Adaptive Biotechnologies Receives New York State CLEP Approval for clonoSEQ to Detect
and Monitor Minimal Residual Disease (MRD) in Patients with Certain Blood Cancers
SEATTLE, July 31, 2019 Adaptive Biotechnologies Corporation (Nasdaq:ADPT) ( Adaptive ), a commercial-stage
biotechnology company that reads and translates the genetic code of the adaptive immune system with the goal of developing personalized diagnostics and therapeutics to improve patient lives, today announced that the State of New York Clinical
Laboratory Evaluation Program (CLEP) has approved the clonoSEQ Assay for the detection and monitoring of minimal residual disease (MRD) in patients with
B-cell blood cancers. In addition to CLEP approval, clonoSEQ is also the first test to be authorized by the U.S. Food and Drug Administration (FDA) for MRD assessment in bone marrow samples from patients with B-cell acute lymphoblastic leukemia (ALL) and multiple myeloma.
The CLEP approval makes clonoSEQ testing accessible to
patients in New York who have been diagnosed with B-cell cancers, a subset of lymphoid cancers that includes ALL, multiple myeloma, chronic lymphocytic leukemia (CLL) and
B-cell non-Hodgkin s lymphoma (NHL). Testing under CLEP may be performed using DNA from bone marrow, blood and archived tissue samples. With this approval, clonoSEQ
MRD testing is now available in all 50 states and has a considerable and growing payor footprint (>140MM covered lives to date).
CLEP approval for clonoSEQ means patients in New York can now work with their cancer care team to incorporate clonoSEQ into their treatment regimen to accurately and reliably assess and monitor their disease over time, using multiple sample types,
including blood samples, said, Chad Robins, CEO and co-founder, Adaptive Biotechnologies. This rigorous approval also supports our ongoing work to expand access to patients and our pursuit of FDA
authorization for new indications for clonoSEQ in other lymphoid cancers and sample types.
clonoSEQ has been ordered by clinicians in nearly 300
healthcare systems and institutions, including 27 of the 28 NCCN centers in the United States, and used by more than 30 biopharmaceutical companies in over 120 clinical trials.
The approval gives patients in New York access to the standardized, FDA-cleared clinical MRD testing that is
already being utilized throughout the rest of the country, said Dr. Ajai Chari, Associate Professor of Medicine, Hematology and Medical Oncology at The Tisch Cancer Institute at Mount Sinai, who was a past consultant for the clonoSEQ
About the clonoSEQ Assay
assay was granted de novo designation and marketing authorization by FDA for the detection and monitoring of minimal residual disease (MRD) in patients with multiple myeloma (MM) and B-cell acute
lymphoblastic leukemia (ALL) using DNA from bone marrow samples. clonoSEQ is the first and only FDA-authorized in vitro diagnostic assay for MRD testing. It is also the first clinical diagnostic powered
by immunosequencing to receive FDA clearance. clonoSEQ leverages Adaptive s proprietary immunosequencing 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 detect 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 are strongly associated with MRD levels measured by the clonoSEQ Assay in patients diagnosed with ALL and MM. clonoSEQ testing is covered by Medicare and an expanding list of private payors in alignment with the FDA label.
clonoSEQ 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. For important information about the FDA-cleared uses of clonoSEQ, including the full intended use, limitations, and detailed performance characteristics, please visit
About Adaptive Biotechnologies
Adaptive Biotechnologies is a commercial-stage biotech 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 to develop products in life sciences research, clinical diagnostics, and drug discovery.
We have two commercial products, and a robust clinical pipeline to diagnose, monitor and enable the treatment of diseases such as cancer, autoimmune conditions and infectious diseases. Our goal is to develop and commercialize immune-driven clinical
products tailored to each individual patient. For more information, please visit: adaptivebiotech.com.
