A Pilot Study of Stem Cell Mobilization and Harvesting From the Peripheral Blood Using Filgrastim

Estudio de Tratamiento
Resumen
Patients and volunteers receive seven daily subcutaneous injections of G-CSF. On days 5 and 6 of drug administration, patients have peripheral blood mononuclear cells harvested by leukapheresis. HIV-positive patients are stratified into three cohorts based on CD4 count and presence of symptoms. If no increase in number of harvested stem cells and no grade 4 bone pain toxicity occur in two of the first three patients in a cohort, then the last three patients in that cohort will receive a dose escalation. Patients are followed for 24 weeks.
