Improving White Blood Cell Collection From Healthy Donors
NCT01553214
This study is recruiting at 1 US site in 1 state, according to its ClinicalTrials.gov record last updated .
Summary
Background: - White blood cells called granulocytes help the body fight infection. People who have had chemotherapy or bone marrow transplants may have very low numbers of these cells. Transfusions of these cells can help improve the body's ability to fight infection. However, most of the cells are located in the bone marrow or spleen, and are hard to collect from healthy donors. Two drugs, filgrastim and dexamethasone, can help move the cells to the bloodstream to be collected by apheresis. Researchers want to study the best ways to collect these white blood cells.
