Adaptive Biotechnologies Corporation reports company developments tied to immune-driven diagnostics and immune medicine. The commercial-stage biotechnology company applies a proprietary platform to translate adaptive immune system genetics into clinical products, with operating activity organized around Minimal Residual Disease (MRD) and Immune Medicine.
Recurring updates for ADPT include clonoSEQ MRD testing adoption, MRD revenue trends, pharma regulatory milestone revenue, operating expense guidance, and quarterly financial results. Company news also covers immune receptor and TCR-antigen data partnerships, autoimmune and cancer-related research applications, investor conference participation, and management commentary on the company’s diagnostic and drug-development collaborations.
Adaptive Biotechnologies (ADPT) highlighted a new multiple myeloma cure definition presented at the International Myeloma Society meeting.
The definition covers newly diagnosed and relapsed patients. It requires five years in complete remission without myeloma treatment, at least four negative measurable residual disease (MRD) assessments, and no positive MRD result between them. One assessment must occur at the five-year mark. Tests must use next-generation sequencing or next-generation flow at a sensitivity of 10⁻⁶, or one myeloma cell among one million cells. PET/CT or diffusion-weighted whole-body MRI must show no disease at the start and end of the period, with no positive scan in between if additional scans are performed. Adaptive’s clonoSEQ is an FDA-cleared sequencing-based MRD test for myeloma using bone marrow.
Adaptive Biotechnologies (ADPT) reports that updated National Comprehensive Cancer Network (NCCN) Guidelines for Multiple Myeloma now provide a dedicated framework for routine minimal (or measurable) residual disease (MRD) assessment, explicitly naming its clonoSEQ assay as an FDA-cleared option. The new MYEL‑E page on Principles of MRD Testing recommends bone marrow MRD assessment using next-generation sequencing with an FDA-approved assay such as clonoSEQ or multicolor flow cytometry.
The guidelines state that MRD sensitivity of 10⁻⁶ is preferred, with 10⁻⁵ as the minimum recommended level. Recommended MRD testing timepoints now include annual assessment during maintenance therapy and testing after later treatment lines, including after CAR T‑cell therapy, emphasizing longitudinal monitoring. The updates highlight that MRD negativity and sustained MRD negativity can inform treatment escalation, de‑escalation, and maintenance decisions, while rising MRD positivity may warrant closer monitoring and clinical evaluation.
