Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as melphalan, use different ways to stop cancer cells from dividing so they stop growing or die. Stem cell transplant using stem cells from the patient may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. Giving colony-stimulating factors, such as G-CSF or pegfilgrastim, helps stem cells move from the bone marrow to the blood so they can be collected. It is not yet known which regimen is more effective in treating multiple myeloma.

PURPOSE: This randomized phase II trial is studying how well high-dose chemotherapy followed by stem cell transplant works in treating patients with newly diagnosed stage I, stage II, or stage III multiple myeloma.

Description:

OBJECTIVES:

Primary

• Compare engraftment of peripheral blood progenitor cells (PBPCs) mobilized by 2 different fixed doses of pegfilgrastim versus a by-weight dose of filgrastim (G-CSF).

Secondary

• Determine the ability of 2 different fixed doses of pegfilgrastim to mobilize PBPCs.

• Determine the safety of pegfilgrastim during PBPC mobilization and collection.

• Determine the effect of different induction chemotherapy regimens on autologous progenitor cell transplantation.

OUTLINE: This is a multicenter study. Patients are stratified by type of induction chemotherapy (Thal/Dex vs VAD vs Vel-Dex vs VTD) and by stage of disease according to International Prognostic Index criteria (stage I [i.e., beta-2 microglobulin < 3.5 and albumin > 35] vs stages II and III).

• Induction therapy: Patients receive 3-4 courses of 1 of the following regimens:

• VAD: Patients receive vincristine, doxorubicin hydrochloride, and dexamethasone.

• Thal/Dex: Patients receive thalidomide and dexamethasone.

• Vel-Dex: Patients receive bortezomib and dexamethasone.

• VTD: Patients receive bortezomib, thalidomide, and dexamethasone. Patients achieving complete, partial, or minimal response after 3-4 courses of induction therapy proceed to peripheral blood progenitor cell (PBPC) mobilization 17 days after completion of induction therapy.

• PBPC mobilization: Patients are randomized to 1 of 3 arms.

• Arm I: Patients receive filgrastim subcutaneously (SC) once daily until the final leukapheresis.

• Arm II: Patients receive a single dose of pegfilgrastim SC.

• Arm III: Patients receive pegfilgrastim as in arm II at a higher dose.

• Leukapheresis: Patients undergo up to 3 leukaphereses to obtain adequate numbers of CD34-positive filgrastim- or pegfilgrastim-mobilized PBPCs for engraftment. Patients achieving a sufficient number of collected PBSCs proceed to conditioning chemotherapy.

• Conditioning chemotherapy: Patients receive high-dose melphalan* IV over 1-2 days. Patients then proceed to PBPC transplantation.

NOTE: *Patients ≥ 65 years old receive melphalan at a lower dose.

• Autologous PBPC transplantation: Patients undergo infusion of PBPCs on day 0. Patients in all arms receive G-CSF support beginning on day 1 after PBPC transplantation and continuing until blood counts recover for 3 consecutive days.

After completion of study therapy, patients are followed for up to 100 days post-transplantation.
