NGS comparable with FC for minimal residual disease assessment

Key clinical point: Next-generation sequencing of peripheral blood is at least as effective as flow cytometry of bone marrow for assessing minimal residual disease. Major finding: At the highest sensitivity level tested, next-generation sequencing detected 18% more minimal residual disease–positive samples than did flow cytometry – 50% and 32%, respectively.

Study details: An analysis of samples from pediatric and young adult patients with B-cell acute lymphoblastic leukemia who received treatment with tisagenlecleucel on the ELIANA and ENSIGN trials.

Disclosures: The speaker reported relationships with Adaptive Biotech, Novartis, Incyte, Amgen, Bellicum Pharmaceuticals, Medac Pharma, and Miltenyi Biotec. The ELIANA and ENSIGN trials were funded by Novartis, which markets tisagenlecleucel as Kymriah.
