简要总结
Patients with multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL) will be mobilized with chemotherapy and G-CSF plus plerixafor (AMD3100). The purpose of this protocol is to determine if plerixafor given after chemotherapy and G-CSF mobilization regimen is safe, if it can increase the circulating levels of peripheral blood stem cells (PBSCs) by ≥ 2-fold before apheresis, and if transplantation with the apheresis product was successful, as measured by time to engraftment of polymorphonuclear leukocytes (PMNs) and platelets (PLTs).
详细描述
An open label, multi-center, phase 2 study was conducted in patients with MM or NHL who were to be treated with peripheral blood stem cells (PBSC) autologous transplantation. The only change to the standard of care was the addition of plerixafor to a mobilization regimen of chemotherapy and G-CSF. Patients were first given a mobilizing regimen of chemotherapy as per local practice guidelines and G-CSF (at customary doses) and apheresis was performed. After the first apheresis, plerixafor was given at 10PM, 10-11 hours before the second apheresis the next day or in the morning of the second day, 6 hours before the second apheresis. The change in the patient's peripheral CD34+ cell count between the plerixafor dose and the start of apheresis was measured. The apheresis yields on Day 1 and Day 2 were compared.

研究组 & 干预措施
Plerixafor PM
Participants received chemotherapy and G-CSF mobilization for 7 days according to standard procedures at the study center. When participants achieved a target CD34+ count of ≥20 cells/µL, apheresis began. G-CSF was given daily in the morning on the days of apheresis. After the first apheresis, plerixafor (240 µg/kg) was administered each evening (approximately 10pm) followed by apheresis 10 to 11 hours later for up to 4 consecutive days.
Called 'Cohort A' in protocol, study report and publications.
干预措施: G-CSF and plerixafor (Drug)
Plerixafor AM
Participants received chemotherapy and G-CSF mobilization for 7 days according to standard procedures at the study center. When participants achieved a target CD34+ count of ≥20 cells/µL, apheresis began. G-CSF was given daily in the morning on the days of apheresis. The morning of the second day after the first apheresis, plerixafor (240 µg/kg) was administered followed by apheresis 6 hours later. Plerixafor (240 µg/kg) was administered in the morning followed by apheresis 6 hours later for up to 4 consecutive days.
Called 'Cohort B' in protocol, study report and publications.
干预措施: G-CSF and plerixafor (Drug)
Low CD34+ Count/ Plerixafor PM
Participants received chemotherapy and G-CSF mobilization for 7 days according to standard procedures at the study center. If participants had a CD34+ count of >=10 cells/µL but <20 cells/µL on 2 consecutive days, plerixafor (240 µg/kg) was given in the evening. G-CSF was administered and apheresis performed in the morning. Plerixafor (240 µg/kg) administered in the evening followed by G-CSF and apheresis 10 to 11 hours later was repeated for up to 4 consecutive days.
Called 'Cohort C' in protocol, study report and publications.
干预措施: G-CSF and plerixafor (Drug)
Plerixafor After Chemo
This investigational cohort evaluated the effect of administering plerixafor before white blood cell recovery.
Participants received mobilizing chemotherapy, followed by 5 consecutive days of G-CSF (10 µg/kg). Starting on the sixth day, participants received G-CSF (10 µg/kg) plus plerixafor (240 µg/kg) daily for up to 3 consecutive days. If CD34+ counts reached >= 20 cells/µL 6 hours after any of the 3 plerixafor doses, apheresis began. If not, G-CSF administration continued until the participant qualified for one of the other treatment arms.
Called 'Investigational Cohort' in protocol, study report and publications.

结局指标
主要结局
Overall Participant Counts of Adverse Events (AEs) Up to Twelve Months Post Transplant
时间窗: 13 months
Safety assessment was based on the incidence of adverse event reports. Participant count of AEs (Adverse Events) by severity and by relationship to study drug. AEs were reported regardless of relationship to study treatment. The investigator graded each AE using the World Health Organization (WHO) Adverse Event Grading Scale and provided assessments of seriousness and relatedness to study treatment.
次要结局
- Fold (i.e., Relative) Increase in Peripheral Blood (PB) CD34+ Cells/µL(Days 4-5 (first dose of plerixafor to apheresis))
- Number of Transplants in Which Participants Achieved Polymorphonuclear Leukocyte (PMN) Engraftment by Day 12 But No Later Than Day 21 Post Peripheral Blood Stem Cell (PBSC) Transplant(2 months)
