1320.3(c) and includes Agency requests or requirements that members of 
the public submit reports, keep records, or provide information to a 
third party. Section 3506(c)(2)(A) of the PRA (44 U.S.C. 3506(c)(2)(A)) 
requires Federal Agencies to provide a 60-day notice in the Federal 
Register concerning each proposed collection of information, including 
each proposed extension of an existing collection of information, 
before submitting the collection to OMB for approval. To comply with 
this requirement, FDA is publishing notice of the proposed collection 
of information set forth in this document.
    With respect to the following collection of information, FDA 
invites comments on these topics: (1) Whether the proposed collection 
of information is necessary for the proper performance of FDA's 
functions, including whether the information will have practical 
utility; (2) the accuracy of FDA's estimate of the burden of the 
proposed collection of information, including the validity of the 
methodology and assumptions used; (3) ways to enhance the quality, 
utility, and clarity of the information to be collected; and (4) ways 
to minimize the burden of the collection of information on respondents, 
including through the use of automated collection techniques, when 
appropriate, and other forms of information technology.

PHS Guideline on Infectious Disease Issues in Xenotransplantation

OMB Control Number 0910-0456--Extension

    This information collection helps support implementation of the 
Department of Health and Human Services' ``PHS Guideline on Infectious 
Disease Issues in Xenotransplantation.'' FDA is authorized to collect 
this information under sections 351 and 361 of the PHS Act (42 U.S.C. 
262 and 264) and provisions of the Federal Food, Drug, and Cosmetic Act 
that apply to drugs (21 U.S.C. 321 et seq.). The guideline, available 
from our website at https://www.fda.gov/media/73803/download was 
developed by the PHS to identify general principles for the prevention 
and control of infectious diseases associated with xenotransplantation 
that may pose a risk to public health. The PHS guideline recommends 
procedures to diminish the risk of transmission of infectious agents to 
the xenotransplantation product recipient and to the general public. 
The PHS guideline is intended to address public health issues raised by 
xenotransplantation, through identification of general principles of 
prevention and control of infectious diseases associated with 
xenotransplantation that may pose a hazard to the public health. The 
collection of information described in this guideline is intended to 
provide general guidance on the following topics: (1) The development 
of xenotransplantation clinical protocols; (2) the preparation of 
submissions to FDA; and (3) the conduct of xenotransplantation clinical 
trials. Also, the collection of information will help ensure that the 
sponsor maintains important information in a cross-referenced system 
that links the relevant records of the xenotransplantation product 
recipient, xenotransplantation product, source animal(s), animal 
procurement center, and significant nosocomial exposures. The PHS 
guideline also describes an occupational health service program for the 
protection of health care workers involved in xenotransplantation 
procedures, caring for xenotransplantation product recipients, and 
performing associated laboratory testing. The PHS guideline is intended 
to protect the public health and to help ensure the safety of using 
xenotransplantation products in humans by preventing the introduction, 
transmission, and spread of infectious diseases associated with 
xenotransplantation.
    The PHS guideline also recommends that certain specimens and 
records be maintained for 50 years beyond the date of the 
xenotransplantation. These include: (1) Records linking each 
xenotransplantation product recipient with relevant health records of 
the source animal, herd or colony, and the specific organ, tissue, or 
cell type included in or used in the manufacture of the product 
(3.2.7.1); (2) aliquots of serum samples from randomly selected animal 
and specific disease investigations (3.4.3.1); (3) source animal 
biological specimens designated for PHS use (3.7.1); animal health 
records (3.7.2), including necropsy results (3.6.4); and (4) 
recipients' biological specimens (4.1.2). The retention period is 
intended to assist health care practitioners and officials in 
surveillance and in tracking the source of an infection, disease, or 
illness that might emerge in the recipient, the source animal, or the 
animal herd or colony after a xenotransplantation.
    The recommendation for maintaining records for 50 years is based on 
clinical experience with several human viruses that have presented 
problems in human to human transplantation and are therefore thought to 
share certain characteristics with viruses that may pose potential 
risks in xenotransplantation. These characteristics include long 
latency periods and the ability to establish persistent infections. 
Several also share the possibility of transmission among individuals 
through intimate contact with human body fluids. Human immunodeficiency 
virus (HIV) and Human T-lymphotropic virus are human retroviruses. 
Retroviruses contain ribonucleic acid that is reverse-transcribed into 
deoxyribonucleic acid (DNA) using an enzyme provided by the virus and 
the human cell machinery. That viral DNA can then be integrated into 
the human cellular DNA. Both viruses establish persistent infections 
and have long latency periods before the onset of disease, 10 years and 
40 to 60 years, respectively. The human hepatitis viruses are not 
retroviruses, but several share with HIV the characteristic that they 
can be transmitted through body fluids, can establish persistent 
infections, and have long latency periods, e.g., approximately 30 years 
for Hepatitis C.
    In addition, the PHS guideline recommends that a record system be 
developed that allows easy, accurate, and rapid linkage of information 
among the specimen archive, the recipient's medical records, and the 
records of the source animal for 50 years. The development of such a 
record system is a one-time burden. Such a system is intended to cross-
reference and locate relevant records of recipients, products, source 
animals, animal procurement centers, and significant nosocomial 
exposures.
    Respondents to this collection of information are the sponsors of 
clinical studies of investigational xenotransplantation products under 
investigational new drug applications (INDs) and xenotransplantation 
product procurement centers, referred to as source animal facilities. 
There are an estimated three respondents who are

