Summary

The purpose of this research study is to test the safety and efficacy of a drug called Plerixafor. Plerixafor is approved by the US FDA for use in increasing blood stem cell counts before collection in cancer patients. It is not yet approved for patients with sickle cell disease. The investigators want to find out if Plerixafor can be used to increase cell counts in patients with sickle cell disease.

Women of child-bearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control; abstinence) prior to study entry
Each patient must be willing to participate as a research subject and must sign an informed consent form
and for the duration of study participation. Should a woman become pregnant or
suspect she is pregnant while participating in this study, she should inform
her treating physician immediately

Exclusion Criteria

Patients who are
Receiving or received treatment with an investigational agent within 4 weeks prior to entering the study OR
have not recovered from adverse events due to agents administered more than 4 weeks earlier as determined by the treating physician
Patients with ALT(SGPT) > 2.5 X upper limit of normal
Patients with a creatinine clearance of < 60 ml/min
Patients who have uncontrolled illness including, but not limited to
Ongoing or active infection
Emergency room admission or hospitalization in the past 14 days
Major surgery in the past 30 days
Medical/psychiatric illness/social situations that would limit compliance with study requirements as determined by the treating physician
Female patients who are pregnant or breast-feeding
Patients with active hepatitis B, hepatitis C, or HIV infection
Patients with poor cardiac function as defined by an ejection fraction < 40% are excluded due to potential poor tolerance of the fluid shifts with leukapheresis (only for patients enrolled on second phase of protocol for Leukapheresis)
