Abstract

In newly diagnosed multiple myeloma (NDMM), measurable residual disease (MRD) status is prognostically important, but its role in treatment decisions remains unclear. In a phase 2 trial, we assessed daratumumab, carfilzomib, lenalidomide, and dexamethasone (Dara-KRd) induction followed by a next-generation sequencing-based MRD-adapted strategy. The primary outcome was complete response (CR) and stringent CR (≥CR) after induction. Flow cytometry was used to profile T cells. Among 39 patients, 21 (54%) achieved ≥CR after induction (P = .375), with MRD-negative rates of 59% (10-5) and 41% (10-6). Patients who were MRD-negative (n = 24, group A) received lenalidomide maintenance, showing sustained MRD negativity in 14 of 18 (77.8%) for ≥12 cycles. MRD-positive transplant-eligi
