Adaptive Biotechnologies and Collaborators to Present Eighteen Studies at the American Society of Hematology Annual Meeting 2016

Adaptive Biotechnologies, the leader in combining next-generation sequencing (NGS) and expert bioinformatics to profile T- and B-cell receptors of the adaptive immune system, and its collaborators from pharmaceutical companies and academic centers around the world, will share data further demonstrating the clinical validity and prognostic value of the clonoSEQ Assay for MRD assessment in lymphoid cancers. Data including MRD assessment and T-cell repertoire characterization will be presented in eight oral and ten poster presentations, including five different lymphoid cancer subtypes, at the American Society of Hematology (ASH) Annual Meeting, December 3-6, 2016 in San Diego, CA.

“Providing a diagnostic assay that is ultra-sensitive and standardized to determine treatment response and predict outcomes in people with lymphoid cancers is a priority for Adaptive and furthers our mission to improve patient care,” said Harlan Robins, Chief Scientific Officer and Co-Founder, Adaptive Biotechnologies. “Data presented during ASH demonstrate the breadth of our technology’s capability to predict which patients are at greatest risk of relapse and serve as a reliable surrogate endpoint in pivotal clinical trials.”

Representatives from Adaptive Biotechnologies will be exhibiting at ASH booth #2843 to answer questions about its immunosequencing technology including the clonoSEQ Assay and the immunoSEQ^® Assay for research use only.

About Minimal/Measurable Residual Disease


Minimal/measurable residual disease (MRD) refers to cancer cells that remain in the body of a person with lymphoid cancer after treatment. These cells can be present at levels undetectable by traditional morphologic, microscopic examination of blood, bone marrow or a lymph node biopsy. Sensitive molecular technologies, such as next-generation sequencing utilized by the Adaptive Biotechnologies clonoSEQ Assay, are needed for reliable detection of MRD at levels below the limits of traditional assessment.

About the clonoSEQ^® Assay

The Adaptive Biotechnologies clonoSEQ Assay enables physicians to utilize next-generation sequencing-based MRD detection to inform clinical decision making for patients with lymphoid malignancies. The clonoSEQ assay detects, and quantifies DNA sequences found in malignant cells, which can be tracked throughout treatment. This robust assay provides consistent, accurate measurement of disease burden which allows physicians to visualize response to treatment over time to optimize patient management. Adaptive will be seeking marketing authorization from FDA for the clonoSEQ Assay.
