The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled ``Testicular Toxicity: Evaluation During Drug Development.'' The guidance addresses nonclinical findings that may raise concerns of a drug-related adverse effect on the testes, clinical monitoring of adverse testicular effects early in clinical development, and the design and conduct of a safety clinical trial assessing drug-related testicular toxicity. The guidance is intended to assist sponsors developing drugs and therapeutic biologics regulated within the Center for Drug Evaluation and Research to identify nonclinical signals of testicular toxicity and to evaluate the potential for such toxicity in humans.

early in clinical development, and the design and conduct of a safety 
clinical trial assessing drug-related testicular toxicity. The guidance 
is intended to assist sponsors developing drugs and therapeutic 
biologics regulated within the Center for Drug Evaluation and Research 
to identify nonclinical signals of testicular toxicity and to evaluate 
the potential for such toxicity in humans. This guidance finalizes the 
draft guidance of the same name issued on July 17, 2015.

DATES: The announcement of the guidance is published in the Federal 
Register on October 25, 2018.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Testicular Toxicity: Evaluation During Drug Development.'' 
This guidance is intended to help sponsors identify nonclinical signals 
that raise concern regarding the potential for human testicular 
toxicity and to evaluate those signals appropriately in human studies.
    The guidance describes the standard battery of nonclinical studies 
that are used to assess the effects of

[[Page 53883]]

pharmaceuticals on the male reproductive system. The guidance discusses 
findings in nonclinical studies that may increase the level of concern 
for drug-related testicular toxicity. The guidance provides a general 
approach on how to weigh the relevance of nonclinical findings, 
considering factors that can confound the interpretation of these 
findings. If a concerning nonclinical signal is identified, the 
guidance presents suggestions for clinical monitoring when the product 
is initially administered to humans.
    If a reasonable basis for concern of human testicular toxicity 
exists, a trial with a primary objective of evaluating drug-related 
testicular toxicity may be warranted. The guidance provides 
recommendations for the design of such a trial, including study 
conduct, endpoints, and presentation of results. These are general 
recommendations for defining the role of drugs in testicular injury; 
however, the specific details of an individual trial may vary depending 
on the context of use of the drug product.
    This guidance finalizes the draft guidance of the same name issued 
on July 17, 2015 (80 FR 42501). Changes made to the guidance took into 
consideration written and verbal comments received. In addition to 
editorial changes primarily for clarification, the major changes in the 
guidance include revision of information on nonclinical study design 
(including species selection, chronic study design, histopathology 
assessment, sperm quality, and findings that increase concern for 
impaired fertility) and revision of information that, to the extent 
possible, subjects enrolled in the dedicated clinical safety trial 
represent the intended population.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on the evaluation of testicular toxicity during 
drug development. 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 guidance refers to previously approved collections of 
information that 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 collections of information in 21 CFR part 312 have been 
approved under OMB control number 0910-0014. The collections of 
information in 21 CFR parts 50 and 56 (``Protection of Human Subjects: 
Informed Consent and Institutional Review Boards'') have been approved 
under OMB control number 0910-0755.

III. Electronic Access

    Persons with access to the internet may obtain the guidance at
