Evaluation of the Spectra Optia® Apheresis System Mononuclear Cell (MNC) Collection Procedure in Healthy Blood Donors

Evaluation of the Spectra Optia® Apheresis System Mononuclear Cell (MNC) Collection Procedure in Healthy Blood Donors

The purpose of this protocol is to characterize the performance of CaridianBCT's Spectra Optia Apheresis System, when used to collect mononuclear cells (MNCs) and cluster of differentiation 34 (CD34) positive cells from healthy nonmobilized blood donors and healthy G-CSF (granulocyte colony stimulating factor) mobilized blood donors, respectively.

• Weight >50<125 Kg (kilogram).
• Male or non-pregnant, non-nursing female.
• General good health, as determined by questionnaire.
• Normal prescreening complete blood count.
• Platelet count>150 x 10^3/uL (microliter) at initial screening and >120 x 10^3/uL immediately prior to leukapheresis.
• Adequate peripheral venous access to allow collection of product.
• Able to read, understand, and sign the informed consent form. Additional Inclusion Criteria for Mobilized Subjects
• If male, be willing to use a condom during sexual relations with a female partner until 48 hours following the last G-CSF injection.
• If female and of childbearing potential, be willing to use a medically acceptable contraceptive until 48 hours following the last G-CSF injection.