[[Page 58668]]

sponsors of INDs that include protocols for xenotransplantation in 
humans and five clinical centers doing xenotransplantation procedures. 
Other respondents for this collection of information are an estimated 
four source animal facilities which provide source xenotransplantation 
product material to sponsors for use in human xenotransplantation 
procedures. These four source animal facilities keep medical records of 
the herds/colonies as well as the medical records of the individual 
source animal(s). The burden estimates are based on FDA's records of 
xenotransplantation-related INDs and estimates of time required to 
complete the various reporting, recordkeeping, and third-party 
disclosure tasks described in the PHS guideline.
    FDA is requesting an extension of OMB approval for the following 
reporting, recordkeeping, and third-party disclosure recommendations in 
the PHS guideline:

\3\ FDA estimates there is minimal recordkeeping burden associated with maintaining the record system.
\4\ Monitoring for sentinel animals (subset representative of herd) plus all source animals. There are
  approximately 6 sentinel animals per herd x 1 herd per facility x 4 facilities = 24 sentinel animals. There
  are approximately 8 source animals per year (see footnote 7 of this table); 24 + 8 = 32 monitoring records to
  document.
\5\ Necropsy for animal deaths of unknown cause estimated to be approximately 2 per herd per year x 1 herd per
  facility x 4 facilities = 8.
\6\ Has not occurred in the past 3 years and is expected to continue to be a rare occurrence.
\7\ On average 2 source animals are used for preparing xenotransplantation product material for one recipient.
  The average number of source animals is 2 source animals per recipient x 4 recipients annually = 8 source
  animals per year. (See footnote 5 of table 6.)
\8\ FDA estimates there are 5 clinical centers doing xenotransplantation procedures x approximately 25 health
  care workers involved per center = 125 health care workers.
\9\ Eight source animal records + 4 recipient records = 12 total records.

\1\ There are no capital costs or operating and maintenance costs associated with this collection of
  information.
\2\ FDA is using one animal facility or sponsor for estimation purposes.
\3\ FDA's records indicate that an average of one IND is expected to be submitted per year.
\4\ To our knowledge, has not occurred in the past 3 years and is expected to continue to be a rare occurrence.
\5\ Based on an estimate of 12 patients treated over a 3 year period, the average number of xenotransplantation
  product recipients per year is estimated to be 4.

    Because of the potential risk for cross-species transmission of 
pathogenic persistent virus, the guideline recommends that health 
records be retained for 50 years. Since these records are medical 
records, the retention of such records for up to 50 years is not 
information subject to the PRA (5 CFR 1320.3(h)(5)). Also, because of 
the limited number of clinical studies with small patient populations, 
the number of records is expected to be insignificant at this time. 
Information collections in this guideline not included in tables 1 
through 6 can be found under existing regulations and approved under 
the OMB control numbers as follows: (1) ``Current Good Manufacturing 
Practice for Finished Pharmaceuticals,'' 21 CFR 211.1 through 211.208, 
approved under OMB control number 0910-0139; (2) ``Investigational New 
Drug Application,'' 21 CFR 312.1 through 312.160, approved under OMB 
control number 0910-0014; and (3) information included in a biologics 
license application, 21 CFR 601.2, approved under OMB control number 
0910-0338. (Although it is possible that a xenotransplantation product 
may not be regulated as a biological product (e.g., it may be regulated 
as a medical device), FDA believes, based on its knowledge and 
experience with xenotransplantation, that any xenotransplantation 
product subject to FDA regulation within the next 3 years will most 
likely be regulated as a biological product.). However, FDA recognized 
that some of the information collections go beyond approved 
collections; assessments for these burdens are included in tables 1 
through 6.
    In table 7, FDA identifies those collection of information 
activities that are already encompassed by existing regulations or are 
consistent with

[[Page 58670]]

voluntary standards which reflect industry's usual and customary 
business practice.
