A Study to Learn About the Medicine (Called Elranatamab) in People With Relapsed Refractory Multiple Myeloma

This study is to understand how well elranatamab (PF-06863135) may be used for relapsed refractory multiple myeloma (RRMM). Sometimes MM might improve at first, but then gets resistant to the treatment and starts growing again (known as relapsed refractory). This study medicine will be compared with standard-of-care (SOC) therapies used in real-world clinical practice. For people receiving elranatamab, we will use data from the phase 2 clinical trial (MagnetisMM-3). We will also use data from two real-world databases, representing the SOC in clinical practice. This study does not seek any participants for enrollment. We will compare the experiences of people receiving elranatamab to people receiving SOC therapies. This way, it will help us to know how well elranatamab can be used for RRMM treatment.

Primary outcomes

  1. Objective Response Rate (ORR)-Unweighted Analysis

    Time frame: From index date until first documentation of progression, death, or the start of new anticancer therapy (median follow-up of 10.4 months for study C1071003 cohort A, 8.8 months and 7.7 months for COTA and Flatiron Health cohorts)

    ORR was the percentage of participants with objective response (OR) per IMWG criteria. For the analysis set of participants from Study C1071003 and COTA, OR was partial response (PR) or better (stringent complete response [sCR]+complete response [CR]+very good partial response [VGPR]+PR). For Study C1071003 and Flatiron Health, OR was PR or better (at least VGPR+PR). 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 measured by sFLC only, preceding criteria + normal sFLC ratio. VGPR: Serum & urine M-protein detectable by immunofixation but not on electrophoresis; or >=90% reduction in serum & 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. Clopper-Pearson two-sided 95% exact confidence intervals were estimated.

  2. Objective Response Rate-Comparison Between Elranatamab in Study C1071003 Cohort A and COTA Cohort Using Inverse Probability of Treatment Weights (IPTW) Analysis

    Time frame: From index date until first documentation of progression, death, or the start of new anticancer therapy (median follow-up of 10.4 months for study C1071003 cohort A, 8.8 months and 7.7 months for COTA and Flatiron Health cohorts)

    ORR was the percentage of participants with an OR per IMWG criteria. For the analysis set of participants from Study C1071003 and COTA, the OR was defined as PR or better (sCR + CR + VGPR + PR). For Study C1071003 and Flatiron Health, OR was defined as PR or better (at least VGPR + PR). 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 measured by sFLC only, preceding criteria + normal sFLC ratio. VGPR: Serum & urine M-protein detectable by immunofixation but not on electrophoresis; or >=90% reduction in serum & 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. Analysis was performed using IPTW method to balance participant characteristics among reporting groups.

    ORR was the percentage of participants with an OR per IMWG criteria. For the analysis set of participants from Study C1071003 and COTA, the OR was defined as PR or better (sCR + CR + VGPR + PR). For Study C1071003 and Flatiron Health, OR was defined as PR or better (at least VGPR + PR). 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 measured by sFLC only, preceding criteria + normal sFLC ratio. VGPR: Serum & urine M-protein detectable by immunofixation but not on electrophoresis; or >=90% reduction in serum & urine M-protein level <100mg/24h.
