Definition of Disease-associated Antibodies
• Antibodies that have occurred in response to exposure to disease agents or other antigens
4
CC BBEE RR
Examples of Disease Agents or Antigens
• Chlamydia• Coccidioidomycosis• C-Reactive Protein• Cytomegalovirus (CMV)• Mononucleosis (Epstein-Bar Virus)• Hemophilus influenza• Hepatitis A (Anti-HAV)• Hepatitis B core (Anti-HBc)
– Anti-HBc collections allowed in this category only when donor is known to also have Anti-HBs

Examples of Disease Agents or Antigens (cont.)
• Hepatitis B (Anti-HBs)• Herpes Type I and II• Histoplasmosis• Mumps• Parvovirus B19• Pseudomonas• Respiratory Syncytial Virus (RSV)• Rubella• Rubeola• Toxoplasmosis• Varicella Zoster (VZV)

Immunoglobulin M (IgM) Antibody Collection Program
• Plasma containing IgM antibodies or from donors who do not meet all donor suitability requirements are not covered under a disease-associated antibody program
– Considered disease state donors
– Submit as a Prior Approval Supplement under 601.12(b)
7
CC BBEE RR
Disease-associated Antibody Program
• Manufacturers may implement a program to collect Source Plasma from donors who have detectable levels of disease-associated IgG antibodies
• Donors must meet all donor suitability requirements in 640.63
• Donors should be in good health at time of donation
8
CC BBEE RR
Disease-associated Antibody Program (cont.)
• Donors: – Should have either recovered from the disease or
been exposed to the disease agent but remained asymptomatic
– Possess specific IgG antibodies to the disease agent
• Source Plasma may be used in the manufacture of injectable and noninjectable products
– Examples: IVIG; controls for in vitro diagnostic assays
9
CC BBEE RR
Informed Consent
In addition to the requirements in 640.61, donors:
• Should be informed that their plasma is being collected because it contains a specific antibody
• Should be informed that their antibody level will be monitored periodically to determine if they may continue participating in the program
10
CC BBEE RR
Reporting Program Implementation
• Report in your Annual Report under 601.12(d)
• Include Form FDA 356h
• Annual Report should include statements that:
– Donors met all required suitability criteria for Source Plasma donors in 640.63
– The plasma was collected from donors who have been exposed to the disease agent but are in good health at the time of collection
11
CC BBEE RR
Reporting Program Implementation (cont.)
• Do not need to submit SOPs or the Informed Consent with the Annual Report
• Each program is facility specific
– If implemented at more than one facility, submit a list of facilities and dates of implementation
12
CC BBEE RR
Label Submission
• Submit labels for each pre-existing antibody as a CBE under 601.12(f)(2)
• Immunizing antigen (or antibody) must be on Source Plasma label [640.70(a)(7)]
13
CC BBEE RR
Label Submission (cont.)
• Form FDA 2567
• May submit a base label and include a list of different disease-associated antibodies with an explanation of placement on label
• Submit disease-associated antibody label for each facility if using address of each facility on label
14
CC BBEE RR
Other Naturally Occurring or Pre-Existing IgG Antibodies
• Establishments may implement or expand the program to collect other naturally occurring or pre-existing IgG antibodies
• Donors must meet all suitability requirements in 640.63
15
CC BBEE RR
Other Naturally Occurring or Pre-Existing IgG Antibodies (cont.)
• For donors with other naturally occurring or pre-existing red blood cell antibodies, submit a statement attesting that the donor:
– Is not currently in an immunization program
– Has not been immunized, either deliberately or by transfusion, within the previous 12 months
• Annual report should describe the procedures implemented to address these issues
