Public Health Service Guideline on Infectious Disease Issues in Xenotransplantation


OMB# 0910-0456


SUPPORTING STATEMENT


A. Justification

1. Circumstances Making the Collection of Information Necessary


The Food and Drug Administration (FDA) is requesting an extension of Office of Management and Budget (OMB) Control No. 0910-0456 and OMB approval of the information collection provisions contained in a document entitled “Public Health Service Guideline on Infectious Disease Issues in Xenotransplantation” (PHS Guideline). The information provisions are listed below:

The statutory authority to collect this information is provided under sections 351 and 361 of the Public Health Service Act (PHS Act, 42 U.S.C. 262 and 264) and the provisions of the Federal, Food, Drug, and Cosmetic Act (the Act) that apply to drugs (21 U.S.C. 301 et seq.).


In 2001, FDA on behalf of PHS announced the PHS Guideline to address the infectious disease concerns raised by xenotransplantation. The PHS Guideline was jointly developed by agencies within the Department of Health and Human Services (DHHS), including FDA, the Centers for Disease Control and Prevention, the Health Resources and Services Administration, the National Institutes of Health, all parts of PHS as well as the DHHS Office of the Assistant Secretary for Planning and Evaluation. The PHS Guideline is intended to protect the public health and help ensure the safety of using xenotransplantation products in humans by preventing the introduction, transmission, and spread of infectious diseases associated with xenotransplantation.


This collection of information is not related to the American Recovery and Reinvestment Act of 2009 (ARRA).


2. Purpose and Use of the Information Collection


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 collections of information described in this PHS Guideline include the notification of certain information to FDA or to the sponsor, and documentation of certain information associated with xenotransplantation. The collections of information are 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 collections of information are intended to 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 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.


3. Use of Improved Information Technology and Burden Reduction


Sponsors may use computerized storage e.g., (tapes, discs, etc.), microfiche or microfilm to record and store data and information rather than hard copy records if they choose. Notification can be made by phone, fax, or mail. We are not aware of any other improved technology to reduce the burden.


FDA continues to pursue methods of applying technology to further reduce the burden to the respondents of the collection of information.

4. Efforts to Identify Duplication and Use of Similar Information


PHS is the only agency that recommends collecting this information. This information is not available from any other source.

5. Impact on Small Businesses or Other Small Entities


Although FDA must apply the statutory and regulatory requirements equally to all enterprises, FDA does provide special help to small businesses. CBER’s Office of Communication, Outreach, and Development, Division of Manufacturers Assistance and Training, provides assistance to small businesses subject to FDA’s regulatory requirements.


6. Consequences of Collecting the Information Less Frequently


The recommendations provided in the PHS Guideline are intended to diminish the risk of transmission of infectious agents to the xenotransplantation product recipient, to health care workers, and to the general public. Less frequent collection of information would not provide the necessary information needed to help prevent the transmission of infectious agents to xenotransplantation products recipients, to health care workers and to the general public.


There are no technical or legal obstacles to reducing the burden.

7. Special Circumstances Relating to the Guidelines of 5 CFR 1320.5

A sponsor may be required to submit to FDA proprietary trade secret or other confidential information when providing requested information. The confidentiality of information received by FDA is consistent with the Freedom of Information Act (FOIA) and the agency’s published regulations of “Public Information” under 21 CFR Part 20.


Because xenotransplantation is a relatively new area of medical science, potential problems and adverse effects are not well known. Because of the potential risk for cross-species transmission of pathogenic persistent virus, the PHS 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. 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.

8. Comments in Response to the Federal Register Notice and Efforts to Consult Outside the Agency


In accordance with 5 CFR 1320.8(d), FDA published a 60-day notice for public comment in the Federal Register of June 14, 2012 (77 FR 35683). FDA received one comment from the public. The comment was not responsive to the comment request on the four specified aspects of the collection of information and did not provide any data or explanation that would support a change regarding the information collection requirements.

9. Explanation of Any Payment or Gift to Respondents


No payment or gift was provided to respondents.

