Official ADAPTIVE BIOTECHNOLOGIES CORPORATION press release Adaptive Biotechnologies and Collaborators to Present More than 30 Abstracts Demonstrating the Actionability of clonoSEQ® MRD Testing in Blood Cancer Patient Care and Drug Development at the 65th ASH Annual Meeting December 05, 2023 at 07:31 am EST Share SEATTLE, Dec. 05, 2023 (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, together with its collaborators will present data from more than 30 abstracts demonstrating the actionability of Adaptive’s next-generation sequencing (NGS)-based clonoSEQ® test in assessing minimal residual disease (MRD) in blood cancer patients at the 65th Annual Meeting of the American Society of Hematology (ASH), December 9-12 in San Diego, California. clonoSEQ is the only U.S. Food and Drug Administration (FDA)-cleared test 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). clonoSEQ testing for other lymphoid malignancies, including diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and follicular lymphoma (FL) is currently available for clinical use as a laboratory-developed test (LDT) performed at Adaptive's CLIA-certified lab in Seattle, Washington. “Data continue to mount which reinforce the prognostic value of MRD and highlight its growing role in the blood cancer treatment landscape,” said Susan Bobulsky, Senior Vice President, Diagnostics, Adaptive Biotechnologies. “clonoSEQ provides actionable insights which are guiding the personalization of care for blood cancer patients today, as well as shaping the future of blood cancer treatment by supporting the development of cutting-edge therapeutics.” Minimal residual disease – also referred to as measurable residual disease – is one of the strongest predictors of outcomes in blood cancers and routine testing provides a personalized way to track a patient’s individual response to treatment and inform shared decision-making to optimize care. In addition to clinical use, MRD testing is widely used in drug development to get an early read on efficacy to inform patient stratification and increasingly as a trial endpoint. Data supporting clonoSEQ’s clinical and research utility, as well as insights based on analysis of real-world experience, will be featured in a late-breaking presentation, eight oral presentations and 24 posters across lymphoid malignancies. Studies will be presented demonstrating the clinical actionability of MRD testing across disease states. Notably, data illustrating the prognostic value of clonoSEQ MRD assessment using peripheral blood in MM and from circulating tumor DNA (ctDNA) in DLBCL will also be presented. Additionally, biopharmaceutical companies and other investigators will share data from 13 studies using clonoSEQ as an endpoint to measure deep responses during or after therapy, including novel treatment regimens such as CAR T-cell therapies and bispecifics. To advance biopharmaceutical partner research, Adaptive recently made available a new version of the ctDNA-based assay to assess MRD in DLBCL clinical trials. The research use only (RUO) assay has increased sensitivity to enable MRD assessment in clinical trials at the end of treatment timepoint (EOT) when disease burden is lowest as well as in post-treatment surveillance and later lines of therapy.

Update for the "Watch" Registry, a Real-World Observational Study Using clonoSEQ® to Monitor MRD in Lymphoid Malignancies Sunday, December 10, 2023, 6:00 PM-8:00 PM 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.
