Mobilization of Stem Cells With Plerixafor, Chemotherapy and G-CSF in Multiple Myeloma or Non-Hodgkin's Lymphoma Patients

10 de febrero de 2014 actualizado por: Genzyme, a Sanofi Company

Treatment With Plerixafor in Multiple Myeloma or Non-Hodgkin's Lymphoma Patients to Increase the Number of Peripheral Blood Stem Cells When Given With A Mobilizing Regimen of Chemotherapy and G-CSF

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).

Descripción detallada

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.

This study was previously posted by AnorMED, Inc. In November 2006, AnorMED, Inc. was acquired by Genzyme Corporation. Genzyme Corporation is the sponsor of the trial.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: 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.
Droga: G-CSF and plerixafor
G-CSF and plerixafor were administered as described in the treatment arms.

  • AMD3100
  • Mozobil
Experimental: 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.

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.

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.

Periodo de tiempo
Overall Participant Counts of Adverse Events (AEs) Up to Twelve Months Post Transplant
Periodo de tiempo: 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.

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Número de trasplantes en los que los participantes lograron el injerto de leucocitos polimorfonucleares (PMN) el día 12 pero no después del día 21 después del trasplante de células madre de sangre periférica (PBSC)
Periodo de tiempo: 2 meses
Los participantes fueron monitoreados para el injerto de leucocitos polimorfonucleares (PMN) según el estándar de atención local. El objetivo para el injerto fue 12 días después del trasplante de PBSC y ningún trasplante tardó más de 21 días en injertarse.
2 meses
Fold (i.e., Relative) Increase in Peripheral Blood (PB) CD34+ Cells/µL
Periodo de tiempo: Days 4-5 (first dose of plerixafor to apheresis)
The fold increase was measured by fluorescence activated cell sorting (FACS) analysis and was expressed as a ratio. Fold increase = (pre-apheresis PB CD34+ cells/µL)/(pre-plerixafor dosing PB CD34+ cells/µL).
Days 4-5 (first dose of plerixafor to apheresis)
