Technical platform

Advances in sequencing, chemistry, and bioinformatics

The clonoSEQ Assay is differentiated from other NGS assays by groundbreaking advances in chemistry and proprietary bioinformatics.[1,2] Together, these discoveries translate into unique advantages for clinicians and patients.

Next-generation sequencing

NGS is an advance in DNA sequencing technology that enables simultaneous identification of millions of unique B-cell and T-cell receptors from a single sample.[1,2,5]

Because of its scale, high speed, and low cost, NGS makes it possible and clinically practical to characterize a tremendous breadth of genetic information at high throughput.[1,2,6]

NGS enables differentiation of very small numbers of remaining malignant cells against a background of millions of normal cells.[1,2]

Advantages in chemistry

clonoSEQ leverages proprietary innovations to solve the problem of PCR amplification bias.[1,2]

The solution is a library of synthetic molecules that enables clonoSEQ to analyze the entire immune repertoire, every time the test is used.[1,2]

That’s why clonoSEQ not only tracks sequences that are identified at diagnosis as markers of disease at diagnosis, but can also detect newly emerging clonal sequences over time.[7]

Advances in bioinformatics

The outputs of NGS are millions of raw sequencing reads. To distill all this data into MRD results that are clinically meaningful and easy to understand, clonoSEQ uses a series of proprietary algorithms that were developed based on the analysis of billions of sequences.[1,2]

clonoSEQ® is available as an FDA-cleared in vitro diagnostic (IVD) test service provided by Adaptive Biotechnologies to detect minimal residual disease (MRD) 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). Additionally, clonoSEQ is available for use in other lymphoid cancers and specimen types as a CLIA validated laboratory developed test (LDT). IGHV testing is available as a CLIA-validated LDT and has not been cleared or approved by the FDA.
