Adaptive Biotechnologies Announces New Translational Collaboration to Measure Minimal Residual Disease With clonoSEQ Assay Across BeiGene’s Lymphoid Malignancy Pipeline

Adaptive Biotechnologies Corporation recently announced a multi-year, global translational collaboration with BeiGene to assess minimal residual disease (MRD) using clonoSEQ assay technology across the company’s pipeline of treatments for patients with lymphoid malignancies.

“Adaptive is pleased to partner with BeiGene to support the clinical development and potential regulatory approval of their investigational therapies in lymphoid malignancies,” said Mary Pat Lancelotta, Senior Vice President, BioPharma at Adaptive Biotechnologies. “MRD status has strong prognostic value, and by integrating the measure into clinical studies our partners can more quickly and efficiently evaluate and advance novel therapeutics.”

MRD assessment is playing a growing role in clinical trials for lymphoid malignancies by providing an early measure of treatment response and serving as a potential endpoint, which may enable novel therapies to be made available to patients sooner. As the first and only standardized test authorized by the US FDA for MRD assessment in bone marrow from patients with multiple myeloma or B-cell acute lymphoblastic leukemia (B-ALL) and blood or bone marrow from patients with chronic lymphocytic leukemia (CLL), Adaptive’s clonoSEQ assay technology is the test of choice among drug developers. It has been included in global, label-enabling studies for a multitude of therapies approved over the past several years and is also now widely adopted in the clinic. It is used at all 33 National Comprehensive Cancer Network (NCCN) centers, and as data supporting its clinical utility mount, its use is also growing in the community setting.

This multi-year agreement will cover existing and future programs and adds to Adaptive’s growing list of translational collaborations with biopharmaceutical companies. As part of the collaboration, MRD status based on Adaptive’s clonoSEQ assay may be used as an endpoint in certain clinical trials to assess the depth and duration of response to BeiGene’s investigational medicines in patients with lymphoid malignancies. Adaptive will receive an upfront payment and will be eligible to receive future milestone payments upon achievement of specific regulatory milestones in certain geographies. Specific financial terms of the agreement will not be disclosed.

The clonoSEQ assay 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. Medicare covers clonoSEQ in these four indications and is aligned with clinical practice guidelines which support assessing MRD at multiple time points throughout therapy to monitor treatment response and help predict patient outcomes.

The clonoSEQ assay 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 therapy over time, monitor patients during remission, and predict potential relapse. 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 the clonoSEQ assay in patients diagnosed with CLL, MM, ALL and DLBCL.

Adaptive Biotechnologies 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.
