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The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Pathology Peer Review in Nonclinical Toxicology Studies: Questions and Answers.” This draft guidance represents FDA's current thinking on the management and conduct of pathology peer review performed during good laboratory practice (GLP)-Start Printed Page 37647compliant 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 This question-and-answer (Q&A) draft guidance is intended to clarify FDA's recommendations concerning the management, conduct, and documentation of pathology peer review.

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FDA is announcing the availability of a draft guidance for industry entitled “Pathology Peer Review in Nonclinical Toxicology Studies: Questions and Answers.” This draft guidance represents FDA's current thinking on the management and conduct of pathology peer review performed during GLP-compliant toxicology studies.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 Start Printed Page 37648tissue 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:
- § 58.29 related to personnel who conduct nonclinical laboratory studies;
- § 58.35 for preparing quality control units;
- § 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;
- § § 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.
