Chemotherapy and G-CSF for Mobilization — MOCCCA  

Multiple Myeloma Clinical Trial

Official title: A Randomized Phase II Trial Comparing Stem Cell Mobilization With Chemotherapy and Cytokine (G-CSF) Versus Cytokine (G-CSF) Alone in Myeloma Patients (MOCCCA-trial).

Status Active, not recruiting

Clinical Trial Summary

This study aims to demonstrate that the mobilization with cytokine stimulation with G-CSF alone is non-inferior as compared to the standard mobilization with chemotherapy and G-CSF while associated with fewer side effects in myeloma patients.

Clinical Trial Description

Background and Rationale High-dose chemotherapy (HDCT) with melphalan and autologous stem cell transplantation (ASCT) remains an integral component of the myeloma treatment algorithm for patients considered eligible for the procedure, nowadays performed in myeloma patients up to the age of 75 years. Until the advent of the novel agents, the initial therapy regimens commonly used were vincristine, doxorubicin, and dexamethasone (VAD) or single-agent dexamethasone, both of which shared the advantage of having little impact on stem cell mobilization and collection. Previous studies had shown that alkylating agents can potentially affect the stem cell pool and thus interfere with the ability to collect adequate numbers of stem cells. However, VAD is no longer uses nowadays, whereas current lenalidomide-containing combinations significantly affect stem cell collection. .In Switzerland, the combination of non-myeloablative chemotherapy with vinorelbine or gemcitabine and G-CSF is the current standard procedure. With the predominant use of bortezomib during induction treatment more patients have pre-existing neurotoxicity. Vinorelbine can aggravate this problem. Recently data have shown that a mobilization with gemcitabine together with G-CSF is safe and effective in myeloma patients. Whether chemotherapy is mandatory at all to achieve the same reliable and cost-effective mobilization is currently unknown. The investigators therefore consider that a direct comparison between vinorelbine/gemcitabine and G-CSF versus G-CSF alone is justified.

Objective:

The primary objective is to show non-inferiority of cytokine stimulation with G-CSF compared to chemotherapy stimulation with vinorelbine (or gemcitabine) together with G-CSF for the mobilization of autologous stem cells in myeloma patients in first remission.

Study Duration:

The anticipated total study duration is 42 months. ;
