Quantitative Analysis of Minimal Residual Disease (MRD) Shows High Rates of Undetectable MRD after Fixed-Duration Chemotherapy-Free Treatment and Serves As Surrogate Marker for Progression-Free Survival: A Prospective Analysis of the Randomized CLL14 Trial

Purpose Although minimal residual disease (MRD) is an established surrogate marker for outcomes following treatment with chemoimmunotherapy, less is known about the value of MRD in chemotherapy-free treatments in the first-line setting. We investigated the prognostic value of MRD detection after a fixed-duration treatment of venetoclax plus obinutuzumab (VenG) with respect to clinical and genetic risk factors and source of material in previously...
