Questions and Answers; Draft Guidance for Industry; Availability
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing
the availability of a draft guidance for industry entitled ``Pathology
Peer Review in Nonclinical Toxicology Studies: Questions and Answers.''
This draft guidance represents FDA's current thinking on the management
and conduct of pathology peer review performed during good laboratory
practice (GLP)-
[[Page 37647]]
compliant toxicology studies. When pathology peer review occurs as part
of a nonclinical laboratory study conducted in compliance with GLP
regulations, it should be well-documented. However, documentation
practices during pathology peer review have not been clearly defined
and vary among nonclinical testing facilities. This question-and-answer
(Q&A) draft guidance is intended to clarify FDA's recommendations
concerning the management, conduct, and documentation of pathology peer
review.
DATES: Submit either electronic or written comments on the draft
guidance by September 30, 2019 to ensure that the Agency considers your
comment on this draft guidance before it begins work on the final
version of the guidance.
ADDRESSES: You may submit comments on any guidance at any time as

SUPPLEMENTARY INFORMATION:
I. Background
FDA is announcing the availability of a draft guidance for industry
entitled ``Pathology Peer Review in Nonclinical Toxicology Studies:
Questions and Answers.'' This draft guidance represents FDA's current
thinking on the management and conduct of pathology peer review
performed during GLP-compliant toxicology studies.
The histopathological assessment of tissue samples is one of the
key activities performed during GLP-compliant toxicology studies.
Commonly, histopathological assessment includes an initial read of
[[Page 37648]]
tissue slides by the study pathologist and a subsequent review
(referred to as pathology peer review) by a second pathologist.
Pathology peer review may be particularly useful in situations where
unique or unexpected findings are noted or when the reviewing
pathologist has a particular expertise with a class of compounds. When
pathology peer review occurs as part of a nonclinical laboratory study
conducted in compliance with 21 CFR part 58 (GLP regulations), it
should be well-documented in the study records. However, documentation
practices during pathology peer review have not been clearly defined
and vary among nonclinical testing facilities.
The GLP regulations include general requirements for histopathology
evaluation (for example, it requires that standard operating procedures
be established to cover histopathology), and pathology peer review can
be valuable to the histopathology evaluation during a GLP study even
though it is not specifically addressed in the GLP regulations. This
Q&A draft guidance is intended to clarify FDA's recommendations
concerning the management and conduct of pathology peer review when
performed during GLP-compliant toxicology studies.
This draft guidance is being issued consistent with FDA's good
guidance practices regulation (21 CFR 10.115). The draft guidance, when
finalized, will represent the current thinking of FDA on ``Pathology
Peer Review in Nonclinical Toxicology Studies: Questions and Answers.''
It does not establish any rights for any person and is not binding on
FDA or the public. You can use an alternative approach if it satisfies
the requirements of the applicable statutes and regulations. This
guidance is not subject to Executive Order 12866.
II. Paperwork Reduction Act of 1995
This draft guidance refers to previously approved collections of
information found in FDA regulations. These collections of information
are subject to review by the Office of Management and Budget (OMB)
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The
following collections of information regarding GLP-compliant toxicology
studies have been approved under OMB control number 0910-0119:
Sec. 58.29 related to personnel who conduct nonclinical
laboratory studies;
Sec. 58.35 for preparing quality control units;
Sec. 58.81 for preparing and maintaining standard
operating procedures for testing facilities; pathology peer review
should be planned, conducted, documented, and reported in accordance
with established procedure;
Sec. Sec. 58.120, 58.185, and 58.190 for preparing a
final report for each study, including a protocol and any changes to
the protocol and for maintaining documentation, protocols, and final
reports generated from nonclinical laboratory studies.
