Multiple Myeloma: Minimal Residual Disease
Patients with multiple myeloma who achieve minimal residual disease (MRD) negativity have been shown to have better outcomes compared with MRD positive patients1
Achieving deeper responses can improve outcomes2
Sustained MRD– = MRD– for 1 year
MRD is the low level of malignant cells that persist even after a complete response with myeloma treatment1
The methods used for determining MRD negativity include:
Achieving MRD negativity is associated with better outcomes such as longer PFS and OS compared with patients who are MRD positive6,7
Meta-analysis of 43 studies involving 8,114 patients: | Meta-analysis of 22 studies involving 4,462 patients: |
MRD negativity is being considered as a regulatory surrogate endpoint for PFS8,9
