Adaptive Biotechnologies and Collaborators to Present 28 Studies at ASH 2018 that Support the Use of the clonoSEQ® Assay to Detect and Monitor Minimal Residual Disease in Patients with Blood Cancers

November 30, 2018

SEATTLE--(BUSINESS WIRE)--Nov 30, 2018--Adaptive Biotechnologies and its collaborators will present 28 studies, including a late-breaker presentation, at the 60 th American Society of Hematology (ASH) Annual Meeting & Exposition in San Diego, December 1-4, 2018. The data presented at ASH builds on the recent FDA clearance of the clonoSEQ ® Assay to detect and monitor minimal residual disease (MRD) in patients with multiple myeloma or B-cell acute lymphoblastic leukemia (ALL), using DNA from a patient’s bone marrow sample.

Among the 28 clonoSEQ studies at ASH, new research supports expanded use in myeloma and ALL, efficacy in other blood cancers like chronic lymphocytic leukemia (CLL) and Non-Hodgkin’s Lymphoma (NHL), and ability to detect MRD in blood-based samples. New data generated using clonoSEQ will be presented that demonstrate the value of a highly sensitive, standardized next-generation sequencing MRD test to determine early response to treatment and predict potential relapse in myeloma and ALL patients. Data will also be presented that look at the sensitivity of clonoSEQ and other technologies to assess MRD.

“This year has been a landmark year for minimal residual disease. It’s one of the first new endpoints we’ve seen in hematology clinical trials since progression-free survival,” said Chad Robins, chief executive officer and co-founder of Adaptive Biotechnologies. “The volume and the quality of MRD data being presented at ASH establish that MRD has firmly taken root as a clinical trial endpoint and biomarker that can help predict patient outcomes. With greater reliance on MRD in clinical trials, as well as a growing focus on monitoring MRD to inform patient care, having access to a highly sensitive, standardized test like clonoSEQ is paramount.”

clonoSEQ, the first clinical application of Adaptive’s pioneering immune profiling platform, will be featured in a late-breaker presentation, 12 oral presentations and 15 posters. Data on approved, investigational and research uses will be presented across a range of cancers – 14 multiple myeloma, 4 ALL, 4 CLL, 4 mantle cell lymphoma, 1 diffuse large B-cell lymphoma, and 1 Hodgkin’s lymphoma.

About Minimal Residual Disease

Minimal residual disease (MRD), also referred to as measurable residual disease, refers to cancer cells that remain in the body after treatment for patients with lymphoid cancers. These cells can be present at levels undetectable by traditional morphologic methods, microscopic examination of blood, or a bone marrow or a lymph node biopsy.

MRD is used by physicians to detect and monitor disease burden in patients and to inform their treatment decisions. Clinical practice guidelines recommend assessing MRD at multiple time points during treatment and maintenance in MM and ALL, and guidelines for both diseases include NGS as a recommended testing method. The prognostic value of MRD assessment has been demonstrated in multiple lymphoid cancers. Controlled trials have shown that even small amounts of disease are profoundly significant for predicting a patient’s long-term clinical outcomes. Therefore, highly sensitive, standardized molecular technologies are needed for reliable detection of MRD.

Measurement of MRD is currently being evaluated as a way to measure efficacy in drug trials, with the potential to expedite the approval of emerging therapies.

About the clonoSEQ ®   Assay

The Adaptive Biotechnologies clonoSEQ Assay has been granted De Novo designation by the FDA as an in vitro diagnostic (IVD) to detect and monitor minimal residual disease (MRD) in patients with multiple myeloma (MM) and B-cell acute lymphoblastic leukemia (ALL) using DNA from bone marrow samples. It identifies and quantifies specific DNA sequences found in malignant cells, allowing clinicians to monitor patients for changes in disease burden during and after treatment. This robust assay provides sensitive and accurate measurement of residual disease that allows physicians to predict patient outcomes, assess response to therapy over time, monitor patients during remission and detect potential relapse. The clonoSEQ Assay is a single-site assay performed at Adaptive Biotechnologies. It is also available as a CLIA-regulated laboratory developed test (LDT) service for use in other lymphoid cancers.

clonoSEQ was reviewed under the FDA’s De Novo premarket review pathway, a regulatory pathway for some low- to moderate-risk novel devices for which there is no legally marketed predicate device.
