Clinical Trial Summary

This study will gather information about the combination the drugs plerixafor with sargramostim in donors of blood-forming cells (stem cells). These stem cells will be collected from the donor and transplanted into their sibling. The investigators believe that the two drugs together will provide enough stem cells for transplantation and may also reduce the risk of graft versus host disease.

Description:

The main purpose of this study is to gather information about the combination the drugs plerixafor with sargramostim in donors of blood-forming cells (stem cells). Stem cells can be taken from the bone marrow of the pelvic bones or from the blood following treatment with drugs called growth factors; sargramostim is such a drug. Once stem cells leave the bone marrow and circulate in the blood, they are called peripheral blood stem cells (PBSCs). These cells can be collected through a routine procedure called apheresis, which involves placing two IVs into the arm which are connected to an apheresis machine; the machine then takes blood from the body, removes the stem cells, and returns the blood to the body.

Normally, a growth factor called filgrastim is given to donors in order to collect the stem cells used for transplantation. However, when stem cells collected using filgrastim are transplanted in patients, a possible unpredictable complication is graft versus host disease. It's thought that using a different growth factor such as sargramostim might reduce the occurrences of graft versus host disease in patients. However, sargramostim alone does not provide as many stem cells for transplantation as other growth factors. Plerixafor is another drug that can increase the number of PBSCs in a donor, but like with sargramostim, plerixafor alone does not always provide enough stem cells. This is why sargramostim and plerixafor are being combined in this study: the investigators believe that the two drugs together will provide enough stem cells for transplantation and may also reduce the risk of graft versus host disease.

• Chronic myelogenous leukemia (CML) in accelerated or second chronic phase,

• Non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) in 2nd or greater complete remission, partial remission, or refractory relapse,

• Chronic lymphocytic leukemia (CLL), Rai Stage 2-4, failing at least 2 prior regimens, OR

• Multiple myeloma (MM), Stage 2-3.

• Myeloproliferative disorder or neoplasm

• Recipient must have adequate cardiac function with a left ventricular ejection fraction = 40%.

• Recipient must have adequate pulmonary function defined as NO severe or symptomatic restrictive or obstructive lung disease, and formal pulmonary function testing showing an FEV1 =50% of predicted and a DLCO =40% of predicted, corrected for hemoglobin.

• Recipient must have adequate renal function as defined by a serum creatinine clearance (Cockcroft-Gault equation)of =56 ml/min for females and =64 ml/min for males of normal

• Recipient must have adequate hepatic function as defined by a total bilirubin <2x normal or absence of hepatic fibrosis/cirrhosis.

• Recipient must have adequate neurologic function as defined by NO evidence of a severe central or peripheral neurologic abnormality. Patients with a history of previous CNS tumor involvement are eligible provided they are without symptoms or signs and the CNS is now free of disease on lumbar puncture and CT scan of the brain.

• Recipient must have no evidence of active infection at the time of the transplant preparative regimen or at time of transplantation.

• Recipient must be HIV-1&2 antibody and HTLV-I & II antibody sero-negative, by FDA licensed test.

• Recipient has an ECOG performance status of 0 or 1.

• Recipient must demonstrate ability to be compliant with medical regimen.

• Recipient must not have active alcohol or substance abuse within 6 months of study entry.

• Recipient must not be enrolled on another investigational agent concurrently.

• Recipient must not have any medical condition, which, in the opinion of the clinical investigator, would interfere with the evaluation of the patient.

• Recipient must have a life expectancy of greater than 4 weeks.

• Both men and women and members of all races and ethnic groups are eligible for this trial.

• Donor may not be receiving any other investigational agents.

• Donor may not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to plerixafor or GM-CSF, or known hypersensitivity to yeast-derived products or any component of the product.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of donors requiring a second collection to obtain a minimum CD34/Kg (2 x 10^6) necessary for allogeneic stem cell transplantation	The primary endpoint is to reduce the number of donors treated with GM-CSF who require a second collection to obtain a minimum CD34/Kg (2 x 106) necessary for allogeneic stem cell transplantation when compared to historic controls mobilized with GM-CSF or plerixafor alone. A reduction in failed first leukapheresis from 40% to less than 10% as seen with G-CSF alone would be considered clinically meaningful.	Up to 6 days
Secondary	Proportion of donors who experience grade 3-4 infusion toxicity	Infusional toxicity will be evaluated by measuring the patient's blood pressure, heart rate, respirations and temperature one hour prior to the allograft infusion and then 15 minutes, 30 minutes, one hour, 2 hours, and 4 hours, and 6 hours post infusion. Donors will have vital signs collected at each time point. EKGs will be performed immediately prior to IV AMD3100 and one hour after infusion.	30 days after completion of therapy (estimated to be 36 days)
Secondary	Number of donors who mobilize = 2x10^6 CD34+ cells/Kg recipient weight safely following one or two aphereses		Up to 6 days
Secondary	Determine if peripheral blood stem cell products collected after mobilization with IV plerixafor can be used safely for hematopoietic cell transplantation in HLA-matched recipients as measured by neutrophil engraftment (recipient only)		Day 21
Secondary	Kinetics of immune reconstitution as measured by neutrophil engraftment (recipient only)		Day 100
Secondary	Rate of acute Graft vs. Host Disease (GvHD) (recipient only)	Incidence and severity of acute GVHD will be assessed based on the Seattle criteria. Attempts should be made to confirm the diagnosis pathologically by biopsy of target organ(s).	Up through Day 100
Secondary	Transplant related mortality (recipient only)	Death that results from a transplant procedure related complication (e.g. infection, organ failure, hemorrhage, GVHD) rather than from relapse of the underlying disease or an unrelated cause.	100 days
Secondary	Relapse, disease progression and death of any cause (recipient only)	Determine relapse, disease progression and death of any cause	1 year
Secondary	Proportion of donors who reach 5x10^6 CD34+ cells/Kg recipient weight in 1 or 2 aphereses		6 days
Secondary	Kinetics of immune reconstitution as measured by platelet engraftment (recipient only)		100 days
Secondary	Rate of chronic Graft vs. Host Disease (GvHD) (recipient only)	Incidence and severity of chronic GVHD will be assessed based on the NIH consensus criteria and global severity scoring system. Attempts should be made to confirm the diagnosis pathologically by biopsy of target organ(s).	Day 100-1 year
