Objective Response Rate as Per IMWG Criteria by Investigator Assessment

MagnetisMM-3: Study Of Elranatamab (PF-06863135) Monotherapy in Participants With Multiple Myeloma Who Are Refractory to at Least One PI, One IMiD and One Anti-CD38 mAb · Source last updated 2026-05-19

This outcome was registered, but no numerical results were posted in the captured record.

Measure: Not reported
Unit: Not reported
Interval / dispersion: Not reported
Time frame: From date of first dose until confirmed disease progression, death, start of new anticancer therapy, whichever occurred first (up to approximately 20.14 months)

What was measured

ORR: % of participants with best overall response of confirmed stringent complete response (sCR), CR, very good partial response (VGPR) or PR per IMWG criteria. sCR: CR \& normal serum free light chain (sFLC) ratio \& absence of clonal cells in BMB/BMA by IH, IF, or flow cytometry. CR: negative immunofixation on serum \& urine, disappearance of any soft tissue plasmacytoma \& \<5% plasma cells in BMA, if disease measurable by sFLC only, preceding criteria plus normal sFLC ratio. VGPR: Serum \& urine M-protein detectable by immunofixation but not on electrophoresis; or \>=90% reduction in serum M-protein \& urine M-protein level \<100mg/24h. PR: \>=50% reduction in serum M-protein \& reduction in 24h urinary M-protein by \>=90% or \<200 mg/24h. If serum \& urine M-protein were unmeasurable, VGPR \& PR: \>=90% \& \>=50% decrease in difference respectively between involved \& uninvolved sFLC levels \& if present at baseline, \>=90% \& \>=50% reduction in soft tissue plasmacytomas' size.
