NCT01123499

Brief Summary

Background:

  • Many treatments for immune system disorders involve the use of stem cells that have been collected from blood marrow. To obtain these stem cells without surgery, individuals receive granulocyte colony-stimulating factor (G-CSF) to encourage the production of stem cells that can be collected through blood donations. However, not all patients or normal donors respond to G-CSF alone.
  • Plerixafor, recently approved by the Food and Drug Administration, is different from G-CSF but also allows stem cells to be collected from donated blood. However, more research is needed on the quality and viability of the stem cells collected after using both G-CSF and plerixafor. Objectives: \- To collect and study the blood cells produced after treatment with G-CSF and plerixafor in healthy volunteers. Eligibility: \- Healthy volunteers between 18 and 65 years of age who are eligible to donate blood. Design:
  • Participants will be screened with a medical history, physical examination, and initial blood tests.
  • At the start of the study cycle, participants will receive daily morning injections of G-CSF for 5 days. These may be given at the clinical center or by the participant after teaching, depending on the participant s preference.
  • On the morning of Day 4, participants will visit the clinical center to provide a blood sample after the injection. On the evening of Day 4, participants will receive an injection of plerixafor.
  • Participants will have the final injection of G-CSF on the morning of Day 5, and will provide another blood sample.
  • On Day 5, participants will have apheresis to separate the stem cells from the rest of the blood. The apheresis may take up to 5 hours to complete.
  • The study will end after a follow-up phone call 7 to 14 days after the apheresis procedure.

You may qualify if:

  • To be eligible to participate in this study, a subject must satisfy all of the following criteria:
  • \. The subject must be a healthy adult aged 18-65 years, and weighing at least 50 kg.
  • , The subject must have normal renal function (creatinine \<1.5 mg/dL; \<1 plus proteinuria); normal hepatic function (bilirubin \< 1.5 mg/dL); normal hematologic function (WBC greater than or equal to 2500/mm(3); granulocytes greater than or equal to 1200/mm(3); platelets greater than or equal to 120,000; hematocrit greater than or equal to 38).
  • \. A female of childbearing potential may be entered if she is using 1 or 2 forms of effective contraception (depending on the type of contraception), and has a negative serum pregnancy test within 1 week of beginning G-CSF administration. She must continue with the effective contraception 3 months after receiving plerixafor
  • \. The subject must be willing to allow blood cell samples to be stored.

You may not qualify if:

  • A subject will be ineligible to participate in this study if any of the following criteria are met:
  • The subject has a temperature \> 38 degrees Celsius, or WBC \> 9000/mm(3).
  • A female who is pregnant or lactating as determined by history and/or pregnancy test.
  • The subject has a history of vasculitis, uncontrolled hypertension, or symptomatic coronary artery disease, or similar disorders.

  • The subject lacks peripheral venous access in arm veins adequate for apheresis.
  • The subject is currently participating in other research studies.
  • The subject may be excluded at the discretion of the Principal Investigator (PI).
