What was measured

ORR was defined as the percentage of participants who achieved a PR rate or better (sCR + CR + VGPR + PR) during the study as defined by IMWG uniform response criteria. PR :≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 hours. CR:negative immunofixation of serum and urine, disappearance of any soft tissue plasmacytomas, and \<5% plasma cells in bone marrow. sCR: CR+normal FLC ratio and absence of clonal cells in bone marrow biopsy by immunohistochemistry. VGPR:serum and urine M-protein detectable by immunofixation but not on electrophoresis, or ≥90% reduction in serum M-protein plus urine M-protein \<100 mg/24 hours. Percentages were rounded off to the nearest decimal.

Analysis population: The FAS included all participants who received at least 1 dose, even an incomplete dose, of modakafusp alfa, in the Part 3 extension cohorts.

Groups in this outcome

Part 3 (Dose Extension): Modakafusp Alfa 240 mg

Participants received modakafusp alfa 240 mg, infusion, IV, Q4W, for each 28-day treatment cycle until disease progression or treatment discontinuation.
