mobilization of stem cells with amd3100 (plerixafor) and g-csf in non-hodgkin's lymphoma and multiple myeloma patients

Conditions: Lymphoma, Non-Hodgkin; Multiple Myeloma

Summary: 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. the number of apheresis sessions required to obtain ≥ 5\*10\^6 cd34+ cells will also be measured. success of the transplantation(s) will be evaluated by the time to engraftment of polymorphonuclear leukocytes (pmn) and platelets (plt). participants will be followed for durability of their transplant for 12 months following transplantation. this study was previously posted by anormed, inc. in november 2006, anormed, inc. was acquired by genzyme corporation. genzyme corporation is the sponsor of the trial.

Eligibility criteria:
inclusion criteria: * diagnosis of non-hodgkin's lymphoma (nhl) or multiple myoloma (mm) eligible for autologous transplantation * no more than 3 prior regimens of chemotherapy * more than 4 weeks since last cycle of chemotherapy. patient recovered from all acute toxic effects of prior chemotherapy. * eastern cooperative oncology group (ecog) performance status of 0 or 1 * white blood cell (wbc) count \>3.0\*10\^9/l * absolute polymorphonuclear cells (pmn) count \>1.5\*10\^9/l * platelet (plt) count \>100\*10\^9/l * serum creatinine \<=2.2 mg/dl * serum glutamic oxaloacetic transaminase (sgot), serum glutamic pyruvic transaminase (sgpt) and total bilirubin \<2 x upper limit of normal (uln) * left ventricle ejection fraction \>45% by normal echocardiogram or multiple-gated acquisition (muga) scan * forced expiratory volume of the lung in the first second (fev1) \>60% of predicted or diffusing capacity of the lung for carbon monoxide (dlco) \>45% of predicted * negative for human immunodeficiency virus (hiv) type 1 * women of child bearing potential agreed to use an approved form of contraception. 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 175% of their ideal body weight * 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.
