The combination of elotuzumab, pomalidomide, and dexamethasone (EloPd) was investigated as part of the ELOQUENT-3 (NCT02654132) trial leading to its approval in patients with relapsed/refractory multiple myeloma (RRMM) who have received ≥2 prior therapies, including lenalidomide and a proteasome inhibitor.1

Here, we summarize a publication by Gentile et al.1 in Haematologica on real-world experiences and outcomes in patients with RRMM treated with EloPd compared with the clinical trial data from ELOQUENT-3.

Study design1

  • Data was collected from 200 patients with RRMM treated with EloPd across multiple Italian centers outside of clinical trials
  • Outcome data was compared with the ELOQUENT-3 trial data to establish real-world EloPd efficacy and safety
  • All patients were treated with EloPd according to the marketing approval

Key findings1

  • The overall response rate was 55.4% (Figure 1) with a median time to response of 1.8 months, comparable with ELOQUENT-3 at 53%
  • Median progression-free survival (PFS) was 7 months, shorter than what was observed in ELOQUENT-3 which was 10.3 months
  • At a median follow-up of 9 months, 126 patients had stopped treatment with EloPd; 88.9% of these were due to disease progression
  • Median overall survival was observed at 17.5 months compared with 29.8 months observed in ELOQUENT-3
  • The characteristic associated with the poorest 12-month PFS rate was an International Staging System Stage III at 24.2% and a hazard ratio of 2.55 (Figure 2)
  • Adverse events and toxicity profiles were comparable with ELOQUENT-3, and no significant differences were observed depending on age

Key learnings

  • Real world data in patients with RRMM treated with EloPd is comparable with ELOQUENT-3 trial data.
  • Few key outcomes, such as PFS, differed from clinical trial data. This is likely attributed to stringent inclusion and exclusion criteria in clinical trials leading to a non-representative population.
  • Results from this retrospective trial provide additional evidence to support the use of EloPd in patients with RRMM who have received ≥2 prior therapies, including lenalidomide and a proteasome inhibitor.
