Multiple Myeloma | Drug: Granulocyte colony-stimulating factor plus plerixafor Drug: Granulocyte colony-stimulating factor plus placebo | Phase 3 |
A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Currently filgrastim (G-CSF), a colony stimulating factor, is used to cause the growth and mobilization of stem cells from bone marrow to peripheral blood, which can then be collected from the peripheral blood by a process called apheresis. Plerixafor aids in the release of the stem cells from the bone marrow into the peripheral blood, possibly allowing for a more rapid collection of a larger number of stem cells from the peripheral blood. Larger stem cell doses for transplantation correlate to faster recovery times after high dose chemotherapy followed with stem cell transplantation. This study is intended to determine whether the combination of plerixafor with filgrastim (G-CSF)is better than filgrastim (G-CSF) alone in helping multiple myeloma patients collect at least 6 million stem cells in two or less apheresis sessions.

Experimental: G-CSF plus plerixafor |
Drug: Granulocyte colony-stimulating factor plus plerixafor
Participants underwent mobilization with granulocyte colony-stimulating factor (G-CSF) (10 µg/kg/day) for 4 days, administered by subcutaneous (SC) injection. On the evening of Day 4, participants received plerixafor (240 µg/kg), administered by SC injection. On Day 5, participants received a morning dose of G-CSF (10 µg/kg) and underwent apheresis approx. 10 to 11 hours after the dose of plerixafor (within 60 minutes of G-CSF administration). Participants continued to receive an evening dose of plerixafor followed by a morning dose of G-CSF and apheresis for up to 4 aphereses or until ≥ 6*10^6 CD34+ cells/kg were collected. Participants who participated in the rescue procedure underwent an additional daily treatment with plerixafor (240 µg/kg) and apheresis for up to 4 days.

Placebo Comparator: G-CSF plus placebo |
Drug: Granulocyte colony-stimulating factor plus placebo
Participants underwent mobilization with granulocyte colony-stimulating factor (G-CSF) (10 µg/kg/day) for 4 days, administered by subcutaneous (SC) injection. On the evening of Day 4, participants received placebo, administered by SC injection. On Day 5, participants received a morning dose of G-CSF (10 µg/kg) and underwent apheresis approx. 10 to 11 hours after the dose of placebo (within 60 minutes of G-CSF administration). Participants continued to receive an evening dose of placebo followed by a morning dose of G-CSF and apheresis for up to 4 aphereses or until ≥ 6*10^6 CD34+ cells/kg were collected. Participants who participated in the rescue procedure underwent an additional daily treatment with plerixafor (240 µg/kg) and apheresis for up to 4 days. |
- Proportion of Participants Achieving a Target of ≥ 6*10^6 CD34+ Cells/kg in 2 or Fewer Days of Apheresis. [ Time Frame: up to Day 6 ]Proportion of participants achieving a target of ≥ 6*10^6 CD34+ cells/kg in 2 or fewer days of apheresis. Central lab data were taken from Days 5 to 6 of the Treatment/Apheresis period. Each participant's value was calculated as the sum of all daily values collected over the 2 apheresis days.
- Number of Participants With Adverse Events [ Time Frame: up to Day 38 ]Number of participants with treatment emergent adverse events (AEs). The timeframe for treatment emergent AEs is defined as Day 1 (start of G-CSF Mobilization) to the day before starting chemotherapy (approximately 38 days later). AEs were reported regardless of relationship to study treatment. The investigator graded each AE using the World Health Organization (WHO) Adverse Event Grading Scale. AEs of Grade 3 were considered severe and Grade 4 were considered life-threatening.
- Proportion of Participants Achieving a Target of ≥ 6*10^6 CD34+ Cells/kg in 4 or Fewer Days of Apheresis. [ Time Frame: up to Day 8 ]Proportion of participants achieving a target of ≥ 6*10^6 CD34+ cells/kg in 4 or fewer days of apheresis. Central lab data were taken from Days 5 to 8 of the Treatment/Apheresis period. Each participant's value was calculated as the sum of all daily values collected over the 4 apheresis days.
- Proportion of Participants Achieving a Target of ≥ 2*10^6 CD34+ Cells/kg in 4 or Fewer Days of Apheresis. [ Time Frame: up to Day 8 ]Proportion of participants achieving a target of ≥ 2*10^6 CD34+ cells/kg in 4 or fewer days of apheresis. Central lab data were taken from Days 5 to 8 of the Treatment/Apheresis period. Each participant's value was calculated as the sum of all daily values collected over the 4 apheresis days.
- Median Number of Days to ≥6*10^6 CD34+ Cells/kg [ Time Frame: up to Day 8 ]The Kaplan Meier estimate of median number of days (number of days at which 50% of participants have experienced the event, accounting for censored values) in each treatment arm to collect an optimum number of cells (≥6*10^6 CD34+ cells/kg) for transplantation.
- Median Number of Days to Polymorphonuclear (PMN) Cell Engraftment [ Time Frame: Up to Month 13 ]The Kaplan Meier estimate of median number of days to PMN engraftment (number of days at which 50% of participants have experienced the event, accounting for censored values) was a secondary efficacy endpoint. Engraftment was defined as PMN counts ≥ 0.5*10^9/L for 3 consecutive days or ≥ 1.0*10^9/L for 1 day. Time to engraftment corresponded to the first day that the criteria were met and was evaluated up to 12 months post transplant.
- Median Number of Days to Platelet (PLT) Engraftment [ Time Frame: Up to Month 13 ]The Kaplan Meier estimate of median number of days to PLT engraftment (number of days at which 50% of participants have experienced the event, accounting for censored values) was a secondary efficacy endpoint. Engraftment was defined as ≥ 20*10^9/L without transfusion for the preceding 7 days. Time to engraftment corresponded to the first day that the criteria were met and was evaluated up to 12 months post transplant.
- Graft Durability at 100 Days Post Transplantation [ Time Frame: approximately Day 138 ]The proportion of participants maintaining a durable graft at 100 days post-transplantation by at least 2 of the following criteria (without erythropoietin (EPO), G-CSF, or transfusions): (1) a platelet count >50000/µL without transfusion for at least 2 weeks, (2) hemoglobin >=10g/dL for at least 1 month, (3) and absolute neutrophil count >1000/µL for at least 1 week.
- Graft Durability at 6 Months Post Transplantation [ Time Frame: approximately Month 7 ]The proportion of participants maintaining a durable graft at 6 months post-transplantation by at least 2 of the following criteria (without erythropoietin (EPO), G-CSF, or transfusions): (1) a platelet count >50000/µL without transfusion for at least 2 weeks, (2) hemoglobin >=10g/dL for at least 1 month, (3) and absolute neutrophil count >1000/µL for at least 1 week.
- Graft Durability at 12 Months Post Transplantation [ Time Frame: approximately Month 13 ]The proportion of participants maintaining a durable graft at 12 months post-transplantation by at least 2 of the following criteria (without erythropoietin (EPO), G-CSF, or transfusions): (1) a platelet count >50000/µL without transfusion for at least 2 weeks, (2) hemoglobin >=10g/dL for at least 1 month, (3) and absolute neutrophil count >1000/µL for at least 1 week.
