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.

  3. Adequate dual peripheral venous access

  4. Acceptable prescreening laboratory results prior to MNC mobilization as specified below:

    a) WBC 3,500 - 10,800/µL

    b) Hematocrit 38% - 56%

    c) Platelets 150,000 - 400,000/µL

    d) Coagulation tests:

Primary Outcome Measures
NameTimeMethod
CD34+ Collection Efficiency (CE1 %)within 5 minutes upon completion of procedure

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.

Secondary Outcome Measures
NameTimeMethod
CD34+ Per kg of Body Weightwithin 5 minutes upon completion of procedure
MNC Blood Product Volume (mL)within 5 minutes upon completion of procedure

The produced unit of MNCs collected into the blood bag.

MNC Product Contamination/Purity (%) - Hematocrit (%)within 5 minutes upon completion of procedure
MNC Product Contamination/Purity (%) - Platelet Concentration (10^3/µL)within 5 minutes upon completion of procedure
Purity of Plasma Collected for Laboratory Processing of MNC Product - Platelet Concentration in Plasma (10^3/µL)within 5 minutes upon completion of procedure

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

MNC Collection Efficiency (CE2%)within 5 minutes upon completion of procedure

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.

CD34+ Collection Efficiency (CE2 %)within 5 minutes upon completion of procedure

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.

MNC Collection Efficiency (CE1%)within 5 minutes upon completion of procedure

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. 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.
