Brief Summary:
Participants with Hodgkin's Disease (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 efficacy, safety and pharmacokinetic (PK) study. The only changes to the standard of care is the addition of plerixafor to a granulocyte-colony stimulating factor (G-CSF) mobilization regimen on each day prior to apheresis. The purpose of this protocol is to determine the proportion of participants who reach a target number of CD34+ stem cells (≥5*10^6 cells/kg) after hematopoietic stem cell mobilization with G-CSF and plerixafor. Safety and PK parameters are also collected.

Hodgkin's Disease Drug: G-CSF Plus Plerixafor Phase 2

Detailed Description:

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.

Arm Intervention/treatment
Experimental: Participants with Hodgkin's Disease (HD)
Participants with Hodgkin's Disease who were eligible for autologous peripheral blood stem cell transplantation.
Drug: G-CSF Plus Plerixafor
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.

Primary Outcome Measures :
  1. Proportion of Participants Who Achieved ≥5*10^6 CD34+ Cells/kg Following Treatment With Plerixafor and G-CSF [ Time Frame: Day 5 up to Day 9 ]
    The proportion of total participants who mobilized ≥5*10^6 CD34+ cells/kg based on data from local laboratories.


Secondary Outcome Measures :
  1. Overall Participant Counts of Adverse Events During the Treatment Period [ Time Frame: 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.


  2. Proportion of Participants Who Achieved ≥2*10^6 CD34+ Cells/kg Following Treatment With Plerixafor and G-CSF [ Time Frame: Day 5 up to day 9 ]
    The proportion of total participants who mobilized ≥2*10^6 CD34+ cells/kg based on data from local laboratories.

  3. Fold (Relative) Increase in Peripheral Blood (PB) CD34+ Cells/µL [ Time Frame: 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).

  4. Participant Counts Grouped by Number of Apheresis Days Required to Collect ≥ 5*10^6 CD34+ Cells/kg [ Time Frame: Day 5 up to day 9 ]
    Counts of participants grouped by the number of apheresis days needed to collect a target for transplantation of ≥5*10^6 CD34+ cells/kg as determined by local laboratory data.

  5. Number of Days Post-Transplantation to Polymorphonuclear Leukocyte (PMN) Engraftment [ Time Frame: Up to Month 13 (up to 12 months post transplant) ]
    Median number of days to PMN engraftment following transplantation. 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.

  6. Number of Days Post Transplantation to Platelet (PLT) Engraftment [ Time Frame: Up to Month 13 (up to 12 months post transplant) ]
    Median number of days to PLT engraftment following transplantation. Engraftment success was evaluated according to local site practice. Time to engraftment corresponded to the first day that criteria were met.

  7. Number of Participants With a Durable Graft at 12 Months [ Time Frame: 13 months ]
    Graft durability was assessed by the Investigator based on complete blood count (CBC) and differential analyses at 12 months post transplantation. A graft was considered durable if blood counts were normal (acceptable) and still met the criteria for PLT and PMN engraftment.

  8. Maximum Plasma Concentration (Cmax) Following a Single Dose of Plerixafor [ Time Frame: Day 4 ]
    Maximum plasma concentration (Cmax) of plerixafor following the first single dose of 240 ug/kg plerixafor administered.

  9. Time to Maximum Plasma Concentration (Tmax) Following a Single Dose of Plerixafor [ Time Frame: Day 4 ]
    Time to maximum plasma concentration (Tmax) of plerixafor following the first single dose of 240 ug/kg plerixafor was determined from direct observation of the data.

  10. Half-life (T1/2) Following a Single Dose of Plerixafor [ Time Frame: Day 4 ]
    Plasma elimination half-life (T1/2) following a single dose of 240 ug/kg plerixafor.

  11. Area Under the Plasma Concentration-time Curve From 0 to 10 Hours (AUC0-10) Following a Single Dose of Plerixafor [ Time Frame: Days 4-5 ]
    Area under the plasma concentration-time curve from 0 to 10 hours (AUC0-10) following the first single dose of 240 ug/kg plerixafor.

  12. Apparent Clearance (CL/F) of Single-dose Plerixafor [ Time Frame: Day 4-5 ]
    Apparent clearance was calculated the mean dose of plerixafor divided by the area under the plasma concentration-time curve from 0 hours to infinity (AUC0-inf).

  13. Apparent Volume of Distribution (Vz/F) Following a Single-dose of Plerixafor [ Time Frame: Day 4 ]
    The volume of distribution (Vz/F) was calculated as apparent clearance divided by the terminal elimination rate constant.
