1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Elranatamab, a BCMA-CD3 bispecific antibody, has demonstrated robust activity in relapsed/refractory multiple myeloma (RRMM), but real-world outcomes remain poorly defined. We conducted a multicenter retrospective study of 130 patients treated with commercial elranatamab across nine U.S. academic centers. The cohort was heavily pretreated (91% triple-class refractory, 49% penta-refractory), with 49% previously exposed to BCMA-targeted therapies. Only 22% would have met eligibility for MagnetisMM-3 cohort A. The overall response rate (ORR) was 65%, including ≥CR in 36%. Median progression-free survival (PFS) and overall survival (OS) were 4.3 and 14.6 months, respectively, shorter than MagnetisMM-3. Elevated LDH and low hemoglobin independently predicted poor outcomes and were incorporated into the novel ALPS (Anemia-LDH Prognostic System) score, which stratified patients into distinct risk groups for ORR, OS, PFS, and duration of response. Prior BCMA exposure reduced depth of response, with inferior OS observed in those treated within one year of prior therapy. Infections occurred in 38% of patients. Intravenous immunoglobulin supplementation, modeled as a time-dependent covariate, was associated with improved infection-free survival and PFS. While the incidence of CRS was modestly lower than in MagnetisMM-3, ICANS occurred more frequently in this real-world cohort. These findings highlight the efficacy, limitations, and supportive care needs of elranatamab in a frailer, more heterogeneous real-world RRMM population.
