Mobilization of Stem Cells With AMD3100 (Plerixafor) in Combination With G-CSF in Multiple Myeloma Patients
Study Details
Study Description
Brief Summary
This is a single-group treatment, phase IV, open label study to assess the mobilization efficacy and safety of plerixafor in combination with G- CSF in male and female participants from 18 to 75 years of age with multiple myeloma for autologous transplantation. Study Duration-Screening-up to 30-day. Intervention and CD34+cells apheresis up-to 8 day. A follow up for 30 days (+7 days) post last dose of plerixafor, or the initiation of ablative chemotherapy, or the first dose of G-CSF administration in rescue procedure, whichever occurs earlier. Study duration up to 75 days. For treatment phase visit frequency-daily.

Detailed Description
The study duration consists of: An up-to 30-day screening, an up-to 8-day intervention and CD34+ cells apheresis and a follow up for 30 days (+7 days) post last dose of plerixafor, or the initiation of ablative chemotherapy, or the first dose of G-CSF administration in rescue procedure, whichever occurs earlier
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: plerixafor Participants will receive the first dose of plerixafor by subcutaneous (SC) injection on the evening of Day 4 (10 to 11 hours (± 1 hour) prior to the start of next day's apheresis). For a maximum of 4 days, patients will continue to receive daily plerixafor in the evening, followed by a morning dose of G-CSF and apheresis for up to a maximum of 4 apheresis or until ≥ 6×106 Cluster of differentiation 34 (CD34) + cells/kg were collected. |
Drug: plerixafor + G-CSF
subcutaneous (SC) injection

Outcome Measures
Primary Outcome Measures
- The proportion of patients collecting more than or equal to 6x106 CD34+ cells/kg in 2 or fewer apheresis days [Day 5 to Day 6]
Secondary Outcome Measures
- the proportion of patients collecting more than or equal to 6x106 CD34+ cells/kg in 4 or fewer apheresis days [Day 5 to Day 8]

- the proportion of patients collecting more than or equal to 2x106 CD34+ cells/kg in 4 or fewer apheresis days [Day 5 to Day 8]
- the number of apheresis days required to reach more than or equal to 6x106 CD34+ cells/kg [Day 5 to Day 8]
- Peripheral Blood CD34+ count from Day 4 to Day 5 with the venous samples for Fluorescent activated cell sorting analysis obtained on the morning of Day 4 prior to administration of G-CSF and morning of Day 5 prior to administration of G-CSF [Day 4 to Day 5]
- Number of participants with Adverse events and Serious adverse events [Baseline to Day 30 (+7 days)]
