Brief summary:
Plerixafor, administered at a dose of 240 ug/kg, potentiates the effect of granulocyte colony-stimulating factor (G-CSF) to increase peripheral blood progenitor cells in both healthy volunteers and cancer patients. Furthermore, in cancer patients, cells collected via apheresis using Plerixafor and G-CSF have been successfully transplanted. In December 2008, Plerixafor received approval from the Food and Drug administration for use in combination with G-CSF to aid in mobilization of progenitor cells for apheresis. The proposed study is not designed to support approval of a new indication or change in the advertising for Plerixafor. The route of administration and dosage level are identical to that which is listed on the package insert. Although Plerixafor is not approved for patients with Hodgkins Lymphoma, there is no known or theoretic increased risk of the use of this drug in this patient population.

The study hypothesis for this study is that patients with a circulating CD34+ count \< 20 cells/ul after 5 days of mobilization with G-CSF alone will achieve \> or equal to 2 X 10(6)CD34+ cells/kg within 3 days of apheresis after receiving Plerixafor with G-CSF.

Detailed description:
This is a single-center, Phase 2, open-label study. All patients diagnosed with non-hodgkins lymphoma, hodgkins disease or multiple myeloma and candidates for autologous transplantation are eligible to enter into the study. The only change to the standard of care is the addition of 240 ug/kg Plerixafor following 5 days of (G-CSF) mobilization.

The results of the study will provide both numeric and categorical estimates of measurements of the safety and efficacy of Plerixafor. The primary efficacy endpoint, Treatment Success, is a binary response variable categorizing whether the patient was able to mobilize at least 2 X 10(6) CD34+ cells/kg within 3 days of apheresis.

The percentage of patients achieving Treatment Success will be summarized. All AEs will be followed for 30 days after the last apheresis or until the first dose of ablative chemotherapy, whichever occurs first. All SAEs will be followed for 6 months post-transplant or until relapse. All patients who receive at least one dose of Plerixafor will be included in all summaries of AEs.

Arms: arm 1: Patients who were unable to mobilize a minimum number of cells (CD34+ cell count \<20 cells/ul)following 5 days of G-CSF mobilization.
Interventions: intervention 1: G-CSF plus Plerixafor
Intervention descriptions: intervention 1: On Day 5 of G-CSF mobilization,

1. if the patient's peripheral CD34+ cell count is \< 7cells/µl then 240ug/kg Plerixafor will be given in the evening prior to receiving 10µg/kg G-CSF and undergoing apheresis the next morning for up to 3 days of apheresis or until ≥ 5x10(6) cells/kg are collected.
2. if the patient's peripheral CD34+ cell count is 7 to 19 cells/ul (inclusive), apheresis will be done. If the apheresis yield is \< 1.3x10(6) CD34+ cells/kg then 240ug/kg Plerixafor will be given in the evening prior to receiving 10 µg/kg G-CSF and undergoing apheresis the next morning. If the apheresis yield is at least double that on Day 5, Plerixafor followed the next morning by G-CSF and apheresis will be repeated for up to a total of 3 days of apheresis or until 5x10(6) cells/kg are collected.
