Summary
Brief summary (as posted)
This study evaluates the safety, efficacy, and pharmacokinetics (PK) 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 who would benefit from an autologous stem cell transplant but have failed previous collections or collection attempts with a mobilization regimen of G-CSF alone, chemotherapy and G-CSF, or any other conventional therapy including cytokines, chemotherapy and cytokines and bone marrow harvests. The only change to standard of care of a mobilization regimen that includes G-CSF is the addition of a dose of AMD3100 (plerixafor) on the evening prior to each day of apheresis. Efficacy outcomes include quantification of CD34+ cells in the apheresis product and assessment of successful polymorphonuclear leukocyte (PMN) and platelet (PLT) engraftment after transplantation. PK outcomes include analysis of repeated doses of plerixafor.

- Overall Participant Counts Summarizing Adverse Events (AEs) During the Treatment Period
- timeFrame
- Day 1 to approximately day 38
- description
- Number of participants with adverse events (AEs) 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, life-threatening) and relatedness to study treatment (5 point scale from 'not related' to 'definitely related').

Inclusion Criteria: * Eligible to undergo autologous transplantation * Has failed previous collections or collection attempts with a mobilization regimen of granulocyte colony-stimulating factor (G-CSF), chemotherapy and G-CSF or any other conventional therapy including cytokines, chemotherapy and cytokines or bone marrow harvest. * Eastern Co-operative Oncology Group (ECOG) performance status of 0 or 1 * ≥3 weeks since last cycle of chemotherapy (thalidomide, dexamethasone, and Velcade™ are not considered prior chemotherapy for the purpose of this study) NOTE: Although thalidomide, dexamethasone, and Velcade™ are not considered prior chemotherapy for the purpose of this study, none are to be administered within 7 days prior to the first dose of G-CSF (see Exclusion Criteria). * The patient has recovered from all acute toxic effects of prior chemotherapy * White blood cell count (WBC) \>2.5\*10\^9/L * Absolute neutrophil count \>1.5\*10\^9/L * Platelet count \>85\*10\^9/L * Serum creatinine ≤1.5 mg/dl * Creatinine clearance \>60 ml/min * Aspartate aminotransferase (AST), alanine transaminase (ALT) and total bilirubin \<2x upper limit of normal (ULN) * Left ventricle ejection fraction \>45% (by normal echocardiogram (ECHO) or multiple gated acquisition (MUGA) scan) * Forced expiratory volume in one minute (FEV1) \>60% of predicted or diffusion lung capacity for carbon monoxide (DLCO) ≥45% of predicted * No active infection of hepatitis B or C * Negative for HIV * Signed informed consent * Women of child-bearing potential agree to use an approved form of contraception Exclusion Criteria: * Once 70 patients have enrolled, patients with diagnoses other than lymphoma are not eligible (eg, acute myeloid leukemia, chronic lymphocytic leukemia, or multiple myeloma). * A co-morbid condition which, in the view of the investigators, renders the patient at high risk from treatment complications * A residual acute medical condition resulting from prior chemotherapy * Received Neupogen™, thalidomide, dexamethasone, and/or Velcade™ within 7 days prior to the first dose of G-CSF * Brain metastases or carcinomatous meningitis * Acute infection * Fever (temperature \>38°C/100.4°F) * Hypercalcaemia (\>1 mg/dL above the ULN) * Positive pregnancy test in female patients * Lactating females * Patients of child-bearing potential unwilling to implement adequate birth control * Patients whose actual body weight exceeds 175% of their ideal body weight * Patients who previously received experimental therapy within 4 weeks of enrolling in this protocol or who are currently enrolled in another experimental protocol during the Mobilization phase
