Carfilzomib and lenalidomide-based treatment for transplant eligible and non-transplant eligible newly diagnosed primary plasma cell leukemia patients

Study map

Overview / Summary

Study objectives:

  • To evaluate progression-free survival in adult pPCL patients by incorporation of carfilzomib and lenalidomide in induction, consolidation, and maintenance therapy.
  • To assess overall response rate and (s)CR + VGPR ((stringent) complete and very good partial response) rate after induction therapy, after HDM, after CRd consolidation, after RIC allo-SCT or a second HDM, and during maintenance.
  • To evaluate overall survival.
  • To assess safety and toxicity.
  • To assess the prognostic value of risk factors at diagnosis, including β2-microglobulin, LDH, FISH abnormalities del1p, ampli 1q, t(4;14), t(14;16), t(11;14), ampli 9, del13q/13-, del17p as analyzed in purified bone marrow plasma cells with respect to progression-free survival.
  • To analyze the prognostic value of myeloma gene expression profiles.
  • To analyze the prognostic value of minimal-residual disease negativity.
  • To assess the prognostic value of mutations as determined by sequencing.
  • To establish the frequency of second primary malignancies (SPM).
