AMD3100 (Plerixafor) Given to NHL and MM Patients to Increase the Number of PBSCs When Given a Mobilizing Regimen of G-CSF

Genzyme, a Sanofi Company22 enrolled

Overview

This study evaluates the safety and efficacy of plerixafor given in addition to granulocyte-colony stimulating factor (G-CSF) for collection of peripheral blood stem cells (PBSCs) for autologous transplantation in patients with non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM). Efficacy outcomes include evaluation of fold increase in circulating CD34+ cells from just before the first plerixafor injection to 10-11 hours post plerixafor (just before apheresis) and assessment of successful polymorphonuclear leukocyte (PMN) engraftment after transplantation. Data from this protocol will assist in the determination of the dosing schedule for future studies.

Participants with NHL and MM who have undergone prior cyto-reductive chemotherapy, are to be autologously transplanted, and meet the inclusion/exclusion criteria are eligible to enter the study. The only change to the standard of care is the addition of plerixafor to a granulocyte colony-stimulating factor (G-CSF) mobilization regimen on the day prior to apheresis. Participants will undergo mobilization with G-CSF (10 mcg/kg each day) and will receive plerixafor (240 mcg/kg) in the evening prior to apheresis. Participants will undergo apheresis for up to 5 consecutive days in order to collect the target number of CD34+ stem cells (≥ 5\*10\^6 CD34+ cells/kg for either single or tandem transplant). 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 and plerixafor mobilization regimen. The increase in CD34+ cells in the peripheral blood from the time of the plerixafor dose to just prior to apheresis and the number of CD34+ cells in the apheresis product will be measured. Success of the transplantation(s) will be evaluated by the time to engraftment of polymorphonuclear leukocytes (PMN). A subpopulation will have pharmacokinetic and pharmacodynamic analysis done.

G-CSF Plus PlerixaforDRUG

Participants underwent mobilization with G-CSF 10 µg/kg/day for 4 days, administered by subcutaneous injection (SC) injection each morning. 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 5 aphereses or until ≥ 5\*10\^6 CD34+ cells/kg were collected.

Exclusion Criteria: * • Patients who have failed previous collections * Brain metastases or carcinomatous meningitis * History of ventricular arrhythmias * A co-morbid condition which, in the view of the investigator, renders the patient at high risk for treatment complications * A residual acute medical condition resulting from prior chemotherapy * Acute infection * Fever (temp \>38°C/100.4°F) * Patients whose actual body weight exceeds 150% of their ideal body weight * History of paresthesias (at least Grade 2) * Patients who previously received experimental therapy within 4 weeks of enrolling in this study or who are currently enrolled in another experimental study during the mobilization period * Positive pregnancy test in female patients * Lactating females * Patients of child-bearing potential unwilling to implement adequate birth control. * Patients who have deterioration of their clinical status or laboratory parameters between the time of enrolment and transplant (such that they no longer meet entry criteria) may be removed from study at the discretion of the treating physician, principal investigator, or sponsor.

Outcomes

Primary Outcomes

Number of Participants in Overall Safety Summary of Treatment Emergent Adverse Events (TEAE)

Number of participants with treatment emergent adverse events (TEAEs) collected from Day 1 (start of G-CSF mobilization) to the day before starting chemotherapy. AEs were graded by the investigator using the World Health Organization (WHO) Adverse Event Grading Scale and were assessed for severity (mild, moderate, severe) and relatedness to study treatment (5 point scale from 'not related' to 'definitely related').

Time frame: Day 1 to approximately Day 38 (before start of chemotherapy)

Secondary Outcomes

Number of Participants Who Had a ≥ 2-fold Increase in Circulating CD34+ Cells

To determine if NHL and MM patients mobilized with G-CSF (10 µg/kg QD) plus plerixafor will have a ≥2-fold increase in circulating CD34+ cells from time 0 to 11 hours after a dose of plerixafor.

Time frame: Time 0 to 11 hours after the first dose of plerixafor

Number of Transplants Resulting In Polymorphonuclear Leukocyte (PMN) Engraftment by Day 12 But No Later Than Day 21 Post-Transplant

Participants were monitored for polymorphonuclear leukocyte (PMN) engraftment as per the local standard of care. The target for engraftment was 12 days after PBSC transplant and no transplant taking longer than 21 days for engraftment.

Time frame: 2 months

Tumor Cell Mobilization in Non-Hodgkin's Lymphoma (NHL) Participants Following Plerixafor Treatment

In a subpopulation of NHL participants, the mobilization of NHL cells was to be evaluated. None of the samples were analyzed due to sample degradation.

Time frame: Prior to the first (Day 4) and last dose of plerixafor, immediately prior to each apheresis, and 24 hours after the last apheresis.

Single-dose Maximum Observed Concentration of Plerixafor (Cmax)

Evaluation of Cmax following a single dose of 240 µg/kg plerixafor administered after 4 days of G-CSF mobilization. Cmax was determined from direct observation of the data.
