Brief summary

This phase III randomized trial compares three different peripheral stem cell mobilization regimens for patients with multiple myeloma who have received primary induction therapy or other therapies. Up to 180 patients will be enrolled. Patients eligible for treatment will be randomized to one of the three following mobilization regimens: Arm A = VELCADE, CYCLOPHOSPHAMIDE, & G-CSF Arm B = VELCADE & G-CSF Arm C = CYCLOPHOSPHAMIDE & G-CSF Arm D = PLERIXAFOR & G-CSF Arm E = PLERIXAFOR, VELCADE, & G-CSF

Detailed description

PRIMARY STUDY OBJECTIVES • To compare the efficacy of the following peripheral stem cell mobilization regimens for MM: i. High dose cyclophosphamide, VELCADE, and G-CSF ii. VELCADE and G-CSF iii. High dose cyclophosphamide and G-CSF SECONDARY STUDY OBJECTIVES • To evaluate biomarkers as surrogate markers of mobilization in each arm To evaluate changes in tumor mass as defined by standard response parameters. To evaluate the safety of each of the arms.

Outcome results

Primary

Number of Patients Able to Collect >=6 x 106 CD34+ Cells/kg in <= 2 Collections.

The primary endpoint in all five treatment arms is the percentage of patients who are able to achieve greater than 6 x 106 CD34+ stems cells/kg harvested (defined as effectiveness). Note that no patients were enrolled Arm D and Arm E.

Time frame: 36 months

Population: Arm A: 20 patients were enrolled but only 17 were evaluable. Arm C: 23 patients enrolled but only 21 were evaluable. Arm D and Arm E of the study did not accrue any subjects, therefore the number of participants analyzed for this outcome measure is 0 for both arms.

Comparison: Arm B was initially closed due to low accrual, and Arms D and E were also closed due to no accrual. Arms A and C also had very low accrual. Therefore, the comparison of the primary outcome between Arms A and C is for exploratory purposes only.p-value: 0.995% CI: [-0.32, 0.28]Chi-squared
Secondary

Number of Patients Who Achieved Neutrophil Recovery After Melphalan 200 Based Transplant

Number of patients who achieved neutrophil recovery after Melphalan 200 based transplant in 20 days or fewer. Neutrophil recovery is defined as an absolute neutrophil count of greater than 0.5 k/uL for three consecutive days.

Time frame: 20 days post-transplant

Population: Data analyzed only for patients who went on to receive a stem cell transplant after mobilization. 25 subject did not receive a stem cell transplant after mobilization and therefore are not included in the analysis. However, no statistical test can be performed because the outcome proportion was 100% in each group.
