NCT06245629

Brief Summary

This project will evaluate the efficacy and safety of the conditioning regimen bortezomib-bendamustine-melphalan (BBM) in combination with autologous hematopoietic stem cell transplantation (ASCT) in relapsed multiple myeloma given from 2011 to 2018 at Uppsala University Hospital. This approach will be retrospectively compared to high dose melphalan (HDM) in the same setting in the years prior to, and following the BBM-period. Data on efficacy and safety data will be collected through systematic analysis of electronic medical records and from the Swedish Cancer Registry.

Study Arms (2)

Bortezomib-bendamustine-melphalan

Myeloma patients receiving bortezomib-bendamustine-melphalan at autologous hematopoietic stem cell transplantation first relapse.

Drug: Bortezomib-bendamustine-melphalan

high-dose melphalan

Myeloma patients receiving high-dose melphalan at autologous hematopoietic stem cell transplantation at first relapse.

Interventions

The aim of this retrospective cohort study is to evaluate the efficacy and safety of the conditioning regimen BBM compared to HDM in the setting of relapsed multiple myeloma.

Also known as: High-dose melphalan
Bortezomib-bendamustine-melphalan

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Fifty consecutive patients, who were referred to UUH for a second ASCT after relapse in multiple myeloma following HDM and ASCT between 1 Nov 2011 and 30 Jun 2018 and who received conditioning with bortezomib-bendamustine-melphalan will be included in this study. As a control group, 25 consecutive patients who were treated with HDM prior to 1 Nov 2011 and 25 consecutive patients following 30 Jun 2018. The patients will be identified through the local European Society for Blood and Marrow Transplantation (EBMT) registry at UUH.

You may qualify if:

  • Diagnosis of first relapse after previous ASCT for multiple myeloma according to the International Myeloma Working Group.
  • Treated with a second ASCT (ASCT2) as part of second line treatment at UUH.
  • Conditioning at ASCT2 with bortezomib-bendamustine-melphalan or high-dose melphalan only.

You may not qualify if:

  • Double (tandem) ASCT in first or second line treatment
  • Allogenic haematopoietic stem cell transplantation as part of first or second line therapy
  • Failure to meet the minimal dataset, defined as: (date of ASCT1 and ASCT2, date of start of induction treatment for relapsed myeloma prior to ASCT2, medical records from hospitalization for ASCT2, at least one follow-up visit (unless early death before first follow-up visit), date of progression and first treatment of relapsed multiple myeloma after ASCT2.
