Overview

Non-randomized phase 2 trial demonstrates improved progression-free survival with carfilzomib and lenalidomide in primary plasma cell leukaemia, highlighting the ongoing need for novel...

Key Points

  • To evaluate whether integrating carfilzomib and lenalidomide into induction, consolidation, and maintenance regimens improves outcomes for newly diagnosed primary plasma cell leukaemia.
  • Non-randomised, multicentre, phase 2 study (EMN12/HOVON-129; NTR5350) conducted across 19 academic centres in seven European countries among 61 newly diagnosed patients.
  • Younger patients (aged 18–65 years, n=36) received carfilzomib, lenalidomide, and dexamethasone (KRd) induction, autologous haematopoietic stem-cell transplantation, KRd consolidation, and carfilzomib–lenalidomide maintenance.
  • Older patients (aged ≥66 years, n=25) received eight cycles of KRd induction followed by continuous carfilzomib and lenalidomide maintenance until disease progression.
  • Median progression-free survival was 15·5 months (95% CI 9·4–38·4) with median follow-up of 43·5 months in younger patients, and 13·8 months (95% CI 9·2–35·5) with median follow-up of 32·0 months in older patients.
  • Grade 3 or higher adverse events during the initial four KRd cycles included infections (6% of younger vs 32% of older patients) and respiratory events (6% vs 16%).
  • Treatment-related serious adverse events occurred in 72% of younger and 76% of older patients, resulting in treatment-related mortality in 0% of younger and 12% (n=3) of older patients.
