An Evaluation of the Spectra Optia CMNC Collection Procedure

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.

Inclusion criteria

• ≥ 18 and ≤ 50 years of age
• Healthy blood donor criteria as defined by the American Associate of Blood Banks (AABB)

a) Note: Subjects who are deferred from volunteer donations because of travel restrictions, piercings or tattoos may participate in the study

• Adequate dual peripheral venous access
• 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:

i. PT 9.0 - 13.0 seconds

ii. PTT 23.4 - 41.8 seconds

e) Serum electrolytes:

i. Potassium 3.6 - 5.1 mmol/L

ii. Serum Calcium 8.5 mg/dL - 10.3 mg/dL

f) Renal function: Serum creatinine ≤ 1.5 mg/dL

NOTE: up to two laboratory results may fall out of the ranges listed above if, in the judgment of the investigator, they do not constitute a significant risk to the subject.
