDR). For intended use details in the EU, see the instructions for use, available on request.

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.
