On September 28, 2018, the U.S. Food and Drug Administration announced that the agency is permitting marketing of ClonoSEQ assay, a next generation sequencing (NGS)-based test for minimal residual disease (MRD) in patients with acute lymphoblastic leukemia (ALL) or multiple myeloma. MRD is a measure of the amount of cancer cells remaining in a person’s bone marrow.
MRD is a general measure of the amount of cancer in the body (tumor burden), specifically the number of cancer cells that remain in a person’s bone marrow, either during or after treatment. Measuring MRD provides a tool to detect very low levels of tumor burden. MRD is useful to evaluate in patients who have responded to therapy when their tumor burden is below what can be detected with standard methods. The detection of MRD is associated with recurrence of the disease in those patients.
