To determine the safety of stem cell harvesting after administration of filgrastim ( G-CSF ) to mobilize bone marrow stem cells into the peripheral blood in patients at various stages of HIV-1 infection as well as in HIV-negative volunteers. To determine the surface phenotypic and functional characteristics as well as the viral load in the stem cells obtained following this procedure. 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.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
24 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
