What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Spectra Optia CMNCDevice

    Also called Spectra Optia Apheresis System CMNC collection procedure

    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.

  • COBE Spectra MNCDevice

    Also called COBE Spectra Apheresis System MNC collection procedure

    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.

  • Granulocyte-colony stimulating factor (G-CSF)Drug

    Also called Mobilization Procedure

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CD34+ Collection Efficiency (CE1 %)

    The primary endpoint is the CD34+ cell collection efficiency (CE) associated with the Mononuclear Cell (CMNC) Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems. CE is a measurement of device performance calculated using donor and blood product blood counts collected immediately before and after the CMNC collection procedure. The collection efficiency for a given cell type is defined as the percent of processed cells of that cell type that are in fact collected.

    Measured: within 5 minutes upon completion of procedure

Secondary outcomes (12)
  1. CD34+ Collection Efficiency (CE2 %)

    Comparison of collection efficiencies associated with the CMNC Cell Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems. CE is a measurement of device performance calculated using donor blood counts immediately before and blood product blood counts immediately after the collection procedure. The collection efficiency for a given cell type is defined as the percent of processed cells of that cell type that are in fact collected.

    Measured: within 5 minutes upon completion of procedure

  2. MNC Collection Efficiency (CE1%)

    Comparison of collection efficiencies associated with the CMNC Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems for MNCs. CE1 is a measurement of device performance calculated using donor and blood product blood counts collected immediately before and after the collection procedure.

  7. MNC Product Contamination/Purity (%) - Platelet Collection Efficiency (CE1 %)

    Comparison of collection efficiencies associated with the CMNC Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems for platelets. CE1 is a measurement of device performance calculated using donor and blood product blood counts collected immediately before and after the collection procedure. The collection efficiency for a given cell type is defined as the percent of processed cells of that cell type that are in fact collected.

    Measured: within 5 minutes upon completion of procedure

  8. MNC Blood Product Volume (mL)

    The produced unit of MNCs collected into the blood bag.

    Measured: within 5 minutes upon completion of procedure

  9. Purity of Plasma Collected for Laboratory Processing of MNC Product - Platelet Concentration in Plasma (10^3/µL)

    A small amount of plasma typically used for processing was collected in a sub-set of collection procedures.

    Measured: within 5 minutes upon completion of procedure

  10. Procedure Time (Minutes)

    Measured: within 5 minutes upon completion of procedure

  11. MNC Collection Efficiency (CE2%)

    Comparison of collection efficiencies associated with the CMNC Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems for MNCs. CE2 is a measurement of device performance calculated using donor blood counts immediately before and blood product counts immediately after the collection procedure and does not average the donor pre- and post-collection counts. The collection efficiency for a given cell type is defined as the percent of processed cells of that cell type that are in fact collected.
