Cyclophosphamide for Hematopoietic Stem Cell Mobilization in Patients With a Hematologic Malignancy

Completed · Phase 2

Conditions studied: Hematologic Malignancies

In brief

No prospective randomized trials have evaluated the most efficacious dose of cyclophosphamide to mobilize autologous stem cells. We previously demonstrated that the time to collection of autologous hematopoietic stem cells is 10-12 days following the one dose of cyclophosphamide and daily G-CSF (granulocyte-colony stimulating factor).9 This prospective randomized trial is designed to determine if a lower dose of cyclophosphamide (1.5 gm/m2) will be as efficacious as the intermediate dose (3 gm/m2), based on cell number collected, number of apheresis required and resource utilization.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

All patients must have a pathologic diagnosis of one of the following malignancies:
Non-Hodgkin's Lymphoma, including B- and T-cell lymphoma Multiple Myeloma or another plasma cell dyscrasia (Waldenstrom, Amyloidosis)
The patient must be approved for transplant by the treating Transplant physician.
This must be the patient's FIRST mobilization attempt.
Patients are eligible if an autologous transplant is planned within approximately 12 months from the time of collection of cells.
Prior Treatment: No previous cytotoxic chemotherapy within 4 weeks prior to initiation of therapy. (This does not include immunomodulatory drugs (IMiDs), proteasome inhibitors, monoclonal antibodies or steroids.)
No radiation within 4 weeks of mobilization attempt.
Age >18, and < 75 years
No significant co-morbid medical or psychiatric illness that would significantly compromise the patient's clinical care and chances of survival.
Informed consent must be signed prior to the treatment. Patients must willingly consent after being informed of the procedure to be followed, the nature of the therapy, alternatives, potential benefits, side effects, risks and discomforts. (Human protection committee approval of this protocol and a consent form is required.)

You may not qualify if…

Medical, social, or psychological factors that would prevent the patient from receiving or cooperating with the full course of therapy.
Documented hypersensitivity to any of the drugs used in the protocol.