10. Assurance of Confidentiality provided to Respondents


The confidentiality of information received by FDA is consistent with the Freedom of Information Act (FOIA) and FDA’s regulations under 21 CFR Part 20 (Public Information).

11. Justification for Sensitive Questions


Questions of a sensitive nature are not applicable to this collection of information.


12. Estimates of Annualized Burden Hours and Costs


12a. Annualized Hour Burden Estimate

1 A one-time burden for new respondents to set up a recordkeeping system linking all relevant records. FDA is using one new sponsor for estimation purposes.

2 FDA estimates there is minimal recordkeeping burden associated with maintaining the record system.

3 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 6 of this table); 24 + 8 = 32 monitoring records to document.

4 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.

5 Has not occurred in the past 3 years and is expected to continue to be a rare occurrence.

6 On average two 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 4 of table 6 of this document)

7 FDA estimates there are approximately 2 clinical centers doing xenotransplantation procedures x approximately 25 health care workers involved per center = 50 health care workers.

8 Eight source animal records + 4 recipient records = 12 total records.

1 FDA is using one animal facility or sponsor for estimation purposes.

2 FDA’s records indicate that an average of two INDs is expected to be submitted per year.

3 To our knowledge, has not occurred in the past 3 years and is expected to continue to be a rare occurrence.

4 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.


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. The FDA investigational related applications database tracks the number of INDs and the sponsors of the INDs, and is used to determine the number of active files and the sponsors of the files. Based on data retrieved from that system, there are an estimated 2 respondents who are sponsors of INDs that include protocols for xenotransplantation in humans. Based on FDA’s institutional knowledge, 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 total annual reporting and recordkeeping burden is estimated to be approximately 45 hours. The burden estimates are based on FDA's institutional knowledge and 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.


Information collections in the PHS Guideline not included in tables 1 through 6 can be found under existing regulations and approved under the OMB control numbers as follow: (1) “Current Good Manufacturing Practice for Finished Pharmaceuticals,” 21 CFR 211.1 through 211.208, approved through 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 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 of this document, FDA identifies those collections of information activities that are already encompassed by existing regulations or are consistent with voluntary standards which reflect industry’s usual and customary business practices.

The reporting cost estimate is based on an average pay rate of $64.00/hour. This average is based on the salaries of an upper-level manager, mid-level professional, and clerical support who may be involved in notifying or providing any necessary information. The recordkeeping cost estimate is based on an average pay rate of $58.00/hour of a study coordinator and clinical investigator who are involved with the documentation and maintenance of records. The salary estimates include benefits but no overhead costs.


13. Estimates of Other Total Annual Costs to Respondents and/or Recordkeepers/Capital Costs


There are no capital costs or operating and maintenance costs associated with this collection of information.

14. Annualized Cost to the Federal Government


The estimated annual cost to FDA is $4,160.00.

$4,160.00


The cost to the Federal Government is based on two FDA investigators at an average grade scale of GS-13 ($52.00/hr) who perform on-site inspections. The salary estimate includes benefits but no overhead costs. The cost is also based on an average time to inspect a facility, review the records, and prepare an establishment inspection report. FDA does not plan to inspect them unless the need arises due to specific circumstances. Therefore, FDA is estimating one annual inspection.

15. Explanation for Program Changes or Adjustments


The total annual responses in this request appear to increase from the last extension request in 2009. However, upon investigating the ICR from 2009, it was found that the number of annual responses was entered incorrectly. Therefore, it appears that with this request for extension that the annual responses have increased. But, on the contrary, the annual number of responses, as well as the total burden hours (155.60 to 110.60), have decreased. The decrease (an adjustment) is due to a decrease in the number of sponsors conducting xenotransplantation clinical studies and the corresponding decrease in the number of those clinical studies.

16. Plans for Tabulation and Publication and Project Time Schedule


There are no tabulated results to publish for this information collection.

17. Reason(s) Display of OMB Expiration Date is Inappropriate


FDA is not seeking approval to exempt display of the expiration date of the OMB approval.
