Study Overview
=================
Brief Summary
-----------------
The purpose of this prospective, randomized, cross-over, multi-center study is to evaluate the performance of the Spectra Optia Apheresis System's CMNC Collection Procedure, compared to the COBE Spectra Apheresis System's MNC Procedure in mobilized healthy donors. Subject safety will be evaluated beginning with mobilization, throughout the collection procedure and for the day following the last collection.

Detailed Description
-----------------
This is a prospective, randomized, cross-over, multi-center study to evaluate the performance of the Spectra Optia system's CMNC Collection Procedure, compared to the COBE Spectra system's MNC Procedure in mobilized healthy donors. Up to 60 subject may be consented to meet the the enrollment target of 20 complete subjects. Eligible subjects will be randomized to receive either the Spectra Optia CMNC or the COBE Spectra MNC collection procedure first, followed by the opposite on the following day. Study participation will be up to 14 days: a 7-day screening period, four days for mobilization, one day for the first MNC collection with additional dose of mobilization, one day for the second MNC collection, and safety follow-up the following day. Subject safety will be evaluated beginning with mobilization, throughout the collection procedure and for the day following the second collection.

| Experimental: Spectra Optia CMNC first, then COBE Spectra MNC<br>Spectra Optia CMNC collection procedure followed by COBE Spectra MNC collection procedure. | Device: Spectra Optia CMNC<br>* The Spectra Optia® Apheresis System is an automated centrifugal system that separates whole blood into its cellular and plasma components. The device is comprised of three major sub-systems, 1) the apheresis machine itself (centrifuge, centrifuge filler, pumps, valves, computerized safety and control systems, etc.), 2) a sterile, single-use, disposable blood tubing set, and 3) embedded software. The Spectra Optia system's investigational CMNC procedure will be used to collect MNC from the peripheral blood.<br>* Other names: Spectra Optia Apheresis System CMNC collection procedure;Device: COBE Spectra MNC<br>* It is also a centrifugal system that separates whole blood into its cellular and plasma components. The COBE Spectra MNC collection procedure is chosen as the comparator device because it is the reference after which design of the Spectra Optia CMNC collection procedure was modeled.<br>* Other names: COBE Spectra Apheresis System MNC collection procedure;Drug: Granulocyte-colony stimulating factor (G-CSF)<br>* Each subject received an injection of the G-CSF approximately equivalent to 10 ug/kg body weight subcutaneous per day for 5 days prior to the MNC collection procedure.<br>* Other names: Mobilization Procedure;|
