Why it matters

Achieving MRD-negative complete response is associated with improved long-term outcomes in multiple myeloma. IberDd offers a novel, all-oral (except daratumumab) regimen with a significantly higher MRD-negative CR rate than a standard triplet, potentially improving depth of response in relapsed/refractory disease.
