ADPT - 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 | Benzinga

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 65^th 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.
