Descripción detallada
Participants with HD who have been treated with cyto-reductive chemotherapy, who are to undergo autologous stem cell transplantation, and who meet the inclusion/exclusion criteria are eligible to enter this study. The only changes to the standard of care is the addition of plerixafor to a G-CSF mobilization regimen on the day prior to apheresis and the collection of blood samples for pharmacokinetic (PK) analysis and pharmacodynamics (PD) analysis by CD34+ fluorescence-activated cell sorting (FACS) analysis. Blood samples for PK and CD34+ FACS analyses will be obtained prior to and after the first dose of plerixafor. Participants will undergo mobilization with G-CSF (10 µg/kg daily) and will receive plerixafor (240 µg/kg) on each day prior to apheresis. Participants will be apheresed for up to 5 consecutive days in order to collect the target number of CD34+ stem cells, (≥5*10^6 cells/kg). After apheresis, all participants will be treated with high dose chemotherapy in preparation for transplantation. Participants will be transplanted with cells obtained from the G-CSF plus plerixafor mobilization regimen. In the event that a sufficient number of cells for transplantation are not obtained from the collection, cells may be retained and pooled for transplantation at the investigator's discretion.
The primary endpoint is the proportion of HD participants who collect ≥5*10^6 CD34+ cells/kg with this mobilization regimen. The secondary endpoints include the safety of this mobilization regimen, the proportion of participants who collect ≥2*10^6 CD34+ cells/kg, the change in CD34+ cells circulating in the peripheral blood after a dose of plerixafor, and the number of days of apheresis required to obtain ≥5*10^6 CD34+ cells/kg. In addition, success of the transplantation will be evaluated by measuring the time to engraftment of PMNs and PLTs. Participants will be followed for 12 months to assess transplant durability.

Experimental: Participants with Hodgkin's Disease (HD)
Participants with Hodgkin's Disease who were eligible for autologous peripheral blood stem cell transplantation.
|
Randomized participants underwent mobilization with G-CSF 10 µg/kg/day for 4 days, administered by subcutaneous injection (SC) injection.
On the evening of Day 4, participants received a dose of plerixafor 240 µg/kg, administered by SC injection.
On Day 5, participants returned to the clinic and received a morning dose of G-CSF 10 µg/kg and underwent apheresis approximately 10 to 11 hours after the dose of plerixafor (within 60 minutes after administration of G-CSF).
Participants continued to receive an evening dose of plerixafor followed the next day by a morning dose of G-CSF and apheresis for up to a maximum of 4 aphereses or until ≥ 5*10^6 CD34+ cells/kg were collected.

Overall Participant Counts of Adverse Events During the Treatment Period
Periodo de tiempo: Day 0 - approximately day 38
|
Adverse Events were graded by the investigator using the World Health Organization (WHO) Adverse Event Grading Scale and were assessed for severity (mild, moderate, severe and life-threatening) and relatedness (5 steps from 'not related' to 'definitely related') to study treatment. Time frame starts on the first day of G-CSF mobilization to the day prior to chemotherapy/ablative treatment in preparation for transplant. See the separate Serious Adverse Event section for a summary of AEs the investigator assessed as serious. |

Fold (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 using local laboratory data and was expressed as a ratio.
Fold increase = (pre-apheresis PB CD34+ cells/µL)/(pre-plerixafor dosing PB CD34+ cells/µL).
