SEATTLE, WA, March 28, 2019 — Adaptive Biotechnologies and its collaborators will present 11 studies, including an oral presentation and 10 poster presentations, at the American Association of Cancer Research (AACR) Annual Meeting in Atlanta, GA, March 29 – April 3.

New data will demonstrate how immunosequencing at scale and with precision using Adaptive’s immunoSEQ^® Assay may be used in clinical trials to predict overall survival and response to novel immunotherapies, such as checkpoint inhibitors and cancer vaccines, in solid tumors.  Other data will examine the ability of immunoSEQ to quantify and characterize the individual T cell receptors (TCR) of tumor infiltrating lymphocytes (TILs), a type of white blood cell that attacks cancer cells and controls tumor proliferation, to assist in identifying subtypes of colorectal cancer. This information may be used to help determine response to immunotherapy and patient outcomes among subtypes. Collectively the studies also demonstrate a growing use of immunoSEQ by academia and the pharmaceutical industry to help guide clinical research.

“Adaptive’s immune medicine platform is essential to helping our academic and pharmaceutical industry partners decode the information stored in our immune systems to answer translational research questions and discover new prognostic and diagnostic signals in oncology clinical trials,” said Chad Robins CEO and co-founder of Adaptive Biotechnologies. “Making this tool widely available to research partners helps us drive toward our goal of transforming medicine to improve patient lives.”

Abstracts are available on AACR website: https://www.abstractsonline.com/pp8/#!/6812.  immunoSEQ presentations of interest include:

About immunoSEQ Assays

Adaptive’s immunoSEQ Assay helps researchers make discoveries in areas such as oncology, autoimmune disorders, infectious diseases and basic immunology. The immunoSEQ Assay can identify millions of T- and B-cell receptors from a single sample in exquisite detail. Offered as a Service or Kit, the immunoSEQ Assay is used to ask and answer translational research questions and discover new prognostic and diagnostic signals in clinical trials.  immunoSEQ Assay provides quantitative, reproducible sequencing results along with access to powerful, easy-to-use analysis tools. The immunoSEQ Assay is for research use only and is not for use in diagnostic procedures.
