Revising Response Criteria for Multiple Myeloma Based on Clinical Trial Findings

In this special episode, Dr. Shaji Kumar from the Mayo Clinic speaks with Blood editor Dr. Laurie Sehn on a paper recently published in Blood, "Eliminating the Need for Sequential Confirmation of Response in Multiple Myeloma". The findings demonstrate eliminating the need for sequential confirmation of response in multiple myeloma. The study, involving 583 episodes of progression, found that simultaneous confirmation of disease progression using two different markers (e.g., serum protein electrophoresis and serum free light chain assay) was 98% accurate, compared to 82% for sequential confirmation. This suggests that simultaneous confirmation could improve clinical trial accuracy and reduce false censoring. The International Myeloma Working Group is set to revise its response criteria to incorporate these findings, potentially simplifying disease assessment and reducing the need for multiple blood draws.
