MRD dynamics predicts progression and reveals a vulnerable state for immunotherapy interception in multiple myeloma.
Tracking cancer markers in blood over time identifies myeloma patients most likely to resist treatment, enabling earlier intervention with advanced therapies when they're most effective.
Analysis of 3,610 serial MRD measurements in 539 newly-diagnosed myeloma patients from three Spanish GEM trials identified five MRD dynamics subgroups — including late-sustained responders (excellent prognosis) and resurgent MRD resisters (dismal survival) — that outperform R-ISS staging and were validated in 249 additional patients. Multiomics profiling revealed immune exhaustion at MRD resistance, and preclinical models show anti-BCMA CAR-T is more effective when given preemptively at MRD resistance rather than at relapse.

Why it surfaced
Blood publication establishing MRD dynamics as strongest predictor of progression in myeloma, with 5 prognostic subgroups from 3,610 serial assessments across GEM clinical trials. CAR-T timing at MRD resistance validated preclinically — reframes treatment strategy from 'wait for relapse' to 'intercept at immune vulnerability.' High translational potential.
